Abstract
The utility model belongs to the technical field of a shaft coupling, and specifically relates to the improvement of a traditional universal joint. The utility model is composed of a telescopic outer sleeve, a flexible lapping sheet and a hinged shaft, wherein, the section area of the telescopic outer sleeve is a square, and a spacer pin is transversely penetrated in the sleeve; the left end of the flexible lapping sheet is provided with a slotted hole which is connected with the telescopic outer sleeve through the spacer pin, and the flexible lapping sheet is connected with the hinged shaft at a right side. The flexible lapping sheet is punched and shaped by a rust-proof steel sheet with high elasticity, the steel sheet is provided with a self lubricating coat, the steel sheet with high elasticity is bent into a U shape, and a non-metal elastic sandwich layer made of composite material, such as spun glass or carbon fiber, is clamped in a U-shaped lapping sheet. The utility model has the advantages of small external dimensions, large transferring torque, buffering capacity, the relief of lubricating steps and long service life. The utility model can be served as the connection of transmission shafts of automobiles and motorcycles, the connection of screw propellers of aeroplanes, and the connection of rotary wings and engines or propeller bosses of helicopters, and the utility model is more suitable for a driving shaft of a non steering wheel of a military off-road vehicle.
Description
Technical field:
The utility model belongs to the coupling technical field, is specifically related to the improvement to traditional universal joint.
Background technique:
The present bigger universal joint of usage quantity in automobile, motorcycle and aircraft transmission and operation system, wherein great majority are universal joint crosss, its boundary dimension is big, transmitting torque is little, working life is short, and general universal joint cross is no buffer capacity, very easily is damaged when being subjected to rough impulsive load, in case when being damaged, will cause serious consequence.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of boundary dimension little, and transmitting torque is big, has outstanding buffer capacity and than the flexible buffering universal joint of the composite material laminated type of long life.
The technical solution of the utility model is: this universal joint is formed by connecting by left, center, right three parts, the left side is that sectional area is foursquare flexible outer sleeve, cross a position limit pin in the sleeve, intermediate portion is flexible laminate patch, the left end of flexible laminate patch has a slotted hole, connect with flexible outer sleeve by position limit pin, flexible laminate patch is connected by rotating shaft with the hinging shaft on right side; Described flexible laminate patch is by the impact briquetting of rust-proofing high elasticity steel disc, steel disc has self-lubricating coat in use, the high elasticity steel disc curves " U " shape, nonmetal elastic interlayer, its thickness and the left half sleeve position limit pin equal diameters of the composite material that one on folder is made by glass fibre or carbon fiber in " U " shape laminate patch mouth.
Good effect of the present utility model is that boundary dimension is little, transmitting torque is big, has buffer capacity, remove lubricated step from, long working life, can be used as transmission shaft, wind stick, helicopter rotor and the motor of automobile, motorcycle or being connected of propeller hub, be suitable for the live axle of the non-steered wheel of military go-anywhere vehicle especially.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the section of structure of the flexible outer sleeve of the utility model;
Fig. 3 is the structural profile schematic representation of the flexible laminate patch of the utility model.
Embodiment:
Referring to Fig. 1, the utility model is formed by connecting by left, center, right three parts, the left side is that sectional area is foursquare flexible outer sleeve 1, cross a position limit pin 2 in the sleeve 1, intermediate portion is flexible laminate patch 3, the left end of flexible laminate patch 3 has a slotted hole, connects with flexible outer sleeve 1 by position limit pin 2, and flexible laminate patch 3 is connected by rotating shaft 4 with the hinging shaft 5 on right side; Described flexible laminate patch 3 is by the impact briquetting of rust-proofing high elasticity steel disc, steel disc 8 has self-lubricating coat in use, the high elasticity steel disc curves " U " shape, the nonmetal elastic fixture block 7 of the composite material that one on folder is made by glass fibre or carbon fiber in " U " shape laminate patch mouth, its thickness and left half sleeve position limit pin 2 equal diameters, form composite material moment of torsion transfer body by double layer of metal laminate patch 8 and nonmetal fixture block 7, it has the bending angle of 18-20 degree, produces buffer function because of its shape is bent simultaneously in the transmitting torque process.Right side hinging shaft 5 is connected with oilite bushing 6 by rotating shaft 4 with flexible laminate patch 3, can 4 do 20 degree rotations around the shaft.Flexible laminate patch 3 has enough slippages in flexible outer sleeve 1, but can not pull out from flexible outer sleeve 1, thinks that it has the position limit pin restriction, and the slip of flexible laminate patch 3 in flexible outer sleeve 1 is in order to eliminate the huge axial tension that produces in the twisting process.
Flexible as can be seen from Figure 3 laminate patch 3 is formed metal laminate patch 8 thick 0.18-0.2 millimeters by metal laminate patch 8 and nonmetal 7; Right side hinging shaft 5 links to each other with the opposite side of " U " shape laminate patch 3 by oilite bushing 6 and rotating shaft 4, and rotate in 4 axle center around the shaft, and rotational angle is greater than 20 degree, and the utility model just can freely rotate in 20 degree conical solid angle like this.Because the buffering that produces because of deformation that flexible laminate patch 3 self has.
