Abstract

The invention discloses a precision cycloidal-pin wheel planetary transmission device which comprises a machine base, a power input shaft, an eccentric bushing provided with two off centers, a cycloidal wheel I, a cycloidal wheel II, a dowel pin for cycloidal wheels, a power output shaft, a wheel spider I, a wheel spider II and two sets of pin gears that are respectively arranged on the wheel spider I and the wheel spider II; one end of the dowel pin for cycloidal wheels is fixedly arranged on a flange of the power output shaft and the other end is inserted into an isotonic pin hole of the cycloidal wheel I and the cycloidal wheel II to form a pin type output mechanism; the direction of a tooth outline on which the cycloidal wheel I and a pin gear I are meshed and the direction of a tooth outline on which the cycloidal wheel II and a pin gear II are meshed are reverse. The precision cycloidal-pin wheel planetary transmission device of the invention can eliminate or reduce tooth clearance during the transmission process, thereby improving transmission efficiency, reducing vibration and noise and prolonging service life; the relative position of the two wheel spiders in a circumferential direction is adjustable, so that meshed gap and return difference can be controlled effectively and more options are available when shaping the tooth outline of the teeth of the cycloidal wheels.

Description

technical field

[0001] The invention relates to a cycloidal pinwheel transmission device, in particular to a precision cycloidal pinwheel planetary transmission device. Background technique

[0002] Cycloidal pinwheel planetary reduction mechanism is a novel transmission mechanism that adopts the principle of planetary transmission with small tooth difference and cycloidal pin-tooth meshing. Because of the advantages of large transmission ratio, compact structure, high efficiency, stable operation and long life, it is widely used in textile printing and dyeing, light industry food, metallurgy and mining, petrochemical industry, lifting transportation and engineering machinery and other fields. The entire transmission device of the cycloid pinwheel deceleration planetary mechanism can be divided into three parts: the input part, the deceleration part and the output part, specifically including the eccentric sleeve, the eccentric sleeve is equipped with the arm bearing, the cy...
