With the many commercial gearboxes available today, it’s vital that you match the proper kind 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 movement. Planetary gearboxes suit you perfectly for servo applications.

High-precision helical planetary gearboxes are an excellent choice for applications that require accuracy and reliability. Planetary gearboxes have got very low backlash ratings (typically ranging from someone to nine arc-min), and 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 – think clockmaker, not blacksmith. They offer power densities that means small package size and efficiencies of 90% and greater.
Servomotors often drive loads directly with no need for a gearbox, however in many applications it’s advantageous to use a gearbox between your motor and load.

One main reason to use a gearbox is torque multiplication. It lets designers use smaller sized servo motor gear reducers servosystems that consumes much less energy. Instead of buying relatively large servodrives and motors, designer can use smaller parts, saving space and cash.

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

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