Problems solved by technology

Using the above method to assemble bearings not only has the problems of complex production process, high production cost, high labor intensity, and low labor efficiency, but also the grinding debris during the grinding process will enter the bearing when the end surface protrusion of the finished bearing is ground. The bearing accuracy is affected by the gap between the inner and outer rings

Embodiment 1

[0027] Embodiment 1 of the angular contact ball bearing assembly method of the present invention includes the following steps:

[0028] The first step is to design the position a of the outer ring groove 11 on the outer ring 1 of the angular contact ball bearing e so that it satisfies formula 1: a e =B / 2+(R i +R e -D w )*sinα+δ;

[0029] In the second step, the first end and the second end of the inner ring 2 of the angular contact ball bearing are marked as the A end face 22 and the B end face 23 respectively, and the position a of the inner ring groove 21 of the angular contact ball bearing is designed i Make it satisfy formula 2: a i =B / 2+β, the value of β in the formula takes any value between -0.1 and 0 according to the accuracy of the machine tool;

[0030] In the third step, take T=B+2*(R i +R e -D w )*sinα-2*a e , adjust the δ value in the first step so that the T value is -2δ a , Record the above formula as formula 3;

[0031] The fourth step is to proce...

Embodiment 2

[0039] The difference between Embodiment 2 of the method for assembling angular contact ball bearings of the present invention and Embodiment 1 of the method for assembling angular contact ball bearings is only that in the sixth step, the protrusion amount of the finished bearing manufactured in the fifth step For measurement, select angular contact ball bearings with opposite signs of protrusion values ​​and equal absolute values ​​for back-to-back assembly to form a bearing assembly.

[0040] Specifically, when the bearings need to be assembled back-to-back, measure the bearing I and the bearing II respectively to find out a bearing I and a bearing II, and make the protruding values ​​of the two bearings found have opposite signs and absolute The values ​​are equal, and then the two bearings are assembled back-to-back. After the assembly, the wide-side end faces of the outer rings of the two bearings face each other so that the load line of the two bearings is "O"-shaped.

Abstract

The invention relates to an angular contact ball bearing, a bearing assembly, a manufacturing method and an assembling method thereof. The center of a bearing inner ring groove manufactured by the manufacturing method provided by the invention is not certainly located at the dead centre of an inner ring but can be close to the first end of the inner ring, so that the machining difficulty is reduced by way of permitting machining deviation. Meanwhile, when the manufactured inner ring fits an outer ring based on the first end, the convex value of a manufacturing bearing I is a positive value. When the manufactured inner ring fits the outer ring based on the second end, the convex value of a manufacturing bearing II is a negative value. Therefore, proper bearings can be selected to be correspondingly assembled by measuring the convex values of the bearings, so that coping of the convex values of the bearings is avoided.

Description

technical field [0001] The invention relates to an angular contact ball bearing, a bearing assembly, a manufacturing method and an assembly method thereof. Background technique [0002] The preload that a matched angular contact ball bearing can carry is determined by the protrusion of a single matched bearing. The protrusion of the bearing refers to the relative position of the non-reference end surface of the bearing inner ring relative to the reference end surface of the outer ring under the specified measurement load. When it is protruding, the protrusion is a positive value; when it is recessed, Bulge is a negative value. The method of bearing assembly in the prior art is to process the angular contact ball bearing with positive protrusion first, then grind the protrusion of the angular contact ball bearing according to the dimensional relationship that needs to be satisfied during assembly, and then Assemble the multiple sets of bearings after grinding. When assembl...
