Description
Technical field
The utility model belongs to the bearing detection range, especially a kind of detection model that is used for bidirectional angular contact thrust ball bearing ditch position probing.
Background technology
Bidirectional angular contact thrust ball bearing is owing to be respectively arranged with two ditch raceways on inner ring and outer ring, therefore the problem of two ditch raceways with regard to existing major groove heart distance and ditch heart distance whether to adhere to specification, whether also will detect the ditch radius-of-curvature at major groove heart distance and the ditch heart down apart from adhering to specification adheres to specification, therefore the detection of bidirectional angular contact thrust ball bearing ditch position is different from the detection of common angular contact ball bearing, because common angular contact ball bearing only detects the ditch radius-of-curvature, and bidirectional angular contact thrust ball bearing should detect the major groove heart distance and the ditch heart distance of inner ring or outer ring earlier, detects the ditch radius-of-curvature of inner ring or outer ring with this understanding again.
Detection for bidirectional angular contact thrust ball bearing ditch position can only rely on standard verification spare to compare measurement, and this detection method calibration interval are long, and metage is with expensive, and the instrument adjustment bothers, and efficiency of measurement is low.
Summary of the invention
In order to address the above problem, the utility model has designed a kind of detection model that is exclusively used in bidirectional angular contact thrust ball bearing ditch position probing, uses this detection model can detect the ditch radius-of-curvature of ditch position and the inner ring or the outer ring of bidirectional angular contact thrust ball bearing inner ring or outer ring easily.
For achieving the above object, the utility model adopts following technical scheme:
A kind of detection model that is used for bidirectional angular contact thrust ball bearing ditch position probing is to be made of four semi arch R that are symmetrically distributed on the described model diagonal line, described semi arch R equals the standard ditch radius-of-curvature of tested bidirectional angular contact thrust ball bearing outer ring or inner ring, the mid point of described semi arch R is H, described mid point H equals the tested bidirectional angular contact thrust ball bearing outer ring or the ditch depth of inner ring, the centre distance of wherein said model symmetrically arranged two the semi arch R in upper end is L, described centre distance L equals the major groove heart distance of tested bidirectional angular contact thrust ball bearing outer ring or inner ring, and described centre distance L is serving as a mark with half round cut at middle part, edge, described model upper end; The centre distance of symmetrically arranged two the semi arch R in described model lower end is S, and described centre distance S equals the ditch heart distance of tested bidirectional angular contact thrust ball bearing outer ring or inner ring.
The described detection model that is used for bidirectional angular contact thrust ball bearing ditch position probing, the thickness of described model is greater than the thickness at four semi arch R places.
Owing to adopt technical scheme as mentioned above, the utlity model has following beneficial effect:
1, the utility model detection model of being used for bidirectional angular contact thrust ball bearing ditch position probing has and makes simply, easy to use, detects quick characteristics.
2, use the detection model not need standard verification spare, do not need to adjust instrument, can check all bearings of this model, saved detection time, improved detection efficiency.
3, making the production cost that detects model will examine and determine well below standard component, and puts things right once and for all, and its size accuracy can guarantee 1 year, and the term of validity of standard component only is 3 months.
