Description
Technical field
The utility model belongs to technical field of generators, and in particular to a kind of generator amature shaft assembly.
Background technology
The rotor of generator is arranged on armature spindle, the bent axle connection of armature spindle and engine, rotor is driven by bent axle
Axle is rotated, and generating is realized so as to drive rotor cutting magnetic induction line.Whether generator or engine, in the course of the work all
Substantial amounts of heat can be produced, typically in order to reduce noise during engine work, is also equipped with silencer on the engine, this disappears
Sound device can equally produce heat at work, and in order to radiate, prior art is at the big end of armature spindle（One end of bent axle is installed）
Fan is installed, but the fan mainly carries out cooling to engine and silencer, to the cooling effect of generator compared with
Difference, it is too high to easily cause generator unit stator winding temperature at work, influences generator performance.
Utility model content
For above-mentioned deficiency of the prior art, the utility model main purpose is to provide a kind of generator rotor shaft group
Part, it is advantageous to the cooling of generator, ensures generator operation performance.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of generator amature shaft assembly, including armature spindle and fan, in addition to adapter sleeve, the front end of the armature spindle are opened
Provided with keyway；The adapter sleeve is the tube structure being engaged with armature spindle front end, is provided with and keyway phase in the inwall of adapter sleeve
The projection of cooperation, adapter sleeve are fixed on armature spindle front end with armature spindle by the cooperation of projection and keyway；The fan is arranged
On adapter sleeve.
Further, the end of the adapter sleeve radially extends to it, forms the stopper for protruding from adapter sleeve surface, and fan leads to
Cross and be bolted in the stopper of adapter sleeve.
Further, the big end of the armature spindle offers the connecting hole for bent axle connection, and the connecting hole is along armature spindle axle
To open up and with armature spindle on the same axis；The big end of the armature spindle and it is circumferentially with cave inward, ring along armature spindle
Shape groove, offers pin-and-hole in groove, and the pin-and-hole is opened up along rotor Axial and radial and one end of pin-and-hole communicates with connecting hole；It is bent
In the output end insertion connecting hole of axle, sell through the end of pin-and-hole and pin and be stuck on bent axle.
Further, the connecting hole is shoulder hole, and the big footpath section of shoulder hole is taper hole structure.
Further, the pin-and-hole is two, and two pin-and-holes are symmetrical arranged.
Relative to prior art, the utility model has the advantages that：
The utility model cools down beneficial to generator by the way that fan to be installed on to the front end of armature spindle, ensures to generate electricity
Machine service behaviour.In the utility model, fan first cools down to the less generator of caloric value, then engine is carried out cold
But, finally cooling is arranged on the silencer that caloric value is larger above engine, and cooling order is reasonable, good cooling results, avoids
The drawbacks of finally cooling down the less generator of caloric value in the prior art and causing generator cooling effect bad.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Wherein, 1 is armature spindle, and 2 be groove, and 3 be connecting hole, and 31 be path section, and 32 be big footpath section, and 4 be pin-and-hole, and 5 be key
Groove, 6 be adapter sleeve, and 61 be stopper, and 7 be fan, and 8 be bent axle.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1：Generator amature shaft assembly, including armature spindle 1, fan 7 and adapter sleeve 6, are opened in the front end of armature spindle 1
Provided with keyway 5.Adapter sleeve 6 is the tube structure being engaged with the front end of armature spindle 1, is provided with and the phase of keyway 5 in the inwall of adapter sleeve 6
The projection of cooperation, adapter sleeve 6 are fixed on the front end of armature spindle 1 with armature spindle 1 by the cooperation of projection and keyway 5, and fan is arranged
On adapter sleeve.In the present embodiment, the end of adapter sleeve 6 radially extends to it, forms the stopper for protruding from the surface of adapter sleeve 6
61, fan 7 is bolted in the stopper of adapter sleeve 6
In the present embodiment, one end of armature spindle installation bent axle is big end, and the other end is front end.
The utility model cools down beneficial to generator by the way that fan to be installed on to the front end of armature spindle 1, ensures to generate electricity
Machine service behaviour.In the utility model, fan 7 first cools down to the less generator of caloric value, then engine is carried out cold
But, finally cooling is arranged on the silencer that caloric value is larger above engine, and cooling order is reasonable, good cooling results, avoids
The drawbacks of finally cooling down the less generator of caloric value in the prior art and causing generator cooling effect bad.
Engine crankshaft is easily installed for hair, the connecting hole 3 for bent axle connection, the company are offered at the big end of armature spindle 1
Connect hole 3 axially opened up along armature spindle 1 and with armature spindle 1 on the same axis.At the big end of armature spindle 1 and circumferential along armature spindle 1
Provided with cave inward, annular recess 2, pin-and-hole 4 is offered in groove 2, the pin-and-hole 4 is opened up along the radial direction of armature spindle 1 and pin-and-hole
4 one end communicates with connecting hole 3.In the output end insertion connecting hole 3 of bent axle 8, sell through the end of pin-and-hole 4 and pin and be stuck in song
