Helical gearboxes

Cylindrical gearboxes are manufactured with an output shaft to transmit power from the input shaft to the output shaft, while changing the rotational motion direction, speed and torque. These gearboxes utilize pairs of cylindrical helical gears to facilitate power transmission. This design helps reduce noise and vibration, making cylindrical gearboxes favored in equipment where quiet and smooth operation is crucial. The contact between gear teeth occurs gradually, providing improved load distribution capabilities and a longer service life for the gears. Gearbox housings can be made from various materials, including cast iron and aluminum, to meet specific operational requirements, such as resistance to corrosion or extreme temperatures. Cylindrical gearboxes are used in various industries, including manufacturing, woodworking, conveyors, mixers, grinders, and many other machines. This type of gearbox is the second most popular after worm gearboxes.
