Common planetary gearbox for servo motor applications for these reducers include precision rotary axis drives, traveling gantries & columns, materials handling axis drives and electronic line shafting. Industries offered include Material Handling, Automation, Aerospace, Machine Tool and Robotics.
The servo gearboxes PT complete the complete range of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes as well as 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 sun pinions are case – hardened and ground. This provides a superb transmission quality and permits precise positioning tasks.
They can be purchased 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 good shaft or ISO 9409-1 flange, for mounting to rotary or indexing tables, pinion gears, pulleys or other drive elements without the need for a coupling. For high precision applications, backlash amounts down to 1 arc-minute can be found. Right-angle and input shaft versions of the reducers are also offered.
Some planetary-geared servo-motors offer additional options. For instance, oil-flow lubrication and 
cooling lets devices operate constantly at up to three times the nominal torque and power rating. Oil-cooling also will keep the actuator cool in high-temperature environments. Other options include explosionproof designs, alternative materials and coatings, customized shafts, nonstandard electric motor voltages such as for example 24 or 48 Vdc, special feedback products, and special electric connectors to operate with most amplifiers.
This standard selection 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 motor technology, providing limited integration of the engine to the unit. Style features include installation any servo motors (IEC, NEMA, or personalized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless running.
Fewer parts also offer compact packaging in comparison to bolt-on reducers. Bolt-on gear-heads regularly use right-angle gears to reduce the length a reducer extends beyond a machine. Right-angle gears, however, require an additional set of bevel gears to make the switch. These gears increase the solution’s size, cost, complexity, and total backlash since another system is placed between your load and the motor. Usage of beveled gears defeats the benefit of a planetary gearhead altogether.
