Common applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries served include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete 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 easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and dependable transmission through their unique design. All band gears, planet gears and sunlight pinions are case – hardened and ground. This provides an outstanding transmission quality and allows for precise positioning tasks.
They can be purchased 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 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 the reducers are also available.
Some planetary-geared servo-motors offer additional options. For instance, oil-movement lubrication and cooling lets systems operate constantly at up to three times the nominal torque 
and power rating. Oil-cooling also retains the actuator great in high-temperature environments. Other options include planetary gearbox for servo motor explosionproof designs, alternative materials and coatings, custom shafts, nonstandard electric motor voltages such as for example 24 or 48 Vdc, special feedback devices, and special electrical 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 use with state-of-the-art servo motor technology, providing tight integration of the motor to the unit. Design features include installation any servo motors (IEC, NEMA, or personalized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and calm running.
Fewer elements also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads frequently use right-position gears to reduce the length a reducer extends beyond a machine. Right-position gears, however, require an additional set of bevel gears to make the change. These gears raise the solution’s size, cost, complexity, and total backlash since another mechanism is placed between the load and the engine. Usage of beveled gears defeats the benefit of a planetary gearhead completely.
