With the many industrial gearboxes available today, it’s vital that you match the proper type of gearbox with the drive, motor, and load. Whenever a machine requires a servosystem (drive and electric motor), the gearbox type is crucial for accurate and repeatable motion. Planetary gearboxes suit you perfectly for servo applications.

High-precision helical planetary gearboxes are an excellent choice for applications that need precision and reliability. Planetary gearboxes have got very low backlash ratings (typically ranging from one to nine arc-min), and when sized correctly provide a service existence of over 20,000 hours with virtually no maintenance. Helical planetary gears also provide very noiseless and more efficient operation as compared to competitive products.

Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They offer power densities that means 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 the motor and load.

One main cause to employ a gearbox is torque multiplication. It lets designers make use of smaller sized precision gearbox servosystems that consumes much less energy. Rather than buying relatively large servodrives and motors, designer can use smaller components, saving space and money.

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