Problems solved by technology

The mechanical arm is one of the most widely used mechanical structures, but most of the mechanical arms have complex structures and require multiple driving sources
In many occasions, the requirements for the degree of freedom of the manipulator are not very high. At this time, the use of a manipulator with multiple degrees of freedom and complex mechanisms will outweigh the gain.

Abstract

The invention relates to an iso-curvature bent mechanical arm based on gear drive. The arm comprises n drive shafts, wherein n is natural number except zero; and n drive shafts are articulated to be the mechanical arm in series by n-1 universal joints and are connected with n-1 bevel gear drive pair mechanisms to realize the iso-curvature bent drive. The mechanical arm has simple structure, almost uses the same parts, and can complete the requirement of iso-curvature bent drive only with single drive source.

Description

technical field [0001] The invention relates to a mechanical arm mechanism, in particular to an equal-curvature bending mechanical arm based on gear transmission. technical background [0002] With the continuous maturity and development of robot technology, the application of robots is not limited to the industrial field, and more and more robots are used in different fields such as humanoid robots and toy robots. The mechanical arm is one of the most widely used mechanical structures, but most of the mechanical arms have complex structures and require multiple driving sources. In many occasions, the requirements for the degree of freedom of the manipulator are not very high, and at this time, the use of a manipulator with multiple degrees of freedom and complex mechanisms will outweigh the gain. Contents of the invention [0003] The object of the present invention is to solve the defects of the prior art, and provide a constant-curvature bending mechanical arm, which h...
