With the many commercial gearboxes on the market, it’s important to match the proper type of gearbox with the drive, motor, and load. Whenever a machine needs a servosystem (drive and engine), the gearbox type is crucial for accurate and repeatable motion. Planetary gearboxes suit you perfectly for servo applications.

High-precision helical planetary gearboxes are a great choice for applications that require precision and reliability. Planetary gearboxes have got very low backlash ratings (typically ranging from one to nine arc-min), so when sized correctly offer 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 bundle size and efficiencies of 90% and servo motor gear reducers greater.
Servomotors often drive loads directly with no need for a gearbox, however in many applications it’s beneficial to use a gearbox between your motor and load.

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

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

Gearboxes can also address inertia mismatches. For powerful servosystems — people that have high powerful responses or low overshoot, for example – the ratio between your reflected load inertia and engine inertia should be only practical, ideally under ten-to-one. A precision gearbox reduces the reflected inertia by the square of the reduction ratio. For instance, utilizing a 25:1 gearbox decreases the load’s reflected inertia by a factor of 625, a significant improvement.
