Standard applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and digital line shafting. Industries offered include Material Managing, 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 could be 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 sun pinions are case – hardened and ground. This gives an outstanding 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 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 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 the reducers are also obtainable.
Some planetary-geared servo-motors offer additional options. For instance, oil-flow lubrication and cooling lets devices operate continually at up to three times the nominal torque and power rating. Oil-cooling also keeps the actuator cool in high-temperature environments. Additional options include explosionproof styles, alternative materials and coatings, customized shafts, nonstandard electric motor voltages such as for example 24 or 48 Vdc, special feedback gadgets, and special electrical connectors to use with most amplifiers.
This standard range of Precision Planetary Reducers are perfect for use in applications that demand high servo worm reducer performance, precise positioning and repeatability. These were specifically developed for use with state-of-the-art servo electric 
motor technology, providing limited integration of the electric 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 peaceful running.
Fewer parts also offer small packaging in comparison 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 switch. These gears increase the solution’s size, cost, complexity, and total backlash since another system is placed between the load and the engine. Use of beveled gears defeats the advantage of a planetary gearhead entirely.
