Normal applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries offered include Material Handling, 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 and also various combinations thereof. All common servo motors could be very easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and dependable planetary gearbox for servo motor transmission through their unique design. All band gears, planet gears and sun 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 reduction ratios from 3:1 to 600:1 and result torque capacities up to 16,227 lb.ft. The output can 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 amounts down to 1 arc-minute are available. Right-angle and insight shaft versions of the reducers are also obtainable.
Some planetary-geared servo-motors offer additional options. For example, oil-stream lubrication and cooling lets models operate constantly at up to three times the nominal torque and power rating. Oil-cooling also retains the actuator cool in high-temperature environments. Various other options include explosionproof designs, alternative components and coatings, custom shafts, nonstandard electric motor voltages such as 24 or 48 Vdc, special feedback devices, and special electrical connectors to operate with most amplifiers.
This standard selection 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 limited integration of the engine to the unit. Design features include mounting 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 compact packaging in comparison to bolt-on reducers. Bolt-on gear-heads often use right-position gears to reduce the space a reducer extends beyond a machine. Right-angle gears, however, require an additional set of bevel gears to make the change. These gears increase the solution’s size, cost, complexity, and total backlash since another mechanism is placed between your load and the electric motor. Usage of beveled gears defeats the advantage of a planetary gearhead completely.
