Abstract
The utility model discloses a kind of generator rotor shaft of anti-slip, including rotor shaft body, offer the connecting hole connected for bent axle in one end of body, the connecting hole axially opened up along body and with body on the same axis；Cave inward, annular recess is circumferentially with one end of body and along body, pin-and-hole is opened up in groove, the pin-and-hole is radially opened up along body and one end of pin-and-hole is communicated with connecting hole；The utility model after crankshaft installed is in connecting hole, is inserted pins into pin-and-hole, the end of pin is stuck on bent axle, so as to prevent bent axle from operationally skidding due to setting connecting hole and pin-and-hole in one end of body.
Description
Technical field
The utility model belongs to technical field of generators, and in particular to a kind of generator rotor shaft of anti-slip.
Background technology
The rotor of generator is arranged on armature spindle, the bent axle connection of armature spindle and engine, and rotor is driven by bent axle
Axle is rotated, so as to drive rotor cutting magnetic induction line and realize generating.In the prior art, engine crankshaft, which is typically directly installed on, turns
On sub- axle, it easily skids in the course of the work, influences generator operation performance.
Utility model content
For above-mentioned deficiency of the prior art, the utility model main purpose is to provide a kind of generator of anti-slip and turned
Sub- axle.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of generator rotor shaft of anti-slip, including rotor shaft body, are offered in one end of body for bent axle connection
Connecting hole, the connecting hole axially opened up along body and with body on the same axis；In one end of body and circumferential along body
Provided with cave inward, annular recess, pin-and-hole is opened up in groove, the pin-and-hole along body radially open up and pin-and-hole one end with
Connecting hole is communicated.
Further, the pin-and-hole is two, and two pin-and-holes are symmetrical arranged.
Further, the connecting hole is shoulder hole, and the big footpath section of shoulder hole is taper hole.
Further, the other end of the body is further opened with the keyway for installing fan.
Relative to prior art, the utility model has the advantages that：
The utility model in one end of body due to setting connecting hole and pin-and-hole, after crankshaft installed is in connecting hole, by pin
Insert in pin-and-hole, the end of pin is stuck on bent axle, so as to prevent bent axle from operationally skidding.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 is body, 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 keyway.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig. 1：The armature spindle for preventing bent axle from skidding, including rotor shaft body 1, are offered in one end of body 1 for bent
The connecting hole 3 of axle connection, the connecting hole 3 axially opened up along body 1 and with body 1 on the same axis.In use, bent axle
In output end insertion connecting hole 3, driving armature spindle is rotated.Inserted for the ease of bent axle and prevent from skidding during its work, this implementation
In example, connecting hole 3 is shoulder hole, and the path section 31 of shoulder hole is aperture identical straight hole structure, and the big footpath section 32 of shoulder hole is
Taper hole structure, the aperture of its arrival end is more than the aperture of connection end（Connection end is the big footpath section of shoulder hole and path section junction）.
Cave inward, annular recess 2 is circumferentially with one end of body 1 and along body 1, pin is offered in groove 2
Hole 4, the pin-and-hole 4 is radially opened up along body and one end of pin-and-hole 4 is communicated with connecting hole 3.In the present embodiment, one end of pin-and-hole 4 with
The big footpath section 32 of connecting hole 3 is communicated.After in the output end insertion connecting hole 3 of bent axle, insert pins into pin-and-hole 4, the end of pin
It is stuck on bent axle, so as to prevent bent axle from operationally skidding.
Pin-and-hole 4 is settable one, can also be symmetrical arranged 2, in the present embodiment, pin-and-hole 4 is two, and two pin-and-holes 4 are symmetrical
Set.
For the ease of generator heat-radiation, the keyway 5 for installing fan is further opened with the other end of rotor shaft body 1,
So as to which fan to be installed on to the front end of armature spindle.
Finally it should be noted that above example is only to illustrate the technical solution of the utility model rather than restriction technologies
Scheme, although the utility model is described in detail with reference to preferred embodiment by applicant, one of ordinary skill in the art
It should be appreciated that those modify or equivalent substitution to the technical solution of the utility model, without departing from the technical program
Objective and scope, all should cover among right of the present utility model.
