A ribbed or toothed belt is a synchronous belt providing positive power drive.
It guarantees synchronism between the driver pulley speed and the driven pulley speed.
SYNCHRONOUS BELT
The driven pulley speed, or output speed, will be identical to the driver pulley speed, or input speed.
The ribbed belt drives the movement or positioning with a speed ratio of 1.
Poly V belt drive
Its use for power transmission is widespread in industry.
Its ribs are perpendicular to the drive axis. The ribbed belt provides high-power drive in a compact environment.
