Comparison of gear drive and belt drive
The two axis center distance of belt pulley is larger. The disadvantages are: belt drive pulley drive elastic sliding and skidding, the transmission efficiency is low and can not maintain accurate transmission ratio; pulley transmission circumferential force equally big, pressure contour size and axial ratio of gear transmission; the belt drive belt of short service life. All kinds of machinery and equipment pulley diameter and other dimensions are their own pulleyAccording to the speed ratio, according to the working speed and the speed of the motor is designed.
The characteristics of the belt drive point: pulley transmission energy relaxation load impact; belt drive smooth running, low noise, low vibration; structural belt drive is simple and convenient to adjust; the belt drive pulley for the manufacture and installation of precision gear transmission as strictly; belt drive with overload protection function
Gear drive is characterized by: smooth gear transmission, accurate transmission ratio, reliable work, high efficiency, long life, the use of power, speed and size range. Such as transmission of power from small to several 101000 watts; speed up to 300m/s; gear diameter from a few millimeters to more than 20 meters. However, the manufacture of gears requires specialized equipment, which causes noise
