Types of slip rings commonly used for machining parts

Among all electrome chanical products,except for a few areas where slip rings require thousands of components, the majority of slip rings used in these fields are not very complex products.Apart from bearings, brushes (carbon brushes), and wires, the number of components in other parts of the slip ring is relatively small. There are also many processing techniques for these parts, including injection molded parts,stamped parts, pressure (casting) castings, and machined parts. The most commonly used slip ring models are injection molded parts. The capsule hollow shaft series standard slip ring with the highest annual production and sales volume of JINPAT uses a large number of injection molded internal and external components.

 

Stamped parts, on the other hand, are mainly made of slip ring shells. The standard micro and ultra micro slip rings of JINPAT use stainless steel shell stamped parts. The use of stainless steel shell stamped parts can significantly improve the impact resistance and other performance of the slip ring. The same principle applies to using die castings as the outer shell of slip rings. Due to the harsh working environment, most of the engineering machinery slip rings developed by JINPAT are mainly made of die castings.

 

The large-scale use of machined parts as stator and rotor components for slip rings includes gas-liquid slip rings,fiber optic slip rings, high-frequency slip rings, and some customized slip rings. Among them, the standard model of the JINPAT gas-liquid series slip ring mainly uses aluminum alloy material for its main components, while its customized version mostly uses steel. Therefore, in general, the customized version of the JINPAT gas-liquid slip ring weighs much more than the standard model, and of course, it can withstand much greater gas-liquid pressure.

 

Let’s take a look at fiber optic slip rings and high-frequency slip rings. Whether they are standard products or customized products, the main components of the stator and rotor of these two types of slip rings are made of stainless steel material. However, due to the different transmission media, the internal structure of these two products may also be slightly different. For example, high-frequency slip rings do not require a speed exceeding 100rpm, while the speed of fiber optic slip rings may reach 20000rpm.Therefore, the requirements for machining are not the same. Obviously, due to the higher speed of fiber optic slip rings, their requirements for machining are also higher.

JINPAT slip ring helps the development of the construction machinery industry in 2024

Engineering machinery slip rings have always been a key product of JINPAT, with an annual production of nearly 10000 sets of different models in this series. Among these engineering machinery slip rings, there are both low-voltage slip rings for vehicle use and high-voltage high-power slip rings for offshore heavy equipment. As an established supplier in the field of engineering machinery slip rings, JINPAT still releases several new products every year. Recently, JINPAT has two new products to be delivered to customers. Let’s briefly introduce them.

 

Firstly, let’s take a look at the slip ring used on the top of the JINPAT excavator. As excavators are often used outdoors,this one has a higher level of protection to assist in stable operation. This series of products mostly use a semi enclosed cylindrical shell, and for ease of installation, its volume is not too large. In terms of electrical performance, in order to achieve normal operation of the equipment, the working voltage of this slip ring from JINPAT has reached 650VAC.

 

The reason why its voltage has increased so greatly is that this model of product is specifically developed for the top of excavators with super strong lifting capacity. The addition of high voltage and high current makes the power transmission capacity of this type of slip ring reach 50KW. In addition to this new product developed for heavy-duty excavators, JINPAT has also launched a new type of marine crane slip ring this year. Due to the confidentiality requirements of customers, it is not convenient to disclose its model here. It is also a high current slip ring.

 

Marine cranes are the most common construction machinery in offshore heavy industry equipment. Due to the need to ensure long-term reliability, the protection level of the marine crane slip ring is generally relatively high. JINPAT, the latest marine crane slip ring,has a protection level of IP65. Its power module includes one 250A current path and three 40A current paths, with a working voltage of 230 VAC. In order to ensure the safety of the equipment on the appearance, stainless steel casing design is adopted, and the design complies with EN-IEC61439.

 

Like most slip rings from JINPAT, the parameters of this product are highly customized based on the characteristics of the terminal. For excavators, which are relatively simple construction machinery, JINPAT’s engineering team is already familiar with customizing slip rings for them. With the electrification of the field of engineering machinery slip rings, more and more integrated high-voltage and high-power engineering machinery slip rings will appear in a large number of new energy engineering machinery. In this technical field, JINPAT is also at the forefront of international slip ring manufacturers.

