Abstract
The invention discloses a laminated coupler integrated with a fan highly. The laminated coupler is applied to a diesel generating set. By improving the designs of some parts of a diesel generator rotor assembly, the axial total length of a generator rotating shaft is reduced, a shaft sleeve for installing laminated pieces 9 of the coupler is omitted, and the laminated pieces 9 of the coupler are directly integrated on a fan shaft sleeve 2. Therefore, parts for machining the diesel generating set and assembling procedures are reduced, the production cost is lowered, the set manufacturing cycle is shortened, and the axial dimension and the total weight of the diesel generating set are also reduced.
Description
Technical field
The present invention relates to diesel generating set coupling field, particularly with the integrated flexible laminated membrane coupling of fan height.
Background technique
The ground such as peculiar to vessel, military or mobile power station that the engineering field construction is used and plateau, hospital, airport often be unable to do without diesel generating set.Diesel generating set is indispensable in China's economy and national defense construction, its demand is very large.Coupling between diesel engine and generator, although it is less to account for the share of unit cost, its effect is but very important, domestic and international project circle is all paid special attention to this field always.
Coupling between present diesel engine and generator, great majority are metallic laminations coupling.Because metallic laminations coupling and rigid coupling and the flexible coupling that contains rubber element are compared, have that compensation principal and subordinate axle shaft axis excursion capability is strong, torsional stiffness large, adapt at a high speed, without lubricated and maintenance, the advantage such as adaptability for working condition is good, the vibration and noise reducing performance is good.It has the trend that replaces gear coupling.
The developed countries such as American and Britain, as far back as last century the eighties just in the diesel generator set product, be widely used the metallic laminations coupling.
China until last century the nineties just really start to use the metallic laminations coupling latter stage in the diesel generator set product.
To so far, metallic laminations coupling and the Power generator fan of domestic and international disclosed diesel generating set is two parts that separate, the body of shaft sleeve parts as fan blade or coupling lamination arranged, the axial dimension that not only makes unit is long, unit weight increases the weight of, volume strengthens, and part processing, assembling all many several procedures.
As can be seen here, if can be integrated into parts to the coupling of diesel generating set and Power generator fan, the length of at least one axle sleeve of unit axial dimension will be shortened, and, the quantity of processing accessories and the quantity of assembly process have also been reduced, reduce cost of production, shortened the unit manufacturing cycle.

Summary of the invention
The technical problem to be solved in the present invention be a kind of diesel generating set of invention use with the integrated flexible laminated membrane coupling of fan height.
Technological scheme of the present invention is: in diesel generator rotor assembly parts, save the axle sleeve that the coupling lamination is installed on generator, shorten the axial dimension of generator rotor shaft, on fan shaft sleeve, increase screw hole, directly the coupling lamination is fixed on the axle sleeve of fan.
Like this after the change, can not affect the service behaviour of fan and coupling, because diesel generator is mainly to come cooled electric generator inside by air draft radially, outside air from the generator afterbody be inhaled into, along axial flow to the generator front end, again through passing through fan turn 90 °, from radially flowing out; The coupling lamination is to rely on the resiliently deformable of self to carry out work, as long as it and fan stiffening rib, blade have 5mm and enough gap, can not interfere.
Certainly, the gap of coupling lamination and fan stiffening rib, blade, also to guarantee fan stiffening rib, blade not with diesel engine on any part interfere.
The invention has the beneficial effects as follows: by the design of change diesel generator rotor assembly parts, shortened the axial dimension of alternator shaft, saved the axle sleeve that the coupling lamination is installed, made the direct integrated installation of coupling lamination on fan shaft sleeve; Not only reduced the quantity of processing unit part and assembly process quantity, reduced cost of production, shortened the unit manufacturing cycle, but also shortened unit axial dimension, alleviated the unit gross weight.
The accompanying drawing explanation
Accompanying drawing 1 be diesel generating set that use with the plan view integrated flexible laminated membrane coupling of fan height.
1: blade; 2: axle sleeve; 3: rotating shaft; 4: flat key; 5: stiffening rib; 6: baffle plate; 7: screw; 8: screw; 9: lamination.
Fan blade 1 is welded on axle sleeve 2; Axle sleeve 2 connects by flat key 4 with alternator shaft 3; Stiffening rib 5 is welded on the outer end of blade 1; Lamination 9 is crushed on the end face of axle sleeve 2 by screw 8; Baffle plate 6 is crushed on the end face of lamination 9 by screw 7.
Accompanying drawing 2 be diesel generating set that use with the left view integrated flexible laminated membrane coupling of fan height.

Concrete implementing measure
The present invention is further described below in conjunction with drawings and Examples.
The specific embodiment of the present invention is: in diesel generator rotor assembly parts, as shown in Figure 1, fan blade 1 is welded on axle sleeve 2; Axle sleeve 2 connects by flat key 4 with alternator shaft 3; Stiffening rib 5 is welded on the outer end of blade 1; Lamination 9 is crushed on the end face of axle sleeve 2 by screw 8; Baffle plate 6 is crushed on the end face of lamination 9 by screw 7.
That is to say, save the axle sleeve that the coupling lamination is installed on generator, shorten the axial dimension of generator rotor shaft, increase screw hole on fan shaft sleeve 2, directly coupling lamination 9 is fixed on the axle sleeve 2 of fan.
Like this after the change, can not affect the service behaviour of fan and coupling, because diesel generator is mainly to come cooled electric generator inside by air draft radially, outside air from the generator afterbody be inhaled into, along axial flow to the generator front end, again through passing through fan turn 90 °, from radially flowing out; The coupling lamination is to rely on the resiliently deformable of self to carry out work, as long as it and fan stiffening rib, blade have 5mm and enough gap, can not interfere.
Certainly, the gap of coupling lamination and fan stiffening rib, blade, also to guarantee fan stiffening rib, blade not with diesel engine on any part interfere.
