Usual applications for these reducers include precision rotary axis 
drives, traveling gantries & columns, material handling axis drives and digital line shafting. Industries served include Material Handling, 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 in addition to 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 dependable planetary gearbox for servo motor transmission through their unique design. All ring gears, planet gears and sun pinions are case – hardened and ground. This provides a superb transmission quality and allows for 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 right down to 1 arc-minute are available. Right-angle and input shaft versions of these reducers are also offered.
Some planetary-geared servo-motors offer additional options. For example, oil-flow lubrication and cooling lets products operate continually at up to three times the nominal torque and power ranking. Oil-cooling also keeps the actuator great in high-temperature environments. Various other options include explosionproof designs, alternative components and coatings, custom shafts, nonstandard motor voltages such as 24 or 48 Vdc, special feedback products, and special electric connectors to operate with most amplifiers.
This standard selection 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 engine to the unit. Style features include mounting any servo motors (IEC, NEMA, or customized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and calm running.
Fewer elements also offer small packaging in comparison to bolt-on reducers. Bolt-on gear-heads regularly use right-angle gears to reduce the distance a reducer extends beyond a machine. Right-angle gears, however, require an additional group of bevel gears to make the convert. These gears increase the solution’s size, price, complexity, and total backlash since another mechanism is placed between your load and the electric motor. Usage of beveled gears defeats the advantage of a planetary gearhead entirely.
