Normal applications for these reducers include precision rotary axis drives, traveling gantries & 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 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 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 an outstanding transmission quality and permits precise positioning tasks.

They can be purchased in nine sizes with reduction ratios from 3:1 to 600:1 and result torque capacities up to 16,227 lb.ft. The output could be provided with a good shaft or ISO 9409-1 flange, for installation 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 levels right down to 1 arc-minute can be found. Right-angle and insight shaft versions of these reducers are also available.

Some planetary-geared servo-motors offer additional options. For example, oil-stream lubrication and cooling lets systems operate continually at up to three times the nominal torque and power rating. Oil-cooling also will keep the actuator cool in high-temperature environments. Other options include explosionproof styles, alternative components and coatings, custom shafts, nonstandard engine voltages such as 24 or 48 Vdc, special feedback gadgets, and special electrical connectors to use with most amplifiers.
This standard selection of Precision Planetary Reducers are perfect 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 limited integration of the motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or personalized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and tranquil running.

Fewer components also offer compact packaging compared 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 yet another set of bevel gears to make the switch. These gears increase the solution’s size, cost, 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 entirely.
