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 angle of flange of cylinder roller bearing.Be applicable to the accurate measurement of angle between cylinder roller bearing ring rib and datum end face, the accurate measurement when being also applicable to arbitrary shape face and datum end face angle and being less than 45 °.
Background technology
At present, the rib of cylinder roller bearing need to be processed rib oblique angle.As shown in Figure 1, rib oblique angle is between rib and datum end face, to have a very little angle, and this angle is determined 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 datum end face location, measure rib to the interior heterodyne on end face height, calculate angle of flange according to the interior heterodyne on effective length and the height measured.The measuring error of this measuring method is mainly derived from:
A) when rib and end face itself is not parallel, rib just exists with the different and multi-form difference in height in cross section from end face, and the error that angle of flange is measured is very large.
B) effective length that rib is measured is subject to the impact of relief groove size and rib chamfer dimesion, and under self small-sized restriction, measuring error is large, has a strong impact on the measurement accuracy of angle of flange.
C) factor such as experience of showing sharp shape and size and survey crew makes at relief groove size and rib chamfer dimesion definite in the situation that, very large to the reading error of flex point, has a strong impact on equally the measurement accuracy of angle of flange.
Be that this measuring method is affected 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 large.
Method 2: measure angle between rib and raceway and calculate angle between rib and datum end face on contourgraph.But prerequisite is not consider the vertical difference of raceway to end face and the shape error of raceway self, thereby error is also very large.The measuring error of this method is mainly derived from the error that 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 between the rib that obtains in this way and end face, angle is affected by the mismachining tolerance of raceway, is different in the measurement result of different cross section equally.
Method 3: measure angle between rib and outer ring internal diameter (inner ring external diameter) and calculate angle between rib and datum end face.The measuring error of this method mainly derives from the error that benchmark disunity brings equally, datum end face is technological datum and machining benchmark, as there is the error of perpendicularity between measuring basis self and machining benchmark end face in outer ring internal diameter (inner ring external diameter), between the rib that this method records and end face, the measuring error of angle is greater than the measuring error of method 2.
