Abstract
The invention discloses a single-ball universal joint. The structure of the single-ball universal joint comprises a driving shaft fork, a driven shaft fork, a central ball and connecting balls, wherein the driving shaft fork and the driven shaft fork form a rectangular forked structure, and the driving shaft fork and the driven shaft fork are symmetrically arranged in a manner of being perpendicular to each other; the central ball is arranged between the driving shaft fork and the driven shaft fork, four ball grooves in a shape of a spherical crown are formed in the ball surface of the central ball, and the four ball grooves are uniformly distributed on the central ball; one connecting ball is arranged in each ball groove; and ball grooves in a shape of a spherical crown are formed in the inner sides of the fork bodies at the forked opening of the driving shaft fork and the driven shaft fork, and the ball grooves of the driving shaft fork and the driven shaft fork are arranged on the connecting balls in a sleeving manner. The single-ball universal joint has the advantages of being simple in structure and constant in speed.
Description
Technical field
The present invention relates to a kind of universal joint, particularly relate to a kind of single ball universal joint.
Background technique
Traditional universal joint has multiple, but the simple universal joint variable speed of structure, the gimbal structure of constant speed is remarkable.
Summary of the invention
Problem to be solved by this invention is to provide a kind of single ball universal joint, the simple and constant speed of its structure.
In order to overcome the above problems, technological scheme of the present invention is as follows:
A kind of single ball universal joint, its structure comprises initiatively yoke, driven yoke, astrosphere and connection ball; Described active yoke and the rectangular prong like of driven yoke, described active yoke and driven yoke are orthogonal being arranged symmetrically with; Be provided with astrosphere between described active yoke and described driven yoke, the sphere of described astrosphere is provided with four domed ball grooves, and described four ball grooves are evenly distributed on described astrosphere; Connection ball is provided with in described each ball groove; Inner side on the fork body of the prong of described active yoke and described driven yoke is provided with the ball groove of spherical crown shape, and the ball groove of described active yoke and described driven yoke is enclosed within described connection ball.
The invention has the beneficial effects as follows: the simple and constant speed of structure.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the embodiment of the present invention.
