There are two ways to install and disassemble the bearing. First, press the interference ferrule into the shaft or press it into the hole of the bearing housing. First, the inner diameter of the bearing is increased by heating the bearing; or the outer diameter of the bearing is reduced. When the pressurization method is selected, the mechanical force or hydraulic pressure is directly applied to the seat to be disassembled by special equipment; the loading and unloading force is never allowed to pass through the rolling body. Otherwise, the raceway and the tumbler surface indentation will be formed, and the noise and oscillation will be increased to cause damage. If heating or cooling is used for the assembly and disassembly, the heating temperature or cooling temperature should be strictly controlled. The strength of the outer surface of the bearing operation is affected by the metal surface gold. The influence of the phase arrangement layout and the excessive temperature will form a tempering effect. If the temperature is too high, the external appearance will be embrittled. Generally, the heating temperature should not exceed 100 Â°C; the cooling bottom temperature should not be below 50 Â°C. Be even.
Practice has proved that improper bearing equipment is one of the reasons for the premature failure of the bearing. It is not easy to install and remove the ferrule with interference; therefore, when depicting the support; it is necessary to think about how the bearing is assembled and disassembled and convenient. The problem of assembly and disassembly. The assembly and disassembly of large-sized bearings for heavy machinery often requires the depiction of special equipment. If the high-pressure oil is disassembled, it is necessary to draw the oil circuit, pipeline and pump.
