Description

Technical Field

[0001] The utility model relates to the field of interference fit removal and maintenance operations of gears and shafts, in particular to a direct high-speed gear shaft removal device. Background Technique

[0002] The high-speed gear shaft is a commonly used transmission component in industrial production and plays a crucial role in power transmission. Through it, various rotating equipment in industrial production can be connected to achieve power output. However, in industrial production, due to long-term operation or the influence of other impact forces, the high-speed gear will be worn or damaged. Since many high-speed gears are connected to the motor by interference fit, it is time-consuming and laborious to use conventional disassembly during the maintenance process. The disassembly work is difficult and inefficient, which not only affects the work efficiency but also easily damages the equipment during the disassembly process. Therefore, we designed a device that can change the force-bearing part and force-bearing direction of the gear shaft during the operation of installing the gear shaft fixture, ensuring that the gear is evenly stressed and only bears tensile force during the disassembly operation, thus making the disassembly operation simple and efficient. Content of the Utility Model

[0003] The purpose of the utility model is to provide a direct high-speed gear shaft removal device to remove the gear shaft while protecting the motor end cover.

[0004] In order to achieve the above purpose, the utility model is realized by adopting the following technical solutions:

[0005] The utility model provides a direct high-speed gear shaft removal device, including a gear shaft fixture body and a motor end cover protection pad. The gear shaft fixture body and the motor end cover protection pad are arranged coaxially. A through hole is opened at the top of the gear shaft fixture body and penetrates through to the motor end cover protection pad. The gear shaft fixture body includes a left clamp body and a right clamp body. A locking threaded hole is opened on one side of the left clamp body and penetrates through to the right clamp body. A fixture locking bolt for connecting the left clamp body and the right clamp body is arranged in the locking threaded hole. A top threaded hole is opened at the top of each of the left clamp body and the right clamp body, and a gear shaft disassembly jackscrew is respectively arranged on each of the top threaded holes.

[0006] Furthermore, gear shaft positioning bolts are arranged on the sides of both the left clamp body and the right clamp body.

[0007] Furthermore, the end of the gear shaft disassembly jackscrew acts on the motor end cover protection pad.

[0008] Furthermore, the connection surface between the left clamp body and the right clamp body is a concave-convex connection surface.

[0009] Furthermore, there are 2 fixture locking bolts.

[0010] Furthermore, there are 4 gear shaft positioning bolts.

[0011] Advantages of the present utility model: Through the cooperation of the fixture, the motor end cover protection pad, the bolts and the disassembly jackscrew, the gear shaft connected by the interference fit between the high-speed gear of the speed reducer and the motor shaft can be removed. At the same time, the motor end cover protection pad can protect the motor end cover during the disassembly process. The operation is simple, the disassembly efficiency is improved, and thus the disassembly operation can be completed faster. Description of the Drawings
