Roller press quality appraisal can be analyzed from the following aspects:
1. Roller press bearing wear problem
The original static fit between the bearing and the bearing seat failed for some reasons, resulting in dynamic friction between the bearing and the bearing seat (commonly known as the phenomenon of bearing running in the inner circle), which in turn caused metal wear problems in the bearing seat.
2, roller press locking plate hollow shaft and sleeve wear problem
Since the expansion sleeve part bears a large torque, the mating surface of the central shaft and the sleeve will move relative to each other during long-term operation, resulting in wear between the sleeve and the shaft head, and the expansion sleeve cannot be locked, causing shutdown.
3, planetary gear reducer bearing chamber wear
roller press reducer bearing chamber wear is a common problem of transmission part wear. Traditional repair welding machine processing or brush plating spraying solutions have certain limitations. The application of polymer composite materials for online repair is an effective means to solve the transmission part wear on site.
4, leakage problem
Planetary gear reducer oil leakage is a common problem. The reasons for reducer oil leakage include unreasonable lubrication structure design, unreasonable lubricating material selection, unreasonable reducer structural design, etc.
