Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, in t...

Abstract

The invention provides a rope transmission mechanism, including: a steel wire rope, a connecting device and a tensioning device. The steel wire rope is sequentially wound on the driving wheel and the driven wheel along a certain direction to form a steel traveler. The driving wheel pulls the driven wheel through the steel wire rope. Rotation, the connecting device includes: a driving wheel connecting device and a driven wheel connecting device, the driving wheel connecting device is arranged on the driving wheel and connects the driving wheel with the steel wire rope, and the driven wheel connecting device is arranged on the driven wheel and connects the driven wheel with the steel wire rope, The tensioning device is arranged between the driving wheel and the driven wheel and is connected with the steel wire rope, and the tensioning device is used for tensioning the steel wire rope. The single-rope transmission in the embodiment of the present invention, under the premise of a narrow installation space, improves the space utilization rate, increases the selected diameter of the rope, and thus increases the transmission rigidity. The continuous tensioning mechanism is easy to adjust and effectively tensions the upper and lower sections of the wire rope synchronously, ensuring the coordination of movement and the stability of force transmission.

Description

technical field [0001] The invention relates to the technical field of a joint transmission mechanism of a multi-joint manipulator, in particular to a rope transmission mechanism and a rope transmission mechanism of a manipulator. Background technique [0002] Multi-degree-of-freedom humanoid robots are equipped with arms and dexterous hands with bionic joints. Unlike industrial manipulators, bionic dexterous hands have relatively sufficient space to design motion mechanisms. Due to the limitation of bionic hand shape and space structure, it is difficult for the current bionic dexterous hand to achieve precise control of fingers and sufficient gripping force. [0003] The existing similar schemes have the following problems: 1. The number of steel wire ropes is usually two, and the installation and maintenance are relatively complicated; 2. The rope end fixing structure and tensioning mechanism are complicated, and the size of the rope end locking parts is relatively large d...
