[CN 201811268160.9] Bearing installation method of cold heading machine
[CN 201811268160.9] Title of a bearing installation method for a cold heading machine: Application number of a bearing installation method for a cold heading machine: CN 201811268160.9 Applicant: Sijin Intelligent Forming Equipment Co., Ltd. Application date: 2018-10-29 Patent type: Invention application The present invention discloses a bearing installation method for a cold heading machine, which includes adopting a transmission shaft, a bearing and a hydraulic nut, and the transmission shaft is provided with a hydraulic shaft hole, a radial hole and an oil guide groove; one end of the hydraulic shaft hole communicates with the radial hole, and the other end communicates with the outside; the radial hole communicates with the oil guide groove, and the oil guide groove is arranged on the outer side of the transmission shaft and the bearing; one end of the hydraulic nut is in close contact with the inner ring of the bearing, The internal thread is connected with the drive shaft; the installation step is: pass the drive shaft through the bearing according to the installation direction, and connect with the hydraulic nut at the end; fix the bearing, fill oil into the hydraulic nut and the hydraulic shaft hole of the transmission shaft respectively; after the hydraulic nut drives the transmission shaft to move axially to the required installation position, lock the hydraulic nut. The bearing installation method of the cold heading machine described in the present invention is more convenient and faster than hot and cold installation, improves the installation efficiency, and reduces the damage to the transmission shaft and the bearing during the bearing installation process.
