Typical applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries offered include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
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 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 reliable transmission through their particular design. All ring gears, world gears and sun pinions are case – hardened and ground. This gives an outstanding transmission quality and allows for precise positioning tasks.
They can be purchased in nine sizes with decrease ratios from 3:1 to 600:1 and output torque capacities up to 16,227 lb.ft. The output can 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 levels right 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 instance, oil-flow lubrication and cooling lets models operate continuously at up to 3 x 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, custom shafts, nonstandard motor voltages such as 24 or 48 Vdc, special feedback products, and special electrical connectors to operate with most amplifiers.
This standard range of Precision Planetary Reducers are ideal for use in applications that demand high performance, precise positioning and repeatability. These were specifically developed for use with state-of-the-art servo motor technology, providing restricted integration of the motor to the unit. Style features include mounting any servo motors (IEC, NEMA, or personalized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and silent running.
Fewer elements also offer planetary gearbox for servo motor compact packaging in comparison to bolt-on reducers. Bolt-on gear-heads often use right-position gears to reduce the length a reducer extends beyond a machine. Right-angle gears, however, require yet another set of bevel gears to help make the switch. These gears increase the solution’s size, price, complexity, and total backlash since another system is placed between the load and the electric motor. Usage of beveled gears defeats the advantage of a planetary gearhead completely.
