Common applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives and digital line shafting. Industries served include Material Managing, 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 along with 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 reliable transmission through their unique design. All ring gears, world 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 solid 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 right down to 1 arc-minute are available. Right-angle and insight shaft versions of these reducers are also available.
Some planetary-geared servo-motors offer additional options. For example, oil-stream lubrication and cooling lets models operate continually at up to 3 x the nominal torque and power rating. Oil-cooling also retains the actuator awesome in high-temperature environments. Various other options include explosionproof styles, alternative components and coatings, customized shafts, nonstandard motor voltages such as for example 24 or 48 Vdc, special feedback products, and special electrical connectors to use with most amplifiers.
This standard selection of Precision Planetary Reducers are perfect for use in applications that demand powerful, precise positioning and repeatability. These were specifically developed for use with state-of-the-art servo motor technology, providing restricted 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 peaceful running.
Fewer elements also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads frequently use servo worm reducer right-position 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 turn. These gears raise 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 altogether.
