Abstract
The invention discloses a compact and minitype universal joint which consists of a ball joint, a rotary arm, a central pin shaft, a pin nail and a concave ball joint, wherein the end part of the ball joint is of a ball-shaped structure; the central position of a ball body is provided with an opening groove B; the rotary arm is articulated in the opening groove B by a central pin shaft, and can swing in the opening groove B around the central pin shaft; the end part of the concave ball joint is of an indent spherical structure; the concave ball joint is installed on the ball body at the end part of the ball joint through the indent spherical surface at the end part of the concave ball joint; the concave ball joint is articulated at two ends of the rotary arm through the indent concave spherical surface at the end part of the concave ball joint by the pin nail; and the concave ball joint has degree of freedom swinging around the pin nail. The compact and minitype universal joint provided by the invention has the advantages of simple structure, smaller volume and lower cost, and the universal joint can be suitable for requirements of minitype or micro mechanical transmission.
Description
Technical field
The present invention relates to a kind of universal joint, particularly a kind of compactness, miniature universal joint belong to the mechanical parts technical field.
Background technique
Universal joint generally is used in the situation that need change in the spatial position between two transmission shafts.At present, universal joint structurally generally is that cross axle is hinged forms by two joints, and not only structure is comparatively complicated for it, simultaneously, also exists overall structure bigger, so, exist cost higher, and the defective on less machinery, used of not suiting.
Summary of the invention
The objective of the invention is to: a kind of compactness, miniature universal joint are provided, overcome that the existing existing structure of universal joint is comparatively complicated, cost is higher, and be unfavorable for the defective on small-sized machine, used.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of compactness, miniature universal joint; It is made up of bulb joint, pivoted arm, central pin shaft, pin and recessed ball-joint; It is characterized in that: end, described bulb joint is a spheroidal structure, and the central plane position of spheroid has opening slot B along end, bulb joint, and described pivoted arm is hinged in the opening slot B in bulb joint with central pin shaft; Described central pin shaft is installed along the sphere diameter position in bulb, bulb joint; And perpendicular with the bi-side of opening slot B, described pivoted arm can be swung in opening slot B around central pin shaft, and the end of described recessed ball-joint is the spheric structure of indent; The spherical diameter of indent is with sphere diameter forms the relation of Spielpassung along end, bulb joint; Recessed ball-joint is installed on the spheroid of end, bulb joint through the sphere of the indent of its end, and pin is connected on the two ends of pivoted arm with recessed ball-joint through the spherical hinge of the indent of its end, and recessed ball-joint has the degrees of freedom around the pin swing.
Beneficial effect: the present invention compared with prior art has simple in structurely, and less, the lower-cost advantage of volume can adapt to needs small-sized or the micromechanics transmission.
