Usual applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries served include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete range of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes in addition to various combinations thereof. All common servo motors can be quickly installed with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high stiffness and reliable transmission through their particular design. All band gears, world gears and sun pinions are case – hardened and ground. This gives an outstanding transmission quality and permits precise positioning tasks.

They are available in nine sizes with planetary gearbox for servo motor reduction ratios from 3:1 to 600:1 and output torque capacities up to 16,227 lb.ft. The output can 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, backlash amounts right down to 1 arc-minute can be found. Right-angle and input shaft versions of the reducers are also available.

Some planetary-geared servo-motors offer additional options. For example, oil-flow lubrication and cooling lets units operate consistently at up to three times the nominal torque and power ranking. Oil-cooling also will 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 electrical connectors to operate with most amplifiers.
This standard selection of Precision Planetary Reducers are ideal for use in applications that demand high performance, precise positioning and repeatability. These were specifically developed for make use of with state-of-the-art servo motor technology, providing restricted integration of the motor to the unit. Style features include installation any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and quiet running.

Fewer parts also offer compact packaging compared to bolt-on reducers. Bolt-on gear-heads regularly use right-position gears to reduce the distance a reducer extends beyond a machine. Right-position gears, however, require yet another set of bevel gears to make the turn. These gears raise 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 altogether.
