Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sliding bearings, in particular to a magnetic center adjustment structure for a sliding bearing type motor. Background Technique
[0002] Bearings are usually arranged inside the motor to support the rotor and reduce the rotation resistance of the rotor. The bearings used are divided into rolling bearings and sliding bearings. Compared with rolling bearings, sliding bearings generally have better load-bearing capacity and are suitable for medium and low-speed operation of motors. Moreover, sliding bearings can allow axial displacement of the motor, so it is convenient for the electromagnetic force to pull the rotor back to the magnetic center line to achieve the adjustment effect.
[0003] After the existing motor sliding bearings are used for a period of time, they are prone to damage due to factors such as fatigue, uneven lubrication, and high temperature. The existing disassembly method is mainly to remove the two bolts and then remove the shaft cover, thus ending the limit on the bearing bush for easy replacement. This operation is relatively cumbersome. The two bolts need to be rotated many times to be completely removed from the shaft seat, and also need to be rotated many times to be tightened during installation, which is time-consuming and laborious. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a magnetic center adjustment structure for a sliding bearing type motor to solve the technical problem of time-consuming and laborious disassembly and assembly operations.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A magnetic center adjustment structure for a sliding bearing type motor, including a shaft seat and a shaft cover. A limit frame is placed on one side of the top of the shaft seat, and a bolt passes through one side of the top of the limit frame. Friction plates are arranged on both the top and bottom of the limit frame. A rotation stop plate is fixed on one side of the shaft seat, and a limit groove is opened on one side of the top of the shaft cover.
[0006] By adopting the above technical solution, during disassembly, only need to loosen the bolt without completely removing it, which is time-saving and labor-saving. After loosening the bolt, slide the limit frame upward and then rotate it counterclockwise by half a turn, and then the limit frame can be removed, and at the same time, the limit on the shaft cover is ended; during installation, put the limit frame on the outside of the bolt, then rotate the limit frame clockwise by half a turn and then let the limit frame move downward by gravity, so that one side of the limit frame enters the limit groove to limit the shaft cover. Then only need to tighten the bolt clockwise. At the same time, the limit frame abuts against the rotation stop plate to prevent the limit frame from continuing to rotate clockwise, and subsequently, the friction force is increased through the friction plates to avoid the phenomenon of deflection of the bolt and the limit frame.
[0007] Further, the cross-section of the limit frame is in the shape of "Z", and a groove is opened on the back of the limit frame.
[0008] By adopting the above technical solution, the cross-section of the limit frame is Z-shaped, enabling one side of the top of the limit frame to be limited by the bolt, thereby limiting the shaft cover through the other side of the top of the limit frame and reducing the use of bolts.
[0009] Furthermore, the outer surface of the limit frame abuts against the anti-rotation plate, and one side of the limit frame abuts against the shaft cover.
[0010] By adopting the above technical solution, the staff sleeved the limit frame outside the bolt. Then the staff rotated the limit frame clockwise by half a turn and then let the limit frame move downward by gravity, so that one side of the limit frame entered the limit groove to limit the shaft cover. After that, the staff only needed to tighten the bolt clockwise, and at the same time, the limit frame abutted against the anti-rotation plate to prevent the limit frame from continuing to rotate clockwise.
[0011] Furthermore, the friction plate at the top of the limit frame contacts the bolt, and the friction plate at the bottom of the limit frame contacts the shaft seat.
[0012] By adopting the above technical solution, after tightening the bolt, the friction force is increased through the friction plate to prevent the bolt and the limit frame from deflecting.
[0013] Furthermore, there are two bolts, anti-rotation plates, limit frames and limit grooves, and the two anti-rotation plates and limit frames are arranged diagonally and mirror-symmetrically.
[0014] By adopting the above technical solution, the bolts, anti-rotation plates, limit frames and limit grooves are provided to limit both sides of the top of the shaft cover, thereby effectively preventing the shaft cover from falling off.
[0015] Furthermore, the shaft cover is connected to the top of the shaft seat. Bearing bushes are connected inside both the shaft seat and the shaft cover, and an oil plug penetrates through the top of the shaft cover.
[0016] By adopting the above technical solution, the rotor of the motor is located inside the inner ring of the bearing bush. The bearing bush supports the rotor and prevents friction between the rotor and the shaft seat and the shaft cover. To increase lubricity, the staff removes the oil plug and injects lubricating oil into the bearing bush using a syringe.
[0017] Furthermore, the shaft cover is detachably connected to the shaft seat.
[0018] By adopting the above technical solution, during disassembly, the staff loosens the bolt. After loosening the bolt, the staff slides the limit frame upward and then rotates it counterclockwise by half a turn. Then the staff can remove the limit frame and at the same time end the limitation of the shaft cover.
[0019] Furthermore, three oil grooves are respectively formed inside the bearing bush, and the three oil grooves are equidistantly distributed. A communication groove is provided between the three oil grooves.
[0020] By adopting the above technical solution, the oil storage capacity is increased through the cooperation of three oil grooves and the communication groove, and it is convenient for the rotor to contact the lubricating oil, so as to achieve a better lubricating oil effect.
[0021] To sum up, the main beneficial effects of the present utility model are as follows:
[0022] With the settings of bolts, anti-rotation plates, limit frames, friction plates and limit grooves in the present utility model, during disassembly, only need to loosen the bolts without completely removing them, which is time-saving and labor-saving. After loosening the bolts, slide the limit frame upward and then rotate it counterclockwise by half a turn, and then the limit frame can be removed, and at the same time, the limitation of the shaft cover ends; during installation, put the limit frame on the outside of the bolt, then rotate the limit frame clockwise by half a turn and then let the limit frame move downward by gravity, so that one side of the limit frame enters the limit groove to limit the shaft cover. After that, only need to tighten the bolt clockwise, and at the same time, the limit frame abuts against the anti-rotation plate to prevent the limit frame from continuing to rotate clockwise, and subsequently, the friction force is increased through the friction plate to avoid the phenomenon of deflection of the bolt and the limit frame; the disassembly and assembly operations are simple and fast, time-saving and labor-saving.

