Flat Belts are utilized in various
applications, especially for driving machines in industries. Flat belts
are made of various materials like rubber, leather etc. In some cases
they are reinforced with metal, textiles and fibers. Rubber is a popular
material used in the making of flat belts. These belts are highly
convenient and reliable in operation and installation and are used in
high-speed, low-power applications. They are generally used in textile
manufacturing machines, paper making machines and conveyors. They have
durable surface coatings which provide anti-static properties and
withstand high tension and cost-effective.
Classifications of flat belts
Based on their design, rubber flat belts are classified as follows:
- Stretch
- Semi-stretch
- Non-stretch belts
Types of rubber used in making rubber flat belts
- Urethane rubber
- Neoprene elastomer
- Hypalon
- Ethylene Propylene Diene Monomer (EPM, EPDM)
- Silicone Rubber (SiR)
Types of Rubber Flat Belts
- Small woven endless belts: Suitable for
applications in which less vibration is produced near the driven
pulley. These belts are designed as elastic belts, semi-elastic
belts and non-stretch belts.
- Higher power flat belts: They are made up of
abrasion-resistant rubber. This eliminates the high tension applied
to grip pulleys.
Buying Tips
Following are the specifications of Flat Belts:
- Working Load: The maximum weight or mass
that a belt can support which is expressed in pounds.
- Length: This is the linear distance
measured from one end of the belt to the other and expressed in
inches or millimeters.
- Weight: This refers to the heaviness of the
flat belt and expressed in kilograms or pounds.
- Thickness: This is the distance between two
surfaces of a rubber flat belt and expressed in millimeters or
inches.
