Hoist belt and pulley design?
A type of belt, according to the need of power and small pulley speed, mostly choose B type V ordinary belt. Next to the V belt type selection according to the primary small round reference diameter, V belt, belt wheel speed datum diameter.After determining the belt type, the reference diameter is calculated according to the bonding relationship of the belt. When calculating, it is necessary to consider the factors such as the angle of the package, the length of the belt and the basic rated power of the single V belt.
Hoist motors and reducers are linked together by belts, and pulleys and belts play a vital role in the transmission of power. Pulley and belt selection takes into account the load on the hoist and the time it takes to operate every day.
Most of the V pulleys used in engineering are made of gray cast iron. When the belt speed is relatively high, the cast steel or steel welded structure can be adopted. If you need to transfer power is relatively small, you can use aluminum alloy or plastic belt pulley.Hoist belt wheel has three parts, wheel hub and spoke, because the spoke structure is a belt wheel, and can be divided into four types: with datum diameter less than or equal to 2.5-3 and less than or equal to the diameter of solid base plate, a 300 mm hole plate and spoke.
