AI Technical Summary
Technical Problem
The rotor bearings and bearing housings of existing low-speed, high-load motors are difficult to separate easily, which affects maintenance efficiency.
Method used
A deformation groove is made on the inner circumferential wall of the bearing bracket on the front end cover of the motor. An arc-shaped clamp is fitted and the bearing bracket is expanded by abutment blocks and limiting bolts, which facilitates the disassembly and installation of the rotor bearing.
Benefits of technology
It enables convenient separation and stable connection between the rotor bearing and the bearing housing, improving maintenance efficiency and operational stability.

Abstract
The utility model discloses motor front end cover relates to motor technical field, and its technical scheme main points are: including end cover body, be equipped with bearing bracket on end cover body, open deformation groove on bearing bracket, the arc hoop is equipped with on bearing bracket, open deformation mouth on arc hoop, be equipped with the resistance block on end cover body, be equipped with the limit bolt on end cover body. When needing to dismount rotor bearing and overhaul, first remove the limit bolt to the resistance block's limit, make resistance block no longer resist the arc hoop, owing to the opening of deformation mouth, make the inner diameter of arc hoop can be big, thereby make arc hoop no longer resist the bearing bracket closely, and owing to the deformation groove of the inner peripheral wall on bearing bracket and open make the inner diameter of bearing bracket can expand a certain amount, facilitate rotor bearing to be taken out from bearing bracket, compared with the prior art need to take out rotor bearing from bearing bracket through knocking, above-mentioned setting make rotor bearing and bearing rack's separation more convenient.
