The gear layout of Planetary Gearheads is like a solar system, with multiple planetary gears rotating around the central sun gear. These Planetary Gearheads are surrounded by a ring gear, whose teeth are inward, forming the outer boundary of the planetary gear set.The following information describes our TallMan Robotics Planetary GearheadsYou can see our PGFR High Precision Angle Disc Output Type in this picture table, technnical parameter as follows:High Precision Angle Disc Output TypePGFRPMC tests components while manufacturing. Our final quality control happens right before packing. We pack each planetary gearhead in an inner box, then place that box inside a plywood case. This method guarantees safe delivery over long distances.FAQs about Precision planetary gear reducerWhat is the difference between single-stage and two-stage planetary reducers? A single-stage unit delivers ratios from 3:1 to 10:1 with lower backlash and higher efficiency — typically 97%. A two-stage unit stacks two gear sets to reach ratios from 9:1 to 100:1 but adds backlash at the second mesh and drops efficiency to around 94%. Use single-stage wherever ratio allows.How do I match a planetary reducer to a servo motor? Confirm the gearbox input shaft diameter and motor output shaft diameter match. Check that the gearbox rated input speed exceeds the motor maximum RPM. Verify the motor flange bolt circle matches the gearbox input flange. Finally, confirm peak input torque — motor stall torque — stays below the gearbox maximum input torque rating.What is the difference between a planetary reducer and a worm gear reducer? A planetary reducer delivers 94–97% efficiency, low backlash, and high radial load capacity. A worm gear reducer tops out at 70–85% efficiency, self-locks under back-drive load, and suits low-speed high-torque applications where efficiency loss is acceptable. Servo-driven positioning axes always use planetary; worm gear suits manual or low-duty conveyor drives.Can a precision planetary reducer handle radial and axial loads on the output shaft? Yes. Output shafts run on tapered roller or angular contact bearings designed to carry combined radial and axial loads simultaneously. Check the manufacturer’s radial load diagram — allowable radial load drops as the load application point moves further from the output flange face. Apply loads as close to the flange as possible.You are welcome to watch more projects or visit our website to check other series or load down e-catalogues for further technical data.
