The installation and removal method of the bearing of the self feeding mixer truck shall be determined according to the structure, size and matching nature of the bearing. The installation and removal pressure shall be directly applied to the end face of the tight fitting retainer ring, and the pressure shall not be transmitted through the rolling element.
This will cause indentation on the working surface of the bearing, affect the normal operation of the bearing, and even damage the bearing. The cage, seal ring, dust cover and other parts of the bearing are easy to deform, and the pressure for installing or disassembling the bearing cannot be applied to these parts. From the manufacturer of charging mixer truck
The inner ring of the bearing is closely fitted with the shaft, and the outer ring is loosely fitted with the housing. Press the bearing onto the bearing with a press, and then install the shaft and the bearing into the housing. When pressing, pad a soft metal assembly sleeve (copper or soft steel pipe) on the end face of the bearing.
According to the manufacturer of the loading mixer truck, the inner ring of the bearing and the shaft, and the outer ring and the housing hole are closely matched. The end face of the assembly sleeve should be made into a ring that can compress the end face of the inner and outer rings of the bearing at the same time, or a disc and the assembly sleeve should be used to make the pressure transfer to the inner and outer rings at the same time, so as to press the shaft into the shaft and the housing. This installation method is especially suitable for the installation of radial spherical bearing with automatic centering.
