With the many commercial gearboxes available today, 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 engine), 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 require accuracy and reliability. Planetary gearboxes have got very low backlash rankings (typically ranging from one to nine arc-min), and when sized correctly offer a service lifestyle of over 20,000 hours with practically no maintenance. Helical planetary gears provide very noiseless and better operation when compared with 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 with no need for a gearbox, but in many applications it’s advantageous to make use of a gearbox between the motor and load.

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

Output torque boosts 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 example – the ratio between your reflected load inertia and electric 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, utilizing a 25:1 gearbox reduces the load’s reflected inertia by one factor of 625, a significant improvement.
