PURPOSE:To measure raceway groove pitch accurately and easily by providing an upper and a lower measurement part which are movable in axial directions of a double row raceway bearing and hold balls with holders through ball guide surfaces and raceway groove surfaces. CONSTITUTION:For measuring the raceway groove pitch P1 of the doble row outer ring 21, balls 22 and 23 with holders are fitted in raceway grooves 24 and 25. The balls 23 are supported on the ball guide surface 37 of the lower measurement part 32. A bracket 35 is lowered by sliding on the slide surface 34 of the device to insert the lower end part of the upper measurement part 31 fixed to the bracket 35 into among the balls 22 with holders, and the ball guide surface 36 of the upper measurement part abuts on the surface of the ball 27 of the ball 22, so that balls 27 and 28 of the balls 22 and 23 contact each other at a position where a nominal angle of contact is theta while held between ball guide surfaces 36 and 37. At the same time, the contactor 45 of a measure 43 abuts on the upper surface of the lower measurement part 32 and the pitch P1 is indicated on an indicator 47 in the form of the relative displacement between the measurement parts 31 and 32. Consequently, the raceway groove pitch is measured accurately and easily.

To measure the raceway groove pitch Pa of the double-row outer ring 8, while the side surface 11 of one side of the double-row outer ring is in contact with the reference surface 5 of the measuring device main body, a measuring section is placed on each raceway groove 9 and 10 surface of the double-row outer ring. 3 are brought into contact with each other, and the setting standard value (measured value when measuring the reference master) of the raceway groove position dimension of the double-row outer ring 8 at this time is measured at the measuring part 3. The amount of displacement is indicated by the indicator 7, and the positional dimensions A and B of each raceway groove are measured, and the difference between the measured positional dimensions A and B of each raceway groove is used to determine the raceway groove pitch Po'! However, the raceway groove pitch Po of the double-row outer ring measured in this way is determined by the relative movement of the outer ring and inner ring in the axial direction in a double-row Angiela ball bearing assembled using this double-row outer ring. When this is done, there is a substantial difference from the raceway groove pitch at the position where the rolling elements contact the raceway groove surface of the double-row outer ring. In general, the axial clearance in a double-row angular contact ball bearing is determined by a combination of various factors ζ, including the raceway groove pitch of the bearing ring, raceway diameter and raceway groove radius, and machining dimensional errors such as ball diameter. Therefore, in order to obtain a predetermined axial clearance for the double-row Angiela Tamashima bearing, when assembling the bearing into a string bearing, there is a drawback that the selection and combination of the bearing components, which are the outer ring, inner ring, and balls, is complicated, and the work efficiency is reduced. There is a problem in improving the performance of the bearing, and the raceway groove pitch of the conventional raceway ring has the drawback that it is inappropriate as a representative characteristic value when assembling the bearing.

In the above-mentioned embodiments, as long as the ball comes into contact with the upper measurement part and the groove surface at the position of the nominal contact angle, the shape formed by the surface and the cylindrical surface becomes a circle. It goes without saying that without limitation, those formed with two conical surfaces or those with an arcuate cross-sectional shape are also acceptable. Rotate either the inspection track extension wheel or the pair of upper and lower measuring parts, which is the object to be measured, as the center to stabilize the contact state between the soil surface of the ball with the retainer and each raceway groove of the double row raceway ring. Of course, it is also possible to perform measurements with small measurement errors by doing this.Furthermore, even in the case of a double-row bearing ring or a double-row inner ring, the same measurement method as in the above embodiment can be used to measure the double-row inner ring. There is no need to explain in detail how to measure the orbital groove pitch.
