Description

Technical Field

[0001] The utility model relates to the technical field of engineering plastic retainers, in particular to a high-strength and wear-resistant engineering plastic retainer structure. Background Art

[0002] An engineering plastic cage is a plastic component used in bearings. Its main function is to support and maintain the normal working state of the rolling bearing. The engineering plastic cage can support the rolling bearing and help it operate normally. During the operation of railway freight cars, the rolling bearing needs to withstand large loads and vibrations. The engineering plastic cage can help the rolling bearing distribute the load and enhance its load-bearing capacity.

[0003] Common engineering plastic cage structures are relatively simple. During use, the roller rubs against the cage for a long time, causing wear on the cage, thereby reducing the service life of the cage and making it less practical. Therefore, we propose a high-strength and wear-resistant engineering plastic cage structure. Utility Model Content

[0004] The purpose of the present utility model is to solve the shortcomings of the prior art. The common engineering plastic cage has a relatively simple structure. During use, the roller rubs against the cage for a long time, which will cause wear to the cage, thereby reducing the service life of the cage and making it less practical.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-strength, wear-resistant engineering plastic retainer structure comprises a roller, wherein retaining rings are symmetrically arranged at the top and bottom of the roller, and the rollers are provided in plurality and are equidistantly mounted between two retaining rings.

[0007] The inner side of the retaining ring is provided with a plurality of square grooves around the periphery, and the inner side of the square groove is provided with a built-in groove near the outer side. A clamping block is rotatably connected to the inner side of the clamping block, and a partition is welded to the inner side of the partition, and an insertion rod is welded to the bottom of the partition.

[0008] As a preferred solution of the present invention, slots are symmetrically provided at the top and bottom of the roller, and the insertion rods are adapted to the slots.

[0009] The technical effect of adopting the above further solution is: the installation of the roller is facilitated by the adaptation of the slot and the insertion rod, and the contact area between the roller and the retaining ring can also be reduced, thereby reducing the wear on the retaining ring and increasing the service life.

[0010] As a preferred solution of the present invention, the roller is made of an alloy material with a smooth surface, and the diameter of the roller is slightly smaller than the width of the square groove.

[0011] The technical effect of adopting the above further solution is: by designing the roller diameter to be slightly smaller than the square groove width, the contact frequency between the roller and the square groove when the device is in use can be reduced, thereby reducing wear.

[0012] As a preferred solution of the present invention, the retaining ring is made of ultra-high molecular weight polyethylene.

[0013] The technical effect of adopting the above further solution is: the wear resistance of the high molecular weight polyethylene material is extremely high, even exceeding that of some metal materials. The ultra-high molecular weight polyethylene material can improve the wear resistance of the retaining ring and further increase the service life of the retaining ring.

[0014] As a preferred solution of the present invention, the block, the partition and the insertion rod are all made of alloy material, and the partition is in the shape of a disc.

[0015] The technical effect of adopting the above-mentioned further scheme is: the roller can be fixed and limited better through the metal material of the block, partition and plug rod. At the same time, the metal material also has high wear resistance, which improves the overall service life. The top and bottom of the roller can be limited by the partition to prevent it from sliding up and down during use, thereby improving the stability of use.

[0016] As a preferred solution of the present invention, the top of the retaining ring near the top is penetrated by the bottom and is surrounded by several threaded rods, and the top of the retaining ring near the bottom is provided with a threaded opening corresponding to the threaded rod, and the threaded rod is threadedly connected to the threaded opening.

[0017] The technical effect of adopting the above further solution is: by rotating the threaded rod, the retaining ring near the top can be penetrated and screwed into the threaded opening, thereby fixing the two retaining rings and improving installation convenience.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] In the utility model, through the design of the roller and the retaining ring, the roller can be fixed and limited by the clamping block, partition and insertion rod during use, reducing the contact frequency between it and the retaining ring, achieving the effect of reducing wear, greatly improving the overall service life of the equipment, and effectively improving practicality.

[0028] Example 1

[0029] like Figure 1-3As shown, the utility model provides a technical solution: a high-strength wear-resistant engineering plastic retaining frame structure, including a roller 1, a retaining ring 2 is symmetrically arranged on the top and bottom of the roller 1, a plurality of rollers 1 are provided, which are equidistantly arranged around the two retaining rings 2, a plurality of square grooves 201 are opened around the inner side of the retaining ring 2 near the outer periphery, a built-in groove 202 is opened inside the square groove 201 near the outer side, a clamping block 203 is rotatably connected to the inside of the built-in groove 202, a partition 204 is welded to the inner side of the clamping block 203, and an insert rod 205 is welded to the bottom of the partition 204.

[0030] Example 2

[0031] like Figure 1-3 As shown, slots 101 are symmetrically provided at the top and bottom of the roller 1, and the insertion rod 205 is adapted to the slot 101. The adaptation of the slot 101 and the insertion rod 205 facilitates the installation of the roller 1, and can also reduce the contact area between the roller 1 and the retaining ring 2, reduce the wear on the retaining ring 2, and improve the service life. The roller 1 is made of an alloy material with a smooth surface, and the diameter of the roller 1 is slightly smaller than the width of the square groove 201. By designing that the diameter of the roller 1 is slightly smaller than the width of the square groove 201, the contact frequency between the roller 1 and the square groove 201 can be reduced when the equipment is in use, thereby reducing wear. The retaining ring 2 is made of ultra-high molecular weight polyethylene. The wear resistance of the high molecular weight polyethylene material is extremely high, even exceeding that of some metal materials. The ultra-high molecular weight polyethylene material can improve the wear resistance of the retaining ring 2, further improving the service life of the retaining ring 2. The block 203 and the partition 204 The top and bottom of the roller 1 can be limited by the partition 204 to prevent it from sliding up and down during use, thereby improving the stability of use. The top of the retaining ring 2 near the top is surrounded by a number of threaded rods 206 through the bottom, and the top of the retaining ring 2 near the bottom is provided with a threaded opening 207 corresponding to the threaded rod 206. The threaded rod 206 is threadedly connected to the threaded opening 207. By rotating the threaded rod 206, it can penetrate the retaining ring 2 near the top and screw into the inside of the threaded opening 207, thereby fixing the two retaining rings 2 and improving the convenience of installation.

[0032] The working process of the present invention is as follows: when installing and using a high-strength wear-resistant engineering plastic retaining frame structure, first, the slot 101 at the bottom of the roller 1 is sequentially sleeved on the outer periphery of the insertion rod 205 on the retaining frame near the bottom, and the other retaining ring 2 is moved to the top of the roller 1, and the insertion rod 205 at its bottom is inserted into the slot 101 opened near the top of the roller 1 to complete the initial fixation of the roller 1, and then the threaded rod 206 is rotated to pass through the retaining frame near the top, and spirally immersed in the threaded opening 207, and the two retaining rings 2 are connected and fixed to complete the entire installation process. During use, the roller 1 can be fixed and limited by the block 203, partition 204 and insertion rod 205, thereby reducing the contact frequency between the roller 1 and the retaining ring 2, thereby achieving the effect of reducing wear, greatly improving the overall service life of the equipment, and effectively improving practicality.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
