Abstract
Description
Technical Field
[0001] The utility model relates to the field of bearing assembly presses, and particularly to a rolling guide roller bearing assembly press for a high-speed wire rod rolling mill. Background Technique
[0002] The guide roller bearing is an essential and important component for supporting the operation of the guide roller. Incorrect installation methods, such as improper bearing installation, will not only affect the service life of the bearing, but more likely cause production accidents. Therefore, it must be taken seriously. Directly hitting the bearing into the guide roller with a hammer is an incorrect installation method for the bearing, which is not only likely to cause bearing deformation, reducing the service life of the bearing, but also likely to bring impurities into the bearing, causing bearing burnout. During assembly, ensure that the bearing is evenly stressed and enters the shaft hole of the guide roller to avoid bearing deformation and the entry of impurities caused by uneven stress. For this reason, we provide a rolling guide roller bearing assembly press for a high-speed wire rod rolling mill. Content of the Utility Model
