Description
【Technical field】
The present invention relates to motor, more particularly to small-sized or micromachine, the invention further relates to be used for small-sized or micro electric
The wave spring washer of machine.
【Background technology】
Small-sized or micromachine all plays critically important effect in every field, and its reliability is especially paid close attention to and weight by people
Depending on.Prior art is small-sized or stator core of micromachine is fixed to include being fixed with bolt and press-fited with cold and hot with shell；According to
Bolt is fixed, and stator core has to out a bolt hole, and so, motor will increase the yoke portion size of stator core, same outer
Shell will also design the bolt hole of fixed stator iron core, and shell sizes also will be increased accordingly, can so increased the volume of motor；
If cold and hot press-fit, stator core and the shell magnitude of interference less, are easy to loosen after shell is heated, and actually stator core is outer
The inner surface of surface and shell is the false interference of high point contact, is especially run up in long-time in small-sized or micromachine
Cheng Shi, temperature is higher, and shell expansion, stator core changes position in torsion and vibrations, reduces the reliability of motor,
Whole motor is set to there is potential safety hazard.
【The content of the invention】
The technical problem to be solved in the present invention is to avoid above-mentioned the deficiencies in the prior art part and provide a kind of safety

Rotating shaft is rotatably arranged on the front and back ends lid by the forward and backward bearing, and the rotating shaft front end is from the drive end bearing bracket
Heart through hole stretches out；Described small-sized or micromachine also includes positioning, damping and prevents the stator core loose shift of stator module
Wave spring washer, the wave spring washer include one circle undulate rise and fall and irregular narrow all flange portions, and should
The central through hole that narrow all flange portions surround；The wave spring washer is arranged between the rear end cap and stator core, wherein
Narrow all flange portions of the wave spring washer are compressed between the end face of the rear end cap and the end face of stator core, described
The inner peripheral surface of wave spring washer will not interfere with the stator winding of stator module, that is to say, that the center of wave spring washer
Overall size of the through hole inside dimensions more than the stator winding of stator module.When small-sized or micromachine works, temperature
Raise, each end cap can expand, were it not for wave spring washer, stator core can change position in torsion and vibrations,
And after the wave spring washer is provided with, making stator core have axial pretightening and circumferentially positioned, stator core is in motor work
When making, even if having torsion and vibrations, the position of stator core will not change.Wave spring washer prevents the stator ferrum
Core changes position in torsion and vibrations, serves the effect of positioning and damping.
The one of narrow all flange portions of the wave spring washer faces out and is provided with multiple first spacing block sets, accordingly, institute
State stator core outer surface and be provided be adapted with first spacing block set, the stator stopper slot that quantity is equal；It is small-sized or micro-
After the assembling of type motor, each first spacing block set in narrow all flange portions of the wave spring washer is corresponding positioned at the stator core
Stator stopper slot in.
First spacing block set is three, and the stator stopper slot is three.
Another the facing out in narrow all flange portions of the wave spring washer is provided with second spacing block set, accordingly,
The rear end cap is provided with a rear end cap stopper slot being adapted with second spacing block set；The assembling of small-sized or micromachine
Afterwards, second spacing block set in narrow all flange portions of the wave spring washer is located in the rear end cap stopper slot of the rear end cap.
The present invention also provides a kind of wave spring washer on small-sized or micromachine, including a circle undulate rises
Lie prostrate and irregular narrow all flange portions, and the central through hole that narrow all flange portions surround.The narrow week of the wave spring washer
The one of flange portion faces out and is provided with multiple first spacing block sets.First spacing block set is three.The wave spring washer