JINPAT Survey Robot slip ring

In sewer surveys or outdoor multifunctional robots, conductive slip rings are installed on the robot’s gimbal or control center for power and signal transmission. Some more advanced robots also require the integration of a single-mode fiber optic slip ring inside the conductive slip ring to achieve the ability to transmit high-speed data over longer distances. Taking the sewer robot used for survey as an example, the conductive slip ring it uses generally integrates one SDI high-definition video signal path. In addition, some special robots may also integrate infrared cameras in their cameras, so their corresponding conductive slip ring also needs to add corresponding paths to support the infrared video signal path.

 

When the situation of the scene that needs to be surveyed is unclear, this type of survey robot with high-definition or infrared cameras can be used for reconnaissance to determine the basic situation in the scene. If this type of survey sewer robot integrates harmful gas sensors, the reconnaissance effect will be better.

 

In order to obtain more accurate information about the robot’s surroundings, many firefighting robots are equipped with 360 ° optical framing or other types of sensors, so conductive slip rings need to be integrated in these firefighting robots. As a well-known manufacturer of conductive slip rings in the industry, JINPAT has the ability to develop conductive slip rings for various types of robots. JINPAT has developed over a hundred corresponding conductive slip ring product cases for various types of sewer survey robots and outdoor robots such as firefighting.

JINPAT continuously explores new technologies in slip rings

In this era of constant innovation,survival in the competitive market requires relentless exploration and innovation in all product categories. As a company with nearly 30 years of experience in the slip ring industry, JINPAT firmly believes in this truth and has been committed to technological innovation in its independently developed slip ring products for many years. The research and development team at JINPAT has always maintained vitality and innovation in their pursuit of exploring and applying new technologies.

 

In terms of improving, modifying, or updating slip rings, adjustments are continuously made based on customer feedback. The larger the production volume and the wider the application of the conductive slip rings, the higher the frequency of technological improvements.As early as 2019, JINPAT conducted a technological overhaul of the plug-in slip rings. Plug-in slip rings emerged as alternatives to mercury slip rings, but they often need to withstand power voltage and high currents in extremely small volumes. After prolonged high-speed operation in such environments, plug-in slip rings can encounter issues such as overheating.

 

The R&D team at JINPAT promptly conducts fault analysis on slip rings encountering technical problems and swiftly explores new technical solutions. After a period of research and improvement by the team, the optimal solution was determined to be the new standard plug-in slip ring. JINPAT’s Technology Testing Center is responsible for testing the newly structured plug-in slip rings.

 

The latest generation of slip rings has successfully passed a series of performance tests, including lifespan tests,while enduring power electricity, fully meeting design standards. They have shown significant improvements over the previous generation of plug-in slip rings in electrical performance, temperature resistance, and other aspects.Currently, JINPAT’s new generation plug-in slip rings are selling well in various industries, becoming the new generation of popular accessories.

 

In order to maintain an unbeatable position in the fierce market competition, JINPAT always adheres to independent research and development of new slip ring technologies. Its precision conductive slip rings are sold in over a hundred countries and regions globally, providing thousands of individuals and enterprises with cost-effective rotating conductive solutions.

JINPAT Temperature Resistant Conductive Slip Ring

Temperature resistance is an important basic performance of many electromechanical equipment. As a component widely used in electromechanical equipment, conductive slip rings sometimes need to have certain temperature resistance performance. For example, in some engineering machinery specially tuned for harsh conditions, the conductive slip rings used require temperature resistance to meet the requirements of operating in the cold areas of Siberia and the hot and rainy regions of Brazil. As an international veteran slip ring manufacturer, JINPAT has developed many conductive slip rings with high and low temperature resistance.

In addition to extreme high and low temperature environments in natural states, many electromechanical equipment operates in artificially set special high temperature environments. The conductive slip rings used on these devices also need to have the same temperature resistance performance as the equipment. In order to achieve the corresponding level of high and low temperature resistance performance, these conductive slip rings require much stricter material selection for key components such as housing, bearings, and brush wires compared to ordinary conductive slip rings. Of course, their mechanism design is also different from ordinary slip rings.

