Variable speed belt gear motors speed reducer gearbox
Variable speed belt gear motors are space-saving, continuously adjustable drives. In the standard version the central adjustment is made with a hand wheel. Unlike inverter operation the motor power remains constant and the torque increases if the speed of the motor drops.
The variable speed gear unit housing has a proven symmetrical design. The adjusting pulleys have a wedge shaped symmetrical cross section with low mass. The shape of the pulleys ensures uniform flank pressure and therefore high power transmission, even at high belt speed.
The result is optimal control behaviour with uniform distribution of forces and minimal energy consumption.
