Description

A kind of spiral bevel gear flank of tooth curvature interference method of inspection
Technical field
The invention belongs to gear mesh analysis technical field of measurement and test, and in particular to a kind of spiral bevel gear flank of tooth curvature interference The method of inspection.
Background technology
At the contact point it is the essential condition of realizing correct engagement without curvature interference during two flank engagements.In Gear Processing As the factors such as machine tool error, alignment error, heat treatment deformation cause larger tooth surface error, occur when two coupling gears are engaged Flank of tooth curvature interference and cannot correct engagement.
The inspection of flank of tooth curvature interference is only calculated in tooth surface design phase analyses at present, by the phase for calculating two tooth face meshing points The method is the determination methods based on local topology to be judged to normal curvature and relative Geodesic torsion.Such as Shen Yunbo, side In the paper " method of face gear drive engagement process Relative normal curvature interference detection " of ancestor's moral et al., it is proposed that a kind of face gear The method of the Relative normal curvature extremal curvature interference inspection of whole engagement process is driven, the method is a kind of based on local The determination methods of topological structure, the gear pair of machined mistake need pairing rolling inspection is carried out on rolling inspection machine, by rolling tested stamp trace according to The particular location and degree of micro-judgment flank of tooth curvature interference.
In addition, gear measuring center carry out three coordinate measurement of the flank of tooth become the flank of tooth detection important means, but this Measurement and analysis of the detection of kind of the flank of tooth just for the tooth accuracy of single gear, it is impossible to two flank engagement performances are carried out point Analysis.
The content of the invention
It is an object of the invention to provide a kind of spiral bevel gear flank of tooth curvature interference method of inspection, it is only necessary to provide two flank of tooth Some discrete points coordinate figure, you can accurately judge the position of flank interference and which can be surveyed the position of engagement to carry out Anticipation.
In order to realize object above, the technical solution adopted in the present invention is：A kind of spiral bevel gear flank of tooth curvature interference The method of inspection, comprises the steps：
