Regular applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials 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 range of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes along with various combinations thereof. All common servo motors can be quickly set up with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high stiffness and dependable transmission through their particular design. All band gears, world 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 planetary gearbox for servo motor installation to rotary or indexing tables, pinion gears, pulleys or other drive elements without the need for a coupling. For high precision applications, backlash levels right down to 1 arc-minute are available. Right-angle and input shaft versions of these 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 ranking. Oil-cooling also will keep the actuator great in high-temperature environments. Additional options include explosionproof designs, alternative materials and coatings, customized shafts, nonstandard 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 engine technology, providing limited integration of the electric motor to the unit. Design features include installation any servo motors (IEC, NEMA, or personalized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and peaceful running.

Fewer elements also offer small packaging compared to bolt-on reducers. Bolt-on gear-heads often use right-position gears to reduce the length a reducer extends beyond a machine. Right-position gears, however, require an additional group of bevel gears to help make the switch. These gears raise the solution’s size, cost, complexity, and total backlash since another mechanism is placed between the load and the motor. Use of beveled gears defeats the advantage of a planetary gearhead completely.
