Normal 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 contain high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes as well as various combinations thereof. All common servo motors can be easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes assure high planetary gearbox for servo motor stiffness and dependable 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 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 installation to rotary or indexing tables, pinion gears, pulleys or other drive elements with no 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 available.
Some planetary-geared servo-motors offer additional options. For instance, oil-flow lubrication and cooling lets units operate consistently at up to three times the nominal torque and power rating. Oil-cooling also helps to keep the actuator cool in high-temperature environments. Other options include explosionproof styles, alternative components and coatings, customized shafts, nonstandard engine voltages such as for example 24 or 48 Vdc, special feedback products, and special electric connectors to use with most amplifiers.
This standard selection of Precision Planetary Reducers are ideal for use in applications that demand powerful, precise positioning and repeatability. These were specifically developed for use with state-of-the-art servo electric motor technology, providing restricted integration of the electric motor to the unit. Design features include mounting any servo motors (IEC, NEMA, or personalized 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 regularly use right-angle gears to reduce the distance a reducer extends beyond a machine. Right-position gears, however, require yet another set of bevel gears to help make the switch. These gears raise the solution’s size, cost, complexity, and total backlash since another system is placed between your load and the engine. Use of beveled gears defeats the benefit of a planetary gearhead altogether.
