The coupling has simple structure, convenient maintaining and replacement, and is widely applied to transfer the torque in mechanical shaft systems of various industries.

Description

A kind of quick removable Hooks coupling universal coupling

Technical field

The utility model relates to a kind of coupling, particularly a kind of quick removable Hooks coupling universal coupling.

Background technique

Transmitting torque is often used coupling in the mechanical axis system of metallurgy, lifting, engineering transportation, mine, oil, boats and ships, coal, rubber, papermaking equipment and other heavy industry industry, coupling is of a great variety, according to the relative position of coupled diaxon and the change conditions of position, can be divided into: permanent coupling, self-alignment formula coupling and Hooks coupling universal coupling.Hooks coupling universal coupling is mainly used in diaxon to be had big angle of declination or place than Angular Displacement is arranged at work, common Hooks coupling universal coupling has Rzeppa type Hooks coupling universal coupling, universal coupling with spider or the like, and these Hooks coupling universal coupling mechanism complexity, couple together time-consuming, inconvenient maintain and replace.

The model utility content

Technical problem to be solved in the utility model is to provide a kind of removable fast Hooks coupling universal coupling simple in structure, easy to connect.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of quick removable Hooks coupling universal coupling, form by two connecting heads and a spherical connecting head, the first end of described connection is a connecting sleeve, the other end is a coupling hook, the prong of described coupling hook is a circular arc, the circular arc degree of described prong is greater than 180 degree, and the circular arc prong of connecting head bottom is provided with the breach that the coupling hook for another connecting head passes therein; Described spherical joint is the entity ball that is provided with the jaw slideway of two orthogonal rings, the little entity ball of the center of described two jaw slideways is cut two spherical crowns at two jaw slideway infalls by two parallel plane symmetries of vertical jaw slideway, and described two plane-parallel distances are less than the A/F of the prong of coupling hook.

As improvement of the technical scheme, the circular arc prong of two connecting heads bottom is equipped with the breach that the coupling hook for another connecting head passes.

As another improvement of technique scheme, described coupling hook and connecting sleeve connecting part are circular arc.

The beneficial effects of the utility model are: quick separable coupling of the present utility model only is made up of two connecting heads and a spherical joint, and structure is very simple, does not need bolt or pivot pin during connection, and convenient for maintaining is changed.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, a kind of quick removable Hooks coupling universal coupling is made up of two connecting heads 1 and a spherical connecting head 2, connecting head 1 one ends are connecting sleeve 3, the other end is a coupling hook 4, the joint of connecting sleeve 3 and coupling hook 4 can be made circular-arc, can increase the intensity of connecting head like this.The prong of coupling hook 4 is a circular arc, and the circular arc degree of described prong is preferably got 240 degree greater than 180 degree.The circular arc prong of a connecting head 1 bottom leaving certain gaps uncovered by the economic plan 5 therein, breach 5 are used for passing when connecting for another connecting head.Spherical joint 2 is the entity ball that is provided with the jaw slideway 6 of two orthogonal rings, article two, the center of jaw slideway 6 forms a little entity ball 7, little entity ball 7 is cut the spherical crown part at two jaw slideway infalls by two parallel plane symmetries of vertical jaw slideway, and described two plane-parallel distances are less than the A/F of the prong of coupling hook.

Quick removable Hooks coupling universal coupling assembling sequence of the present utility model is: the connecting head with prong bottom band breach 5 inserts in the spherical joint along two planes of little entity ball 7 earlier, spherical joint revolved turn 90 degrees, another connecting head is also inserted in the spherical joints along two planes of little entity ball 7, revolve then to turn 90 degrees and get final product.

Convenient for easy to assembly and production and processing, the breach that the coupling hook for another connecting head passes is all left in the circular arc prong bottom of two connecting heads.

Quick removable Hooks coupling universal coupling of the present utility model utilizes a spherical joint that two connecting heads are coupled together dexterously, do not need bolt or pivot pin, have the advantages that simple in structure, convenient for maintaining is changed, can be widely used in transmitting torque in the mechanical axis system of industry-by-industry.
