Abstract
The utility model provides a laminated membrane coupling with a shaft sleeve used for a fan. The laminated membrane coupling with the shaft sleeve used for the fan is used for a diesel generating set. By improving certain components of a rotor assembly of a diesel generator, the axial total length of a rotating shaft of the generator is reduced, a shaft sleeve for mounting a coupling laminated membrane 9 is omitted, the coupling laminated membrane 9 can be directly arranged on a fan shaft sleeve 2, and the coupling laminated membrane 9 and fan blades 1 share the shaft sleeve 2. The number of parts of a machining unit and the number of assembling procedures are reduced, the production cost is also reduced, the manufacturing period of the unit is shortened, the axial size of the unit is reduced, and the total weight of the unit is also reduced.
Description
Technical field
The utility model relates to diesel generating set coupling field, particularly with the flexible laminated membrane coupling of the coaxial cover of fan.
Background technique
The ground such as peculiar to vessel, military or mobile power station that 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, and 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 diesel engine and generator now, great majority are metallic laminations coupling.Because metallic laminations coupling and rigid coupling and containing compared with the flexible coupling of rubber element, 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, 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 diesel generator set product, be widely used metallic laminations coupling.
China until last century the nineties just really start to use metallic laminations coupling latter stage in 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, there is the body of shaft sleeve parts as fan blade or coupling lamination, 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 the coupling of diesel generating set and Power generator fan can be integrated into parts, 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 are also reduced, reduce cost of production, shortened the unit manufacturing cycle.
Summary of the invention
The technical problems to be solved in the utility model be invention a kind of diesel generating set that use with the flexible laminated membrane coupling coaxial cover of fan.
The technical solution of the utility model is: in diesel generator rotor assembly parts, save the axle sleeve that coupling lamination is installed on generator, the axial dimension that shortens generator rotor shaft increases screw hole on fan shaft sleeve, directly coupling lamination is fixed on the axle sleeve of fan.Like this after 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 generator afterbody be inhaled into, along axial flow to generator front end, again through passing through fan turn 90 °, from radially flowing out; Coupling lamination is to rely on self resiliently deformable 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 ensure fan stiffening rib, blade not with diesel engine on any part interfere.
The beneficial effects of the utility model are: by the design of change diesel generator rotor assembly parts, shortened the axial dimension of alternator shaft, saved the axle sleeve that 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 the quantity of assembly process, reduced cost of production, shortened the unit manufacturing cycle, but also shortened unit axial dimension, alleviated unit gross weight.
Brief description of the drawings
Accompanying drawing 1 is diesel generating set plan view that use and the flexible laminated membrane coupling coaxial cover of fan.
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 is diesel generating set left views that use and the flexible laminated membrane coupling coaxial cover of fan.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment of the present utility model 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 coupling lamination is installed on generator, shorten the axial dimension of generator rotor shaft, on fan shaft sleeve 2, increase screw hole, directly coupling lamination 9 is fixed on the axle sleeve 2 of fan.
Like this after 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 generator afterbody be inhaled into, along axial flow to generator front end, again through passing through fan turn 90 °, from radially flowing out; Coupling lamination is to rely on self resiliently deformable 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 ensure fan stiffening rib, blade not with diesel engine on any part interfere.
