Abstract
The utility model relates to a spline shaft belongs to auto -parts technical field. It comprises the spline shaft body, and the interval form is provided with first spline, second spline and third spline on the spline shaft body, is provided with the constant head tank between first spline and the second spline, and separating groove between being provided with between second spline and the third spline is provided with circular arc parallel key groove on the third spline, first spline and constant head tank between the circular arc transition, transition the arc RADIUS is 5mm, be tapered transition between second spline and the constant head tank, the tapered transition contained angle is 15. This spline shaft simple structure, working process can make the spare part of suit on this spline shaft rather than closely cooperating, reduce the wearing and tearing damaged condition of working process greatly, the service lifetime is prolonged. The problem of very big wearing and tearing appear between external component and the spline shaft in the current spline shaft working process, directly lead to the spline shaft damage even is solved, to extension working life, the damaged condition that reduces to wear and tear has positive meaning.
Description
Technical field
The utility model relates to a kind of splined shaft, belongs to technical field of automobile.
Background technique
Splined shaft is as the component transmitting mechanical torque, and majority of case requires accurately to locate the external component be sleeved on splined shaft, but the splined shaft of prior art is only carry out rough location to external component to make it follow splined shaft action; Make like this to occur very large wearing and tearing between working procedure outer member and splined shaft, even directly cause splined shaft to damage.
Summary of the invention
The purpose of this utility model is: provide one can effectively reduce wearing and tearing in the course of the work, extends the splined shaft of operating life.
The technical solution of the utility model is:
A kind of splined shaft, it is made up of splined shaft body, it is characterized in that: on splined shaft body, interval shape is provided with the first spline, the second spline and the 3rd spline, locating slot is provided with between first spline and the second spline, be provided with interval trough between second spline and the 3rd spline, the 3rd spline be provided with circular arc flat key groove; The radius of arc of circular arc flat key groove is 6mm; Arc transition between the first described spline and locating slot, transition arc radius is 5mm; Be tapering transition between second spline and locating slot, tapering transition angle is 15 °.
Described splined shaft body length is 130mm, diameter 16mm.
The first described spline length is 47mm, and the second flower key length is 52mm.
The utility model has the advantage of:
This spline shaft structure is simple, and working procedure can make the component be sleeved on this splined shaft closely cooperate with it; Greatly reduce the wear damage situation of working procedure; Extend operating life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, splined shaft body, the 2, first spline, the 3, second spline, the 4, the 3rd spline, 5, locating slot, 6, interval trough, 7, circular arc flat key groove.
Embodiment
This splined shaft is made up of splined shaft body 1, on splined shaft body 1, interval shape is provided with the first spline 2, second spline 3 and the 3rd spline 4, locating slot 5 is provided with between first spline 2 and the second spline 3, be provided with interval trough 6 between second spline 3 and the 3rd spline 4, the 3rd spline 4 be provided with circular arc flat key groove 7; The radius of arc of circular arc flat key groove 7 is 6mm.
Arc transition between first spline 2 of this splined shaft and locating slot 5, transition arc radius is 5mm; Be tapering transition between second spline 3 and locating slot 5, tapering transition angle is 15 °.
Splined shaft body 1 length of this splined shaft is 130mm, and splined shaft body 1 diameter is 16mm.First spline 2 length is 47mm, and the length of the second spline 3 is 52mm.
This spline shaft structure is simple, and working procedure can make the component be sleeved on this splined shaft closely cooperate with it; Greatly reduce the wear damage situation of working procedure; Extend operating life.Solve between existing splined shaft working procedure outer member and splined shaft and occur very large wearing and tearing, even directly cause splined shaft to damage problem; To prolongation operating life, reduce wear damage situation and there is positive meaning.
