Typical applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries served include Material Handling, 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 and also various combinations thereof. All common servo motors could 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, world gears and sun pinions are case – hardened and ground. This gives an outstanding transmission quality and permits 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 solid shaft or ISO 9409-1 flange, for installation to rotary or indexing tables, pinion gears, pulleys or other drive components without the need for a coupling. For high precision applications, backlash amounts down to 1 servo worm reducer arc-minute are available. Right-angle and insight shaft versions of the reducers are also offered.
Some planetary-geared servo-motors offer additional options. For instance, oil-movement lubrication and cooling lets units operate constantly at up to three times the nominal torque and power ranking. Oil-cooling also continues the actuator great in high-temperature environments. Various other options include explosionproof designs, alternative materials and coatings, custom 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 selection of Precision Planetary Reducers are ideal for use in applications that demand powerful, precise positioning and repeatability. These 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 mounting any servo motors (IEC, NEMA, or personalized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless running.
Fewer elements also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads often use right-angle gears to reduce the distance a reducer extends beyond a machine. Right-position gears, however, require an additional group of bevel gears to help make the switch. These gears increase the solution’s size, price, complexity, and total backlash since another mechanism is placed between the load and the electric motor. Usage of beveled gears defeats the advantage of a planetary gearhead entirely.
