Regular applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries offered include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete range of our servo gearboxes that contain high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes in addition to various combinations thereof. All common servo motors could be very easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high stiffness and reliable transmission through their unique design. All band gears, planet gears and sun pinions are case – hardened and ground. This provides a superb transmission quality and allows for precise positioning tasks.

They can be purchased in nine sizes with reduction ratios from 3:1 to 600:1 and output torque capacities up to 16,227 lb.ft. The output could be provided with a good shaft or ISO 9409-1 flange, for mounting to rotary or indexing tables, pinion gears, pulleys or other drive components with no need for a coupling. For high precision applications, planetary gearbox for servo motor backlash amounts right down to 1 arc-minute are available. Right-angle and input shaft versions of the reducers are also obtainable.

Some planetary-geared servo-motors offer additional options. For example, oil-flow lubrication and cooling lets units operate constantly at up to three times the nominal torque and power ranking. Oil-cooling also maintains the actuator awesome in high-temperature environments. Additional options include explosionproof designs, alternative components and coatings, custom shafts, nonstandard motor voltages such as 24 or 48 Vdc, special feedback products, and special electric connectors to operate with most amplifiers.
This standard range of Precision Planetary Reducers are ideal for use in applications that demand powerful, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo electric motor technology, providing restricted integration of the electric motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and silent running.

Fewer components also offer small packaging compared to bolt-on reducers. Bolt-on gear-heads frequently use right-angle gears to reduce the distance a reducer extends beyond a machine. Right-position gears, however, require an additional set of bevel gears to help make the change. These gears boost the solution’s size, price, complexity, and total backlash since another system is placed between your load and the motor. Use of beveled gears defeats the benefit of a planetary gearhead completely.
