servo motor gear reducers

With the many commercial gearboxes on the market, it’s important to match the proper kind of gearbox with the drive, motor, and load. Whenever a machine requires a servosystem (drive and electric motor), the gearbox type is servo motor gear reducers critical for accurate and repeatable movement. Planetary gearboxes fit the bill 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 ratings (typically ranging from someone to nine arc-min), so when sized correctly provide a service lifestyle of over 20,000 hours with virtually no maintenance. Helical planetary gears also provide very calm and better operation in comparison with competitive products.

Precision gearboxes are carefully machined to high tolerances – think clockmaker, not blacksmith. They provide power densities that means small package size and efficiencies of 90% and greater.
Servomotors often drive loads directly without the need for a gearbox, however in many applications it’s advantageous to use a gearbox between your motor and load.

One main cause to employ a gearbox is torque multiplication. It lets designers use smaller servosystems that consumes less energy. Rather than buying relatively huge servodrives and motors, designer can use smaller components, saving space and cash.

Output torque improves in direct proportion to the apparatus ratio, and top rate of the result shaft decreases. If a credit card applicatoin can withstand the decreased speed, a relatively little servosystem can supply high torque.

Gearboxes may also address inertia mismatches. For high performance servosystems — people that have high dynamic responses or low overshoot, for instance – the ratio between the reflected load inertia and engine inertia should be as low as practical, ideally under ten-to-one. A precision gearbox reduces the reflected inertia by the square of the decrease ratio. For instance, utilizing a 25:1 gearbox decreases the load’s reflected inertia by one factor of 625, a substantial improvement.
