Round Belts

Round belts are mostly utilized for powered roller conveyors, line shaft or live roller conveyors, and power transmission applications. One advantage is that users can easily purchase them from any source of circular belts, cut them to length, and then combine them to fit the pulley system.

These belts do not require a belt tensioner because they are intended to stretch. This circular belt minimizes surface contact with the component, making the conveyors for which it is used appropriately for drying or lowering product contamination. Round belts are often constructed from polymer materials, which exhibit excellent chemical and abrasion resistance and do not require tensioning or tracking modifications.

A round belt is appropriate for clean rooms because it lacks fibers. Light- to heavy-duty power transmission belts include round and o-ring belts. Other names for these goods include endless-drive belts and endless-circular belts. Round belts are cylindrical lengths of material that can be solid or hollow. They require stretching or elongation to function and rely on friction to keep in touch with the belt pulleys.

Types of Round Belts

Round belts come in various polymers and designs with various strengths, elasticities, and transmissions. Nitrile rubber is suitable for procedures involving oils and alcohols since it is resistant to petroleum hydrocarbons. The second material is neoprene, which can sustain a wide range of temperature ranges and is extremely durable due to its resistance to twisting and fracture. The third type is polyurethane, which includes various circular urethane belt varieties. These are typically resistant to abrasion. Rubber, the fourth and final category, offers distinct elastic qualities.

Buna-N often referred to as nitrile rubber, is a synthetic rubber copolymer made of butadiene and acrylonitrile. It works well in applications requiring lubricants, hydraulic fluids, and alcohols because it is resistant to petroleum hydrocarbons. The recommended operating range for Buna-N is around -30° to 275° F.

Neoprene is a synthetic rubber made by polymerizing chloroprene giving the rubber great flexibility and strong chemical stability. It functions effectively in contact with oils and chemicals like nitrile rubber. Neoprene can function successfully at temperatures ranging from -45° to 230° F and is renowned for resisting twisting and breaking damage.

A wide range of polyurethane polymers provides outstanding elongation, recovery, and toughness properties. They are also flexible and resilient to abrasion.

Common Problems Encountered With Round Belts

• The belt rips off at the tail pulley.

  Reason: Belt swerving across the loading region and around the tail pulley

  Solution: Install training idlers (pulleys that guide a belt) on the return side before the tail pulley as a solution.

  Reason: Material spills and accumulation

  Solution: Improvements can be made to loading and transfer circumstances by cleaning equipment and regular maintenance.

  Reason: Idlers or pulleys that are not aligned with the belt's middle line

  Solution: Adjust idlers in the affected area as a solution.

• The belt rips off at the head pulley.

  Reason: Worn-out pulley lagging

  Solution: Replace the pulley lagging as a solution.

  Reason: Material spills and accumulation

  Solution: Improvements can be made to loading and transfer circumstances by cleaning equipment and regular maintenance.

  Reason: Idlers or pulleys that are not aligned with the belt's middle line

  Solution: Adjust idlers in the affected area as a solution.

Applications of Round Belts

Round belts are cylindrical solid or hollow material lengths that use friction to maintain contact with belt pulleys. Therefore, they require stretching to function. These circular belts are frequently employed in power transmission applications for machines used in packing, printing, photocopying, transporting, and imaging.

Conveyors can be set up differently from the straight conveyor by using round belts to transmit power. For example, round belt conveyors can spin 90 degrees (a quarter turn) round belts to turn a shaft whose axis is rotated a quarter turn away from the drive shaft and supply power transfer for straight conveyors.
