Description
Technical field
The present invention relates to a kind of diaphragm groups of shaft coupling, specifically, being that one kind being suitable for wind-driven generator shaft coupling
The MULTILAYER COMPOSITE diaphragm group and its preparation preparation method of device.
Background technology
High-speed shaft of wind generating set Special flexible shaft coupling be applied to land, offshore high-altitude cabin in (from the ground or sea about
At 75m), for coupling wind power gear case high speed axis and generator shaft, to transmit movement and torque, compensation is used to prepare mistake
The variation etc. of deformation and temperature after difference, installation error, carrying causes axial direction, radially and angularly deviates so that shaft coupling institute
The two axial lines of connection generate different degrees of relative displacement, if relative displacement is serious, will input shaft, output shaft, bearing with
And cause additional load on shaft coupling, or even there is high vibration.And the vibration of shaft coupling can become the main vibration source of entire wind turbine,
Once vibration is excessive, it is possible that intermediate tubular shaft is broken the accident to fly out.
Currently used diaphragm coupling is mainly by diaphragm group, ring flange, two end axles, intermediate tubular shaft and connection bolt group
At, wherein diaphragm group is combined mostly by one group or several groups of elastic stainless steel pieces to transmit torque, the phase between input and output shaft
Displacement is absorbed by diaphragm material.The existing common structure of diaphragm group is circular ring type, polygon formula and beam equipped with connecting hole
Waist formula.Due under the action of torque and centrifugal force, the connecting hole medium position of diaphragm there are stress concentration phenomenon, and pulling force and
The main reason for alternate stress caused by angular displacement is diaphragm fatigue loss, from the analysis of power it is found that having axial direction and angular displacement
Caused maximum stress all in the edge that diaphragm is contacted with gasket, that is, both ends connecting hole be easier to occur tension failure and
Diaphragm buckle in compression flexural deformation.To find out its cause, individually sub- diaphragm can not effectively be disperseed stress, compensated pursuing
The bearing capacity of diaphragm is ignored while ability or diaphragm ignores the compensation energy of diaphragm while pursuing bearing capacity
Power, existing sub- diaphragm are difficult to take into account its compensation ability and bearing capacity due to the limitation of structure and material.
In terms of material, the diaphragm used at this stage is broadly divided into：1, cold-rolling stainless steel piece or aluminium film piece, build up one group
Or it is multigroup, it is connected between driving shaft and driven shaft by connecting bolt, although intensity is high, toughness is not good enough, and metal
Diaphragm is influenced by environment temperature, humidity and cavitation, is slowly changed in the operating condition, and performance declines, in alternating download
Lotus effect is lower to occur fatigue fracture；2, rubber material, as with diaphragm made of nitrile rubber have preferable corrosion resistance and
Weatherability, but diaphragm made of existing nitrile rubber easily under big, the of reciprocating vibration environment of pressure change aging, fatigue and
Fracture, and be difficult to diaphragm made of pure rubber material to meet heatproof, pressure resistance and fatigue proof composite request.

The distribution of matter, and improve the physical property and working properties of alloy.In the preparation process of the sub- diaphragm of the titanium alloy 11, Sc and
Al can form multiple compounds such as ScAl3、ScAl2, ScAl adding to easily forming oversaturated solid solution in crystallization process
The ScAl of coherence is easily precipitated in heat and extrusion process3Particle so as to strong inhibition recrystallization process and improves the titanium alloy
The stability of sub- diaphragm 11.
Wherein, since Co elements can improve the resistance to crack corrosivity of Ti alloys, and Co and Sc mating reactions, it is able into one
Step enhances the corrosion resistance of the titanium alloy diaphragm group 10, and Co and Sc cooperate with work in the sub- diaphragm of the titanium alloy 11 in order to obtain
With the amount of Co is 0.03% or more.But if the excessively high corrosion resistance that can make Ti alloys instead of the content of Co reduces, preferably
Ground, the containing ratio of Co is between 0.03~0.16%.
To, since the intensity and fatigue resistance of the sub- diaphragm of the titanium alloy 11 are largely increased, thickness phase
To relatively thin.

So that transconfiguration in TPI retains, the performance for keeping TPI excellent, such as high rigidity, heat is low, wear-resisting property and dynamic are tired
The characteristics of labor function admirable.Simultaneously as TPI is crystalline high polymer, and strand ordered arrangement in crystalline region, activity drop
It is low, there is higher heatproof air aging performance, the ETPI synthesized after epoxidation still to have the TPI of part to crystallize, these crystallites
It is distributed in PTT, TPEE and plays the role of physical crosslinking, increase the crosslink density of sizing material, contribute to the compounded rubber film
The synthesis of piece 20.
Wherein, PTT is able to form by terephthalic acid (TPA) (PTA) and 1,3-PD (PDO) polycondensation.Main chain is by each
Repetitive unit is the saturated linear molecular composition that rigid phenyl ring and flexible fatty alcohol connect, the height geometrical regularity of molecule
Make whole system that there is high mechanical strength, chemical reagent resistance outstanding and heat resistance, and PTT structures pair with rigid element
Claim, meets the requirement closely piled up, be suitable as the framework material of the compounded rubber diaphragm 20, meet its intensity requirement.
Wherein, TPEE is the block copolymer containing polyester hard section and polyester soft segment, wherein polyester soft segment and uncrystallized
Polyester forms amorphous phase polyester hard section, and partially crystallizable forms crystalline domains, plays physical crosslinking point.TPEE has rubber
Elasticity and engineering plastics intensity；Soft segment assigns its elasticity, makes it have rubber performance；Hard section assigns its processing performance, makes
It has plastics performance；With rubber phase ratio, TPEE has better processing performance and longer service life；Compared with engineering material,
Equally have the characteristics that intensity is high, and flexibility and dynamic mechanical are more preferable.The addition of TPEE is able to be obviously improved macromolecular
Segment freely changes the ability of microcosmic conformation, and TPEE can form the interspersed structure of interpenetrating networks with ETPI, PTT, be effectively improved institute
State mechanical property such as hardness, stretching yield stress and the yield elongation rate of compounded rubber diaphragm 20.
Wherein, the unsaturation (- C=C-) of vinyl silanes can graft on TPEE, ETPI, improve the compatible of whole system
Property.
