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

High-precision helical planetary gearboxes are an excellent choice for applications that need accuracy and reliability. Planetary gearboxes have very low backlash rankings (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 provide very tranquil and more efficient operation in comparison with competitive products.

Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They provide power densities that means small package 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 use a gearbox between the motor and load.

One main reason to use a gearbox is torque multiplication. It lets designers use smaller servosystems that consumes less energy. Instead of buying relatively large servodrives and motors, developer can use smaller elements, saving space and cash.

Output torque increases in direct proportion to the gear ratio, and top acceleration of the output shaft decreases. If an application can withstand the reduced speed, a relatively little servosystem can supply high torque.

Gearboxes may also address inertia mismatches. For high performance servosystems — people that have high powerful responses or low overshoot, for example – the ratio between the reflected load inertia and motor inertia should be only practical, preferably under ten-to-one. A precision gearbox decreases the reflected inertia by the sq . of the decrease ratio. For instance, using a 25:1 gearbox decreases the load’s reflected inertia by one factor of 625, a substantial improvement.
