Description
Technical field
The utility model relates to a kind of for the concentric locking spline housing of three axles connection, belong to automobile power assembly
Gear arrangement.
Background technology
Three axles of existing most of gearbox heart are coupled, locking, use spline, hot jacket or nut structure,
The connection anti-loose structure opposed configuration of this three axle is complicated, and utility model is poor, and urgent need will be improved.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art is present, and it is simpler tight to provide a kind of structure
Gather, security is higher with reliability, the stronger three concentric axles that are used for of practicality are coupled locking spline housing.
The purpose of this utility model is completed by following technical solution, a kind of to be coupled anti-for three concentric axles
Loose spline housing, it includes abutting and covering by convex shoulder in the hollow shaft that an one end is provided with alternately breach tooth, the hollow shaft
It is equipped with the driven axle that the adjacent gear in one end is inserted in a gear, the opposite side hollow shaft of the gear, the axle of the hollow shaft
Into through hole from an alternately piece elongated small axle of breach tooth one end insertion is provided with, the front end of small axle insertion is provided with outer spiral shell
Line, and be engaged by the external screw thread with the internal thread set in the axially extending bore of driven axle, effectively spun, small axle
Rear end exposes to hollow shaft and exposed end portion is provided with the connection end with spline, and the connection end is configured with an inner wrap strip
The spline housing of spline, outer ring with alternately gap slot, and spline of the inner ring internal spline of spline housing with being connected on end is mutually tied
Close, the outer ring alternating gap slot of spline housing is combined with the alternating breach tooth in hollow shaft.
As preferred：Described small axle connection end is upper to be provided with annular groove on the outside of spline, and passes through a snap ring card
Enter spline housing to be fixed in annular groove the connection end of small axle；The convex shoulder opposite side shaft end of the hollow shaft is configured with one will
Spline housing contains the axle sleeve in it with hollow shaft shaft end.
The utility model is by the way that small axle is put into hollow shaft, by the cooperation with driven axle internal and external screw thread, reaches three axles
The purpose of fastening, spline housing coordinated by internal spline with small axle external splines, replace breach by replace breach tooth and hollow shaft
Groove coordinates, then spline housing is fixed on small axle with snap ring, is finally reached three axles and is coupled locking effect.
The utility model has structure simpler compact, the features such as security and reliability are higher.
