Abstract
The invention relates to a spline assembly centring guiding structure and a processing method thereof. The spline assembly centring guiding structure comprises a spline lever and a spline sleeve. The spline lever is inserted into the spline sleeve. One end of the spline sleeve is provided with a centring guiding ring. A central axis of the centring guiding ring is coaxial with an axis of the spline lever. The inner diameter of the centring guiding ring is fit for the outer diameter of an external spline tooth arranged on the spline lever. According to a pre-action principle, sliding spline tooth side centring is changed into large-diameter centering and the large diameter of the outer spline is accurately pre-processed to form a guiding positioning reference so that tooth side centring-caused deflection is avoided.
Description
Technical field
The present invention relates to a kind of spline pair centering pilot structure and processing method thereof, belong to field of machining.
Background technique
For the flexible large-scale spline pair transmitting torque of longer distance, automatically reset by the elastic force of spring assembly.But in actual use,, in the time automatically reseting, there will be slip not smooth, the situation of being obstructed.
Summary of the invention
The object of the invention is to: a kind of large-scale spline pair structure and processing method thereof of improving is provided, by changing processing datum and increasing centering pilot ring, improves machining accuracy.
The present invention realizes by the following method:
A kind of spline pair centering pilot structure, described guide structure comprises spline rod and spline housing, described spline rod is inserted in spline housing, one end of described spline housing is provided with centering pilot ring, the central axis of described centering pilot ring and spline rod axis coaxle, the internal diameter of described centering pilot ring coordinates with the external spline teeth external diameter being arranged on spline rod.
A Work piece processing method for spline pair centering pilot structure, first accurately processes with the external spline teeth to spline rod, the inner spline gear of processing spline housing using the external spline teeth of spline rod as guide-localization benchmark.
As further innovation of the present invention, described centering pilot ring is of a size of benchmark with the external spline teeth of spline rod and processes, and between the external spline teeth external diameter of the internal diameter of described centering pilot ring and spline rod, is Spielpassung.
beneficial effect
1. adopt action principle in advance, change the centering of free-sliding spline flank the centering of into large footpath and in advance external splines external diameter is accurately processed into guide-localization benchmark, overcome the deflection that flank centering (due to backlash) causes.
2. adopt space separation method: increase centering pilot ring in spline housing end, centering pilot ring internal diameter coordinates with the external spline teeth external diameter of spline rod, reduces the guiding area of the inner spline gear of spline housing, and then reduces surface friction drag.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure: 1, spline housing; 2, splined shaft; 3, centering pilot ring; 4, external splines external diameter.
Embodiment
Be described further below in conjunction with accompanying drawing
As shown in Figure 1, a kind of Work piece processing method of spline pair centering pilot structure, first process with splined shaft 2, take the external environmemt external diameter 4 of splined shaft 2 as guide-localization benchmark, reprocess subsequently spline housing 1, overcome the deflection that flank centering (due to backlash) causes, improved precision, reduced the eccentric resistance that deflection causes.
In one end of spline housing 1, centering pilot ring 3 is set, the external splines external diameter 2 of splined shaft and the internal diameter of centering pilot ring 3 are coordinated, reduce internal spline guiding area, and then reduce surface friction drag simultaneously.
By said method, can make the movement of spline pair guide structure more stable, resistance is also less.
