率も極めて悪いという欠点があつた。 C=Q 2 +Q 3 -Q 1 -2D・sinΘ (1) In the conventional assembly method of inner ring separated type angular contact ball bearings, the contact point pitch of the raceway groove of the double row outer ring in equation (1) Q 1 and each single row Since it is difficult to accurately measure the raceway groove contact point position dimensions Q 2 and Q 3 of the inner ring, the raceway groove pitch P 1 of the double-row outer ring, which is easy to measure, and the raceway groove position dimensions of each single-row inner ring are
This was done by estimating a predetermined axial clearance C from P 2 , P 3 and the ball diameter D, and selecting a combination of the double-row outer ring 2, the single-row inner rings 3 and 4, and the balls 5. However, the axial clearance C of a separable inner ring angular ball bearing is the same as the raceway groove pitch of the double row outer ring.
In addition to the characteristic factors of P 1 , raceway groove position dimensions of each single row inner ring P 2 , P 3 and ball diameter D, outer ring raceway groove radius
The influence of various characteristic factors based on machining dimensional errors such as R 1 , R 2 , inner ring raceway groove radius r 1 , r 2 , maximum outer ring raceway diameter A 1 , A 2 , maximum outer ring raceway diameter B 1 , B 2 , etc. As a result, the fit rate of the combination of double-row outer ring and single-row inner ring is poor, and in order to guarantee the allowable value of axial clearance C, it is necessary to perform a 100% inspection after assembly, and the defective rate of axial clearance is also high. There were flaws. In addition, in order to assemble the bearing components so as to obtain an axial clearance within a predetermined tolerance, several types of balls 5 with different ball diameters are prepared in advance, and the double-row outer ring 2, the single-row inner rings 3 and 4, and the balls 5 are prepared in advance. It is necessary to select from a large number of combinations of each machining dimension characteristic value of No. 5, and the selection and combination work is complicated and the work efficiency is extremely low.

In a double-row angular ball bearing with separate raceway rings, which selects and combines multiple single-row bearing rings and a plurality of balls that are fitted into raceway grooves provided in a double-row bearing ring and a single-row bearing ring. , the raceway groove contact point pitch of the double-row raceway obtained by measuring the interval between the nominal contact angle positions on each raceway groove surface of the double-row raceway, and the nominal contact angle from the front to the raceway groove surface of the single-row raceway ring. It has the feature that a predetermined axial clearance can be easily obtained by selecting a combination of position dimensions and ball diameter of the balls. The fitting rate of the combination with the inner ring is increased, the work of selecting and assembling the bearing components becomes easier, and the occurrence of axial clearance defects after assembly is eliminated, resulting in a marked improvement in guaranteed accuracy.

ラ玉軸受の組立方法。1 One double-row bearing ring, two single-row bearing rings,
In a double-row angular ball bearing with separate raceway rings in which a plurality of balls fitted into raceway grooves provided in a double-row raceway ring and a single-row raceway ring are selected and combined, each of the double-row raceway rings Balls with a retainer are inserted into the raceway grooves, and the balls are held by ball guide surfaces formed at opposing ends of an upper measuring section and a lower measuring section that are relatively movable in the axial direction of the double-row raceway ring. The relative displacement in the axial direction between the upper measurement section and the lower measurement section is determined by holding the cage attachment balls and bringing the cage attachment balls into contact with the position of the nominal contact angle on the raceway groove surface of the double-row raceway ring. The raceway groove contact point pitch of the double-row raceway obtained by measuring the contact point pitch of the raceway groove of the double-row raceway, and the single-row raceway that was placed on the reference surface by inserting the cage-attached balls into the raceway groove of the single-row raceway. A ball guide surface formed in a single-row raceway ring measuring section movable in the axial direction of the ring is brought into contact with the ball with the cage, and the ball guide surface formed on the single-row raceway ring measuring section movable in the axial direction of the ring is brought into contact with the ball guide surface at the nominal contact angle position on the raceway groove surface of the single-row raceway ring. The position and dimension of the contact point of the raceway groove of the single-row raceway ring obtained by contacting the cage-attached balls and measuring the relative displacement between the front surface of the single-row raceway ring and the single-row raceway measurement part, and the ball A method for assembling a double-row angular ball bearing with separate raceway rings, characterized by selecting a combination with ball diameters to obtain a predetermined axial clearance.
