Embodiment 1

[0041] In the first embodiment, the movement section 1 is the hole 1 provided on the inner end surface of the upper casing and the track groove 1 provided on the positive side of the cycloid disk, and the movement section 2 is the hole 2 arranged on the inner end surface of the lower casing and the opposite side of the cycloid disk. The provided track groove 2 and the speed reducer provided with eight rollers will be described below as examples.

[0042] Such as Figures 1 to 9 As shown, the single crank cycloid reducer of the present invention is connected with the input device, which includes:

[0043] Upper shell 5.1 and lower shell 5.2;

[0044] an input shaft 1 connected to the input device, the input shaft 1 being a crankshaft;

[0045] The output mechanism one 3.1 installed between the input shaft 1 and the inside of the upper housing 5.1 through the bearing one 2 and the bearing two 4, the output mechanism one installed between the input shaft 1 and the inside of the...

Embodiment 2

[0054] The difference between the present embodiment and the first embodiment is only that the movement zone 1 is the track groove 1 set on the inner end surface of the upper shell and the hole 1 set on the positive side of the cycloid disk, and the movement zone 2 is the hole set on the inner end surface of the lower shell Two and the track groove two arranged on the opposite side of the cycloidal disk, other structures are consistent with the first embodiment.

Embodiment 3

[0056]The only difference between this embodiment and Embodiment 1 is that the movement zone 1 is the hole 1 provided on the inner end surface of the upper shell and the track groove 1 set on the front side of the cycloid disk, and the movement zone 2 is the track set on the inner end surface of the lower shell Groove 2 and the hole 2 provided on the opposite side of the cycloid disc, other structures are consistent with the first embodiment.

Abstract

The present invention provides a mono-crankshaft cycloid speed reducer. The speed reducer comprises a housing; an input shaft connected with input equipment, wherein and the input shaft is a crankshaft; an output mechanism mounted between the input shaft and the interior of the housing by using a bearing I and a bearing II; a cycloid pan positioned in the housing, wherein the cycloid pan is sleeved on an eccentric part of the input shaft; and at least two rolling shafts, wherein each of the rolling shafts is connected with the output mechanism and is inserted on the cycloid pan. Balls and a movement space for the balls are arranged between the cycloid pan and the interior of the housing; the movement space is holes and track grooves disposed between an end surface in the housing and a side surface of the cycloid pan. The mono-crankshaft cycloid speed reducer of the present invention is compact in structure, stable in rotation and high in reliability; the aims of simplifying an internal structure of the speed reducer and reducing a weight and a size of the speed reducer are achieved while transmission efficiency and a speed reduction ratio of the speed reducer are improved, thereby reducing production costs of the speed reducer. The mono-crankshaft cycloid speed reducer is especially suitable for use as a power transmission mechanism on lightly-loaded mechanical equipment.

Description

technical field [0001] The present invention relates to the technical field of mechanical transmission reduction, more specifically, to a speed reducer. Background technique [0002] The reducer plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. The reducer is a relatively precise machine. The purpose of using it is to reduce the speed and increase the torque. Therefore, the application range of the reducer is quite wide. The reducer is mainly used in lifting (crane), mining (vibrating screen), metallurgy, papermaking, construction (mixer), chemical industry, textile, light industry and other industries. It can be seen in the transmission system of various machinery, from ships, automobiles, locomotives, heavy machinery used in construction, processing machinery and automated production equipment used in the machinery industry, to common household appliances in daily life, Clocks and more. Its appli...
