precision gearbox

With the many industrial gearboxes available today, it’s vital that you match the proper type of gearbox with the drive, motor, and load. Whenever a machine needs a servosystem (drive and motor), 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 accuracy and reliability. Planetary gearboxes possess very low backlash rankings (typically ranging from one to nine arc-min), so when sized correctly provide a service existence of over 20,000 hours with virtually no maintenance. Helical planetary gears also provide very calm and more efficient operation as compared to competitive products.

Precision gearboxes are carefully machined to high tolerances – think clockmaker, not blacksmith. They provide 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 beneficial to use a gearbox between your motor and load.

One main reason to employ a gearbox is torque multiplication. It lets designers make use of smaller servosystems that consumes less energy. Instead of buying relatively huge servodrives and motors, developer can use smaller elements, saving space and money.

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

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