In the temperature resistant conductive slip rings developed by JINPAT, there is a category of products that operate in extreme high and low temperature environments for a long time. Taking the high-temperature roller conductive slip ring developed by JINPAT as an example,it operates in an environment with a constant temperature above 100℃ for a long time. In order to develop this product, JINPAT collaborated with a constant temperature box manufacturer to specially develop an ultra-high-temperature constant temperature life test bench and completed its full-life test overseveral months. However, temperatures above 100℃ do not reach the temperature limit of some electromechanical equipment, and some conductive slip rings may be immersed in environments with temperatures exceeding 200℃.

With the experience of developing high-temperature roller conductive slip rings above 100℃, JINPAT continues to develop slip rings suitable for higher temperature use. This conductive slip ring from JINPAT, which can operate in an environment with superheated silicone oil above 200℃, is a typical successful case. Its model number is LPT012-0802-HT, which is a relatively small-sized product. In order to better observe the wear of the friction pairof the conductive slip ring, this model product is designed with an opening onthe housing, similar to the ultra-high-speed conductive slip ring developed byJINPAT, but with different purposes. The former is used for observation, while the latter is used for observation, heat dissipation, and introduction of cold air.

In addition to conductive slip rings used in specific scenarios or equipment, many conductive slip rings also have very high requirements for temperature shock resistance. Many models of conductive slip rings require the ability to withstand short-term -60℃ to +120℃ temperature shock during design, while some products also require the conductive slip rings to withstand short-term temperature shock of -100℃ to +180℃ in a vacuum environment. With complete high and low-temperature test equipment and an experienced engineering technical team, JINPAT also has the capability to design and develop such conductive slip rings.

JINPAT Pneumatic and Hydraulic Integrated Slip Ring Technology Analysis

JINPAT has been deeply involved in the slip ring industry for nearly 30 years and has long possessed the technical strength to independently develop pneumatic and hydraulic integrated slip rings. In the field of pneumatic and hydraulic integration, JINPAT has mastered several key core technologies, capable of providing various new technical solutions such as integrating pneumatic, hydraulic, and other signal modules to meet the demands of new conductive mechanical equipment.

 

Among numerous types of slip rings,pneumatic and hydraulic slip rings are relatively unique in function. They are typically used for the transmission of gases and liquids, providing raw material supply, equipment cooling lubrication, and equipment driving power to application terminals. Generally, pneumatic and hydraulic slip rings are integrated into other types of slip rings. The LPPL000-36A-0106-1502-0301-E2slip ring is a multifunctional pneumatic and hydraulic + electric + signal combination slip ring. Its pneumatic and hydraulic slip ring module features 36air passages, with a total length of 842mm and a maximum diameter of 220mm,with pneumatic pipes of G3/8″ specification at P10mm.

 

The main materials of pneumatic and hydraulic slip rings are metal, primarily lightweight aluminum alloys and various grades of stainless steel. Aluminum alloy pneumatic and hydraulic slip rings have unique advantages in light weighting, but their pressure tolerance is lower compared to stainless steel, so they are generally used more for transmitting air or liquid media within a certain pressure range. On the other hand, stainless steel pneumatic and hydraulic slip rings far exceed aluminum alloys in hardness and other aspects, so pneumatic and hydraulic slip rings on the market that can withstand higher pressures are mostly made of stainless steel. JINPAT also develops high-pressure-resistant pneumatic and hydraulic slip rings using stainless steel materials.

 

The difference in materials determines the different pressure tolerances of pneumatic and hydraulic slip rings. Therefore,when in use, pneumatic and hydraulic slip rings should operate within their designed pressure ranges. If the pressure of the transmitted gas or liquid exceeds the designed pressure tolerance of the pneumatic and hydraulic slip ring, it may lead to damage and pose safety hazards, which is one of the important precautions for using pneumatic and hydraulic slip rings.

 

The service life of pneumatic and hydraulic slip rings is also influenced by the chemical properties of the transmission medium. Generally, the chemical properties of compressed air, water,lubricating oil, and coolant are relatively stable and will not corrode the interior of aluminum alloy or stainless steel pneumatic and hydraulic slip rings. In some cases of JINPAT, some customers use pneumatic and hydraulic slip rings to transmit corrosive liquids. During later maintenance, a large amount of rust residue is cleaned from the interior, which affects the smooth rotation of pneumatic and hydraulic slip rings and shortens their lifespan, even leading to scrapping.
