Structure does not change axial length, and positioning snap ring is caught in axial trough, the axially position of realization shaft end part, dismounting and exchange easy to repair,
The problems in background technology can effectively be solved.
In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：
The utility model provides a kind of shaft end part axial location structure, including bucket wheel wheel shaft, spline housing, bucket wheel wheel it is firm,
Boring cover, positioning snap ring and support positioning sleeve, the firm top of the bucket wheel wheel are equipped with spline housing, and the spline housing is set in the bucket
The outside of wheel shaft is taken turns, one end of the bucket wheel wheel shaft is equipped with boring cover, the side positioning snap ring connection of the boring cover, the positioning card
The both ends of ring are connect with support positioning sleeve.
As a kind of optimal technical scheme of the utility model, the positioning snap ring passes through screw with support positioning sleeve both ends
It is fixed.
As a kind of optimal technical scheme of the utility model, the side of the support positioning sleeve is also firm with the bucket wheel wheel
Connection.
As a kind of optimal technical scheme of the utility model, one end of screw passes through the boring cover and blocks with the positioning
Ring is fixed.
The advantageous effect that the utility model is reached is：A kind of shaft end part axial location structure, does not change axial length, will determine
Position snap ring is caught in axial trough, realizes the axially position of shaft end part, dismounting and exchange easy to repair.
