What is a pulley

The pulley is a small wheel with grooves on the periphery and capable of rotating around an axis. A simple machine that can rotate around the central axis, which is composed of a grooved disc and a flexible cable (rope, tape, steel cable, chain, etc.) across the disc, is called a pulley.


The role of gearbox

Generally, the speed of the wind wheel of the gearbox is very low, far less than the speed required by the generator to generate electricity. It must be realized by the speed-increasing effect of the gear pair of the gearbox, so the gearbox is also called a speed-increasing box.


Basic information of pulley

Classification and number: fixed pulley, movable pulley, pulley block. Material: wooden pulley, steel pulley and engineering plastic pulley, which can be made of various materials according to actual requirements.


The gearbox has the following functions: accelerate and decelerate, change the transmission direction, change the torque, clutch function, and distribute power.

Advantages of  pulle drive

Advantages of pulley drive

The advantages of belt pulley transmission are: belt pulley transmission can alleviate load impact; belt pulley transmission runs smoothly, with low noise and low vibration; belt pulley transmission has a simple structure and easy adjustment; belt pulley transmission is not as strict as mesh transmission for the manufacturing and installation accuracy of pulleys; pulley transmission It has the function of overload protection; the adjustment range of the center distance of the two shafts driven by the belt pulley is large.
