AI Technical Summary
Technical Problem
When existing electric spindle stators are fixed by interference fit, there are problems such as high assembly precision requirements, difficulty in disassembly, and easy damage.
Method used
The radial engagement of fasteners and pin holes is used to fix the stator, replacing the traditional interference fit. The axial and circumferential fixation of the stator is achieved through the engagement of threaded holes and pin holes.
Benefits of technology
It reduces the reliance on dimensional accuracy in assembly, avoids stator loosening or housing damage, simplifies the disassembly process, and improves maintenance convenience and service life.
