Embodiment Construction
[0017] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] refer to Figure 1 to Figure 4 As shown, the process of the method for adjusting the high-precision axial clearance of paired deep groove ball bearings in this embodiment is as follows:
[0019] 1. Measure the mounting bearing hole to ensure the accuracy of the bearing hole.
[0020] 2. For a pair of bearings, press one bearing into the corresponding bearing hole, then put the inner washer and outer washer; press the other bearing into the corresponding bearing hole, then put the inner washer and outer washer.
[0021] When pressing the inner gasket and the outer gasket, ensure that the thickness of the outer gasket is greater than that of the inner gasket.
[0022] 3. Compress the outer ring of the bearing wit...

The invention discloses a high-precision axial clearance adjusting method for paired deep groove ball bearings. The high-precision axial clearance adjusting method comprises the following steps that: bearing mounting holes are measured; two bearings in a pair are pressed into the corresponding bearing holes respectively, and then inner gaskets and outer gaskets are placed in the bearing holes; the outer rings of the bearings are tightly pressed by bearing covers; mandrels are inserted into the bearing holes; the mounted double bearings are installed on a supporting frame; iron blocks with known gravity are hung in holes below the mandrels; a tensile machine is hooked in a hole above the mandrels, the tensile machine is pulled upwards to enable the tensile force value of the tensile machine to be the same as the gravity value of the iron blocks, when the force is stable, a micrometer is used to contact the top end surfaces of the mandrels, whether the value of the micrometer is within the range of 0.0005-0.002 is observed, and it is indicated that the clearance is appropriate if the value is within the range; if the value is not within the range, the inner gaskets are ground until the clearance is appropriate. According to the invention, the assembly problem on how to make the axial clearance of paired bearings meet the high-precision requirement under the action of a certain axial force is solved, and the assembly precision of a product is improved.
Description
technical field [0001] The invention belongs to the technical field of optical precision adjustment, and relates to a method for adjusting the high-precision axial clearance of paired deep groove ball bearings, which is suitable for double bearings with a stable rotational speed and an axial clearance accuracy of 0.0005-0.002 under the action of a certain force. deep groove ball bearings. Background technique [0002] In optical precision products, the use of paired deep groove ball bearings ensures the higher coaxiality required by the product, effectively reduces wear to a certain extent, and prolongs the service life of the workpiece; the use of paired bearings can greatly improve the rigidity of the shaft. Better force, improve the stability of optical imaging. [0003] However, the assembly and adjustment of paired bearings is more difficult than that of single bearings, especially under the action of a certain force, the measurement and adjustment of the high-precisio...
