Description

Technical Field

[0001] This utility model relates to the field of bearing installation technology, specifically a motor bearing installation structure. Background Technology

[0002] In many areas of modern industrial production, electric motors, as core power equipment, are crucial for their operational stability and reliability. Bearings, as key supporting components of electric motors, directly affect their smooth and efficient operation. However, traditional motor bearing mounting structures have many limitations in practical applications and are difficult to adapt to increasingly complex industrial demands.

[0003] On the one hand, the installation process of bearings and shafts often presents challenges in achieving precise matching. Due to limitations in manufacturing processes, it is difficult to achieve ideal high-precision consistency in the actual dimensions of the shaft and bearing components. Many traditional installation structures lack effective self-adjusting mechanisms, and even slight dimensional deviations between the shaft and bearing components can easily lead to bearing wobble on the shaft. This wobble not only generates additional noise and interferes with the normal operation of the motor, but also accelerates the wear of the bearings and shaft, significantly shortening their service life, increasing equipment maintenance costs and downtime, and seriously affecting the continuity of production.

[0004] On the other hand, traditional motor bearing mounting methods have poor versatility. With the diversification of motor applications, the market demand for bearings of different specifications and sizes is increasing. However, existing mounting structures are mostly designed for bearings of specific sizes, making it difficult to flexibly adapt to various size variations. When it is necessary to replace different bearing models, the entire mounting structure often needs to be readjusted or even modified. This undoubtedly consumes a lot of manpower, material resources, and time, reduces production efficiency, and limits the rapid deployment and application of motors under different operating conditions.

[0005] Furthermore, the ease of installation using traditional mounting structures needs improvement. The complex installation steps, cumbersome positioning operations, and heavy reliance on specialized installation tools result in lengthy installation cycles and demand extremely high skill levels from operators. Improper operation can also easily damage bearings or shafts, further increasing production costs.

[0006] Therefore, it is necessary to provide an electrode bearing mounting structure that is easy to install and highly adaptable to solve the above problems. Utility Model Content

[0011] A lifting beam is provided in the groove, with both ends of the lifting beam extending into two end slots respectively. Clamping members are slidably provided in both ejection slots, and the two clamping members are fixedly connected to both ends of the lifting beam respectively.
