It is used to change the running direction of the conveyor belt or increase the wrapping angle of the conveyor belt on the transmission roller, and the roller adopts smooth glue surface.
The roller shaft shall be forged and NDT, and the defect report shall be provided. The allowable torque and allowable resultant force should meet the design requirements.
The roller shaft at maximum load conditions, the deflection of shaft between the bearing roller Pigang regardless of the condition of <L/2500. Proper transition fillet should be set at the cross section of the shaft to avoid stress concentration.
