Abstract
A novel universal joint mechanism has one or two pin shafts which are respectively mounted in holes of a convex spherical face head transmission rod and a concave spherical face transmission rod in a penetrating way; two connecting rods are respectively hinged with pin shafts from one sides of the convex spherical face head transmission rod and the concave spherical face transmission rod; and a convex spherical face of the convex spherical face head transmission rod and the concave spherical face of the concave spherical face transmission rod are combined together.
Description
Technical field:
The utility model relates to a kind of universal joint mechanism, and particularly a kind of novel universal saves mechanism, belongs to the driving parts technical field.
Background technique:
Universal joint is a kind of common mechanical connection part, and at present, universal joint structurally all is the structure of standard; That is: all there is cross one another criss-cross joint to be formed by connecting, though the universal joint of this normal structure has the advantage of reliable in function, but, because structure is comparatively complicated, there is the defective that cost is higher, manufacturing process is comparatively complicated, simultaneously, owing to the space that the joint part of universal joint is shared is bigger, inconvenience is installed under the less occasion in some spaces.
The model utility content:
The purpose of this utility model is: provide a kind of novel universal to save mechanism, overcome the defective that the existing cost of gimbal structure is higher, manufacturing process is comparatively complicated of existing standard; Simultaneously, also be for the gimbal structure that overcomes existing standard existing: the shared space of joint part is big, be unfavorable for the defective of installing under less space situations.
The utility model realizes that the technological scheme that above-mentioned purpose adopted is: a kind of novel universal saves mechanism, it is by universal joint mechanism one or two bearing pin to be arranged, two bearing pins are installed in the hole of protruding sphere head drive link and concave spherical surface drive link with connecting respectively, two connecting rods are hinged from a side and the bearing pin of protruding sphere head drive link and concave spherical surface drive link respectively, and the protruding sphere and the concave spherical surface of protruding sphere head drive link and concave spherical surface drive link combine.
Beneficial effect: the utility model is owing to adopt such scheme, so, the utlity model has simple in structure, cost is less, joint part takes up room less, can be conveniently install in less space situations, the existing cost of gimbal structure that overcomes existing standard is higher, manufacturing process gimbal structure comparatively complicated and existing standard is existing: the shared space of joint part is big, be unfavorable for the defective of installing under less space situations.
Description of drawings:
Fig. 1 is a structure principle chart of the present utility model;
Shown in the figure: 1, concave spherical surface drive link; 2, protruding sphere head drive link; 3, bearing pin; 4, connecting rod; A, protruding sphere; B, concave spherical surface.
Embodiment:
Universal joint mechanism has one or two bearing pin (3), two bearing pins (3) are installed in respectively in the hole of protruding sphere head drive link (2) and concave spherical surface drive link (1) with connecting, two connecting rods (4) are hinged with a side and the bearing pin (3) of concave spherical surface drive link (1) from protruding sphere head drive link (2) respectively, and protruding sphere head drive link (2) combines with concave spherical surface (b) with the protruding sphere (a) of concave spherical surface drive link (1).
