Abstract
The invention relates to a serialized method for measuring groove diameters of inner and outer rings of a noncircular-channel bearing, belongs to the technical field of bearing technology detection and mainly aims to solve the problem that groove diameters of inner and outer rings of a noncircular-channel bearing cannot be directly measured at present. The method is mainly characterized in that D012 and D022 bearing instruments, a finished bearing steel ball and standard outer and inner ring samples are adopted, the diameter of the finished bearing steel ball is taken as the groove curvature of the standard outer ring sample, and a theoretical groove bottom diameter converted from a rounding diameter in a figure is taken as the channel diameter of the standard outer ring sample; the standard outer ring sample is placed on one bearing instrument, and a pointer of a dial indicator is adjusted to point at the 0 position which is the theoretical size of the channel diameter of the stand ring samples; and then the stand ring samples are taken down, a to-be-detected outer ring and a to-be-detected inner ring are put on the bearing instruments and are rotated by one circle, and numerical readings on the instruments and the amount of variation are respectively the actual sizes of the groove diameters of inner-ring and outer-rings grooves and the deviation. The method has the characteristics of direct measurement, accurate measurement, high efficiency and higher product matching rate and is mainly used for serialized measurement of the groove diameters of the inner and outer rings of the noncircular-channel bearing.

(2) first inner ring standard sample circle is placed on D022 bearing instrument, design D022 bearing instrument fulcrum, measuring point is bearing finished products steel ball, adjust clock gauge moves axially on bearing instrument, when clock gauge indicating value hour, fixedly clock gauge axial location, now adjusts indicator on clock gauge and makes to be indicated to 0, and 0 is inner ring ditch footpath theoretical size;
(3) then take off inner ring standard sample circle, product inner ring to be detected is placed on D022 bearing instrument, rotate a circle, instrument, read value is product bear inner ring grooved railway ditch footpath physical size.
The present invention is owing to adopting D012 bearing instrument or D022 bearing instrument, bearing finished products steel ball and outer ring standard sample circle or inner ring standard sample circle, take the ditch curvature of bearing finished products steel ball size Dw * 0.53 as outer ring standard sample circle, the theoretical core diameter that the fourth contact diameter of take in bearing products figure converses is standard sample Quan Gou footpath, outer ring, thereby Ke Xianjiang outer ring standard sample circle is placed on D012 bearing instrument or by inner ring standard sample circle and is placed on D022 bearing instrument, adjust indicator on clock gauge and make to be indicated to 0, 0 Wei Wei outer ring or inner ring ditch footpath theoretical size, then take off outer ring standard sample circle or inner ring standard sample circle, product outer ring to be detected or inner ring are placed on D012 bearing instrument or D022 bearing instrument, rotate a circle, instrument, read value is product outer ring or bear inner ring grooved railway ditch footpath physical size.
The invention has the beneficial effects as follows, directly measure the ditch footpath of Internal and external cycle, measure accurately, efficiency is high, cancels supporting ditch footpath dimension conversion, has improved the supporting rate of product, and Hai Kegou footpath processing site is used in addition.
The present invention is mainly used in the direct measurement in the non-round raceway groove bearing enclose ditch of seriation footpath.
