The use of pulleys to transfer the force resulting from the rotation of the shaft of the power plant on the shaft of the unit, equipment or machine is quite often used in a variety of design schemes. They are a friction wheel equipped with:
- Center hole with or without grooves for mounting on the shaft.
- Teeth or grooves on the outer diameter of the rim to transmit rotation through the belt mounted on them.
They can be made of a wide variety of materials (metal, alloys, plastics and wood), depending on the parameters of the equipment. The ability to manufacture any type of custom-made pulley allows consumers to receive a quality part that meets the required technical parameters even for imported or discontinued domestic equipment.
Selection (ordering) criteria
When placing an order for the manufacture of the required pulley (batch of these parts), it is necessary to know exactly the parameters of their classification. They mainly depend on the type of belt used to transmit rotation:
- Toothed - the rotational movement is carried out due to the engagement of the tooth of the belt with the tooth on the rim of the pulley. The technical indicators of the conformity of the pulley and the belt are the number of teeth, the dimensions of the belt profile, as well as the height (diameter) of the working part of the rim.
- V-ribbed belts - used for special belts characterized by high elasticity and strength at the same time.
- Flat pulleys are the simplest device for flat type belts.
- Round belt or cable pulleys - designed to transmit small forces, such as in car winches.
- CVT pulleys are quite complex but effective parts that allow the operator to change the gear ratio during rotation without affecting the power plant.
You can get more complete information about the possibility of making an individual order for the manufacture of the required type and size of pulleys using the website of a company that provides this type of service using its own high-tech equipment, as well as years of accumulated professional experience.
