Description

A motor end cover for easy replacement of bearings

technical field

The utility model relates to the field of motors, in particular to a motor end cover which is convenient for replacing bearings.

Background technique

In the maintenance of motors, it is often encountered to replace bearings; the common steps are to remove the end cover of the motor first, take out the rotor of the motor, then replace the bearings, and finally reinstall the rotor and end cover. This method is not only efficient Very low, and for the current permanent magnet motor, it is more inconvenient to disassemble the rotor, and more special tools are needed, and the rotor may be damaged, resulting in more economic losses. For this reason, we have developed a convenient The motor end cover of the bearing is replaced, and the bearing seat is detachably installed on the motor shell, which not only improves the work efficiency, but also reduces the economic loss.

Utility model content

The purpose of the utility model is to provide a motor end cover for easy replacement of bearings in order to overcome the deficiencies of the prior art. By detachably installing the bearing seat on the motor shell, not only the working efficiency is improved, but also the economic loss is reduced.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a motor end cover for easy replacement of bearings, including end covers arranged at both ends of the casing; a detachable bearing seat is arranged inside the end cover; the bearing A bearing is arranged in the seat, and the outer ring of the bearing is respectively positioned by the shaft shoulder of the bearing seat and the end cover.

Preferably, the bearing seat is provided with a plurality of removal holes for easy removal of the bearing.

Preferably, the contact surface between the end cover and the bearing seat is an inclined plane, which facilitates the removal of the bearing seat from the end cover.

Preferably, sealing rings are respectively provided at the joints of the end cover, the casing and the bearing seat, and the bearings are sealed bearings.

Preferably, the bearing seat is fixed in the end cover by a plurality of screws.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The motor end cover for easy replacement of bearings described in the utility model can be quickly repaired or replaced without disassembling the entire motor by detachably installing the bearing seat on the motor casing, which not only improves work efficiency, but also reduces economic loss.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Accompanying drawing 1-2 is the electric motor end cover that is convenient to replace the bearing described in the present utility model, comprises the end cover 2 that is arranged at both ends of casing 1; The described end cover 2 is provided with the bearing seat 4 that is fixed by a plurality of screws 3 , and the contact surface between the end cover 2 and the bearing seat 4 is a slope, which is convenient for taking the bearing seat 4 out of the end cover 2; the bearing seat 4 is provided with an interference fit bearing 5, and the bearing 5 The outer ring is positioned by the bearing seat 4 and the shoulder of the end cover 2 to prevent the bearing 5 from sliding in the bearing seat 4 and affect the transmission accuracy; the bearing seat 4 is provided with a plurality of dismounting holes 41 for easy disassembly of the bearing 5; Sealing rings 6 are respectively provided at the joints of the end cover 2 with the casing 1 and the bearing housing 4 .

When replacing the bearing: first remove the bearing seat 4 from the end cover 2, and then take out the bearing 5 through the dismounting hole 41 on the bearing seat 4 for maintenance or replacement.

Due to the application of the above-mentioned technical solution, the utility model has the following advantages compared with the prior art:

The motor end cover for easy replacement of bearings described in the utility model can be quickly repaired or replaced without disassembling the entire motor by detachably installing the bearing seat on the motor casing, which not only improves work efficiency, but also reduces economic loss.

The above are only specific application examples of the utility model, and do not constitute any limitation to the protection scope of the utility model. All technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the utility model.
