Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a low-temperature self-lubricating cage. Background Technology

[0002] Bearings are essential basic components in mechanical equipment and are widely used in various industrial fields such as automobiles, aerospace, railways, wind power, and machine tools. The main function of bearings is to support rotating shafts and reduce friction and wear during rotation, thereby ensuring the stable operation of mechanical systems and extending the service life of equipment. Bearings are usually composed of an inner ring, an outer ring, rolling elements (balls, needle rollers, or cylindrical rollers), and a cage. The cage, also known as a spacer or isolator, is a key auxiliary component in bearings, and its design and performance have a significant impact on the overall performance of the bearing.

[0003] However, existing cages still have some shortcomings and areas for improvement in actual use. During long-term use of the bearing, the friction and heat borne by the cage itself can affect the overall performance of the bearing. The conventional solution is to use lubricating oil for frequent lubrication to maintain good performance. However, if it is not maintained for a long time, the overall performance will decline. Therefore, those skilled in the art provide a low-temperature self-lubricating cage to solve the problems mentioned in the background art. Utility Model Content

This retainer features lubrication grooves at the center of both the inner and outer side walls of the main body, which can be used for heat dissipation and temporary storage of lubricating oil, providing continuous lubrication during use. Furthermore, by using Teflon and polyimide as the materials for the low-temperature resistant layer and the self-lubricating layer, the coefficient of friction generated during use is reduced, and continuous lubrication of the internal balls is provided, making it suitable for operation at low temperatures.

These grooves can be used for heat dissipation and temporary storage of lubricating oil, providing continuous lubrication during use.

Furthermore, by using Teflon and polyimide as the materials for the low-temperature resistant layer and the self-lubricating layer, the coefficient of friction generated during use can be reduced, and the internal balls can be continuously lubricated. This also makes the system suitable for operation at low temperatures.

[0008] Furthermore, the lubrication groove is semi-circular in shape;

[0012] Furthermore, the edges of the side walls of the multiple ball-splitting holes are all rounded.

[0013] The above technical solutions reduce friction.

[0014] Furthermore, the self-lubricating layer is made of polyimide;

[0015] The above technical solution has excellent wear resistance and low coefficient of friction, and is highly resistant to most acids, alkalis and organic solutions.

[0016] Furthermore, the low-temperature resistant layer is made of Teflon;
