Description
Technical field
The utility model relates to a kind of mechanical transmission, particularly the contactless free wheel device of a kind of hydraulic pressure.
Background technique
In recent years, that realizes energy-conserving and environment-protective along with the extensive use of turbine engine and people improves constantly, more and more urgent to the demand of high speed operation free wheel device on market, free wheel device one termination drive end, another termination driven end, lubricant oil is pressed into voussoir braking interval region by the oil pump meeting hydraulic principle by inner of installing during work.The clutch that can meet this operating mode in the market has two kinds of forms, and one is 3S clutch, and the design of this clutch configuration is accurate, and installation precision requires high, price and the manufacture cycle longer, application is very restricted.Another kind is box-type overrunning clutch, and this clutch is owing to limitting by structure, and inside is solid matter voussoir, and in using process, wearing and tearing are very fast, and volume is comparatively large, and impact is promoted.The free wheel device of above structure all cannot meet the market demand of requirements at the higher level.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hydraulic pressure contactless free wheel device, has reasonable in design, and manufacturing process is simple, and functional reliability is strong, and bearing torque is large, surmounts, in conjunction with the high feature of rotating speed.
To achieve these goals, the technical solution adopted in the utility model is:
The contactless free wheel device of a kind of hydraulic pressure, comprise outer shroud 1 and inner ring 2, outer shroud 1 is connected with output shaft 8 by screw 11, inner ring 2 is connected with input shaft 9 by key 10, voussoir A1 is constrained on outer shroud 1 endoporus working surface by support spring A2, realize movement in one direction, baffle plate 4 is arranged on outer shroud 1 end face by cross recessed countersunk head sscrew C5 and plays position-limiting action, deep groove ball bearing C2 and voussoir A1 isolates by outer back-up ring 3, deep groove ball bearing C2 plays certralizing ability, rotary shaft lip seal C1 connects deep groove ball bearing C2, deep groove ball bearing C2 connects inner ring 2 one end outer wall, oil cylinder 5 connected pipes 6, oil pipe 6 connects oil pump 7, form a set of lubricating fitting meeting hydraulic principle, fluting flat point set screw C6 is used to fix its position, be fixed in inner ring 2 the other end outer wall, hexagon socket cap head screw C3 is for connecting outer shroud 1 and oil cylinder 5, O type rubber seal C4 is used for sealed cylinder 5 and outer shroud 1 conjunction plane,
The bottom of the contactless free wheel device of described hydraulic pressure is provided with Cross Recess Head Screw H type C7 for the sealing of tank filler sleeve and plain washer C8.
Described output shaft 8 is driving shaft.
Described input shaft 9 is driven shaft.
The beneficial effects of the utility model are: be applicable to the high speed of occasion that drives more and throw off and combination, by the contactless design of hydraulic pressure, thus the working life of clutch is significantly extended, built-in hydraulic oil pump avoids lubricant oil frequently and safeguards, significantly extends bearing and voussoir working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The contactless free wheel device of a kind of hydraulic pressure, comprise outer shroud 1 and inner ring 2, outer shroud 1 is connected with output shaft 8 by screw 11, inner ring 2 is connected with input shaft 9 by key 10, voussoir A1 is constrained on outer shroud 1 endoporus working surface by support spring A2, realize movement in one direction, baffle plate 4 is arranged on outer shroud 1 end face by cross recessed countersunk head sscrew C5 and plays position-limiting action, deep groove ball bearing C2 and voussoir A1 isolates by outer back-up ring 3, deep groove ball bearing C2 plays certralizing ability, rotary shaft lip seal C1 connects deep groove ball bearing C2, deep groove ball bearing C2 connects inner ring 2 one end outer wall, oil cylinder 5 connected pipes 6, oil pipe 6 connects oil pump 7, form a set of lubricating fitting meeting hydraulic principle, fluting flat point set screw C6 is used to fix its position, be fixed in inner ring 2 the other end outer wall, hexagon socket cap head screw C3 is for connecting outer shroud 1 and oil cylinder 5, O type rubber seal C4 is used for sealed cylinder 5 and outer shroud 1 conjunction plane,
The bottom of the contactless free wheel device of described hydraulic pressure is provided with Cross Recess Head Screw H type C7 for the sealing of tank filler sleeve and plain washer C8.
Described output shaft 8 is driving shaft.
Described input shaft 9 is driven shaft.
Working principle of the present utility model is:
During use, outer shroud 1 rotates, in grease chamber, form oil ring, and oil guide pipe is immersed in ring.Once outer shroud 1 rotating speed exceedes inner ring 2 rotating speed, under pressure, oil pressure enters in grease chamber by oil guide pipe, and then oil flows through from the gap high speed of ring and axially flows into the interval region of voussoir A1 braking; According to the relative rotation speed of inner ring 2 and outer shroud 1, oil stream flows into voussoir A1 with certain angle and brakes in interval region, produces a reaction force, is lifted, realizes non-contact by voussoir A1 from inner ring 2; When outer shroud 1 and inner ring 2 relative rotation speed reduce, lifting force also declines; Before reaching synchronous operation, voussoir A1 braking has been pressed close in inner ring 2 again, and overrunning clutch can realize locking, realizes non-contact by hydraulic system, makes clutch when surmounting at a high speed state almost without wearing and tearing.
