Typical 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 whole selection of our servo gearboxes that consist of high-end planetary gearboxes, right angle gearboxes, hypoid gearboxes, cycloid gearboxes along with various combinations thereof. All common servo motors can be very easily set up with all sizes of our gearboxes. Our PT servo planetary gearboxes ensure high stiffness and dependable transmission through their unique design. All ring gears, planet gears and sun pinions are case – hardened and ground. This provides 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 good shaft or ISO 9409-1 flange, for installation 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 these reducers are also offered.
Some planetary-geared servo-motors offer planetary gearbox for servo motor additional options. For instance, oil-flow lubrication and cooling lets products operate continuously at up to three times the nominal torque and power rating. Oil-cooling also continues the actuator awesome in high-temperature environments. 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 electric connectors to use with most amplifiers.
This standard selection of Precision Planetary Reducers are ideal for use in applications that demand high performance, precise positioning and repeatability. They were specifically developed for make use of with state-of-the-art servo electric motor technology, providing limited integration of the electric motor to the unit. Style features include mounting any servo motors (IEC, NEMA, or personalized motors), regular low backlash, high torsional stiffness, 95 to 97% efficiency and noiseless running.
Fewer elements also offer compact packaging in comparison to bolt-on reducers. Bolt-on gear-heads frequently use right-position gears to reduce the length a reducer extends beyond a machine. Right-position gears, however, require an additional set of bevel gears to make the change. These gears increase the solution’s size, price, complexity, and total backlash since another mechanism is placed between the load and the engine. Usage of beveled gears defeats the benefit of a planetary gearhead altogether.
