Belt drive and gear drive are two kinds of widely used mechanical transmission, both in the transmission principle there is a clear difference. Today we will compare their strengths and weaknesses, to see which has a longer useful life, which’s more economical!

Transmission principle

The process of gear transmission and the principle of belt drive has a significant difference.

Belt drive amd gear drive

The main drive gear through the multi-stage transmission with a transmission device. The gear train is driven by the double clutch to the counter gear drive. This process creates a torque flow. This unit has a number of coplanar gear sets with many countershaft gears that drive the other gears drive

Advantage :

Gear transmission stable, compact structure, reliable work, can achieve a larger transmission ratio. Transmission efficiency, used in a wide range of power, speed, size. Suitable for large mill (above 6R)

Belt drive amd gear drive

Belt drive easier to understand, the kinetic energy produced by the motor is transmitted to a power transmission mode on the machinery through the pulley, the belt. Its biggest feature is free to change speed, distance transmission, simple structure, easy belt replacement.

Advantage :

simple structure, convenient use and maintenance, stable operation, low noise and buffering vibration absorption effect. Very suitable for Raymond mill(3R-5R) use. When overloaded, the belt will slip on the pulley. Can prevent the damage of fragile parts, play a security role

In summary, gear transmission and belt drive each have their own advantages and disadvantages, need to be selected according to different mill manufacturing design requirements. In contrast, the belt drive relative to the gear rotation, more economical and practical.

Guilin hengda mining machinery used both Belt drive and gear drive. Belt drive for smaller Raymond mill such as GYM9720 ;HD1280;5R4128;HD1620 raymond grinder mill .And gear type used for HD1720;HD2150;HD2500 Super-large Raymond grinding mill. To ensure each mill working at low noise ,low vibration,long-term use without problem.