A groove is provided on the back of the limit frame 7. A bolt 5 penetrates through one side of the top of the limit frame 7. The staff loosens the bolt 5. After loosening the bolt 5, the staff slides the limit frame 7 upward and then rotates it counterclockwise by half a turn. Then, the staff can remove the limit frame 7 and at the same time end the limitation of the shaft cover 2. Friction plates 8 are provided on both the top and bottom of the limit frame 7. The friction plate 8 on the top of the limit frame 7 is in contact with the bolt 5, and the friction plate 8 on the bottom of the limit frame 7 is in contact with the shaft seat 1. The friction force is increased through the friction plates 8 to avoid the phenomenon of deflection of the bolt 5 and the limit frame 7. A rotation stop plate 6 is fixed on one side of the shaft seat 1. The outer surface of the limit frame 7 abuts against the rotation stop plate 6. The staff tightly screws the bolt 5 clockwise. At the same time, the limit frame 7 abuts against the rotation stop plate 6 to prevent the limit frame 7 from continuing to rotate clockwise. There are two bolts 5, rotation stop plates 6, limit frames 7 and limit grooves 9. The two rotation stop plates 6 and limit frames 7 are arranged diagonally and mirror-symmetrically. A limit groove 9 is provided on one side of the top of the shaft cover 2. One side of the limit frame 7 abuts against the shaft cover 2, and one side of the limit frame 7 enters the limit groove 9 to limit the shaft cover 2.
[0032] Referring to Figures 1 - 4 , in the above embodiment, the shaft cover 2 is connected to the top of the shaft seat 1. Bearing bushes 3 are connected inside both the shaft seat 1 and the shaft cover 2. The rotor of the motor is located inside the inner ring of the bearing bush 3.

An oil plug 4 penetrates through the top of the shaft cover 2 to increase lubricity. The staff removes the oil plug 4 and uses a syringe to inject lubricating oil into the bearing bush 3.
[0033] Embodiment 2:
[0034] On the basis of the above Embodiment 1, in order to increase the lubrication effect, the following settings are now made.
[0035] Referring to Figure 1 , Figure 2 and Figure 4 , in the above embodiment, three oil grooves 10 are respectively provided inside the bearing bush 3.

After that, the staff only needs to tighten the bolt 5 clockwise. At the same time, the limit frame 7 abuts against the anti-rotation plate 6 to prevent the limit frame 7 from continuing to rotate clockwise, and subsequently, the friction plate 8 is used to increase the friction force to prevent the bolt 5 and the limit frame 7 from deflecting.
