Problems solved by technology
Since the gap between the bearing and the main shaft of the vacuum pump is very small, it takes a lot of manpower to install, and a vacuum pump has four bearings, and the installation workload is relatively large: during the installation process, after the ferrule is put on, manual use is required The heavy hammer relies on strong force to press the bearing into the main shaft. First, it is inconvenient to operate. Second, the operator’s workload is very heavy and the installation efficiency is very low. Third, in the process of pressing in with a heavy hammer, careless operation may damage the pump body or cause operator personal injury

The invention belongs to the technical field of vacuum pump bearing mounting, and particularly relates to a vacuum pump bearing mounting device and a bearing mounting method. The mounting device comprises a supporting frame, a pushing device, a sleeve and a refrigerating device. The supporting frame is arranged outside a vacuum pump in a sleeving manner. The pushing device is detachably connected to the supporting frame and used for providing pushing force. One end of the sleeve is detachably connected to the pushing device, the other end of the sleeve is provided with an opening, the other end of the sleeve can abut against a bearing, and a main shaft of the vacuum pump can be sleeved with the opening. The refrigerating device can cool the main shaft. According to the vacuum pump bearing mounting device, the refrigerating device can cool the main shaft so that the outer diameter of the main shaft can become smaller, the gap between the main shaft and the bearing is increased, and the pushing device can conveniently push the bearing through the sleeve; compared with a manual hammering type mounting method, the workload of operators is reduced, the work difficulty is lowered, the mounting efficiency is improved, a pump body cannot be damaged or personal injuries of the operators cannot be caused, and safety is high; and according to the bearing mounting method, the operation steps are simple, and the manual workload is small.
Description
technical field [0001] The invention relates to the technical field of vacuum pump bearing installation, in particular to a vacuum pump bearing installation device and a bearing installation method. Background technique [0002] Existing ship blasting workshops require the use of large vacuum pumps, which often require maintenance. During maintenance, it is necessary to remove the bearings on both ends of the vacuum pump, and reinstall the bearings after the maintenance. Since the gap between the bearing and the main shaft of the vacuum pump is very small, it takes a lot of manpower to install, and a vacuum pump has four bearings, and the installation workload is relatively large: during the installation process, after the ferrule is put on, manual use is required The heavy hammer relies on strong force to press the bearing into the main shaft. First, it is inconvenient to operate. Second, the operator’s workload is very heavy and the installation efficiency is very low. Th...
