Usual 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 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 could be quickly installed with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and reliable transmission through their particular design. All ring gears, world gears and sunlight pinions are case – hardened and ground. This gives a superb 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 elements without the need for a coupling. For high precision applications, backlash levels down to 1 arc-minute are available. Right-angle and input shaft versions of these reducers are also offered.
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, servo worm reducer 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 elements also offer small packaging compared to bolt-on reducers. Bolt-on gear-heads regularly use right-angle 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 turn. These gears increase the solution’s size, price, complexity, and total backlash since another mechanism is placed between the load and the engine. Usage of beveled gears defeats the advantage of a planetary gearhead completely.
