Description
Technical field:
The utility model relates to a kind of coupling, particularly a kind of serpentine spring split type coupling.
Background technique:
At present, coupling is divided into cog-wheel coupling and elastic coupling flexible coupling substantially on structure function, because cog-wheel coupling can be larger bearing load impact and live load, have more safety when making startup or load uneven, and the Flexible Transmission of elastic coupling flexible coupling by spring absorbs a large amount of vibration forces, so play a different role separately.
Each halfbody of the large-scale coupling of prior art is whole, have following shortcoming on connecting mode: interference fit, heating are installed, the one-time mechanical hydraulic performance decline is removed, often torn open to uneven heating after making pressure can exert an influence, heat product after uneven, heating thereupon by force, successively cumulative, easily cause the surface to pull.If certain component in drive portion and coupling itself are damaged, the mounting or dismounting of the coupling of whole halfbody are difficulty especially, needs very large pulling force, and must move just vertically and can install and remove.When especially using in the down-hole, the reason such as limited due to installing space, that crane capacity is not enough is given maintenance or changes the component that damage in drive portion and brought larger obstacle.
Summary of the invention:
In view of this, be necessary to provide a kind of easy accessibility and serpentine spring split type coupling simple in structure.
a kind of serpentine spring split type coupling, this serpentine spring split type coupling comprise serpentine spring, two coupling halfbodies, coupler casing, case connecting bolt, serpentine spring connects two coupling halfbodies, the coupling halfbody is comprised of the first semicircle coupling halfbody and the second semicircle coupling halfbody, after fastening, the first semicircle coupling halfbody and the second semicircle coupling halfbody form described coupling halfbody, offer axial keyway on the semicircle inner tubal wall of the first semicircle coupling halfbody, the first semicircle coupling halfbody, the corresponding screw that is provided with on one end of the semicircle outer tube wall of the second semicircle coupling halfbody, the first semicircle coupling halfbody and the second semicircle coupling halfbody pass through bolt, the screw Placement is relatively fixing.The other end of the semicircle outer tube wall of the first semicircle coupling halfbody, the second semicircle coupling halfbody is provided with the teeth groove that embeds for serpentine spring.
Preferably, an end of the semicircle outer tube wall of the first semicircle coupling halfbody, the second semicircle coupling halfbody is provided with screw, is provided with paper washer between the junction plane of two semicircle coupling halfbodies.
Preferably, correspondingly on an end of the semicircle outer tube wall of the first semicircle coupling halfbody, the second semicircle coupling halfbody be provided with two groups of screws, connect respectively the tube wall of the second semicircle coupling halfbody, the first semicircle coupling halfbody by bolt.
Preferably, two of the teeth groove of couplings outside lane flank of tooth are comprised of a plurality of arc shaped surfaces.
Preferably, the surface of serpentine spring is through accurate sand blast.
above-mentioned serpentine spring split type coupling has adopted the halved body of Bolt Connection coupling, that is first semicircle coupling halfbody and the second semicircle coupling halfbody form described coupling halfbody after fastening, tighten by high-strength bolt the powerful interference power that produces during use, transmit larger moment of torsion, certain component and coupling itself in drive portion are damaged, twist off the first semicircle coupling halfbody, bolt on the second semicircle coupling halfbody, need not just move vertically and can remove the halved body of coupling, so that maintenance or replacing damage component.Therefore above-mentioned serpentine spring split type coupling has easy accessibility and advantage simple in structure with respect to prior art.
