Description
Technical field
Land power apparatuss such as the utility model relates to military, peculiar to vessel and airport, telecommunication, factory, hospital, residential quarter, building site: the coupling design of diesel generating set.
Background technique
Coupling is in diesel generating set, though the cost share that accounts for is very little, its structure but is one of key factor that influences the diesel generating set ride quality.Therefore, the design of coupling is one of hot issue of diesel generating set industry always.Diesel generating set is when assembling, and owing to reasons such as machining errors, always there is certain error that misaligns in the revolution shaft axis of crankshaft of diesel engine and machine shaft, and this error comprises the parallel shift sum of errors angular displacement error of diaxon shaft axis.Rigid coupling can not compensate above-mentioned error.Facts have proved that even at motor fuselage footing face vibration damping (rubber) pad has been installed, this error still can cause particularly motor component distortion of unit, vibration, make motor component fatigue damage etc. prematurely.Though the flexible coupling of band rubber element can compensate this error, because rubber element is usually to surpass 110 ℃ inner use of unit in temperature, so rubber element is easily aging, fatiguability damages.
Summary of the invention
The purpose of this utility model is to provide a kind of novel metal flexible laminated membrane coupling, this novel metal flexible laminated membrane coupling has overcome in the past metallic laminations and has got the lamination mounting hole of axial organ and the processing that the screw external diameter causes because of matching gap is very little, the difficulty of installation, and the lamination mounting hole of this metallic laminations coupling is the cooperation of adopting big gap with cooperating of screw external diameter.
The technical solution of the utility model is: a kind of novel metal flexible laminated membrane coupling, this coupling comprises the diesel engine flywheel, diesel engine flywheel endoporus is provided with lamination, lamination is by two groups of circular holes on the lamination, uses screw in compression on diesel engine flywheel and motor half-coupling, and each circular hole is the cooperation with monolateral 0.5-1.5mm gap with cooperating of screw cylindrical.The thickness of individual lamination is that 1-2mm is thick.
Advantage of the present utility model is: this novel metal flexible laminated membrane coupling is compared with the conventional metals flexible laminated membrane coupling, and processing and assembly process process are good, and cost is low.Its carry-over moment is fully by the frictional force between the disc.

Embodiment
A kind of novel metal flexible laminated membrane coupling, lamination 2 circular discs commonly used, material are heat-resistance stainless steel 1Cr18Ni9Ti, single face gap between the mounting hole of coupling lamination 2 and screw 3 external diameters is big, single face gap h is between 0.5mm and 1.5mm, screw 3 does not play the pin positioning action, also do not have other pin on the coupling, and the thickness t of individual lamination 2 is between 1mm and 2mm.
After the screw mounting hole of the lamination 2 of the utility model metallic laminations coupling strengthened, its stressing conditions changed to some extent.Radially, it is subjected to the pressure of motor rotor core and the support force of diesel engine flywheel 1 inner hole surface; Axially, be subjected to the pressure of screw 3 and the support force of motor half-coupling 4 and flywheel 1 end face; Circumferentially, be subjected to the frictional force of the frictional force of screw 3 and motor half-coupling 4, flywheel 1 end face.Be subjected to the distortion of the lamination 2 of three-dimensional force effect, the method for utilization classical mechanics is difficult to obtain.If the distortion of lamination 2 is too big, promptly too " softened ", the metallic laminations coupling does not then reach the transmission accuracy requirement, motor stator and rotor iron core is collided promptly sweep boring, causes serious accident; The distortion of lamination 2 is too little, and promptly too " just ", the metallic laminations coupling become rigid coupling again, do not have the effect that compensation crankshaft of diesel engine and rotor axis of electric misalign error.The utility model metallic laminations coupling, the moment of torsion that it transmits is not difficult to obtain with the classical mechanics method, and designing main difficult point is to ask the distortion of its metallic laminations.
The laminate of metallic laminations coupling is selected 1mm or the thick 1Cr18Ni9Ti corrosion resistant plate of 2mm for use.Lamination 2-circular disc, excircle dimension is an industry standard, inconvenience changes.Therefore the distortion of lamination 2 is a rigidity, then depends on the quantity of lamination 2.
The utility model asks the quantitative approach of lamination 2 as follows:
(1) obtains the stressed sketch of rotor.Shown in Figure 2 is a kind of stressed sketch (not marking data) of rotor of diesel generating set of model.
(2) obtain the relevant stressed sketch of a lamination.Shown in Figure 3 is the stressed sketch (not marking stressed data) of a kind of lamination of the utility model metallic laminations coupling.
(3) obtain the distortion of lamination with the Ansys finite element software, determine the quantity of lamination.
Utilize the Ansys finite element software that lamination is carried out pretreatment (as shown in Figure 4), finds the solution and reprocessing.Can obtain the displacement cloud atlas and the stress cloud atlas of lamination 2 nodes.Can inquire the maximum internal stress and the maximum distortion (shown in Fig. 5,6) of lamination 2.And whether the maximum distortion that can judge lamination 2 is resiliently deformable.After judging that lamination 2 distortion are resiliently deformable, according to 2 stacks of several laminations, it is subjected to stress, strain capacity also to be the rule that linear elasticity changes, determine the sheet number of lamination 2, thereby the comprehensive deformation that guarantees lamination 2 but is unlikely to too little in the scope that motor allows, preferably approaching.
