Crossed roller bearing internal clearance choice points

The so-called bearing internal clearance, which are not installed on the bearing on the shaft or bearing box, a fixing the inner or outer, then that is not a fixed one measuring 

radial or axial movement of the mobile. According to the movement direction, radial clearance and axial clearance can be. Crossed roller bearing internal clearance choice points 

called bearing internal clearance, which are not installed on the bearing on the shaft or bearing box, a fixing the inner or outer, then that is not a party to the fixed

The amount of axial movement of the mobile or. According to the movement direction, can be divided into radial clearance and axial clearance. On the measurement of bearing 

clearance in the interior, in order to make the measurement value is stable, general test load was applied in the ring. Therefore, the test value than the actual clearance 

value, namely one more test applied load and elastic deformation. Bearing clearance operation, because the bearing with inner and outer rings and cause temperature, than the 

initial clearance of small. Running clearance and the flange bearing life, Wen Sheng, vibration and noise are closely related, so it must be set to the best state. Turntable bearings 

theoretically, bearing in operation, with negative clearance operation, the maximum bearing life. But it is very difficult to maintain the best clearance. With the change of the 

conditions of use, the negative clearance of bearings will increase, leading to the bearing life is significantly reduced or have a fever. Therefore, the initial clearance of ring bearing is slightly greater than zero.
