HPF Hollow Shaft Gear Unit HPF Hollow Shaft Gear Unit 2 Peak torque Standard: <3 arc-min Low Backlash for Life Innovative ring gear automatically adjusts for backlash, ensuring consistent, low backlash for the life of the gearhead. The ring gear design automatically provides the optimum backlash in the planetary gear train and maintains the same low backlash for the life of the gearhead. High Load Capacity Output Bearing A Cross Roller bearing is integrated with the output flange to provide high moment stiffness, high load capacity and precise positioning accuracy. Based on Harmonic Planetary® gearhead design concept, the hollow shaft planetary features the same superior performance and specifications as the HPG line. The large hollow shaft allows cables, pipes, or shafts to pass directly through the axis of rotation, simplifying the design and improving reliability.

Unit Type Hollow Shaft Gear Unit Unit HPF Hollow Shaft Gear HPF Product Sizing & Selection HPF series (Hollow Shaft Type) To fully utilize the excellent performance of the HPF HarmonicPlanetary® gearheads, check your operating conditions and, using the flowchart, select the appropriate size gear for your application. In general, a servo system rarely operates at a continuous load and speed. The input speed, load torque change and a comparatively large torque is applied during start and stop. Unexpected impact torques may also be applied. HPG series (Input Shaft Type) Unit Type Check your...

When impact torque is applied Calculate the average output speed based on the load torque pattern: no av (rpm) no av＝ Make a preliminary model selection with the following conditions. T av = 30.2 Nm ≦ 48 Nm. (HPF-25A-11 is tentatively selected based on the average load torque (see the rating table on page 95) of size 25 and reduction ratio of 11.) Determine a reduction ratio (R) from the maximum output speed (no max) and maximum...
