Abstract
The present invention relates to a kind of method for measuring axial gap after universal joint assembles, step are as follows：(1) left gap is eliminated：Left and right end face is fixed, applies pressure 1 on axle sleeve, measures right survey difference in height h1；(2) right end clearance is eliminated：Left and right end face is fixed, applies pressure 2, measurement right side difference in height h2 on axle sleeve；(3) press fitting rear universal joint axial gap H=h1 h2 are calculated.The invention has the advantages that：The present invention has been quantified assembling quality, the influence that element precision is judged technological level height is completely eliminated, is lifted and pointed the direction for subsequent technique by axial gap after measurement assembling universal joint.It is of the invention effectively to quantify power transmission shaft middle part universal joint assembling quality, solve the problem of the not energetic middle part universal joint assembling quality of traditional universal joint staring torque.
Description
Technical field
The present invention relates to measuring method, especially a kind of method for measuring axial gap after universal joint assembles.
Background technology
The vehicle driving shaft assembly of Hooke's joint formula is measurement universal joint to the evaluation method of universal joint assembling quality
Staring torque, this kind of measuring method have quantified universal joint assembling quality.
The size of universal joint staring torque is determined by axial gap after the machining accuracy of part and assembling etc..And staring torque
Although having quantified assembling quality, influence factor occurs two or more than two, and manufacturing works are difficult the root for problem of finding out
Source simultaneously proposes effective control measure.This consequence is exactly that the universal joint staring torque scattered error after assembling will appear from larger deviation,
It is even uncontrollable when serious.The defects of particularly pointing out is, by taking the power transmission shaft of two sections or more section as an example, the universal joint of middle part
Staring torque is undetectable.
The content of the invention
The invention solves the shortcomings that above-mentioned prior art, there is provided after a kind of Detection results preferably measure universal joint assembling
The method of axial gap.
The present invention solves the technical scheme that its technical problem uses：The side of axial gap after this measurement universal joint assembling
Method, step are as follows：
(1) left gap is eliminated：Left and right end face is fixed, applies pressure 1 on axle sleeve, measures right survey difference in height h1；
(2) right end clearance is eliminated：Left and right end face is fixed, applies pressure 2, measurement right side difference in height h2 on axle sleeve；
(3) press fitting rear universal joint axial gap H=h1-h2 is calculated.
The concrete numerical value of the pressure 1 and pressure 2 finally determines after being supported by test data.
The test pressure of the pressure 1 and pressure 2 increases step by step in certain intervals, take that gap width is relatively stable one group
As final selected pressure.
The invention has the advantages that：Axial gap after the assembling universal joint of the invention by measurement, has quantified assembling quality,
The influence that element precision is judged technological level height is completely eliminated, is pointed the direction for subsequent technique lifting.Effective dose of the present invention
Change power transmission shaft middle part universal joint assembling quality, solve the not energetic middle part universal joint of traditional universal joint staring torque
Assemble the problem of quality.
Brief description of the drawings
Fig. 1 is detects schematic diagram of the present invention；
Fig. 2 is measuring basis schematic diagram.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As illustrated, this method for measuring axial gap after universal joint assembles, step are as follows：
(1) left gap is eliminated：Left and right end face is fixed, applies pressure 1 on axle sleeve, measures right survey difference in height h1；
(2) right end clearance is eliminated：Left and right end face is fixed, applies pressure 2, measurement right side difference in height h2 on axle sleeve；
(3) press fitting rear universal joint axial gap H=h1-h2 is calculated.
The concrete numerical value of pressure 1 and pressure 2 finally determines after being supported by test data.The test pressure of pressure 1 and pressure 2
Increasing step by step in certain intervals, take gap width relatively stable one group is used as finally selected pressure, such as 100N, 200N,
300N ... is incremented by successively.
The present invention assembles rear universal joint axial gap by detecting, and quality is assembled using resulting gap width as judge
Quantization parameter.Judgment basis of the axial gap as assembling quality, can avoid the other factors such as the part accuracy of manufacture
Influence, effectively instruct assembly technology to improve.
In addition to the implementation, the present invention can also have other embodiment.It is all to use equivalent substitution or equivalent transformation shape
Into technical scheme, all fall within the protection domains of application claims.
