Abstract
The utility model provides a kind of motor shaft spline end, and spline end entirety is made up of axle core, and the outer rim of axle core processes groove, forms spline-shaped, and axle core adopts 42CrMo steel to be made.A kind of motor shaft spline end of the utility model, quenching effect is good, can ensure good hardness, intensity and mechanical property, durable in use, extends the working life of motor shaft.
Description
Technical field
The utility model relates to a kind of motor shaft spline end.
Background technique
New energy bus motor shaft, what two ends adopted is spline end.And centered by the structure of existing spline end, being axle core, outer rim is then set with spline housing, after Quenching Treatment, the hardness of the two, intensity, mechanical property there are differences, and again because spline end place diameter is less, easily produce metal fatigue, cause termination to be ruptured, cause the damage of motor shaft.
Model utility content
The technical problems to be solved in the utility model overcomes existing defect, provides a kind of motor shaft spline end, ensure good hardness, intensity and mechanical property, durable in use, extends the working life of motor shaft.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of motor shaft spline end, described spline end entirety is made up of axle core, and the outer rim of described axle core processes groove, forms spline-shaped.
Further, described axle core adopts 42CrMo steel to be made.
A kind of motor shaft spline end of the utility model, quenching effect is good, can ensure good hardness, intensity and mechanical property, durable in use, extends the working life of motor shaft.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of motor shaft spline end of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of motor shaft spline end, spline end entirety is made up of axle core 1, and the outer rim of axle core 1 processes groove 2, forms spline-shaped.This spline end is made up of an entirety, and after quenching, hardness, intensity and mechanical property are all consistent, and effectively avoid the generation of metal fatigue, long service life.
Axle core adopts 42CrMo steel to be made, and this material, when experiencing quenching, can reach and quench completely, and the global density of retainer shaft core is consistent, thus ensures good hardness, intensity and mechanical property.
A kind of motor shaft spline end of the utility model, quenching effect is good, can ensure good hardness, intensity and mechanical property, durable in use, extends the working life of motor shaft.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (1)
