Description
Technical field
The utility model relates to mechanical keyless device, especially a kind of easily installing/dismounting hydraulic locking dish.
Background technique
Usual hydraulic locking dish is made up of outer shroud, inner ring, set screw nut, locking nut and four seal rings.Outer shroud endoporus makes two step conical surfaces and a straight step surface; The outer fenestra of inner ring makes two step conical surfaces and small end outside thread; Set screw nut endoporus and cylindrical all make screw thread; Locking nut endoporus makes internal thread.Two conical surfaces of inner ring match with two conical surfaces of outer shroud, and all scribble lubricating grease between the conical surface.The internal thread of set screw nut is connected with the outside thread of inner ring, and its outside thread connects with the internal thread of locking nut.Seal ring together with the endoporus of set screw nut and cylindrical and inner ring respectively have with the surface of contact place of outer shroud, seal ring together with two step conical surfaces of inner ring also respectively have with two step conical surface places of outer shroud.
Just in inner ring, form main seal cavity between outer shroud and set screw nut after such connection, define auxiliary seal cavity at the step place of inner ring and outer shroud.The cylndrical surface of outer shroud arranges two oil throughs, leads to major and minor two Seal cages respectively.Hydraulic locking dish is installed to the transmission connection piece be locked---and on axle and axle sleeve, inner ring forms wedging relation between axle sleeve and outer shroud, by injecting high pressure oil to main seal cavity, promoting outer shroud and moving.When two step taper-face contact that outer shroud moves to design attitude and inside and outside ring can not move, rotation lock nut makes its end face and outer shroud end contact, now stop note high pressure oil and can high pressure oil be released, so just achieve locking, due to the wedging relation of the conical surface, a radial positive pressure is produced between the inner headed face of axle sleeve and the such friction pair of the external cylindrical surface of axle, when axle sleeve rotates, stiction will be produced between axle sleeve and axle, when driving torque is less than or equal to the moment of torsion that stiction can provide, namely achieve effective moment of torsion transmission.
Under normal circumstances, owing to having lubricating grease between inner ring and the conical surface of outer shroud, and the cone angle of design is greater than theoretical Self-locking angle, when hydraulic locking dish needs dismounting, locking nut need be rotated backward, first locking nut is exited, outer shroud will move and unload by automatic reverse, and now because hydraulic pressure has unloaded, the end face of locking nut and the end face of outer shroud are tightly affixed, cause and rotate backward locking nut difficulty, hydraulic locking dish is not torn open not get off, and high pressure oil must be injected to Seal cage, outer shroud forward moves, the end face of locking nut and the end face of outer shroud are departed from, rotate backward locking nut get back to locking before position, again high pressure oil is released, position before outer shroud then automatically returns to locking---the effort that operates is time-consuming.
In view of the foregoing, a kind of easily installing/dismounting hydraulic locking dish is now developed.
Model utility content
The purpose of this utility model is to overcome deficiency of the prior art, and provide a kind of easily installing/dismounting hydraulic locking dish, can realize fast easily mounting and dismounting hydraulic locking dish, structure is simple, easy to operate, saves time.
The utility model to achieve these goals, adopt following technological scheme: a kind of easily installing/dismounting hydraulic locking dish, by inner ring, middle ring, high-pressure oil passage, draw-in groove, outer shroud, first step, second step, silk hole placed by Seal cage, seal ring, key plate, bolt, fixed hole is formed; In axle sleeve, axle is set, sleeve outer circle face is corresponding with the inner headed face of inner ring to be arranged, side, inner ring periphery arranges middle ring, opposite side arranges outer shroud, form Seal cage between inner ring, middle ring, outer shroud, middle ring is arranged at least two high-pressure oil passages, the periphery of middle ring arranges draw-in groove, arrange key plate in draw-in groove, key plate is bolted on outer shroud.
Described outer shroud endoporus side arranges inner conical surface, opposite side ecto-entad sets gradually first step and second step, and during locking, first step aligns with the side of described draw-in groove, make key plate be arranged in draw-in groove by first step, between second step and middle ring, inner ring, form Seal cage.
The second step described in the correspondence of periphery side of described middle ring arranges seal ring, and middle ring endoporus side arranges internal thread, opposite side setting table terrace.
Side, described inner ring periphery ecto-entad sets gradually the long conical surface and cylndrical surface, forms step between the long conical surface and cylndrical surface, and the inner conical surface of the corresponding outer shroud in long conical surface side arranges seal ring, and the step surface described in the correspondence of side, cylndrical surface arranges seal ring; Inner ring periphery opposite side arranges outside thread, and described outside thread is corresponding with the internal thread of middle ring to be spirally connected.
Described key plate is at least two pieces, and key plate is set to arc, and key plate is arranged at least two bolts and place silk hole and at least two fixed holes, bolt makes key plate be fixed on the first step of outer shroud by fixed hole.
The beneficial effects of the utility model are:
There is one seal ring the long conical surface side of inner ring, owing to having lubricating grease between the long conical surface of inner ring and the inner conical surface of outer shroud, under immense pressure effect, lubricating grease can be extruded and enter Seal cage, contaminated liquid force feed, seal ring effectively by grease sealing between the inner conical surface and the long conical surface of inner ring of outer shroud, both ensured and improve lubrication effect and additionally reduced pollution to hydraulic oil.
The utility model is fixed the locked position of outer shroud by draw-in groove by key plate, instead of the locking nut on former hydraulic locking dish, not only reduces product cost and difficulty of processing, also can realize fast easily mounting and dismounting hydraulic locking dish.Such as when locking, inject high pressure oil to Seal cage, outer shroud forward moves, and the first step of outer shroud aligns with the side of described draw-in groove, is arranged in draw-in groove by key plate by first step, and key plate is bolted in outer shroud, after locking, can release high pressure oil; During dismounting, continue to inject high pressure oil to Seal cage, outer shroud forward moves, take out after the key plate dismounting in draw-in groove, then release high pressure oil, outer shroud oppositely movement returns to the position before locking, such locking plate is all unloadings just, and locking plate just takes off from axle sleeve easily.
The utility model structure is simple, easy to operate, can realize quick mounting and dismounting, save time, be applicable to promoting the use of.
