servo motor gear reducers

With the many commercial gearboxes on the market, it's important to match the proper kind of servo motor gear reducers gearbox with the drive, motor, and load. When 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 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), and when sized correctly offer a service life of over 20,000 hours with virtually no maintenance. Helical planetary gears provide very calm and better operation when compared 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 greater.
Servomotors often drive loads directly without the need for a gearbox, however in many applications it's beneficial to use a gearbox between the motor and load.

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

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

Gearboxes may also address inertia mismatches. For powerful servosystems — those with high powerful responses or low overshoot, for example – the ratio between the reflected load inertia and motor inertia should be only practical, ideally under ten-to-one. A precision gearbox reduces the reflected inertia by the sq . 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.
