Title:
SPEED REDUCTION DEVICE WITH END FACE CAN
Document Type and Number:
Japanese Patent JPS61112854
Kind Code:
A
Abstract:
PURPOSE:To make a power transmission device compact and light and enable self lock by providing annular cams between two rotary discs and rotating both the rotary discs through rotating bodies to reduce speed in the power transmission device of various industrial machines. CONSTITUTION:An input shaft 1 and an output shaft 2 are rotatably supported on a coaxial line and rotary discs 6, 7 are fixed to the input shaft 1 and the output shaft 2 so as to be placed oppositely with each other with a constant distance, and annular cams 8, 9 corresponding to their opposite faces are projected. The cam face 8a of the input side annular cam 8 is formed on tan inclined cam face inclining gently in the same direction continuously, and the cam face 9a of the output side annular cam 9 is formed in wave shape in the peripheral direction where mountainous unevenness is much continued. The contour shape of the cam thread of cam faces 8a, 9a is set by a diameter of a steel ball 11 of an intermediate body and the number of the balls and the balls are sequentially displaced in the axial direction and speed is reduced.
