Abstract

The utility model relates to a kind of sprocket shaft group axle spline manufacturing structure again, and it is characterized in that being provided with splined shaft (2) in spline housing (1), splined shaft (2) is provided with key (3), and splined shaft (2) is fixedly connected with spline housing (1) inwall by key (3).Simple and reasonable due to what select, after spline housing damages, splined shaft can continue to use by other spline housing supporting, ensures that manufacturing axle spline performance is again equal to primitive axis, reduces cost, extends the working life of sprocket shaft group.

Description

Sprocket shaft group axle spline manufacturing structure again
Technical field
The utility model relates to coal excavation apparatus and repairs field, is specifically related to a kind of sprocket shaft group axle spline manufacturing structure again.
background technique:
sprocket shaft group is critical piece in scrapper conveyor, and axle is the strength member in sprocket shaft group, axle spline because of transmit moment of torsion very large, in use very easily scroll key and wearing and tearing, current most domestic sprocket shaft group enterprise, when keeping in repair axle spline, all adopts and carries out built-up welding polishing to spline, do not reach original precision and intensity, working life is shorter, and splined shaft and spline housing as a whole, spline housing one is scrapped, and entirety is all scrapped, cause waste, the working life of sprocket shaft group cannot be ensured.The normal use of equipment can not be ensured, to the economic loss that ore deposit side causes stopping production to bring.
Summary of the invention
The purpose of this utility model is the defect in order to overcome prior art, provides a kind of sprocket shaft group axle spline manufacturing structure again, thus efficiently solves problems of the prior art.
The technological scheme taked for realizing the purpose of this utility model is: a kind of sprocket shaft group axle spline manufacturing structure again, it is characterized in that being provided with splined shaft (2) in spline housing (1), splined shaft (2) is provided with key (3), and splined shaft (2) is fixedly connected with spline housing (1) inwall by key (3).
It is characterized in that described key (3) has two at least, and evenly arrange.
The beneficial effects of the utility model are: simple and reasonable due to what select, and after spline housing damages, splined shaft can continue to use by other spline housing supporting, ensures that manufacturing axle spline performance is again equal to primitive axis, reduces cost, extends the working life of sprocket shaft group.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
The A direction view of Fig. 2 the utility model Fig. 1;
In figure: 1-spline housing, 2-splined shaft, 3-key.
Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment 1: see Fig. 1,2, and a kind of sprocket shaft group axle spline manufacturing structure again, it is characterized in that being provided with splined shaft 2 in spline housing 1, splined shaft 2 is provided with key 3, and splined shaft 2 is fixedly connected with spline housing 1 inwall by key 3.
It is characterized in that described key 3 has two at least, and evenly arrange.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, 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.
