Embodiment Construction

[0015] As shown in the figure, the present invention includes an eccentric shaft 1, and the eccentric part of the eccentric shaft 1 is connected to the cycloid wheel through the arm bearing 2. There are multiple eccentric positions that are staggered. The cycloidal wheels outside each eccentric position are divided into two groups: the reverse cycloidal wheel 3 and the forward cycloidal wheel 4. The reverse cycloidal wheel 3 and the forward cycloidal wheel 4 have different numbers of teeth and are set The connection hole 5, the reverse cycloid wheel 3 and the forward cycloid wheel 4 can also be designed as a cycloid wheel group consisting of a plurality of cycloid wheels, and each row of cycloid wheels in each cycloid wheel group is staggered by 360 degrees / n, n is the row number. The pin gear housing is divided into a stationary pin gear housing 6 and an output pin gear housing 7. The reverse cycloidal wheel 3 cooperates with the stationary pin tooth pin 8 fixed on the stati...

Abstract

The invention relates to a complex precise cycloidal speed reducer, which comprises an eccentric shaft, wherein the eccentric parts of the eccentric shaft are connected with cycloidal gears through turning arm bearings, the cycloidal gears are matched with pin tooth pins fixed on pin tooth shells, the eccentric shaft is provided with a plurality of staggered eccentric positions, the cycloidal gears outside the eccentric positions are divided into a group of negative cycloidal gears and a group of positive cycloidal gears, the negative cycloidal gears and the positive cycloidal gears have different tooth number and are provided with connecting transmission holes, the pin tooth shells are divided into static pin tooth shells and output pin tooth shells, the negative cycloidal gears are matched with the static pin tooth pins fixed on the static pin tooth shells, the positive cycloidal gears are matched with the follow-up pin tooth pins fixed on the output pin tooth shells, the eccentric shaft is connected with a gearwheel, and the gearwheel is engaged with an input shaft gear. By composite design of a primary involute planetary gear transmission and cycloidal pin wheel epicyclic gear train, the complex precise cycloidal speed reducer has the advantages of high precision, high efficiency, high rigidity, high bearing and long service life and is particularly suitable to be used in a heavy-duty industrial robot.

Description

technical field [0001] The invention relates to a compound precision cycloid reducer. Background technique [0002] At present, the reducers in heavy-duty industrial robots generally use the Rotate Vector (RV) reducer of Nabtesco Teijin Seiki Co., Ltd. of Japan and the high-performance harmonic reducer of Harmonic Drive of Japan. [0003] Since the transmission of the harmonic reducer realizes the speed conversion and power transmission through the radial elastic deformation of the thin-walled flexible gear, its bearing capacity and transmission stiffness are relatively low, and the flexible gear is also prone to fatigue damage due to periodic deformation. It is mainly used for precision transmission systems with medium and light loads, but it is actually not suitable for precision reduction transmissions for heavy-duty industrial robots. [0004] The RV reducer (Rotate Vector Reducer) of Teijin Seiki Co., Ltd. is composed of a first-stage planetary gear transmission and a ...
