Description

Flexible connection element
Technical field
The present invention relates to a kind of mechanical axis is the coupling that uses in the transmission.
Background technique
Power transmission system usually for some reason or other, makes each component in the transmission system produce bigger displacement in running, causes bigger additional stress, when serious even the destruction that can cause component.
Be the displacement of compensating shaft system, the normal metal flexible connection element that adopts various types in axle system, linkage member commonly used has diaphragm type coupling, flexibility bar coupling, diaphragm coupling or the like.Because the restriction of material self-characteristic and structure, the bit shift compensation effect of previously used flexible connection element is limited, particularly by impacting under the big displacement situation that produces, depends merely on the big bit shift compensation purpose of the very difficult realization of distortion of metallic material.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of flexible connection element, and it is simple in structure, possess better big bit shift compensation performance.
For solving the problems of the technologies described above, flexible connection element of the present invention comprises a tie-plate, a flange minor axis, a plurality of rubber arthrosis assembly, described flange minor axis is arranged on the distolateral of tie-plate, described a plurality of rubber arthrosis assembly is evenly distributed on the end face of tie-plate, and the one end is fixedlyed connected with tie-plate, and the other end is fixedlyed connected with the flange minor axis.
Because adopt said structure, flexible connection element of the present invention has constituted a kind of rubber arthrosis coupling.It possesses extraordinary respectively to compensation ability, by the rubber arthrosis assembly possess radially, axial stretching and each be to the combined deformation ability of reversing, especially use two cover rubber arthrosis coupling of symmetric configuration can provide stronger axially, radially with the angular displacement compensation performance, guarantee the work that power system is safe and reliable.The shock resistance compensation rate is required (comprise axially, angle, radially) very big application, and the rubber arthrosis coupling also can meet the demands.
Rubber arthrosis coupler structure compactness of the present invention possesses the advantage that optimization system is arranged.Intermediate support assembly can be reduced to shorten and to simplify rotating speed, the arrangement requirement that drive line satisfies system by adopting the rubber arthrosis coupling in the application of have relatively high expectations at some rotating speed, the arrangement space strictness limiting.
Rubber arthrosis coupler structure of the present invention is simple, dismounting is simple and easy, be easy to maintenance.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and embodiment:
Fig. 1 is rubber arthrosis coupling example structure figure of the present invention;
Fig. 2 is the rubber arthrosis assembly assumption diagram among Fig. 1;
Fig. 3 is a subelement structural drawing in the rubber arthrosis assembly shown in Figure 2;
Fig. 4 is that rubber arthrosis coupling of the present invention is used schematic representation.
Embodiment
Referring to Fig. 1, in a specific embodiment of the present invention, described flexible connection element is made up of tie-plate 1, rubber arthrosis assembly 2, flange minor axis 3, bolt I4 and bolt II5.Described flange minor axis 3 is arranged on the distolateral of tie-plate 1, a plurality of rubber arthrosis assemblies 2 are evenly distributed on the end face of tie-plate 1, and the one end is fixedlyed connected with tie-plate by bolt I4, and the other end is fixedlyed connected with the flange minor axis by bolt II5, has constituted a kind of rubber arthrosis coupling.
The structure of described rubber arthrosis assembly 2, as shown in Figure 2.It comprises guide I21, spherical rubber joint 22, stopper ring 23, connecting rod 24, gland 25, packing ring 26, cylindrical rubber joint 27, guide II28.Wherein, spherical rubber joint 22 (referring to Fig. 3 a), cylindrical rubber joint 27 (referring to Fig. 3 b), packing ring 26 (referring to Fig. 3 c) be for the metalwork and the vulcanization of rubber form, all the other elements are metalwork.
Connecting rod 24 two ends respectively have a hole, and two axially bored lines are orthogonal.Spherical rubber joint 22 is that interference fit connects with guide I21, be installed in then in the hole of an end of connecting rod 24, and the end face in spherical rubber joint 22 is provided with stopper ring 23.Spherical rubber joint 22 connects with the hole interference fit of connecting rod 24.Cylindrical rubber joint 27 is that interference fit connects with guide II28, is installed in then in the hole of the other end of connecting rod 24, and gland 25 is arranged on the end of guide II28 by packing ring 26.Cylindrical rubber joint 27 connects with the hole interference fit of connecting rod 24.
As shown in Figure 1, when described rubber arthrosis coupling was worked, power was by tie-plate 1 input, and moment of torsion is passed to the 3 back outputs of flange minor axis by rubber arthrosis assembly 2.By means of 2 liang of stomidium endospheres of rubber arthrosis assembly shape rubber arthrosis 22 and cylindrical rubber joint 27 radially, axial stretching and each be to the combined deformation ability of reversing, the rubber arthrosis coupling can realize that better each is to compensation performance.
As shown in Figure 4, power is passed to gear-box input flange 36 by 31 inputs of diesel engine flywheel end through highly elastic shaft coupling 32, rubber arthrosis coupling I33, carbon fiber axle 34, rubber arthrosis coupling II35.Because two cover rubber arthrosis coupling 33,35 that the employing symmetry is installed and light weight, the carbon fiber axle that intensity is high, this drive line possesses big respectively to displacement compensation capability, satisfy each requirement of shock resistance to compensation, simultaneously can save parts such as intermediate support, bearing, effectively simplify axle system of system and arranged.
Rubber arthrosis shaft coupling of the present invention is the resilient connection that is formed by rubber and metallic combination Element, as a kind of novel driving coupling element, rubber arthrosis not only have flexibly connect, big position Move the effect of compensation, the effect that buffering vibration impacts, also have need not to lubricate, non-maintaining, low noise, Advantages of simple structure and simple. Can predict, the rubber arthrosis shaft coupling will be at machinery, automobile, boats and ships etc. The field obtains using more and more widely.
