Background technique
Common internal structure of motor is as shown in Figure 1, shaft length is mainly determined that drive end bearing bracket seam allowance is deep by following factor out
Degree, rear end cap mouth depth, drive end bearing bracket thickness, rear end cap thickness, stator core height, shaft length etc..Screw passes through iron core
Front and rear cover is fixed together, determines that wave pads the shaft length out of one end after the tolerance stack of above-mentioned material.Some motors
Wave pad is eliminated, to control shaft length tolerance, but this structure can reduce bearing life, and increasing bearing noise, (bearing is normal
Certain precompressed is needed when operating).
The structure there are the problem of, the tolerance of 1. different motor components is different, and (this tolerance is that batch production must
Must), these cause different Motor Shaft length differences larger, under regular situation, there is one end shaft tolerance+1mm of wave pad；
2. when pair shaft, no wave pad end generally can only also guarantee that shaft tolerance+0.5mm(is produced in batches)；3. client is to Motor Shaft
When (such as in order to assemble encoder) required precision is higher than above-mentioned tolerance, then it is difficult all to accomplish, batch production yield is low；4. being
Meet requirement of the client to Motor Shaft length, out shaft length overproof motor often can only complete machine do over again, increase production
It is inconsistent also to will cause motor appearance for manufacturing cost；5. the motor having is because structure is special or the factors even nothing such as shaft gear hobbing
Method is done over again, and causing motor, complete machine is scrapped due to shaft is bad.
Therefore solve the problems, such as that this kind is particularly important, this technology is examined in the design and use to motor
Consider and solves the problems, such as.
