With the many industrial gearboxes on the market, it’s vital that you match the proper kind of gearbox with the drive, motor, and load. When a machine needs a servosystem (drive and motor), the gearbox type is critical 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 possess very low backlash rankings (servo motor gear reducers typically ranging from someone to nine arc-min), so when sized correctly offer a service existence of over 20,000 hours with practically no maintenance. Helical planetary gears provide very quiet and more efficient operation when compared with competitive products.

Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They offer 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 make use of a gearbox between your motor and load.

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

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

Gearboxes may also address inertia mismatches. For high performance servosystems — those with high dynamic responses or low overshoot, for example – the ratio between the reflected load inertia and engine inertia should be only practical, preferably 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.
