Description

Technical Field

[0001] This utility model relates to the technical field of motors, and specifically to a motor bearing fixing structure that is easy to disassemble and assemble. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In circuits, an electric motor is represented by the letter M (D in the old standard). Its main function is to generate driving torque and serve as a power source for electrical appliances or various machines. Its main function is to convert mechanical energy into electrical energy. When manufacturing an electric motor, it is necessary to assemble components such as the housing, end cover, rotor, shaft, and bearings.

[0003] However, traditional bearing fixing methods often employ shaft shoulder positioning with nut locking, or use mechanical structures such as snap rings and set screws to achieve axial fixation. However, these structures have significant drawbacks in practical applications: firstly, installation requires specialized tools for cumbersome tightening of the nut or snap ring, and disassembly requires reverse operation and may scratch the shaft surface, resulting in low maintenance efficiency. Therefore, those skilled in the art have provided a motor bearing fixing structure that facilitates disassembly and assembly to solve the problems mentioned in the background art. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A motor bearing fixing structure that is easy to assemble and disassemble includes a base, the two sides of which are fixed by bolts, a mounting hole is provided in the middle of the base, a bearing body is fixedly installed in the mounting hole, a fixing groove is provided on all four sides of the inner side of the bearing body, a connecting block is fixedly installed in the fixing groove, and a fixing mechanism is fixedly installed on the inner side of the connecting block.

[0006] Preferably, the fixing mechanism includes a fixing ring, the outer side of which is fixedly connected to the inner side of the four connecting blocks.

[0007] Preferably, driving rings are fixedly installed at both ends of the fixed ring, the driving rings are frustum-shaped, and driving grooves are formed around the circumference of the driving rings.

[0008] Preferably, the drive ring is made of an elastic material, the elastic force of the drive ring is set in a direction that tends towards the outside of the drive ring, and the outside of the drive ring is provided with threads.

[0009] Preferably, a rotating ring is threaded onto the outer side of the drive ring, and the rotating ring is frustum-shaped.

[0010] Preferably, clamping rings are fixedly installed around one end of the drive ring, and an elastic pad is fixedly installed on the inner side of the clamping rings.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The designed fixing mechanism facilitates the installation of the bearing body onto the motor shaft. By driving two rotating rings, the threads of these rings rotate, causing one side of the drive ring to elastically move towards the drive groove. This, in turn, drives the clamping rings to clamp the motor shaft, resulting in the clamping rings at both ends of the fixing ring holding the two sides of the motor shaft, thus fixing the bearing body to the motor shaft. For disassembly, the rotating rings can be driven in the opposite direction, causing the drive ring to reset due to its elastic potential energy, facilitating the removal of the fixing mechanism from the motor shaft. This convenient and quick fixation of the bearing body to the motor shaft improves work efficiency. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to embodiments:

[0018] This utility model discloses a motor bearing fixing structure that is easy to assemble and disassemble. (Refer to...) Figure 1-3 It includes a base 1, which is fixed on both sides by bolts. A mounting hole 2 is provided in the middle of the base 1. A bearing body 3 is fixedly installed in the mounting hole 2. Fixing grooves 4 are provided on all four sides of the inner side of the bearing body 3. A connecting block 5 is fixedly installed in the fixing groove 4. A fixing mechanism is fixedly installed on the inner side of the connecting block 5.

[0019] By adopting the above technical solution, this utility model, through its fixed mechanism, facilitates the installation of the bearing body 3 on the motor shaft. The two rotating rings 9 are driven, and their threads rotate, causing one side of the drive ring 7 to elastically move towards the drive groove 8. This drives the clamping ring 10 to clamp the elastic pad 11, thus holding the motor shaft in place. Consequently, the clamping rings 10 at both ends of the fixed ring 6 clamp the two sides of the motor shaft, fixing the bearing body 3 to the motor shaft. During disassembly, the rotating rings 9 are driven in the opposite direction, causing the drive ring 7 to reset due to elastic potential energy, facilitating the removal of the fixed mechanism from the motor shaft. This allows for quick and easy fixing of the bearing body 3 to the motor shaft, thereby improving work efficiency.

[0020] Reference Figure 1-3 The fixing mechanism includes a fixing ring 6, the outer side of which is fixedly connected to the inner side of four connecting blocks 5. Drive rings 7 are fixedly installed at both ends of the fixing ring 6. The drive rings 7 are frustoconical in shape and have drive grooves 8 around their circumference. The drive rings 7 are made of elastic material, with the elastic force directed outwards, and the outer side of the drive rings 7 is threaded.

[0021] By adopting the above technical solution, one side of the drive ring 7 can move elastically toward the drive groove 8, thereby driving the clamping ring 10 to drive the elastic pad 11 to clamp the motor shaft, so that the clamping rings 10 at both ends of the fixed ring 6 clamp the two sides of the motor shaft, and the bearing body 3 is relatively fixedly connected to the motor shaft.

[0022] Reference Figure 1-3 A rotating ring 9 is threaded onto the outer side of the drive ring 7. The rotating ring 9 is frustoconical in shape. Clamping rings 10 are fixedly installed around one end of the drive ring 7, and elastic pads 11 are fixedly installed on the inner side of the clamping rings 10.

[0023] By adopting the above technical solution, when the bearing body 3 is installed on the motor shaft, the two rotating rings 9 can be driven to rotate. The threaded rotation of the two rotating rings 9 can drive one side of the drive ring 7 to move elastically toward the drive groove 8, thereby driving the clamping ring 10 to drive the elastic pad 11 to clamp the motor shaft. When disassembling, the rotating rings 9 can be driven in the opposite direction, so that the drive ring 7 can be reset due to the drive of elastic potential energy, thereby facilitating the removal of the fixing mechanism from the motor shaft.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
