Example Embodiment

[0038] Specific embodiment one: reference figure 1 Detailed description of this embodiment, the ball mechanism described in this embodiment includes at least one rotating group, the rotating group comprising: a rod rotating connecting part 1, a pitch rotating connecting part 2, a rolling rotating connecting part 3, and Rack 4;

[0039] The rod rotating connecting part 1 and the pitch rotating connecting part 2 are connected in rotation;

[0040] The pitch rotation connection part 2 and the roll rotation connection part 3 are connected by a moving pair, and the moving pair is arc-shaped;

[0041] The rolling connection part 3 and the frame 4 are connected in rotation;

[0042] The axes of the rod rotation connection part 1 and the roll rotation connection part 3 and the arc track axis of the pitch rotation connection part 2 intersect at one point.

Example Embodiment

[0043] Embodiment 2: This embodiment is a further description of Embodiment 1. The difference between this embodiment and Embodiment 1 is that there are multiple rotating groups, and the multiple rotating groups are connected by a connecting mechanism.

Example Embodiment

[0044] Embodiment 3: This embodiment is a further description of Embodiment 2. The difference between this embodiment and Embodiment 2 is that the connecting mechanism is the supporting member 11, and the mechanism is connected to the connecting member 3 by rolling and rotating. Supporting member 11 on. Such as figure 2 with image 3 Shown.

[0045] Each individual new ball sub-mechanism is connected to the supporting member 11 by rolling, forming a freely rotatable connection. Similarly, according to the analysis of the above-mentioned new-type ball sub-mechanisms, in the composite ball sub-mechanism composed of the new-type ball sub-mechanisms, the intersecting points of the axes of the individual new-type ball sub-mechanisms are all coincident to ensure that the center of the movement does not change.

Abstract

The invention discloses a novel ball pair mechanism and a multi-degree-of-freedom composite ball pair joint hinge, and relates to the technical field of transmission mechanisms. The novel ball pair mechanism and the multi-degree-of-freedom composite ball pair joint hinge aim at solving the problems that in the prior art, a ball pair is complex in structure and small in motion range. The novel ballpair mechanism comprises at least one rotating set, wherein each rotating set comprises a rod piece rotating connecting component, a pitching rotating connecting component, a transverse rolling rotating connecting component and a rack; the rod piece rotating connecting components and the pitching rotating connecting components are rotationally connected; the pitching rotating connecting components and the transverse rolling rotating connecting components are connected through moving pairs; the moving pairs are in an arc shape; the transverse rolling rotating connecting components and the racks are rotationally connected; and the axes of the rod piece rotating connecting components, the axes of the transverse rolling rotating connecting components and the axes of the arc tracks of the pitching rotating connecting components intersect at one point. The novel ball pair mechanism is large in motion range, 360-degree motion can be achieved under the ideal condition, and compared with a traditional composite ball pair, the motion space is obviously improved; and each ball pair can independently move without mutual interference, and multiple ball pairs can be stacked.

Description

technical field [0001] The invention relates to the technical field of transmission mechanisms, in particular to a novel ball pair mechanism and a multi-degree-of-freedom compound ball joint joint hinge. Background technique [0002] There must be definite relative motion between the various components in the mechanism. Therefore, the connection of the components must not only make the two components directly contact, but also produce a certain relative movement. This kind of direct contact active connection is called kinematic pair. The spherical kinematic pair, referred to as the ball pair, is a kind of kinematic pair widely used in mechanical systems. Generally speaking, ball pairs are widely used in parallel mechanisms, space mechanisms, new hinge mechanisms, etc. Since the ball pair has three degrees of freedom, the number of components and kinematic pairs in the mechanism can be reduced, thereby greatly simplifying the structure of the mechanism. [0003] The three-...
