Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
The utility model provides a kind of overhang insulation body of series excited machine.Overhang insulation body includes being used for and rotor core
The Part I and the Part II for being connected with armature spindle 10 that 30 end face is engaged, wherein, Part II is arranged to cylinder
Shape and the groove 202 including Part II radially elastic deformation can be made.The diameter of Part II is less than the straight of armature spindle 10
Footpath.In this case, when both overhang insulation body and armature spindle 10 are installed, armature spindle 10 struts Part II,
Enable Part II radially elastic deformation, so elastic compression be sleeved on armature spindle 10.Thus, effectively prevent
Overhang insulation body expands with heat and contract with cold because influenced by ambient temperature, the caused cooperation between armature spindle 10 pine or tension excessively, even
The generation of situations such as cracking.
In a specific embodiment of the present utility model, overhang insulation body is formed as the recessed of bar-shaped trough including multiple
Groove 202, bar-shaped trough axially extend from the end of Part II, and multiple bar-shaped troughs uniformly divide along the circumferential of Part II
Cloth, flexible valve 201 is formed between the adjacent bar-shaped trough of any two.Specifically, groove 202 is multiple parallel to Part II
Axis and along the equally distributed bar-shaped trough of circumference of Part II, form flexible valve between the adjacent bar-shaped trough of any two
201.Groove 202 is alternately distributed the flap-type structure 200 for forming and radially freely can deploying or tighten up with elastic valve 201.Need
Bright, the shape of groove 202 and elastic valve 201 can have any shape, and the number of groove 202 and elastic valve 201 can also
For any amount, as long as being sleeved on armature spindle 10 while the Part II elastic compression of overhang insulation body can be made.It is preferred that
The cross sectional shape of ground, groove 202 and elastic valve 201 is rectangle, and the number of groove 202 and elastic valve 201 is no less than 12.
In this case, when overhang insulation body is influenceed by environment temperature and is expanded with heat and contract with cold, the deflection of Part II can
To be evenly distributed on multiple elastic valves 201, the elastic elastic deformation of valve 201 is to carry out the adjust automatically of elasticity, Jin Erbao
Overhang insulation body has been demonstrate,proved in the case where not being damaged, stable connection is formed between armature spindle 10.
In order to ensure that the end of Part II is fastenedly connected with armature spindle 10, elastic valve 201 includes being connected with Part I
Connection end 2011 and away from connection end 2011 free end 2012.Elastic valve 201 is arranged to from connection end 2011
To free end 2012 towards the journal offset of Part II.That is, the Part II of tubulose has the internal diameter of gradual change.Second
Partial internal diameter is gradually reduced from connection end 2011 to free end 2012.The maximum inner diameter of Part II is connection end
Internal diameter at 2011, the internal diameter are slightly less than the diameter of armature spindle 10.In this case, when armature spindle 10 and overhang insulation body fill
It is interior through being gradually reduced from connection end 2011 to free end 2012 due to flap-type structure 200 with formula, therefore, armature spindle 10
Clamping force between overhang insulation body is become larger by being connected end 2011 to free end 2012.Thereby it is ensured that rotor
It can be fastenedly connected between axle 10 and overhang insulation body.
In addition, installing for convenience, it is to seamlessly transit to connect between end 2011 and free end 2012.That is,
The inner surface of flap-type structure 200 is smooth.Further, the development length of multiple elastic valves 201 can with it is identical can not also
Together, it is preferable that in order to facilitate the manufacture of overhang insulation body, the development length of multiple elastic valves 201 is identical.
In order to ensure flap-type structure 200 in the case of with certain elastic deformability, inner surface and armature spindle 10
Between can sufficiently contact, the ratio of the width of the width of groove 202 and elastic valve 201 is 0.3-1.Specifically, when groove 202
During with the setting negligible amounts of elastic valve 201, the ratio of the width of groove 202 and the width of elastic valve 201 is smaller, close or wait
In 0.3；And when the setting quantity of groove 202 and elastic valve 201 is more, the width of groove 202 and the width of elastic valve 201
Ratio is larger, close to or equal to 1.In addition, overhang insulation body is preferably made up of nylon material.
The utility model additionally provides a kind of series excited machine, and the series excited machine includes armature spindle 10, installed in armature spindle 10
On rotor core 30 and the overhang insulation body installed in 30 axial both ends of rotor core, the overhang insulation body be above-mentioned string
Swash the overhang insulation body of motor, wherein, it is set on armature spindle 10 Part II elastic compression.Further, series excited machine
Including the commutator 40 installed in the one end of armature spindle 10, positioned at one end of the overhang insulation body at the end of armature spindle 10 and rotor core
30 end contact, the other end are extend into the internal diameter of commutator 40.In such a case, it is possible to prevent from being wound on overhang insulation body
On enamel-covered wire enter the clearance space of end insulator and commutator, cause pressure-resistant bad.
In addition, series excited machine also includes the winding 50 being made up of enamel-covered wire.Rotor core 30 includes being formed in rotor core
Multiple rotor core grooves 302 on side face.The Part I of overhang insulation body be provided with can respectively with multiple rotor core grooves
