Description

Technical Field

[0001] This utility model relates to a cage and its bearing, belonging to the field of bearing technology. Background Technology

[0002] Traditional cage designs often employ simple upper and lower cover structures connected by bolts or other fasteners. While these may meet basic transmission requirements, long-term operation limits bearing efficiency and lifespan due to friction and wear. In particular, when bearings bear heavy loads, friction between the balls and the retaining grooves increases significantly. This not only accelerates wear on both the balls and the retaining grooves but also generates substantial heat, affecting bearing stability and reliability. Furthermore, traditional cage designs are inadequate in terms of lubrication supply and retention, often requiring frequent lubrication changes or top-ups. This increases maintenance costs and hinders continuous bearing operation. Utility Model Content

[0003] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a cage and its bearing to reduce friction and wear, and improve the operating efficiency and life of the bearing.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a retainer, comprising:

[0005] Lower cage;

[0006] An upper retainer is located above a lower retainer and is detachably mounted on the lower retainer.

[0007] Multiple placement slots are provided between the lower retainer and the upper retainer;

[0008] Each of the placement slots is rotatably connected with ball bearings.

[0009] Preferably, multiple placement slots are circumferentially distributed between the lower retainer and the upper retainer.

[0010] Preferably, both the inner and outer sides of the ball penetrate the sidewall of the placement groove and extend to the outside.

[0011] Preferably, a plurality of connecting posts are evenly distributed on the side of the lower retainer near the upper retainer;

[0012] The upper retainer has multiple connecting slots evenly distributed on the side near the lower retainer;

[0013] When the upper retainer is installed on the lower retainer, the connecting post is inserted into the inside of the connecting groove;

[0014] The connecting post is secured inside the connecting groove by a locking fastener.

[0015] Preferably, the locking device is a bolt, which is disposed on the upper side of the upper retainer, and the threaded end of the bolt extends into the connecting groove and engages with the connecting post.

[0016] Preferably, both sides of the connecting column are fixedly connected with protruding ribs;

[0017] Rib grooves are provided on both sides of the connecting groove;

[0018] When the connecting post is inserted into the inside of the connecting groove, the protruding rib is inserted into the inside of the rib groove.

[0038] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0039] Example 1

[0040] like Figures 1-6 As shown, in this embodiment, a retainer is provided, including a lower retainer 1 and an upper retainer 2; the upper retainer 2 is located above the lower retainer 1 and is detachably mounted on the lower retainer 1; a plurality of placement slots 3 are provided between the lower retainer 1 and the upper retainer 2, and the plurality of placement slots 3 are circumferentially distributed between the lower retainer 1 and the upper retainer 2; wherein, each placement slot 3 is rotatably connected to a ball bearing 4, and the inner and outer sides of the ball bearing 4 penetrate the side wall of the placement slot 3 and extend to the outside.

[0041] Work process:

[0042] The upper retainer 2 is mounted on the lower retainer 1, and a tight fit is achieved through a detachable connection. At this time, multiple ball bearings 4 have been pre-placed in the placement groove 3 between the lower retainer 1 and the upper retainer 2.

[0043] As the balls 4 rotate within the placement groove 3, this rotation not only effectively supports the load but also significantly reduces friction and wear, improving the bearing's operating efficiency and lifespan. Because the balls 4 are circumferentially distributed throughout the cage, they can evenly distribute the load, ensuring stability and reliability.

[0044] Example 2

[0045] like Figures 1-6 As shown, based on Embodiment 1, in order to install the upper retainer 2 on the lower retainer 1, the lower retainer 1 has a plurality of connecting posts 5 evenly distributed on the side near the upper retainer 2; the upper retainer 2 has a plurality of connecting slots 6 evenly distributed on the side near the lower retainer 1.

[0046] When the upper retainer 2 is installed on the lower retainer 1, the connecting post 5 is inserted into the inside of the connecting groove 6;

[0047] The connecting post 5 is locked inside the connecting groove 6 by a locking fastener 7, which is a bolt. The bolt is located on the upper side of the upper retainer 2, and the threaded end of the bolt extends into the connecting groove 6 and engages with the connecting post 5.

[0048] Both sides of the connecting column 5 are fixedly connected with protruding ribs 8;

[0049] Rib grooves 9 are provided on both sides of the connecting groove 6;

[0050] When the connecting post 5 is inserted into the connecting groove 6, the protruding rib 8 is inserted into the rib groove 9.

[0051] The lower retainer 1, connecting column 5, and protruding rib 8 are integrally formed.

[0052] Work process:

[0053] Based on Embodiment 1, the connection process between the upper retainer 2 and the lower retainer 1 in this embodiment is as follows:

[0054] First, align the side of the upper retainer 2 closest to the lower retainer 1 with the connecting post 5 of the lower retainer 1, ensuring that the connecting groove 6 corresponds one-to-one with the connecting post 5. Next, insert the connecting post 5 into the connecting groove 6, ensuring that the rib 8 mates with the rib groove 9. At this point, the upper retainer 2 is initially installed on the lower retainer 1; then, use the locking fastener 7 (bolt) to secure the connecting post 5 inside the connecting groove 6. By rotating the bolt, a tight fit is achieved between it and the connecting post 5, providing a tightening force. Thus, the upper retainer 2 is securely installed on the lower retainer 1, forming a stable connection structure. This not only ensures a stable connection between the upper retainer 2 and the lower retainer 1, improving the overall strength and stability of the retainer, but also, due to the design of the connecting post 5 and the connecting groove 6, makes the disassembly and replacement of the upper retainer 2 simpler and more convenient.

[0055] Example 3

[0056] like Figure 1 , Figure 2 , Figure 4 as well as Figure 6 As shown, based on the above embodiments, in this embodiment, both the lower retainer 1 and the upper retainer 2 are provided with multiple oil grooves 10, and one end of the oil groove 10 is connected to the corresponding placement groove 3;

[0057] When the ball 4 rotates inside the placement groove 3, the lubricating oil in the oil groove 10 can coat the surface of the ball 4.

[0058] The end of the oil tank 10 away from the placement groove 3 is engaged with a plug cap 11 for sealing the lubricating oil in the oil tank 10. The outer end of the plug cap 11 is provided with a countersunk hexagonal hole.

[0059] Work process:

[0060] Based on the above embodiments, this embodiment adds a lubricant coating step to the working process. The specific process is as follows:

[0061] First, the upper retainer 2 is securely mounted on the lower retainer 1 through the cooperation of the connecting post 5 and the connecting groove 6, and the locking fastener 7. An appropriate amount of lubricating oil is filled in the oil groove 10. The lubricating oil smoothly enters the placement groove 3 and coats the surface of the ball bearing 4 through the connection between the oil groove 10 and the placement groove 3. To ensure the durability of the lubricating oil and prevent leakage, a plug cap 11 is installed at the end of the oil groove 10 away from the placement groove 3. The plug cap 11 engages with the oil groove 10, forming an effective seal.

[0062] The balls 4 roll within the placement groove 3, while the lubricating oil in the oil groove 10 continuously coats the surface of the balls 4, reducing friction and wear, and improving the bearing's operating efficiency and lifespan. Due to the sealing effect of the plug cap 11, the lubricating oil can remain in the oil groove 10 for a long time without frequent replacement or replenishment.
