With the many commercial gearboxes on the market, it’s vital that you 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 critical for accurate and repeatable motion. Planetary gearboxes suit you precision gearbox perfectly for servo applications.
High-precision helical planetary gearboxes are a great choice for applications that require precision 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 noiseless and better operation when compared with competitive products.
Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They offer power densities that translates to small bundle size and efficiencies of 90% and greater.
Servomotors often drive loads directly without the need for a gearbox, but in many applications it’s beneficial to use a gearbox between your motor and load.
One main reason to use a gearbox is torque multiplication. It lets designers make use of smaller sized servosystems that consumes much less energy. Rather than buying relatively huge servodrives and motors, developer can use smaller components, saving space and money.
Output torque increases in direct proportion to the apparatus ratio, and top speed of the output shaft decreases. If an application can withstand the reduced speed, a relatively little servosystem can supply high torque.
