V-Belt
The Earth India Company offers V-Belts designed for efficient and dependable power transmission across a wide range of industrial machinery and equipment. V-belts transmit power through frictional contact between the belt sidewalls and the grooves of a matching V-pulley (sheave). Their trapezoidal cross-section creates a wedging action inside the pulley groove, helping provide effective power transmission in a compact drive arrangement. Available in multiple sections, lengths and constructions, V-belts can be selected according to the required power, speed, pulley dimensions and operating conditions.
CORE COMPOUNDING
EPDM/Neoprene compound with high-strength polyester cords
Overview & Engineering Design
Designed for Dependable Power Transmission V-belt drives are widely used because of their simple design, reliable operation and ability to transmit power efficiently between rotating shafts.
Core Product Features
Efficient Power Transmission
Wedging action within the pulley groove provides effective frictional grip.
Compact Drive Design
Suitable for transmitting power within relatively compact machinery layouts.
Smooth & Quiet Operation
Flexible belt construction helps absorb vibration and shock loads.
Reliable Performance
Designed for continuous industrial power-transmission applications.
No Lubrication Required
Provides clean and practical operation compared with lubricated drive systems.
Easy Installation & Maintenance
Straightforward belt replacement when the drive is properly designed and accessible.
Multiple Sections & Lengths
Available across various V-belt profiles to meet different drive requirements.
Suitable for Multi-Belt Drives
Multiple matched belts can be used together where higher power transmission is required.
V-Belt Construction
A V-belt consists of several components designed to provide strength, flexibility and reliable engagement with the pulley.
Tensile Member
High-strength tensile cords carry the primary operating load and help control belt elongation during operation.
Compression Rubber
The rubber section below the tensile member provides flexibility and supports the belt as it bends around the pulley.
Cushion Rubber
The surrounding rubber compound supports and protects the tensile cords while maintaining the required belt structure.
Protective Fabric / Cover
Depending on the V-belt construction, an outer fabric layer may provide additional protection against wear and environmental exposure.
How V-Belt Drives Work & Configurations
The V-shaped belt runs inside a corresponding pulley groove. As tension is applied, the belt sidewalls contact the pulley groove and create a wedging action.
Friction & Wedge Action
This friction between the belt and pulley allows rotational power to be transferred from the drive pulley to the driven pulley.
Importance of Correct Tension
A belt that is too loose may slip, while excessive tension can increase loads on the belt, bearings and shafts.
Single & Multiple V-Belt Drives
Single-Belt Drives
A single V-belt can be used where the required power transmission falls within the capacity of the selected belt and drive configuration.
Multiple-Belt Drives
For higher-power applications, multiple V-belts may operate side by side on a multi-groove pulley. For such drives, correctly matched belts are important so that the operating load is distributed as evenly as possible between the belts.
V-Belt Sections & Profiles
V-belts are available in different cross-sectional profiles according to the required power, pulley size and drive configuration. Common profiles include:
The correct profile must always be matched with the corresponding pulley groove. Availability should be confirmed according to the required belt size and construction.
Typical Applications
V-belts are commonly used in:
The appropriate belt section and construction depend on the power-transmission requirements of the equipment.
Understanding V-Belt Specifications
A V-belt is generally identified using its:
For example, B-66 indicates a B-section V-belt with a 66 inch nominal length designation. V-belt length may be specified using different reference systems depending on the manufacturer and belt standard. Therefore, when replacing an existing belt, the complete belt marking and manufacturer reference should be provided.
