FAQ
We've compiled the most frequently asked questions by customers
What is a transmission belt?
A transmission belt is a mechanical component that transfers power between two pulley shafts. It transmits power from the driving pulley to the driven pulley through friction or meshing force, enabling power transmission in mechanical equipment.
- Timing belt: Achieves precise transmission through tooth profile
- V-belt: Provides strong friction through wedge-shaped cross-section
- Flat belt: Suitable for high-speed light-load applications
- Multi-rib belt: Combines advantages of V-belts and flat belts

Transmission belt between two pulley shafts
This is the basic definition of a transmission belt. A belt drive system consists of three main components: the driving pulley, the driven pulley, and the transmission belt. The driving pulley connects to the power source, the driven pulley connects to the load, and the belt transmits the power.
- Driving pulley: Connects to motor or engine
- Driven pulley: Connects to working machinery
- Tension pulley: Adjusts belt tension
- Guide pulley: Changes belt running direction
Top global V-belt brands?
World-renowned V-belt brands include: Gates, Optibelt, Dayco, Megadyne, PIX, etc. These brands lead in quality, technological innovation, and market share.
- Gates - USA, world's largest belt manufacturer
- Optibelt - Germany, expert in high-end industrial belts
- Dayco - Italy, leader in automotive and industrial belts
- Megadyne - Italy, provider of innovative transmission solutions

How to calculate belt tension?
Belt tension calculation considers multiple factors: transmitted power, pulley diameter, belt speed, friction coefficient, etc. The basic formula is: T1/T2 = e^(μα), where T1 and T2 are tight-side and slack-side tensions, μ is friction coefficient, and α is wrap angle.
- Initial tension: Pre-tension during installation
- Working tension: Actual tension during operation
- Maximum tension: Allowable maximum tension value
- Tension measurement: Using tension meter

What is the service life of transmission belts?
The service life of transmission belts depends on multiple factors: working environment, load conditions, maintenance, etc. Generally, industrial belts last 1-3 years, while automotive belts last 60,000-100,000 kilometers.
- Environmental factors: temperature, humidity, chemical corrosion
- Load factors: power level, impact loads
- Maintenance factors: regular inspection, timely adjustment
- Quality factors: material quality, manufacturing process

What are the applications of rubber belts?
Rubber belts are widely used in various industries: automotive (engine accessory drives), textile (spinning and weaving), food (conveying and packaging), agricultural machinery (harvesting and seeding), etc.
- Automotive: AC compressors, generators, water pumps
- Industrial equipment: fans, pumps, compressors
- Agricultural machinery: tractors, harvesters, seeders
- Household appliances: washing machines, dryers, vacuum cleaners
What is a drive pulley?
A drive pulley is the wheel in a transmission system that connects to the power source, typically mounted on the output shaft of a motor or engine. It transmits power to the driven pulley via the belt, enabling power transfer and speed variation.
- Material selection: cast iron, steel, aluminum alloy
- Surface treatment: zinc plating, blackening, anodizing
- Groove design: standard profiles like A, B, C types
- Dynamic balancing: required for high-speed operation

What types of belts are used in the automotive industry?
The automotive industry primarily uses these belt types: multi-rib belts (serpentine belts), timing belts, V-belts, and flat belts. Each type has specific applications and technical requirements.
- Multi-rib belts: Engine accessory drives (AC, alternator, power steering)
- Timing belts: Engine timing systems (camshaft, balance shaft)
- V-belts: Older vehicle models for fan and alternator drives
- Flat belts: Light-duty applications in special cases
