Embodiment Construction

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a transmission mechanism and a robot. The transmission mechanism comprises a first driving part, a transmission assembly, a first driven part and an encoder; the first driving part drives the first driven part through the transmission assembly, and the encoder is used for detecting the displacement of the first driven part; the transmission assembly comprises a first toothedpart fixed to the first driving part, a second toothed part fixed to the first driven part, an elastic part and a pressing toothed part for pressing the first toothed part and the second toothed part, and the first toothed part and the second toothed part are meshed with each other; one end of the elastic part is connected to the pressing toothed part, the other end of the elastic part is connected to the first toothed part, and the pressing toothed part is meshed with the second toothed part; or the other end of the elastic part is connected to the second toothed part, and the pressing toothed part is meshed with the first toothed part. In the transmission mechanism and the robot, when the first toothed part stops moving, the second toothed part stops moving at the same time, and the influence of transmission clearance is avoided.

Description

technical field [0001] The invention belongs to the technical field of robots, and more specifically relates to a transmission mechanism and a robot. Background technique [0002] With the continuous development of robot technology, the functions of robots are constantly improving, and the requirements for robots are getting higher and higher. The accuracy of robot joint activities is an important embodiment of the motion accuracy of the robot's execution end. Because the mechanical transmission is adopted in the joints of the robot, such as gear transmission, belt transmission and so on. When the robot is used for a long time, the transmission parts will inevitably wear out and produce transmission gaps. For example, after the gears are worn, the backlash between the gears increases. After the driving gear stops rotating, the driven gear will rotate a certain angle (the transmission gap brought by the backlash) before it can stop. As a result, when the execution end of t...
