Usual applications for these reducers include precision rotary axis drives, traveling gantries & columns, material handling axis drives and electronic line shafting. Industries offered 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, 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 reliable transmission through their unique design. All band gears, world gears and sunlight pinions are case – hardened and ground. This gives an outstanding transmission quality and allows for precise positioning tasks.
They are available 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 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 servo worm reducer 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 models operate constantly at up to 3 x the nominal torque and power rating. Oil-cooling also helps to keep the actuator awesome in high-temperature environments. Additional options include explosionproof designs, alternative materials 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 powerful, precise positioning and repeatability. They were specifically developed for use with state-of-the-art servo engine technology, providing restricted integration of the electric motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or customized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and peaceful running.
Fewer elements also offer small packaging compared to bolt-on 
reducers. Bolt-on gear-heads frequently use 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 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 advantage of a planetary gearhead completely.
