The servo gearboxes PT complete the whole 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 can be easily installed with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high stiffness and dependable transmission through their particular design. All ring gears, planet gears and sun pinions are case – hardened and ground. This provides a superb transmission quality and permits precise positioning tasks.
They are available in nine sizes with decrease 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 mounting to rotary or indexing tables, pinion gears, pulleys or other drive elements with no need for a coupling. For high precision applications, backlash amounts right down to 1 arc-minute are available. Right-angle and insight shaft versions of these reducers are also offered.
Some planetary-geared servo-motors offer additional options. For instance, oil-circulation lubrication and cooling lets units operate constantly at up to three times the nominal torque and power rating. Oil-cooling also continues the actuator awesome in high-temperature environments. Additional options include explosionproof designs, alternative components and coatings, customized shafts, nonstandard motor voltages such as 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 powerful, precise positioning and repeatability. These were specifically developed for make use of with state-of-the-art servo motor technology, providing tight servo worm reducer integration of the motor to the unit. Style features include mounting any servo motors (IEC, NEMA, or customized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency 
and silent running.
Fewer elements also offer compact packaging compared to bolt-on reducers. Bolt-on gear-heads often use right-angle gears to reduce the distance a reducer extends beyond a machine. Right-angle gears, however, require an additional group of bevel gears to make the switch. These gears boost the solution's size, price, complexity, and total backlash since another system is placed between the load and the electric motor. Use of beveled gears defeats the advantage of a planetary gearhead entirely.
