Typical applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries offered include Material Handling, 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 and also various combinations thereof. All common servo motors can be quickly set up with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and reliable transmission through their unique design. All ring gears, planet gears and sun pinions are case – hardened and ground. This provides a superb transmission quality and allows for precise positioning tasks.

They are available 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 solid shaft or ISO 9409-1 flange, for mounting to rotary or indexing tables, pinion gears, pulleys or other drive components without the need for a coupling. For high precision applications, backlash levels right down to 1 arc-minute are available. Right-angle and insight shaft versions of the reducers are also obtainable.

Some planetary-geared servo-motors offer additional options. For example, oil-stream lubrication and cooling lets systems operate continuously at up to 3 x the nominal torque and power rating. Oil-cooling also helps to keep the actuator great in high-temperature environments. Other options include explosionproof designs, alternative components and coatings, custom shafts, nonstandard electric motor voltages such as 24 or 48 Vdc, special feedback products, and special electrical connectors to operate 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 use with state-of-the-art servo motor technology, providing restricted integration of the electric motor to the unit. Style features include installation any servo motors (IEC, NEMA, or personalized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and calm running.

Fewer elements also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads frequently use right-position gears to reduce the length a reducer extends beyond a machine. Right-position gears, however, require an additional set of bevel gears to make the change. These gears raise the solution’s size, cost, complexity, and total backlash since another servo worm reducer mechanism is placed between the load and the engine. Usage of beveled gears defeats the benefit of a planetary gearhead completely.
