Standard applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries offered include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the whole range of our servo gearboxes that contain high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, planetary gearboxes for mixercycloid gearboxes as well as various combinations thereof. All common servo motors can be quickly installed with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and reliable transmission through their particular design. All band gears, world gears and sunlight pinions are case – hardened and ground. This provides a superb transmission quality and permits 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 can be provided with a solid shaft or ISO 9409-1 flange, for installation to rotary or indexing tables, pinion gears, pulleys or other drive elements with no need for a coupling. For high precision applications, planetary gearbox for servo motor backlash amounts down to 1 arc-minute can be found. Right-angle and input shaft versions of the reducers are also offered.

Some planetary-geared servo-motors offer additional options. For instance, oil-flow lubrication and cooling lets devices operate continually at up to 3 x the nominal torque and power rating. Oil-cooling also helps to keep the actuator cool in high-temperature environments. Other options include explosionproof styles, alternative materials and coatings, custom shafts, nonstandard electric motor voltages such as 24 or 48 Vdc, special feedback products, and special electric connectors to use with most amplifiers.
This standard range of Precision Planetary Reducers are ideal for use in applications that demand high performance, precise positioning and repeatability. They were specifically developed for make use of with state-of-the-art servo motor technology, providing tight integration of the engine to the unit. Design features include installation any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless running.

Fewer components also offer compact packaging compared to bolt-on reducers. Bolt-on gear-heads often 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 make the convert. These gears increase the solution’s size, cost, complexity, and total backlash since another system is placed between the load and the engine. Usage of beveled gears defeats the advantage of a planetary gearhead completely.
