Common applications for these reducers include precision rotary axis drives, traveling gantries & planetary gearbox for servo motor columns, material handling axis drives and electronic line shafting. Industries offered include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete selection of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes as well as 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 dependable transmission through their unique design. All ring gears, planet gears and sun pinions are case – hardened and ground. This gives a superb transmission quality and allows for precise positioning tasks.
They are available in nine sizes with decrease ratios from 3:1 to 600:1 and output torque capacities up to 16,227 lb.ft. The output could be provided with a solid shaft or ISO 9409-1 flange, for mounting to rotary or indexing tables, pinion gears, pulleys or other drive elements with no need for a coupling. For high precision applications, backlash levels down to 1 arc-minute can be found. Right-angle and input shaft versions of these reducers are also available.
Some 
planetary-geared servo-motors offer additional options. For example, oil-circulation lubrication and cooling lets units operate continuously at up to three times the nominal torque and power rating. Oil-cooling also maintains the actuator cool in high-temperature environments. Various other options include explosionproof designs, alternative components and coatings, customized shafts, nonstandard electric motor voltages such as 24 or 48 Vdc, special feedback devices, and special electrical connectors to operate with most amplifiers.
This standard selection 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 motor technology, providing limited integration of the motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or personalized 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 length a reducer extends beyond a machine. Right-position gears, however, require yet another group of bevel gears to help make the turn. These gears boost the solution’s size, price, complexity, and total backlash since another system is placed between the load and the engine. Usage of beveled gears defeats the benefit of a planetary gearhead entirely.
