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 motor), the gearbox type is critical for accurate and servo motor gear reducers repeatable motion. Planetary gearboxes suit you perfectly for servo applications.

High-precision helical planetary gearboxes are a great choice for applications that require accuracy and reliability. Planetary gearboxes have got very low backlash rankings (typically ranging from one to nine arc-min), so when sized correctly offer a service life of over 20,000 hours with virtually no maintenance. Helical planetary gears also provide very calm and better 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 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 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 servosystems that consumes less energy. Rather than buying relatively huge servodrives and motors, designer can use smaller components, saving space and cash.

Output torque increases in direct proportion to the apparatus ratio, and top velocity of the output shaft decreases. If a credit card applicatoin can withstand the reduced speed, a relatively small servosystem can supply high torque.

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