Further, spline locating slot is provided with and communicated on the right side of the blind hole, the internal diameter of the blind hole is more than spline chamber
The internal diameter of body and spline locating slot.
Further, annular groove is provided with and communicated on the left of the spline cavity, it is left that the annular groove internal diameter is more than annular groove
The line shaft of side inserts in the hole the internal diameter of diameter and spline cavity.
Further, the oil filler point through left inside spline ontology is provided with and communicated on the spline locating slot.
Further, it is fixedly installed bearing guide rod on the right side of the right external splines；Setting on the left of the bearing guide rod
There is screens slot.
Further, the left inside spline is identical as the spline tooth number of right external splines.
（Three）Advantageous effect
The utility model its have the advantages that：
The splined shaft of a kind of splined shaft of blind hole inner spline of the utility model, the structure is additionally arranged oiling in itself ontology
Hole, except be additionally arranged installation reserved location blind hole, improve the compactness and degree of lubrication between splined shaft and corresponding mechanism, the knot
The left and right link position of structure splined shaft is respectively arranged with annular groove, screens slot, increases connective stability, to greatly increase spline
The service life of axis.
Description of the drawings
