Problems solved by technology

However, when the volume of the reducer is constant, the transmission ratio of the RV reducer increases with the number of pin gear teeth, and the size of the single cycloidal tooth and the pin tooth pin becomes smaller, which affects the further improvement of the reducer's load capacity.
In addition, the RV reducer requires high machining accuracy and high cost, which restricts its promotion and application. In particular, it is very difficult to meet the machining accuracy of two eccentric shafts arranged with a difference of 180 degrees, and its accuracy directly affects the transmission of the reducer. precision and efficiency
The large speed ratio of the RV reducer comes from its planetary reduction transmission and cycloidal pinwheel reduction transmission. The series connection of the reducer doubles, which cannot meet the needs of small size and high-efficiency load-carrying of the reducer for robots.

Abstract

The invention relates to an inner and outer tooth form meshing gear reducer comprising a first-level reducing mechanism and a second-level reducing mechanism. The first-level reducing mechanism comprises an eccentric wheel (101), a first turning bearing(5), an outer-meshing curve wheel (7) and a gear pin (8); the gear pin is fixed on a first support (9) and externally meshes with the outer-meshing curve wheel (7). The second-level reducing mechanism comprises an eccentric driving wheel (14), a second turning bearing (13) sleeved on the eccentric driving wheel (14), an outer-meshing curve wheel (11), and an output plate (16) in linkage with an output shaft (20). The outer-meshing curve wheel (11) is sleeved on the second turning bearing (13) and internally meshes with the gear pin (8). The eccentric driving wheel (14) is in linkage with the outer-meshing curve wheel (7) through a pin (6), and the outer-meshing curve wheel (11) is in linkage with the output plate (16) through a driving pin (12). The inner and outer tooth form meshing gear reducer has the advantages of few tooth numbers, high speed ratio, small size, high load bearing, high efficiency and long service life, and is especially applicable to reducers by industrial robots.

Description

technical field [0001] The invention relates to an industrial reducer with small tooth difference, belonging to the technical field of reducers. This invention is funded by the "National High Technology Research and Development Program (863 Program)". Background technique [0002] The reducer is a general-purpose machine that is widely used in industrial and agricultural production. With the development of science and technology, especially the development needs of automation products such as industrial robots, reducers have begun to develop in the direction of small size, high load capacity, high efficiency and long life. [0003] There are two main types of reducers used in the field of robotics: harmonic reducers and cycloidal reducers. At present, Japan's Harmonic Drive high-performance harmonic reducer and Japan's Nabtesco Teijin Seiki Company's new reducer Rotary Vector (RV for short) developed in the 1980s occupy a dominant position in the robot field. The forme...
