[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] The utility model provides Figure 1-4 The motor bearing cover structure shown in the figure comprises a disc body 1, a ring seat 2 arranged on one side of the disc body 1, and an oiling component for oiling the motor shaft is arranged on the ring seat 2;

[0031] The oil filling assembly includes an annular cavity 31 opened inside the ring seat 2, an oil absorbing cotton 32 installed inside the cavity 31, an oil filling nozzle 33 arranged on one side of the ring seat 2, and a cover 34 connected to the oil filling nozzle 33;

[0032] The oil-absorbing cotton 32 is set in an X shape to increase the oil output at the connection between the ring seat 2 and the motor shaft;

[0033] Furthermore, a fastening assembly is installed on the disc body 1, which can connect the disc body 1 with the motor end cover.

[0034] In one embodiment, the oil-absorbing cotton 32 is arranged in an X shape, and at least two oil-absorbing cottons 32 are evenly spaced in the cavity 31 , and one end of each of the oil-absorbing cotton 32 close to the inner wall of the ring seat 2 passes through the inner wall of the ring seat 2 and is flush with the inner wall of the ring seat 2 .

[0035] In one embodiment, the oiling nozzle 33 corresponds to one of the oil absorbing cottons 32, so that the staff can observe the state of the oil absorbing cotton 32 when absorbing lubricating oil. The sealing cap 34 and the oiling nozzle 33 are configured to be threadedly connected to facilitate the opening or closing of the sealing cap 34.

[0036] In one embodiment, the fastening assembly includes two annular plates 41 connected to the side walls of the disk body 1, a fastener 42 arranged between the two annular plates 41, and a pressure plate 43 installed at the openings of the two annular plates 41. When the fastener 42 is tightened, the pressure plate 43 is screwed into the annular plate 41 to apply pressure on the fastener 42, so that the fastener 42 is not easy to loosen during use. There are four fasteners 42, which are distributed in an annular array on one side of the disk body 1 to increase the stability of the disk body 1 after installation, and each threaded section of the fastener 42 is set throughout the disk body 1. The pressure plate 43 is set in an annular shape and is threadedly connected to the two annular plates 41. After the pressure plate 43 is fully screwed in, it can contact the end of the fastener 42. A number of grooves 44 are provided on the outer surface of the pressure plate 43, so that the staff can quickly rotate the pressure plate 43.

[0037] In one embodiment, a fixing sleeve 5 is connected to a side of the disc body 1 away from the ring seat 2 for engaging with the motor bearing to facilitate the use of the bearing cover.

[0038] The specific implementation method is as follows: during assembly of the utility model, each fastener 42 is set as a bolt. The staff matches the bolt with the threaded hole on the motor end cover, and then tightens the bolt to install the disc body 1 on the motor end cover. Then, the pressure plate 43 is screwed in between the two annular plates 41 to apply pressure to the fastener 42, i.e., the end of the bolt, to prevent the bolt from loosening due to motor vibration during use, so that the bolt will not fall off, thereby increasing the connection strength between the disc body 1 and the motor end cover;

[0039] Specifically, when in use, the staff injects lubricating oil into the cavity 31 until the lubricating oil fills the entire cavity 31, and tightens the cover 34. The oil-absorbing cotton 32 absorbs the lubricating oil in the cavity 31 and becomes moist. In this way, when the motor shaft rotates, the lubricating oil at the end of the oil-absorbing cotton 32 will be directly applied to the outside of the shaft, and as the shaft rotates continuously, an oil film is formed on the outside of the shaft, reducing the friction between the shaft and the bearing cover, that is, the ring seat 2. The X-shaped oil-absorbing cotton 32 can expand the oil outlet surface, so that the oil supply area between the ring seat 2 and the shaft is large, the oil supply is high, the shaft can be fully lubricated, the oil film is formed quickly, the lubrication effect is good, and the wear between the shaft and the bearing cover is reduced.

[0040] At the same time, the oil-absorbing cotton 32 can also prevent the lubricating oil in the cavity 31 from flowing out at will. While blocking the lubricating oil in the cavity 31, the ring seat 2 completes the task of supplying oil to the motor shaft, and can also absorb the noise generated by the shaft when it rotates, so that the oil-absorbing cotton 32 can be used for multiple purposes and has high practicality.

[0041] This embodiment specifically solves the problem in the prior art that the motor bearing cover is usually connected to the motor end cover by bolts. After connection, the bolts are easy to loosen and the connection strength is not high; and there is often insufficient oil supply at the connection between the motor shaft and the bearing cover, and an oil film cannot be formed between the shaft and the bearing cover, resulting in insufficient lubrication effect, resulting in a short life of the shaft and the bearing cover, which urgently needs to be improved.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
