Description

Motor bearing mounting structure

Technical Field

The utility model relates to the technical field of bearing installation, in particular to a motor bearing installation structure.

Background

In many fields of modern industrial production, the motor is used as a core power device, and the running stability and reliability of the motor are important. The bearing is used as a key supporting component of the motor, and directly relates to whether the motor can smoothly and efficiently run. However, the conventional motor bearing mounting structure has a plurality of limitations in practical application, and is difficult to adapt to increasingly complex industrial requirements.

On one hand, in the matching installation link of the bearing and the shaft lever, the difficult problem of precision matching is often faced. Due to the limitations of the machining process, it is difficult to achieve the desired high precision consistency of the actual dimensions of the shaft and bearing components. Many conventional mounting structures lack an effective adaptive adjustment mechanism that can easily cause wobble problems of the bearing on the shaft when there is a slight dimensional misalignment between the shaft and the bearing member. The shaking can generate extra noise to interfere the normal running environment of the motor, further aggravate the abrasion of the bearing and the shaft lever, greatly shorten the service life of the bearing and the shaft lever, increase the maintenance cost and the downtime of the equipment and seriously influence the production continuity.

On the other hand, the conventional motor bearing mounting mode is poor in universality. With the diversification of motor application scenes, the market demand for bearings with different specifications and sizes is growing. However, most of the existing mounting structures are designed for bearings with specific dimensions, and are difficult to flexibly adapt to various dimensional changes. When the bearings of different types need to be replaced, the whole installation structure is often required to be readjusted or even modified, so that a great deal of labor, material resources and time cost are undoubtedly consumed, the production efficiency is reduced, and the rapid deployment and application of the motor under different working conditions are limited.

In addition, the convenience of the conventional mounting structure in the mounting process is also to be improved. Complicated installation steps, complicated positioning operation and high dependence on professional installation tools make the installation period long and have extremely high requirements on skills of operators. Once improperly operated, it is also prone to damage to the bearings or shafts, further increasing production costs.

It is therefore necessary to provide an electrode bearing mounting structure which is easy to mount and highly adaptable to solve the above-mentioned problems.
