Regular applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives and digital line shafting. Industries served include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the whole 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 can 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 sunlight 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 can be provided with a good shaft or ISO 9409-1 flange, for mounting 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 are available. Right-angle and input shaft versions of the reducers are also obtainable.

Some planetary-geared servo-motors offer additional options. For instance, oil-flow lubrication and cooling lets systems operate constantly at up to 3 x the nominal torque and power rating. Oil-cooling also retains the actuator cool in high-temperature environments. Additional options include explosionproof designs, alternative materials and coatings, customized shafts, nonstandard engine voltages such as 24 or 48 Vdc, special feedback devices, and special electric connectors to use with most amplifiers.
This standard range of Precision Planetary Reducers are perfect for use in applications that demand powerful, 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. Style features include installation any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and silent running.

Fewer components also offer compact packaging in comparison to bolt-on reducers. Bolt-on gear-heads regularly use right-angle gears to reduce the distance a reducer extends beyond a machine. Right-angle gears, servo worm reducer however, require an additional group of bevel gears to make the switch. These gears boost the solution’s size, cost, complexity, and total backlash since another system is placed between the load and the electric motor. Usage of beveled gears defeats the benefit of a planetary gearhead entirely.
