Flexible intelligent precision transmission device

Abstract

The invention relates to a flexible intelligent precision transmission device and provides a transmission device with high transmission stability. The transmission device comprises an eccentric input shaft, a supporting disk, a fixed gear module, an output module, two outer gears and a flexible intelligent connecting module, wherein the eccentric input shaft comprises two eccentric sections with the same eccentric distance and opposite eccentric directions; an inner gear is arranged on the fixed gear module; the fixed gear module and the eccentric input shaft are coaxially arranged; the supporting disk is arranged between the eccentric input shaft and the fixed gear module and can rotate; connecting long holes are formed in the two outer gears along the radial direction; the two outer gears are arranged on the two eccentric sections correspondingly and can rotate; each of the two outer gears and the inner gear are meshed to form a meshing pair with less tooth difference; the output module is arranged on the eccentric input shaft and can rotate; and the flexible intelligent connecting module passes through the two connecting long holes to connect the supporting disk with the output module. The flexible intelligent precision transmission device can be widely applied in the fields of high-end equipment, such as intelligent robots, high-grade numerical control machine tools, aerospace and the like.

Description

technical field [0001] The invention relates to a transmission device, in particular to a flexible intelligent transmission device for deceleration using the principle of meshing with few tooth differences. Background technique [0002] At present, various transmission parts and systems at home and abroad cannot meet the major needs of modern high-end equipment in special environments such as high and low temperature alternation, oil shortage, and heavy loads, and the increasing development of modern high-end equipment, especially when meeting high precision requirements. Key technical performance requirements such as high reliability and long life. Due to the manufacturing and assembly errors of various parts in the robot transmission system and the coupling effect of multiple factors such as materials, structures, working conditions, loads, time, and environment during operation, the transmission mechanism inevitably fluctuates. Lubrication failure, "jamming" or even "jam...

Problems solved by technology

However, the eccentric shafts of the two types of reducers have only one eccentricity. When the gears revolve around the eccentric shafts, centrifugal force will be generated, which will affect the stability of operation and limit the upper limit of the speed of each gear of the reducer to a certain extent. At the same time, the elastic body does not have shape memory characteristics. , cannot adapt to some special environments and extreme working conditions, so there is room for further improvement of these two reducers
