Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Example 1
As shown in fig. 1-3, the deep groove ball bearing groove processing technology comprises the following steps:
(1) turning, namely turning a channel on the bearing ring in a symmetrical processing mode;
(2) and grinding, namely grinding the turned channel on the bearing ring in a symmetrical processing mode. The tolerance of the position of the groove on the ferrule after grinding is 0.002 mm.
The symmetrical machining means that the position of the groove is calculated using both end surfaces of the bearing ring as reference surfaces.
The bearing ring in this embodiment includes a bearing outer ring 1 and a bearing inner ring 2, and an axial drop is provided between an end surface of the bearing outer ring 1 and an end surface of the bearing inner ring 2 after the bearing inner ring 2 is fitted with the bearing outer ring 1, and the axial drop in this embodiment is 0.04mm to 0.05 mm. Specifically, when the groove on the bearing outer ring 1 is turned and ground, the position of the groove is calculated by taking two end surfaces of the bearing outer ring 1 as reference surfaces; when the groove in the bearing inner ring 2 is turned and ground, the position of the groove is calculated by using both end faces of the bearing inner ring 2 as reference faces.
The tolerance of the dimension C of the two end surfaces of the outer ring 1 after grinding is controlled to be between +0.034mm and +0.040mm (namely, the upper deviation of the dimension C is between +0.040mm, and the lower deviation is between +0.034 mm), and the tolerance of the dimension B of the two end surfaces of the inner ring 2 after grinding is controlled to be between-0.034 mm and-0.040 mm (namely, the upper deviation of the dimension B is between-0.034 mm, and the lower deviation is between-0.040 mm). The position tolerance of the grooves on the bearing outer ring 1 and the bearing inner ring 2 after grinding is 0.002 mm.
In order to ensure the size dispersion and avoid the measurement error, the fine grinding machine is selected to control the size dispersion of the end faces of the ferrules (the bearing outer ring 1 and the bearing inner ring 2) within 0.003 mm.
The influence of the axial clearance on the axial fall is controlled to be between 0.01mm and 0.015mm, and the axial clearance in the embodiment is between 0.006mm and 0.010 mm. It should be noted that, the success rate of the sleeve combination of the bearing ring can be improved by controlling the influence of the axial play on the drop.
In order to eliminate the measurement error, the measurement block gauge and the dial indicator are adopted in the embodiment to measure the end face dimension of the bearing ring. It should be noted that, eliminating the measurement error can improve the success rate of the bearing ring fitting.
Compared with the prior art, the embodiment has the beneficial effects that:
in the embodiment, the grooves on the bearing ring are processed in a symmetrical processing mode, the axial clearance is controlled, and the measurement error is eliminated, so that the axial fall of the end surface of the bearing inner ring 2 and the bearing outer ring 1 after the bearing inner ring and the bearing outer ring are sleeved can meet the requirement completely.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
