2results about How to "Improve stiffness performance" patented technology

This invention provides a drive device for a continuum robot, comprising a base; multiple fixed pulleys and spaced rope perforation plates; a variable stiffness mechanism supported on the base and located between adjacent rope perforation plates, which has M variable stiffness cams arranged along a common first axis. Each variable stiffness cam changes the tension of the corresponding drive rope after passing through the fixed pulleys by changing its own radius; multiple cam mechanism assemblies are respectively arranged between two adjacent rope perforation plates, and each cam mechanism assembly has M drive cams arranged along a common second axis. Each drive cam has a follower on its upper part, and each drive rope passes through the top of a corresponding follower. During the rotation of the drive cam, the bottom end of the follower makes rolling contact with the top end of the drive cam, and the follower moves radially along the drive cam by changing the radius of the drive cam itself, thereby changing the length of the drive rope. This invention can reduce the number of drive motors, simplify control, and improve the stiffness of the continuum robot.

The utility model belongs to vehicle engineering technical field, concretely is a kind of armored vehicle turret posture control mechanism, including front cover;The front cover end portion is rigidly connected with shell;The front cover end portion is rigidly connected with back cover;The shell lateral wall is equipped with aviation plug;The input shaft is rotatably connected in the middle part of the front cover and back cover, and the input shaft outer wall is equipped with rotating handle;Its characterized in that: the shell inner wall is rigidly connected with boss;Multiple sets of connecting holes are arranged in the middle part of the shell;The middle part of the shell is equipped with mounting hole, and plug is installed in the inner wall of mounting hole;Multiple sets of first through holes are arranged in the bottom of the shell;The shell inner part is three functional areas, uses electric signal as the feedback mode of turret posture control mechanism, removes the transmission and the large amount of mechanical transmission components, such as speed reduction mechanism, etc. in the traditional structure using gear, and the present mechanism uses modularization package, so it is small and exquisite compact.
