Abstract
The utility model relates to a spline key side setting spindle that is used for internal spline stick interval stepping, including the main shaft body, main shaft body both ends be equipped with the branch axis body respectively, and first minute axis body, second divide the axis body, the outside of this main shaft body is equipped with to be on the surface waits the external splines of dividing equally cloth, has offered a radial through -hole on the first minute axis body of this main shaft body, and the radial side of this first minute axis body ascending some be the plane, this second divides the axis body to be the columniform axis body, the length of first minute axis body is greater than the length that the second divides the axis body, the external splines of the main shaft body, be 45 in the terminal surface chamfer that lies in first minute axis body end, be 6 lieing in the terminal surface chamfer that the second divides axis body end, the beneficial effects of the utility model are that: spline key side setting spindle can carry out quick stepping in whole tolerance range, drop on the stepping district, then knows the tiny change of internal spline parameter, carries out the stepping to changing data, and is important very much to the spline fit.
Description
Technical field
This utility model belongs to apotting spindle technical field, particularly relates to a kind of spline key side apotting spindle for internal spline interrod spacing stepping.
Background technology
Existing utilize the logical detent plug rule of spline to judge that whether involute inner spline is qualified, but can not solve internal spline is carried out stepping qualitative reaction; The logical detent plug rule of internal spline can only judge that whether it is qualified, and certified products are in the whole margin of tolerance. But spline fitted degree of tightness is relevant to inside and outside Parameter of spline, only interior external splines is carried out stepping, make stepping district coordinate, spline fitted requirement could be controlled.
Summary of the invention
The purpose of this utility model is in that the deficiency overcoming prior art to exist, and provides a kind of spline key side apotting spindle for internal spline interrod spacing stepping.
The purpose of this utility model completes by following technical solution, and including main shaft, described main shaft is respectively arranged at two ends with split axle body and the first split axle body, the second split axle body; It is wait the external splines being all distributed that the outer surface of this main shaft is provided with, first split axle body of this main shaft offers a through hole radially, and a part in the radial direction for this first split axle body is plane, this the second split axle body is cylindrical axis body, and the length of the first split axle body is more than the length of the second split axle body.
As preferably, the external splines of described main shaft, is 45 �� being positioned at the end chamfer of the first split axle body end; It it is 6 �� being positioned at the end chamfer of the second split axle body end.
The beneficial effects of the utility model are: spline key side apotting spindle can carry out quick stepping in the whole margin of tolerance, drops on stepping district, then know internal spline parameter minor variations, delta data is carried out stepping, to spline fitted particular importance.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model looks cross-sectional view.
Fig. 2 is the A-A cross-sectional view of figure.
Label in accompanying drawing is respectively as follows: 1, main shaft;2, the first split axle body; 3, the second split axle body; 11, external splines; 21, through hole; 22, plane.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model done detailed introduction: as shown in accompanying drawing 1,2, this utility model includes main shaft 1, and described main shaft 1 is respectively arranged at two ends with split axle body and first split axle body the 2, second split axle body 3; It is wait the external splines 11 being all distributed that the outer surface of this main shaft 1 is provided with, first split axle body 2 of this main shaft 1 offers a through hole 21 radially, and a part in the radial direction for this first split axle body 2 is plane 22, this the second split axle body 3 is cylindrical axis body, and the length of the first split axle body 2 is more than the length of the second split axle body 3.
The external splines 11 of described main shaft 1, is 45 �� being positioned at the end chamfer of the first split axle body 2 end; It it is 6 �� being positioned at the end chamfer of the second split axle body 3 end.
It is that spline key side coordinates because involute spline coordinates, then adopts involute spline key side apotting spindle; Adopt the involute spline key side apotting spindle having length and tapering relation, the longitudinally tiny scope of Parameter of spline in each district of stepping, then can carry out the quick stepping of internal spline interrod spacing.
This utility model is not limited to above-mentioned embodiment; no matter doing any change on its shape or material are constituted; every employing structural design provided by the utility model, is all a kind of deformation of the present utility model, is all considered as within this utility model protection domain.
