DECELERATOR FOR AUTOMATICALLY BRAKING

摘要

PURPOSE: A decelerator used as an automatic brake is provided to cut down manufacturing expenses, and to assemble and process conveniently by minimizing the volume with simple structure. CONSTITUTION: A planetary gear(10) is assembled with a fixing inner gear(11), and fixed by inserting to a planetary gear supporting shaft(15) formed in a carrier(14). An input shaft(13) is inserted to a fixing groove(16) of the fixing inner gear, and integrally formed with the carrier. The planetary gear is engaged with an output shaft inner gear(12), and the fixing inner gear is installed in a decelerator case. The planetary gear rotates with the output shaft inner gear, and the carrier drives the planetary gear in transmitting force to the input shaft. The output shaft inner gear is rotated with turning the planetary gear along the fixing inner gear. Stability is improved with forming teeth of the planetary gear less than teeth of the fixing inner gear.
