With the many commercial gearboxes available today, it’s vital that you match the proper type of gearbox with the drive, motor, and load. When a machine requires a servosystem (drive and electric motor), the gearbox type is critical for accurate and repeatable movement. Planetary gearboxes fit the bill for servo applications.

High-precision helical planetary gearboxes are a great choice for applications that need accuracy and reliability. Planetary gearboxes have got very low backlash rankings (typically ranging from someone to nine arc-min), so when sized correctly offer a service existence of over 20,000 hours with virtually no maintenance. Helical planetary gears also provide very silent and better operation when compared with competitive products.

Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They offer power densities that translates to small bundle size and efficiencies of 90% and greater.
Servomotors often drive loads directly without the need for a gearbox, however in many applications it’s advantageous to make use of a gearbox between your motor and load.

One main reason to use a gearbox is torque multiplication. It lets designers make use of smaller sized servosystems that servo motor gear reducers consumes less energy. Instead of buying relatively huge servodrives and motors, developer can use smaller parts, saving space and money.

Output torque improves in direct proportion to the apparatus ratio, and top quickness of the result shaft decreases. If an application can withstand the decreased speed, a relatively small servosystem can supply high torque.
