A kind of above-mentioned rotor last item holds fitting device, and the spring is not when compressing, spring shim, spring Total height is more than limited block；The spring in complete compression, spring shim, spring total height be equal to limited block.

A kind of above-mentioned rotor last item holds fitting device, and the spring shim top is horizontal with the first lower module both sides Part connects.

A kind of above-mentioned rotor last item holds fitting device, and spindle nose is inserted into the magnet ring centre bore, and the spindle nose is inserted The end for entering part connects with bearing.

The utility model has the beneficial effects that：

The utility model is simple in structure, easy to operate, actual production is efficient.By the effect of spring and limited block, reach The impact force afforded to buffer shaft, it is small to bearing impact power, prevent bearing and be damaged, and ensures that last item holds the mesh of size qualification 's.It can ensure that ball and raceway do not damage, promote bearing service life, reduce the noise generated when bearing operation.Efficiency, Quality, cost etc. have and obviously improve.

The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing It is bright, to be fully understood from the purpose of this utility model, feature and effect.
