Description

Technical Field

[0001] The invention relates to a device capable of solving the problem of axial movement. Background Art

[0002] Motor endplay, also known as axial endplay, refers to the inevitable small movement of the motor shaft along the axial direction during operation. The axis direction is the direction of the shaft, and the direction perpendicular to the axis direction is the direction of the cylindrical surface of the shaft.

[0003] The axial movement of the motor will increase the vibration and noise of the motor, damage the equipment and reduce its service life.

[0004] Generally speaking, the reason for motor movement is that the gap between the rotor shaft and the rotor is too large.

[0005] The movement of the motor shaft enlarges the gap between the joints that should not move relative to each other, increases the vibration and noise of the motor, and may cause "bore scraping", thus reducing the service life.

[0006] In its daily production, the company does not have a mature technical solution to solve the axial movement. Summary of the invention

[0007] The present invention aims at the deficiencies in the prior art and provides a device capable of solving the problem of axial movement, which has a simple structure and an ingenious design and can control the axial movement.

[0008] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a device capable of solving axial movement, comprising a rotating shaft, a bearing is arranged on the rotating shaft, an end cover is arranged on the rotating shaft, a bearing socket for installing the bearing is arranged on the end cover, a through hole is arranged in the bearing socket, the end of the rotating shaft can pass through the through hole, an annular groove is arranged on the inner wall of the through hole in the bearing socket, a retaining ring portion is arranged in the annular groove, and the bearing is pressed on the retaining ring portion.

[0009] The retaining ring portion is provided with a clamping end portion, and the clamping end portion is provided with a clamping hole.

[0010] The annular groove is arranged obliquely, and a positioning protrusion is arranged on the annular groove at a position closest to the outer cross section of the end cover.

[0011] An arc-shaped bendable connecting portion is arranged in the middle of the retaining ring portion, and a notch cooperating with the positioning protrusion is arranged on the connecting portion.

[0012] The two ends of the connection part are provided with connecting ends, the connecting ends are fastened with arc-shaped extended threaded rods, the ends of the arc-shaped extended threaded rods are threadedly connected with arc-shaped end rods, and the front end of the arc-shaped end rods is provided with clamping ends.

[0013] A scale is arranged on the upper surface of the arc-shaped extended threaded rod.

[0014] The invention has the characteristics of simple structure, convenient production, ingenious design and capable of controlling axial movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1 To Attachment Figure 4 As shown, a device capable of solving the problem of axial movement includes a rotating shaft 1, a bearing 3 is arranged on the rotating shaft 1, an end cover 2 is arranged on the rotating shaft 1, a bearing socket 21 for mounting the bearing 3 is arranged on the end cover 2, a through hole 20 is arranged in the bearing socket 21, the end of the rotating shaft 1 can pass through the through hole 20, an annular groove 22 is arranged on the inner wall of the through hole 20 in the bearing socket 21, a retaining ring portion 4 is arranged in the annular groove 22, and the bearing 3 is pressed on the retaining ring portion 4.

[0020] The retaining ring portion 4 is provided with a clamping end portion 41 , and the clamping end portion 41 is provided with a clamping hole 411 .

[0021] The annular groove 22 is arranged obliquely, and a positioning protrusion 221 is arranged on the annular groove 2 at a position closest to the outer cross section of the end cover 2 .

[0022] The retaining ring portion 4 is provided with an arc-shaped bendable connecting portion 40 in the middle thereof, and the connecting portion 40 is provided with a notch 402 cooperating with the positioning protrusion 221 .

[0023] The connecting portion 40 is provided with connecting ends 401 at both ends, and the connecting ends 401 are fastened with arc-shaped extended threaded rods 43 . The ends of the arc-shaped extended threaded rods 43 are threadedly connected with arc-shaped end rods 42 . The front end of the arc-shaped end rods 42 is provided with clamping ends 41 .

[0024] A scale 431 is disposed on the upper surface of the arc-shaped extended threaded rod 43 .

[0025] The device utilizes an adjustable retaining ring portion 4 in conjunction with an obliquely disposed annular groove 22, so that the clearance can be adjusted, thereby avoiding axial movement.

[0026] The adjustable retaining ring portion 4 includes a central connecting portion 40, an arc-shaped extended threaded rod 43 extending outwardly from both ends of the connecting portion 40, and an arc-shaped end rod 42 connected to the ends of the arc-shaped extended threaded rod 43. The arc-shaped end rod 42 and the arc-shaped extended threaded rod 43 are connected by threads, so the connection depth between the two can be adjusted by simply rotating. Then, a scale 431 is provided on the upper surface of the arc-shaped extended threaded rod 43, through which an accurate reading can be obtained.

[0027] The annular groove 22 is arranged obliquely, and a positioning protrusion 221 is arranged on the annular groove 22 at a position closest to the outer end surface of the end cover 2 , and the connecting portion 40 is arranged there and has a notch 402 matching the positioning protrusion 221 .

[0028] When the arc-shaped end rod 42 is further outward, that is, the reading on the scale 431 is larger, it means that the connection between the motor shaft and the end cover 2 is more compact; when the arc-shaped end rod 42 is further inward, that is, the reading on the scale 431 is smaller, it means that the connection between the motor shaft and the end cover 2 is looser.

[0029] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
