With the many industrial gearboxes available today, it’s important to match the proper kind of gearbox with the drive, motor, and load. When a machine needs a servosystem (drive and engine), the gearbox type is crucial for accurate and repeatable motion. Planetary gearboxes fit the bill for servo applications.

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

Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They provide power densities that translates to small bundle size and efficiencies of 90% and greater.
Servomotors often drive loads directly with no need for a gearbox, but 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 servo motor gear reducers smaller sized servosystems that consumes much less energy. Rather than buying relatively huge servodrives and motors, designer can use smaller components, saving space and money.

Output torque improves in direct proportion to the gear ratio, and top swiftness of the output shaft decreases. If a credit card applicatoin can withstand the decreased speed, a relatively little servosystem can supply high torque.

Gearboxes can also address inertia mismatches. For high performance servosystems — those with high dynamic responses or low overshoot, for instance – the ratio between your reflected load inertia and electric motor inertia should be only practical, preferably under ten-to-one. A precision gearbox decreases the reflected inertia by the square of the reduction ratio. For instance, using a 25:1 gearbox reduces the load’s reflected inertia by one factor of 625, a substantial improvement.
