Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to a high load-bearing bearing. Background Technology

[0002] Bearings are components used to support shafts and allow them to rotate. They are widely used in various mechanical equipment, such as automobiles, airplanes, trains, motors, and industrial machinery, and play a vital role in transmission systems, steering systems, suspension systems, and other aspects.

[0003] As disclosed in announcement number CN220816257U, a high-load-bearing deep groove ball bearing includes: an outer ring and an inner ring, with balls rollingly connected between them; a load-bearing mechanism disposed on the inner side of the outer ring; and a support mechanism disposed on the outer side of the outer ring. The load-bearing mechanism includes a cage, which is movably mounted on the outer side of the balls, and a side groove is formed on the side of the cage. This invention, by setting an annular groove, a screw, and a support, allows the screw to be tightened inside the side groove, causing the outer surface of the screw to press against the outer surface of the support. Since the outer surface of the screw near the ball is tapered, the movement of the screw will cause one end of the support to move into the annular groove, thereby limiting the movement between the outer and inner rings. This allows the support to share the axial load, ultimately improving the load-bearing performance and thus extending the overall service life of the bearing.

[0004] This patent has the effect of improving load-bearing performance. However, when using existing bearings, if a group of balls is damaged, it is usually not possible to replace them individually, but the entire bearing needs to be replaced, which increases the cost of use and maintenance.

[0005] Therefore, we propose a new type of high load-bearing bearing. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in existing bearings, if a set of balls is damaged, it is usually impossible to replace them individually, but the entire bearing needs to be replaced, which increases the cost of use and maintenance.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high load-bearing bearing, comprising a bearing housing, wherein a disassembly assembly is connected inside the bearing housing, the disassembly assembly comprising a first fixing frame, wherein a ball is connected inside the first fixing frame, a second fixing frame is connected to the outer surface of the ball, a screw is inserted into the surface of the second fixing frame, a threaded hole is circumferentially formed on the outer surface of the bearing housing, a housing cover is attached to the outer surface of the bearing housing, a bolt is circumferentially connected to the surface of the housing cover, and a rotating block is connected to the inner wall of the ball.

[0008] Furthermore, the rotating block is rotatably connected to the bearing housing via balls, and the position and size of the bolt match the position and size of the threaded hole.

[0009] Furthermore, the bolt, after penetrating the outer casing, forms a threaded connection with the threaded hole.

[0010] Furthermore, the rear end of the bearing housing is annularly connected to four sets of lubrication assemblies, each lubrication assembly including a lubrication block, and each set of lubrication blocks is connected to a sealing cap on top.

[0011] Furthermore, a pull rod is inserted inside the lubrication block, a spring is sleeved on the surface of the pull rod, and a push plate is connected to the front end of the pull rod.

[0012] Furthermore, the push plate and the spring form an elastic structure.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when a set of balls is damaged and needs to be replaced, the outer cover and the second fixing bracket can be completely removed, and the damaged balls can be replaced individually, which reduces the cost of bearing use and eliminates the need to replace the whole bearing, thus effectively reducing the cost of use.

[0015] 2. In this utility model, after the lubricant is added into the lubrication block, the spring will automatically push the lubricant into the bearing housing, thereby lubricating the balls and improving the service life of the bearing. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1 - Figure 3 As shown, this utility model provides a high load-bearing bearing, including a bearing housing 1. A disassembly assembly 2 is connected internally to the bearing housing 1. The disassembly assembly 2 includes a first fixing frame 201, with a ball bearing 202 connected internally. A second fixing frame 203 is connected to the outer surface of the ball bearing 202. A screw 204 is inserted into the surface of the second fixing frame 203. A threaded hole 208 is annularly formed on the outer surface of the bearing housing 1. A housing cover 206 is attached to the outer surface of the bearing housing 1. A bolt 207 is annularly connected to the surface of the housing cover 206. A rotating block 205 is connected to the inner wall of the ball bearing 202. The rotating block 205 forms a rotatable connection with the bearing housing 1 through the ball bearing 202. The position and size of the bolt 207 match the position and size of the threaded hole 208. The bolt 207 passes through the housing cover 206 and forms a threaded connection with the threaded hole 208.

[0023] The overall effect of Embodiment 1 is as follows: When a certain group of balls 202 becomes damaged and needs to be replaced after prolonged use of the bearing housing 1, all bolts 207 can be removed from the threaded holes 208, and then the outer cover 206 can be removed. At this time, all screws 204 on the second fixing bracket 203 can be removed, and all balls 202 can be removed from the first fixing bracket 201 and inspected one by one. When a damaged ball 202 is found, it can be removed and replaced individually. Then, the remaining balls 202 are placed back into the first fixing bracket 201, and the second fixing bracket 203 is attached to the surface of the first fixing bracket 201 and fixed with screws 204. Finally, the outer cover 206 is attached to the surface of the bearing housing 1 and fixed with bolts 207. This reduces the cost of bearing use, eliminates the need to replace the entire bearing, and effectively reduces operating costs.

[0024] Example 2, as Figure 1 and Figure 3As shown, four sets of lubrication components 3 are connected in a ring at the rear end of the bearing housing 1. Each lubrication component 3 includes a lubrication block 301. A sealing cover 302 is connected to the top of each lubrication block 301. A pull rod 303 is inserted into the inside of the lubrication block 301. A spring 304 is sleeved on the surface of the pull rod 303. A push plate 305 is connected to the front end of the pull rod 303. The push plate 305 and the spring 304 form an elastic structure.

[0025] The effect achieved by the entire embodiment 2 is as follows: When in use, the sealing cover 302 of the lubricating block 301 can be fully opened, and the pull rod 303 can be pulled from the outside. The pull rod 303 drives the push plate 305 to compress the spring 304, increasing the internal space of the lubricating block 301. At this time, lubricant can be injected into the lubricating block 301, and the sealing cover 302 can be installed. The pull rod 303 can be released, so that the spring 304 pushes the push plate 305 with its own elasticity, causing the lubricant inside the lubricating block 301 to be slowly squeezed into the bearing housing 1, thereby achieving the effect of automatic lubrication of the bearing housing 1 and increasing the service life of the bearing.

[0026] Working principle: When a set of balls 202 is damaged and needs to be replaced, the outer cover 206 and the second fixing bracket 203 can be completely removed, and the damaged ball 202 can be replaced individually, which reduces the bearing's operating cost. There is no need to replace the whole bearing, which effectively reduces the operating cost. After adding lubricant into the lubrication block 301, the spring 304 will automatically push the lubricant into the bearing main housing 1 to lubricate the balls 202 and improve the bearing's service life.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
