Description

Technical Field

[0001] This utility model relates to the field of motor bushing technology, specifically to a motor bushing with stable connection. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque, which drives other components to rotate through the motor shaft. The motor shaft is the actuator of the motor drive. In order to avoid damage to the motor shaft, a motor shaft sleeve is needed to protect the motor shaft.

[0003] While motor bushings can protect the motor shaft, the outer wall of the motor shaft is prone to rust after long-term use. Therefore, it is necessary to remove the rust from the motor shaft regularly. Some existing motor bushings are generally integral structures that are directly fitted onto the outside of the motor shaft. If the motor shaft rusts, it is difficult to remove the motor bushing from the motor shaft, making the disassembly of the motor bushing time-consuming and laborious. Therefore, to address the above problems, a motor bushing with a stable connection is proposed. Utility Model Content

If the motor shaft is rusted, the motor bushing is difficult to remove from the motor shaft, making the disassembly of the motor bushing time-consuming and laborious.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The support sleeve is connected to heat-conducting columns. Heat-dissipating sleeves are fixedly connected to the outer sides of each support sleeve. Each heat-dissipating sleeve is fixedly connected to a set of heat-conducting columns. A second slot is provided on the left half of the lower support sleeve and the right half of the upper support sleeve. A second locking block is fixedly connected to the right half of the lower support sleeve and the left half of the upper support sleeve.

A heat-conducting sleeve is provided on the inner side of each support sleeve. A limiting strip and a pair of support blocks are fixedly connected to the left and right halves of the heat-conducting sleeve. Each pair of support blocks is fixedly connected to the limiting strip.

[0007] Preferably, there are two mounting plates, the shape of the first slot matches the shape of the first block, and each mounting plate is bolted to the first block that is fixedly connected to the other mounting plate.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A stable motor bushing includes a mounting plate 1, a support sleeve 6, a heat dissipation sleeve 9, and a heat-conducting sleeve 14. The right half of the lower mounting plate 1 and the left half of the upper mounting plate 1 are each provided with a first slot 2. The right half of the lower mounting plate 1 and the left half of the upper mounting plate 1 are each provided with a pair of through-holes 3. The left half of the lower mounting plate 1 and the right half of the upper mounting plate 1 are each fixedly connected with a first locking block 4, each first locking block 4 having a pair of through-holes 5. The front side of the mounting plate 1 is fixedly connected to the support sleeve 6, which has a set of evenly distributed mounting holes 7. A heat-conducting sleeve 14 is fixedly connected within each mounting hole 7 of the support sleeve 6. Heat dissipation sleeves 9 are fixedly connected to the outer sides of the heat column 8 and the support sleeve 6. The heat dissipation sleeves 9 are fixedly connected to a set of heat-conducting columns 8. The left half of the support sleeve 6 located on the lower side and the right half of the support sleeve 6 located on the upper side are provided with second slots 10. The right half of the support sleeve 6 located on the lower side and the left half of the support sleeve 6 located on the upper side are fixedly connected with second blocks 11. Rubber sleeves 12 are fixedly connected to the outer sides of the second blocks 11. The inner side of the support sleeve 6 is provided with a pair of left and right symmetrically distributed limiting grooves 13. The inner side of the support sleeve 6 is provided with heat-conducting sleeves 14. The left half and the right half of the heat-conducting sleeves 14 are fixedly connected with limiting strips 15 and a pair of support blocks 16. Each pair of support blocks 16 is fixedly connected to the limiting strips 15.

[0025] There are two mounting plates 1. The shape of the first slot 2 matches the shape of the first block 4. Each mounting plate 1 is bolted to the first block 4, which is fixedly connected to the other mounting plate 1. The mounting plates 1 and the first blocks 4 can be fixed by the connecting bolts, so that the two mounting plates 1 are relatively fixed, and thus the two support sleeves 6 are relatively fixed. There are two support sleeves 6 and two heat dissipation sleeves 9. The mounting holes 7 are all cylindrical slots. The side of the heat conduction column 8 away from the heat dissipation sleeve 9 is tightly fitted with the heat conduction sleeve 14. The heat conduction column 8 and the heat dissipation sleeve 9 can make the device have good heat dissipation. The shape of the second slot 10 is... The shape of the limiting groove 13 matches the shape of the rubber sleeve 12, and the rubber sleeve 12 is a "U" shaped sleeve. The shape of the limiting groove 13 matches the shape of the limiting strip 15. The limiting strip 15 and the support block 16 can ensure that the heat-conducting sleeve 14 is in an extended state and that the two heat-conducting sleeves 14 are tightly fitted to the motor shaft. There are two heat-conducting sleeves 14. The front end of the support block 16 located on the front side is aligned with the front end of the heat-conducting sleeve 14, and the rear end of the support block 16 located on the rear side is aligned with the rear end of the heat-conducting sleeve 14. The heat-conducting sleeve 14 can not only ensure heat dissipation, but also fit tightly to the motor shaft, reducing the contact between the motor shaft and the air.

[0026] Workflow: The device consists of two mounting plates 1, two support sleeves 6, two heat dissipation sleeves 9, and two heat-conducting sleeves 14. When using the device, first, attach the two heat-conducting sleeves 14 to the motor shaft. At this time, the upper limiting strip 15 is attached to the lower limiting strip 15, and the upper support block 16 is attached to the lower support block 16. Then, place the two support sleeves 6 over the outer sides of the two heat-conducting sleeves 14, so that the second locking block 11 and the rubber sleeve 12 are engaged in the second locking groove 10. Because the mounting plate 1 and the support... The sleeve 6 is fixedly connected, so the first locking block 4 is also locked into the first locking groove 2. At this time, the limiting strip 15 is locked into the limiting groove 13. The support block 16, together with the heat-conducting sleeve 14 and the limiting strip 15, forms a cylindrical sleeve. The limiting strip 15 and the support block 16 can ensure that the heat-conducting sleeve 14 is in an extended state, so that the two heat-conducting sleeves 14 and the motor shaft are tightly fitted. Then, the connecting bolt is passed through the first connecting hole 3 and the second connecting hole 5, so that the mounting plate 1 and the first locking block 4 are fixed, so that the two mounting plates 1 are relatively fixed, and thus... With the two support sleeves 6 fixed relative to each other, the device can be used normally. The support sleeves 6 are made of metal, which ensures the mechanical strength of the device. The heat-conducting column 8 and the heat dissipation sleeve 9 in the mounting hole 7 have high thermal conductivity, which enables the device to have good heat dissipation. The heat-conducting sleeve 14 is a high thermal conductivity rubber layer, which not only ensures heat dissipation but also fits tightly with the motor shaft, reducing the contact between the motor shaft and the air. The device has high connection stability through the matching first slot 2 and first slot 4, and the matching second slot 10 and rubber sleeve 12. The matching limiting groove 13 and limiting strip 15 can make the heat-conducting sleeve 14 fit tightly with the motor shaft, making the motor shaft less prone to rust. The support sleeve 6 clamps and fixes the elastic heat-conducting sleeve 14, which makes it easy to remove the support sleeve 6 from the motor shaft. Even if the motor rusts, the device can be easily and quickly disassembled and reinstalled, saving time and effort.
