Ultra-high speed drive and gear box combination for small or micro motor, has gear box whose design, material and manufacturing method are adapted for reduction of rotation speed of motor in region of less power ratings

摘要

The combination has a gear box whose design, material and manufacturing method are adapted for reduction of rotation speed of an electric motor from 150 revolutions per minute (rpm) to 10 rpm in a region of less power ratings such as 10 kilowatts. A sun wheel (5) is surrounded by planetary gears (6) that are supported by hydrostatic- or aero-static bearing. The sun wheel is connected to input and output shafts (2, 3) through clutch elements made of resilient material. A self-adjusting centrifugal plastic component is operated in connection with the gear box.
