precision gearbox

With the many industrial gearboxes on the market, it’s important to match the proper type of gearbox with the drive, motor, and load. Whenever a machine requires 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 an excellent choice for applications that require accuracy and reliability. Planetary gearboxes have very low backlash ratings (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 also provide very peaceful and better operation as compared to competitive products.

Precision gearboxes are carefully machined to high tolerances – think clockmaker, not blacksmith. They offer power densities that translates to 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 make use of a gearbox between the motor and load.

One main cause to employ a gearbox is torque multiplication. It lets designers make use of smaller servosystems that consumes much less energy. Instead of buying relatively large servodrives and motors, developer can use smaller components, saving space and cash.

Output torque raises 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 little servosystem can supply high torque.

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