Poly V Pulleys

Poly V pulleys:

SSTmachinery offer Poly V Pulleys are the basic type of poly-V-belt pulleys. They are produced in standard series and dimensions of gray cast iron or they are custom made according to drawings or customer requirements.

Their design is based on ISO 9982 and DIN 7867 standards.

The poly v pulleys are usually mounted on shafts using the Taper bush. Only smaller sizes are supplied as a semi-finished product and the bore must be modified before mounting the pulleys on the shafts.

Poly-V Pulley and Belt drives are ideal where you have space restrictions, high ratio or high torque drives. With only one belt, tensioning is easy and you do not have to worry about matching belts. They will also run quieter than timing pulley and chain drives and do not slip like standard V-Pulleys.

Typical applications: robotics hoisting equipment, automotive assembly systems, pallet conveyors, linear positioning, vacuum conveyor belts, & packaging assembly systems.

There are generally five wheels on the belt of the automobile engine, respectively:

1. Crankshaft pulley, the power source is locked, and the belt rotation is provided by this pulley.

2. The water pump pulley rotates to circulate the cooling water inside the engine.

3. The generator pulley rotates to realize the generator rotation and provide supplementary power for the vehicle.

4. The belt pulley of the compressor rotates to realize the operation of the compressor, provide the air conditioner with low-temperature refrigerant, and reduce the temperature in the vehicle.

5. Tensioner pulley, to ensure that the belt works with proper tension.

Crankshaft pulley function:

Drive the water pump, generator and air conditioning pump to work. The water pump is used to ensure the water circulation of the engine to achieve heat dissipation. The generator is used to charge the battery and ensure the normal work of various circuits of the car. The air conditioning pump is the compressor used for the air conditioning system.
