Usual applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives and electronic line shafting. Industries served include Material Managing, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete selection of our servo gearboxes that contain high-end planetary gearboxes, right angle gearboxes, servo worm reducer hypoid gearboxes, cycloid gearboxes in addition to various combinations thereof. All common servo motors could be very easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes guarantee high stiffness and dependable transmission through their particular design. All band gears, world gears and sunlight pinions are case – hardened and ground. This gives an outstanding transmission quality and permits precise positioning tasks.
They can be purchased in nine sizes with reduction ratios from 3:1 to 600:1 and output torque capacities up to 16,227 lb.ft. The output can be provided with a solid shaft or ISO 9409-1 flange, for mounting to rotary or indexing tables, pinion gears, pulleys or other drive components with no need for a coupling. For high precision applications, backlash amounts down to 1 arc-minute can be found. Right-angle and insight shaft versions of the reducers are also available.
Some planetary-geared servo-motors offer additional options. 
For example, oil-flow lubrication and cooling lets products operate continually at up to 3 x the nominal torque and power rating. Oil-cooling also helps to keep the actuator awesome in high-temperature environments. Various other options include explosionproof designs, alternative components and coatings, customized shafts, nonstandard electric motor voltages such as for example 24 or 48 Vdc, special feedback devices, and special electrical connectors to operate with most amplifiers.
This standard range of Precision Planetary Reducers are perfect for use in applications that demand high performance, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo electric motor technology, providing tight integration of the electric motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or customized motors), standard low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless running.
Fewer elements also offer small packaging compared to bolt-on reducers. Bolt-on gear-heads regularly use right-position gears to reduce the distance a reducer extends beyond a machine. Right-position gears, however, require an additional set of bevel gears to help make the convert. These gears boost 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 benefit of a planetary gearhead entirely.
