Working principle of hydraulic retaining wheel of rotary kiln
Although there is no big fault in the hydraulic system, poor treatment may also cause kiln shutdown and production reduction. Analysis of the reasons for the failure of the hydraulic wheel system in rotary kiln:
The retaining wheel is improperly installed and the surface contact is poor
When installing the retaining wheel, the center line of the retaining wheel is required to coincide with the longitudinal center line of the kiln body; Only in this way, the pure rolling friction between the wheel belt and the retaining wheel surface is ideal. Once the center line of the retaining wheel deviates greatly from the longitudinal center line of the kiln body, the friction force in the upward and downward directions will be generated on the surface of the retaining wheel, resulting in the displacement of the retaining wheel, the fracture of the upper gland bolt under excessive stress, or even the failure of the whole retaining wheel. When the retaining wheel is close to the rotary direction of the kiln body, the rotation of the wheel belt will produce downward friction on the surface of the retaining wheel, so that the thrust bearing at the bottom is overstressed and fails.
Rotary kiln, on the other hand, usually some slope when installation requirements, so the hydraulic gear wheel base also have corresponding installation Angle, such gear wheel and belting leather on the height direction of contact to reach more than 90%, and once the Angle deviation is bigger, the contact surface will appear only in the upper or lower would be less than 50% of the area, thus affecting shaft bending distance; Torque and other stress conditions cause shaft failure; The wheel belt and the retaining wheel surface due to uneven processing or wear will cause bad meshing, resulting in impact damage to the shaft.
