Description
Technical field
This utility model relates to coupler structure technical field, is specially a kind of hydrocoupling.
Background technology
Shaft coupling is to connect two axles or connect parts of axle and revolving meber, together turns round at transmitting movement and dynamic process natural axis and does not disengage.Having a kind of hydrocoupling in shaft coupling, the inner sleeve of it overcoat including coaxial sleeve heavy wall together and thin-walled, wherein, the inner peripheral surface of overcoat and the outer peripheral face of inner sleeve are with certain tapering corresponding matching.This kind of hydrocoupling when mounted, is radially injected hydraulic oil and makes its conical surface chien shih inner sleeve be pressed on axle, and overcoat is expanded；Axial oil injects plunger shaft makes overcoat engage the conical surface to the big Slideslip of inner sleeve diameter along inner sleeve, inner sleeve is forced to be shunk, overcoat is expanded, when the moving displacement of overcoat reaches design flow, unscrew bolt and bleed off hydraulic oil, now, there is normal pressure between inner sleeve and overcoat interference fit face, the frictional force that during work, normal pressure produces whereby transmits moment of torsion.When applying axial oil pressure; in order to prevent plunger shaft leakage of oil; the rubber seal of one planar shaped would generally be installed inside piston; but owing to rubber seal material is softer; course of exerting pressure by rubber seal crimp, can be able to be squeezed under serious conditions in the screw thread that piston and inner sleeve match, thus causing after when repairing; piston is non-dismountable with inner sleeve thread biting locking, directly contributes scrapping of shaft coupling.
Utility model content
For the problems referred to above, this utility model provides a kind of hydrocoupling, its can solve existing hydrocoupling when applying axial oil pressure the easy compressive deformation of rubber seal and be squeezed into the problem that causes piston and inner sleeve thread biting locking in the screw thread that piston and inner sleeve match.
nullIts technical scheme is such，It includes inner sleeve and overcoat，The coaxial sleeve of described inner sleeve is in described overcoat and the inner peripheral surface of described overcoat is tapered with the outer circumference surface of inner sleeve coordinates，The endoporus of described inner sleeve is isometrical circular hole，First axle、Second axle inserts from two ends in the endoporus of described inner sleeve respectively，One end less at described overcoat diameter of bore is provided with step piston chamber，The axially external end in described step piston chamber is provided with piston and described piston thread is connected on the straight platform in front end of described inner sleeve，Described step piston chamber is by described piston seal，The body of described overcoat has the first hydraulic fluid port connected with described step piston chamber，The stage casing of described outer sheath inner circumferential surface is provided with the oil groove of screw thread shape，The body of described overcoat also has through body and the second hydraulic fluid port connected with described oil groove，It is characterized in that: the periphery of described piston、The annular ditch groove having on inner headed face，In described annular ditch groove, O-ring seals is installed，The outside of described piston is provided with piston unt，Described piston unt is threadedly connected to the outboard end of described inner sleeve.
Further, the cross section of described annular ditch groove is square-section.
Further, the periphery of described piston, inner headed face has the annular ditch groove of two parallel described square-sections respectively.
Further, the axially external end of described piston unt is provided with pressure ring, is fastened by trip bolt between the end face outside of described pressure ring and described overcoat.
Further, described overcoat is provided with adpting flange away from one end of described piston, the central axes of the central axis of described adpting flange and described overcoat.
Further, described overcoat and described adpting flange are wholely set.
The beneficial effects of the utility model are in that: it is by the annular ditch groove opened respectively on the periphery of piston, inner headed face and installs O-ring seals in ring-shaped groove, the leakage of oil of step piston chamber is effectively prevented, thus overcoming the easy compressive deformation of rubber seal of existing traditional planar shaped and being squeezed in the thread pitch of piston and inner sleeve, cause piston and inner sleeve thread biting locking to dismantle and the problem scrapped by O-ring seals.
