With the many industrial gearboxes on the market, it’s vital that you match the proper kind of gearbox with the drive, motor, and load. Whenever a machine needs a servosystem (drive and engine), the gearbox type is crucial for accurate and repeatable movement. Planetary gearboxes suit you perfectly for servo applications.
High-precision helical planetary gearboxes are a great choice for applications that need precision and reliability. Planetary gearboxes have got very low backlash rankings (typically ranging from someone 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 noiseless and more efficient operation in comparison with competitive products.
Precision gearboxes are carefully machined to high tolerances – think 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, but in many applications it’s beneficial to make use of a gearbox between the 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, designer can use smaller components, saving space and money.
Output torque increases in direct proportion to the gear ratio, and top velocity of the output shaft decreases. If an application can withstand the decreased speed, a relatively small servosystem can supply high torque.
Gearboxes may also address inertia mismatches. For high performance servosystems — people that have high powerful responses or low overshoot, for instance – the ratio between your reflected load inertia and engine inertia should be only practical, preferably under ten-to-one. A precision gearbox decreases the reflected inertia by the sq . of the reduction ratio. For instance, using a 25:1 gearbox reduces the load’s reflected inertia by one factor of 625, a significant improvement.
