Title:
REDUCTION GEAR
Document Type and Number:
Japanese Patent JPS5854256
Kind Code:
A
Abstract:
PURPOSE:To secure a high reduction gear ratio without producing any backlash despite a simple constitution, by pressing a flake rotary plate, which is incorporated with an output shaft as one body, to an unrotatable slide body having a conical surface continuously in the circumferential direction. CONSTITUTION:When a roller 5, which is fitted with some play to a roller shaft 18, is given revolution by dint of the input of a gear 18, a flake rotary plate 8 being secured to an output shaft 10 comes into contact with a slide body 3 at two points and thereby the contact positions move in the circumferential direction. On the other hand, rotation of the slide body 3 is locked whereby it is mobable only in an axial direction. Since the total local length of contact points of the slide body 3 minutely differs from that of contact points of the flake rotary plate 8, the output shaft 10 is rotated with a high reduction gear ratio.
