Description

Technical Field

[0001] This utility model belongs to the field of motor equipment maintenance, specifically, it relates to a motor bearing disassembly tool. Background Technology

[0002] As a driving device, electric motors are widely used in various industrial production processes, such as water pumps, fans, and conveyor belts. Motor bearings are the main components of motors. During long-term use, motor bearings need to be maintained or replaced regularly. Usually, workers manually disassemble the bearings using tools such as hammers, crowbars, and three-jaw pullers. This method is not easy to disassemble and can easily damage the motor bearings and motor shaft.

[0003] To address the aforementioned issues, patent application number 2017218589151 discloses an auxiliary tool for disassembling high-voltage motor bearings. This tool includes a clamping plate, a hinge plate, and a handle. Two hinge plates are hinged together at their midpoints via a hinge shaft. A handle is fixed to one end of each hinge plate, and a clamping plate is vertically fixed to the other end of each hinge plate. The two clamping plates are arranged parallel to each other. An arc-shaped groove is formed on the end edge of the clamping plate on the same side of both hinge plates, with the center line of the arc-shaped groove parallel to the center line of the hinge shaft. However, this tool fails to solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, a motor bearing remover is provided that can easily disassemble motor bearings, avoid damage to motor bearings and motor shafts, reduce the labor intensity of workers, and is applicable to motor bearings and motor shafts of various sizes and models.

Detailed Implementation

[0021] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0022] Figure 1 This is a schematic diagram of the structure of the motor bearing disassembler in an embodiment of this utility model.

[0023] like Figure 1 As shown, the motor bearing disassembler provided by this utility model includes a disassembler body 10 and an ejector assembly 20 disposed on the disassembler body 10. One end of the disassembler body 10 is provided with a clamp 30. The ejector assembly 20 abuts against the end of the motor shaft 1, and the clamp 30 abuts against the bearing end face of the motor bearing 2 near the motor 3. The ejector assembly 20 facilitates the disassembly of the motor bearing 2, making it convenient for maintenance or replacement of the motor bearing 2. It can avoid damage to the motor shaft 1 and the motor bearing 2 during the disassembly process, and is applicable to motor bearings 2 and motor shaft 1 of various sizes and models. It can reduce the labor intensity of workers, making the motor bearing disassembler provided by this utility model convenient for disassembling the motor bearing 2, avoiding damage to the motor bearing 2 and motor shaft 1, reducing the labor intensity of workers, and applicable to motor bearings 2 and motor shaft 1 of various sizes and models.

[0024] Figure 2 This is a schematic diagram of the disassembler body in an embodiment of this utility model.

[0025] like Figure 2 As shown, the disassembly body 10 has a mounting block 11 at the end away from the clamp 30. The mounting block 11 has a threaded hole 12. The mounting block 11 and the threaded hole 12 are used to install the ejector assembly 20, so that the ejector assembly 20 can abut against the end of the motor shaft 1. The disassembly body 10 is an arc-shaped tube with a semi-circular cross section, which can provide clearance space for the motor shaft during the disassembly of the motor bearing. The clamp 30 has a limiting groove 31, so that the clamp 30 is U-shaped and fits the motor shaft 1. It can be easily clamped on one side of the motor bearing. The clamp 30 abuts against the bearing end face of the motor bearing 1 near the motor 3, so as to facilitate the disassembly of the motor bearing 2.

[0026] Figure 3 This is a schematic diagram of the ejector assembly in an embodiment of this utility model.

[0027] like Figure 3 As shown, the ejector assembly 20 includes a handle 21 and a hand-operated hydraulic cylinder 22. The handle 21 and the hand-operated hydraulic cylinder 22 are connected. The hand-operated hydraulic cylinder 22 is movably connected to the mounting block 23. The hand-operated hydraulic cylinder 22 includes a cylinder body 221 and an ejector rod 222. One end of the ejector rod 222 is telescopically inserted into the cylinder body 221. The cylinder body 221 is provided with an external thread that matches the threaded hole 12, so that the cylinder body 221 is movably inserted into the threaded hole 12 through threaded engagement. The distance between the ejector rod 222 and the clamp 30 can be adjusted by rotating the cylinder body 221. The end of the ejector rod 222 away from the cylinder body 221 abuts against the end of the motor shaft.

[0028] Rotating the handle 21 on the vertical plane of the ejector rod 222 axis causes the cylinder 221 to rotate, thus initially adjusting the distance between the ejector rod 222 and the clamp 30. This facilitates the contact between the end of the ejector rod 222 and the end of the motor shaft 1, and the contact between the clamp 30 and the bearing end face of the motor bearing 1 near the motor 3. This secures the motor bearing remover. Next, the bearing can be removed in two ways: one is by rotating the handle 21 on the vertical plane of the ejector rod 222 axis, causing the cylinder 221 to pass through the threaded hole 12, with the end of the ejector rod 222 continuously pressing against the end of the motor shaft 1, and the clamp 30 at the other end of the remover body 10 applying pressure to the motor bearing 2. One method is to apply a force away from the motor 3 to disassemble the motor bearing 2; another method is to rotate the handle 21 in the axial direction of the ejector rod 222, thereby driving the hand-operated hydraulic cylinder 22 to eject the ejector rod 222. The clamp 30 at the other end of the disassembler body 10 applies a force away from the motor 3 to the motor bearing 2, thereby disassembling the motor bearing 2. Therefore, the motor bearing disassembler provided by this utility model can easily disassemble the motor bearing 2, facilitate the maintenance or replacement of the motor bearing 2, avoid damage to the motor bearing 2 and motor shaft 1, reduce the labor intensity of workers, and is applicable to motor bearings 2 and motor shafts 1 of various sizes and models.

The ejector assembly 20 abuts against the end of the motor shaft 1, and the clamp 30 abuts against the bearing end face of the motor bearing 2 near the motor 3. The ejector assembly 20 allows for easy disassembly of the motor bearing 2, facilitating maintenance or replacement of the motor bearing 2. It avoids damage to the motor shaft 1 and the motor bearing 2 during the disassembly process and is applicable to various sizes and models of motor bearings 2 and motor shaft 1. It reduces the labor intensity of workers, making the motor bearing disassembly tool provided by this utility model convenient for disassembling the motor bearing 2, avoiding damage to the motor bearing 2 and motor shaft 1, reducing the labor intensity of workers, and applicable to various sizes and models of motor bearings 2 and motor shaft 1.
