Preparation data
Matters needing attention in operation
In the operation, there should be no grease on the surface of the triangle belt. Otherwise remove it to
reduce the skidding between the triangle belt and belt wheel to the lowest.
Function:
the drive disk, clutch and the driven wheel compose the steeples speeder. The torque between the dive
disk and the driven wheel is transmitted through the triangle belt.
