Contact ball bearing.
The three diagonal contact ball bearing, short sleeve and long sleeve are arranged at the multi-diameter shaft of main shaft, wherein, long sleeve position
On the inner ring that the first diagonal contact ball bearing is withstood in the middle of three diagonal contact ball bearings, make axle sleeve ladder and the first diagonal contact
Ball bearing outer ring is held out against, second and third diagonal contact ball bearing（6,13）Between be connected with short sleeve, and be symmetrically installed, make axle
The positioning of set is more accurately fastened, and is difficult stress change, and grinding force is uniformly transferred to master by the 3rd diagonal contact ball bearing
On axle.
Gap is connected between the emery wheel and axle sleeve, and the belt wheel connects motor, emery wheel by belt
During work, by motor by belt transmission to big belt wheel, driving axle sleeve and emery wheel high-speed rotation, completion is repaiied to emery wheel
It is whole.
The beneficial effects of the invention are as follows：
1. the position of main shaft internal lubrication oil is more careful, two couple of ladder axle sleeve or so is lubricated by middle larger oilhole a
Bearing, by a pair of bearings from the small oilhole b of the right and left to different direction lubricating residuals.
2. cause the axially position of axle sleeve more accurate by the ladder in the middle of axle sleeve, so that emery wheel will not
Occur deviation in axially position, improve the precision of finishing.
3. emery wheel is using three pairs of bearings, two pairs adjacent to be symmetrically installed in the symmetrical bearing of long sleeve, makes determining for axle sleeve
The more accurate fastening in position, is difficult stress change.Remaining a pair of bearings can be such that grinding force uniformly transfers to main shaft, will not make master
Axle is produced compared with large deformation because of unbalance stress.
