Drive pulley provides a driving force for conveyors. Its diameter is usually larger than others pulleys in case to increase the pulley life and traction. According to customers’ requirements, BuMtresD can supply pulleys with hot vulcanized rubber lagging and cold bonded lagging, the lagging can be plain or with grooves. Different patterns of grooves, like herringbone or diamond, is suitable for dirty or wet conditions. A ceramic lagging can enhance the friction between the pulleys and belt. Thus a lagging pulley can effectively improve the operation status of the conveying system and protect the metal pulley from wearing.
The pulley directly was made by large seamless steel. We precisely cut the tube by using the flame cutting machine, and weld the inner pulley disc by using the professional pulley welding machine, and weld the pulley sleeve & disc by using the positioner. We use the large drum lathe process the outside circle, so that it ensures the pulley has the uniform thickness and small pulsation. We chose 45# round steel & sleeve and process the whole shaft so that it ensures shaft concentricity and reduction for the eccentric shaft force. It make sure the pulley move more stable, high quality bearing which is hot charging and bearing block are equipped inner bearing enlargement device, so the bearing can be easily pushed to the bearing position and it avoids the bearing damage from the beating. We need make the eliminating inner stress treatments when the pulley’s withstand forces exceed 80KN and we will make the static balance inspection when the belt speed exceeds 2.5m/s.
Feature of motorized drive conveyor drum pulley for conveyor
1. Steady running, reliable quality and reduce maintenance;
2. Less movement longitudinally, rotating smoothly, extends the life span;
3. Various bearing housing and sealing structure are available for the customers choice;
4. Multipass labyrinthine sealing,preventing the mixed dirt and water immersed;
5. Manufacturing by steel pipe specially for of high precision roller, ensuring the strong load,
low shaking and less noise.
