Abstract
The utility model discloses a kind of spline key side apotting spindle for the packet of internal spline rod spacing, including main shaft, the main shaft is taper plug, the outer surface of the main shaft is provided with external splines, the transverse tooth thickness of the external splines differs certain numerical value every 10mm according to the margin of tolerance, and the external splines, which circumferentially waits, to be distributed.The utility model is mainly used for interior external splines to be grouped, and is coordinated packet zone, to control spline fitted to require.
Description
Technical field
It the utility model is related to apotting spindle technical field, more particularly to a kind of spline for the packet of internal spline rod spacing
Key side apotting spindle.
Background technology
Spline connection is made up of internal spline and external splines.Inside and outside spline is multiple tooth part, the flower on inner periphery
Key is internal spline, and the spline on outer cylinder surface is external splines.Internal spline rod spacing is to represent that one of space width is joined indirectly
Number, is stuck in the relative teeth groove of internal spline with two small poles, measures the size of its internal diameter, here it is internal spline rod spacing, this
Individual small pole is referred to as length bar, and length bar is tangent with the flank of tooth.
It is that spline leads to the measurement of detent plug rule or craft length bar for the existing immediate scheme of internal spline rod distance measurement
Add gauge block measurement.Spline, which leads to detent plug rule, can only judge whether internal spline is qualified, and whether certified products are in the whole margin of tolerance, by hand
With length bar dosage block measurement measurement efficiency it is low, institute it is with teeth all measure it is difficult and unrealistic, and can not measure spline morpheme synthesis
Error.But spline fitted is elastic again related to interior external splines morpheme composition error, only interior external splines is grouped, by packet
Coordinated, preferably spline fitted could be controlled to require.
Utility model content
The utility model is in order to overcome the shortcomings of the prior art, there is provided a kind of for the packet of internal spline rod spacing
Spline key side apotting spindle.
To achieve these goals, the utility model uses following technical scheme：
A kind of spline key side apotting spindle for the packet of internal spline rod spacing, including main shaft, the main shaft are cone
Spend plug, the outer surface of the main shaft is provided with external splines, and the transverse tooth thickness of the external splines is every 10mm according to internal spline
The margin of tolerance differs certain numerical value, and the external splines, which circumferentially waits, to be distributed.External splines on main shaft can be divided into some lattice, often
The transverse tooth thickness of one especially spline is different, and sorted product is set to a certain lattice or connected a few lattice are defined as one group so that spline key
Side apotting spindle can allow sorted product to carry out fast grouping in the whole margin of tolerance, fall in packet zone, then know internal spline
Parameter minor variations, it is especially important to spline fitted.
Preferably, main shaft both ends are respectively equipped with the first split axle body and the second split axle body, the length of the first split axle body
Length of the degree more than the second split axle body.
Preferably, the through hole of a radial direction is offered on the first split axle body, and the radial direction side of the first split axle body
A upward part is plane, and available for the fixation of apotting spindle, the second split axle body is cylindrical axis body.
Preferably, the external splines of the main shaft is 45 ° in the angle of the end chamfer positioned at the first split axle body end, institute
It is 45 ° that the external splines of main shaft, which is stated, in the end chamfer positioned at the second split axle body end.
Therefore, the utility model has the advantages that：
1. spline key side apotting spindle can allow sorted product to carry out fast grouping in the whole margin of tolerance, after packet
Every group of tolerance grade is high, and fit precision accordingly improves；
Disposably 2. the institute of sorted product internal spline with teeth can be measured；
3. spline morpheme composition error can be measured.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, main shaft, the 2, first split axle body, the 3, second split axle body, 4, external splines, 5, through hole, 6, plane.
Embodiment
Below by specific embodiment, and with reference to accompanying drawing, the technical solution of the utility model is made more specifically
It is bright.
As shown in figure 1, a kind of spline key side apotting spindle for the packet of internal spline rod spacing, including main shaft 1, main shaft
Body 1 is taper plug, and the both ends of main shaft 1 are respectively equipped with the first split axle body 2 and the second split axle body 3.
The outer surface of main shaft 1 is provided with external splines 4, and external splines 4, which circumferentially waits, to be distributed, and the transverse tooth thickness of external splines 4 is every
Certain numerical value is differed according to the sorted product internal spline margin of tolerance every 10mm, one group of 2 lattice are pressed in the margin of tolerance, divides 3 groups.
The through hole 5 of a radial direction is offered on first split axle body 2 of main shaft 1, and the first split axle body 2 is in the radial direction
A part be plane 6, the fixation available for apotting spindle.Second split axle body 3 is cylindrical axis body, the first split axle body 2
Length is more than the length of the second split axle body 3.
The external splines 4 of main shaft 1 is 45 ° in the end chamfer positioned at the end of the first split axle body 2, and the external splines 4 of main shaft 1 exists
End chamfer positioned at the end of the second split axle body 3 is 45 °.
Sorted product is inserted in main shaft external splines from apotting spindle the second split axle body during use, according to sorted product
It is inserted in position and carries out internal spline rod spacing fast grouping.Spline key side apotting spindle can allow sorted product in the whole margin of tolerance
Interior carry out fast grouping, every group of tolerance grade after packet is high, and fit precision accordingly improves, and can be disposably to sorted product
The institute of internal spline is with teeth to be measured, moreover it is possible to which spline morpheme composition error is measured.
It is not new to this practicality although above-mentioned specific embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability
Field technique personnel need not pay the various modifications that creative work can make or deformation still in protection model of the present utility model
Within enclosing.
