Reducer with bevel gear and cycloid in large transmission ratio for ore grinding machine

Abstract

The invention relates to the technical field of reducing the speed of an ore grinding machine. A reducer with a bevel gear and a cycloid in a large transmission ratio for an ore grinding machine is characterized by comprising a bevel gear pair and a cycloid transmission part; the bevel gear pair comprises driving and driven bevel gears; in the cycloid transmission part, (A) needle pin semi-buried holes are uniformly distributed on a needle gear shell, and the needle pins without sleeves are movably matched with the semi-buried holes; (B) a W output mechanism is composed of an output shaft, a column pin, a uniform loading disc and an annular plate; two sides of the W output mechanism are supported on an inner hole of a machine body and the outer circle of a flange in an end cover through bearings; in four single-eccentric bearings, the phase difference between the first bearing and the second bearing and the phase difference between the third bearing and the fourth bearing are 180 DEG and the phase of the second bearing is same as that of the third bearing. In the invention, the reducer has the beneficial effects as follows: (1) the bearing capability is improved by 2-3 times; (2) the length of the axial direction is reduced by 45-55% and the cost is reduced by 40-50%; (3) the reversed installation service life of a cycloid gear is doubled; and (4) the inertia force and the inertia moment are completely balanced in theory when the reducer is operated.
