With the many commercial gearboxes on the market, it’s important to match the proper kind of gearbox with the drive, motor, and load. When a machine needs a servosystem (drive and electric motor), the gearbox type is crucial for accurate and repeatable motion. Planetary gearboxes suit you perfectly for servo applications.
High-precision helical planetary gearboxes are a great choice for applications that need accuracy and reliability. Planetary gearboxes have got very low backlash rankings (typically ranging from one to nine arc-min), so when sized correctly provide a service life of over 20,000 hours with practically no maintenance. Helical planetary gears provide very noiseless and better operation in comparison with competitive products.
Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They offer power densities that means small bundle 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 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 components, saving space and money.
Output torque improves in direct proportion to the apparatus ratio, and top speed of the result shaft decreases. If a credit card applicatoin can withstand the reduced speed, a relatively small servosystem can supply high torque.
Gearboxes can also address inertia mismatches. For high performance servosystems — those with high powerful responses or low overshoot, for example – the ratio between your reflected load inertia and motor inertia should be as low as 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 reduces the load’s reflected inertia by a factor of 625, a significant improvement.
