Description
Technical field
The present invention relates to the technical field of bearing measuring, relate in particular to a kind of method and device of measuring the rib angle of cylinder roller bearing.Be applicable to the accurate measurement of angle between cylinder roller bearing lasso rib and datum end face, the accurate measurement when also being applicable to arbitrary shape face and datum end face angle less than 45 °.
Background technology
At present, the rib of cylinder roller bearing need be processed the rib oblique angle.As shown in Figure 1, the rib oblique angle is that a very little angle is arranged between rib and datum end face, and this angle is confirmed by design between 10 '～1 °.At present, the universal measurement method at the rib oblique angle of cylinder roller bearing has three kinds:
Method 1: the interior heterodyne of measuring rib: with the datum end face location, measure rib, calculate the rib angle according to effective length of measuring and the interior heterodyne on the height to the interior heterodyne on the end face height.The measuring error of this measuring method is mainly derived from:
When a) rib and end face itself was not parallel, rib and end face made that with regard to existing with the different and multi-form difference in height in cross section the error of rib measurement of angle is very big.
B) effective length measured of rib receives the influence of relief groove size and rib chamfer dimesion, and under self small-sized restriction, measuring error is big, has a strong impact on the measurement accuracy of rib angle.
C) factors such as experience of the shape and size of table point and survey crew make under relief groove size and the definite situation of rib chamfer dimesion, and are very big to the reading error of flex point, have a strong impact on the measurement accuracy of rib angle equally.
Be that this measuring method is influenced by the experience of rib parallel error, rib chamfer dimesion, relief groove size, the shape of measuring gauge outfit and size, survey crew, error is very big.
Method 2: calculate angle between rib and datum end face measuring between rib and raceway angle on the contourgraph.But prerequisite is not consider raceway to the vertical difference of end face and the shape error of raceway self, thereby error is also very big.The measuring error of this method is mainly derived from the error that the benchmark disunity brings; Datum end face is technological datum and machining benchmark; Raceway is as having the error of perpendicularity between measuring basis self and machining benchmark end face; That is to say that angle is influenced by the mismachining tolerance of raceway between the rib that obtains in this way and end face, the measurement result at different cross section is different equally.
Method 3: angle is calculated angle between rib and datum end face between measurement rib and outer ring internal diameter (inner ring external diameter).The measuring error of this method mainly derives from the error that the benchmark disunity brings equally; Datum end face is technological datum and machining benchmark; Outer ring internal diameter (inner ring external diameter) is as existing the error of perpendicularity between measuring basis self and machining benchmark end face, and the measuring error of angle is greater than the measuring error of method 2 between rib that this method records and end face.
