With the many industrial precision gearbox gearboxes available today, it’s vital that you match the proper kind of gearbox with the drive, motor, and load. When a machine requires a servosystem (drive and electric motor), the gearbox type is critical for accurate and repeatable motion. Planetary gearboxes fit the bill 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 ratings (typically ranging from someone 
to nine arc-min), and when sized correctly offer a service life of over 20,000 hours with practically no maintenance. Helical planetary gears also provide very calm and better operation as compared to competitive products.
Precision gearboxes are carefully machined to high tolerances – believe clockmaker, not blacksmith. They provide 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, but in many applications it’s advantageous to make use of a gearbox between your motor and load.
One main cause to use a gearbox is torque multiplication. It lets designers make use of smaller servosystems that consumes much less energy. Rather than buying relatively large servodrives and motors, developer can use smaller components, saving space and cash.
Output torque boosts in direct proportion to the gear ratio, and top swiftness of the result shaft decreases. If an application can withstand the reduced speed, a relatively little servosystem can supply high torque.
