With the many commercial gearboxes available today, it’s important to match the proper type of gearbox 
with the drive, motor, and load. Whenever a machine requires a servosystem (drive and engine), the gearbox type is crucial for accurate and repeatable movement. Planetary gearboxes fit the bill for servo applications.
High-precision helical planetary gearboxes are an excellent choice for applications that need precision and reliability. Planetary gearboxes have very low backlash rankings (typically ranging from one to nine arc-min), and when sized correctly provide a service existence of over 20,000 hours with practically no maintenance. Helical planetary gears provide very tranquil and better operation as compared to competitive products.
Precision gearboxes are carefully machined to high servo motor gear reducers 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 use a gearbox between your motor and load.
One main reason to employ 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 parts, saving space and cash.
Output torque boosts in direct proportion to the apparatus ratio, and top swiftness of the result shaft decreases. If an application can withstand the reduced speed, a relatively small servosystem can supply high torque.
Gearboxes can also address inertia mismatches. For powerful servosystems — people that have high powerful responses or low overshoot, for instance – the ratio between your reflected load inertia and motor inertia should be as low as practical, ideally under ten-to-one. A precision gearbox decreases the reflected inertia by the sq . of the decrease ratio. For instance, using a 25:1 gearbox reduces the load’s reflected inertia by one factor of 625, a substantial improvement.
