Abstract
The utility model discloses a generator set, which comprises an engine, a fan, a generator stator, an outer end cover of a generator, an inner end cover of the generator and a generator rotor. The generator rotor is rotated relative to the generator stator, and the inner end cover of the generator is fixed at one end of the engine. A rotation shaft of the engine extends out the inner end cover of the generator to be connected with one end of a spindle of the generator rotor. The generator stator is fixed on the outer end cover of the generator, and the generator stator and the generator rotor are both arranged inside the outer end cover of the generator. The outer end cover of the generator is fixed on the inner end cover of the generator, the fan is movably sleeved with an end extending out of the rotation shaft of the engine, a left end surface of the fan is in contact with the spindle of the generator rotor and fixed on the spindle through a connecting sleeve, and the connecting sleeve is arranged at an end of the spindle close to the fan in a sleeve mode.
Description
Technical field
The utility model relates to a kind of generating set, particularly a kind of generating set of being made up of generator and engine.
Background technology
Generating set is made up of engine and generator usually, be volume, the minimizing raw materials consumption that reduces generating set, usually be one with engine and generator designs, be about to the rotor of generator or an end of the rotation axis that stator is directly installed on engine, that have even direct is one with the rotor of generator and the flywheel design of engine.So both reduce raw-material use amount, reduced the shared space of whole unit again.When generating set was worked, engine and generator all can produce a large amount of heats.This just needs to use the fan forced heat radiation.
At present, normally the end at generating set increases radiator fan, plays the effect of heat radiation.But during owing to generating set work, generator and engine all can produce heat, prior art links together both can make heat accumulation, both heats can only loose from the surface row that cold wind flows, more heat then may accumulate in both joint portions, the heat that distributes when being not enough to get rid of generator and engine operation, radiating efficiency is low.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of generating set of good heat dissipation effect.
The technical solution of the utility model is as follows: a kind of generating set, comprise engine, fan, generator unit stator, generator outer end cap, generator inner end cap and with respect to generator unit stator generator rotated rotor, described generator inner end cap is fixed on an end of engine; The rotation axis of described engine stretches out after the generator inner end cap with an end of the rotating shaft of generator amature and is connected; Described generator unit stator is fixed on the generator outer end cap, and described generator unit stator and generator amature all are positioned at the generator outer end cap; Described generator outer end cap is fixed on the generator inner end cap, described fan kink is at the external part of the rotation axis of engine, the left side of described fan contacts with the rotating shaft of generator amature, the left side of described fan is fixed in the rotating shaft by adapter sleeve, and described adapter sleeve is sleeved on the end of rotating shaft near fan.
Adopt technique scheme, fan is arranged between generator amature and the engine, cooled electric generator when cooling air flows through the generator stator-rotator slit on the one hand; On the other hand, played the transmission that intercepts heat between generator and the engine, made heat can not assemble in both joint portions, radiating effect is better.
In order to make radiating effect better, the left side of described generator outer end cap is provided with dust cover.
In technique scheme, described adapter sleeve is fixed in the rotating shaft by interference fit.
Beneficial effect: the utility model is reasonable in design, simple in structure, enforcement is easy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model is by engine 3, fan 6, generator unit stator 2, generator amature 4, generator outer end cap 1 and generator inner end cap 8 are formed, as shown in Figure 1, the fit of generating set of the present utility model is for being followed successively by engine 3 from right to left, generator the inner 8, fan 6, generator amature 4, generator unit stator 2, generator outer end cap 1, described engine 3, fan 6, generator amature 4, generator unit stator 2 and generator outer end cap 1 all adopt prior art, do not do at this and to give unnecessary details, described generator inner end cap 8 is fixed on an end of generator 3, the rotation axis 3a of described engine 3 stretches out generator inner end cap 8 backs and is connected with the end of the rotating shaft 4a of generator amature 4, inserting a bolt from the left end of the rotating shaft 4a of generator amature 4 is fixed together the rotation axis 3a of engine 3 and the rotating shaft 4a of generator amature 4, described generator unit stator 2 is fixed on the generator outer end cap 1, described generator unit stator 2 and generator amature 4 all are positioned at generator outer end cap 1, described generator outer end cap 1 is fixed on the generator inner end cap 8, described fan 6 kinks are at the external part of the rotation axis 3a of engine 3, the rotating shaft 4a of the left side of described fan 6 and generator amature 4 contacts, and be fixed on the rotating shaft 4a by adapter sleeve 5, described adapter sleeve 5 is fixed on the end of the rotating shaft 4a of generator amature 4 near fan 6 by interference fit, described fan 6 is by being bolted on the adapter sleeve 5, and the left side of described generator outer end cap 1 is provided with dust cover 7.
When engine 3 rotates, drive generator amature 4 and rotate, generator amature 4 rotates the back and drives fan 6 high speed rotating, and fan 6 is used for cooled electric generator and engine 3 on the one hand, play the effect of trap heat on the other hand, prevent that heat is in the gathering of the joint portion of generator and engine 3.
