On August 22, the planetary gear roller bearing disassembly and assembly device for electric truck wheels independently invented and designed by Shengli Energy’s Equipment Maintenance and Repair Center was successfully put into use. This device can effectively solve problems such as frequent displacement, multi-person combined operation, and operation in small spaces caused by the use of traditional heavy-duty hydraulic jacks, thus improving the disassembly and assembly efficiency while ensuring safe operation.
Compared with the traditional dismounting method, the device can reduce personnel investment by 50% and increase dismantling efficiency by 60%, not only enhancing safety but also guaranteeing efficient replacement of planetary gear roller bearings.
