Description
Technical field
A kind of washing machine monopole asynchronous motor is the utility model is related to, particularly a kind of washing machine with decrease of noise functions
Monopole asynchronous motor.
Background technology
Single-phase asynchronous motor is divided to two kinds of oiliness bearing and ball bearing at present, oiliness bearing motor on washing machine always by
It is extensive to use, due to the axial vibration of rotating shaft when motor operates, cause the sound of oiliness bearing motor bigger than normal, have impact on product
Quality, reduce oiliness bearing motor noise be always in the market a great problem.The factor for influenceing noise has a lot, such as：
Damage in the machining tolerance of component, fit-up gap, operation transport installation process etc..The steel ball seat material that oiliness bearing motor uses
Matter is nitrile rubber, the gap very little between steel ball seat and oiliness bearing, while rotating shaft coordinates tighter, motor height with oiliness bearing
During speed operating, rotating shaft generates the very high axial vibration of frequency, spatial volume and instantaneous air pressure change between steel ball seat and rotating shaft,
Motor air stream and produce empty sound.Therefore, the problem of existing technology is there is loud noise is produced during motor work.
Utility model content
The purpose of this utility model is, there is provided a kind of washing machine monopole asynchronous motor with decrease of noise functions.It has
There is the characteristics of can reducing motor operating noise.
The technical solution of the utility model：Washing machine monopole asynchronous motor with decrease of noise functions, including end cap, end cap
Inner side is provided with bearing, and steel ball seat and rotating shaft are provided with bearing, and steel ball seat one end is in contact with end cap, and the steel ball seat other end is provided with
Steel ball, the steel ball seat outer wall is provided with air channel, and the section of air channel is arc structure；It is additionally provided with the outside of described bearing
Elastic pressure ring, elastic pressure ring are externally provided with oil storage tegillum, and fiber oil clot, described end cap are provided between elastic pressure ring and oil storage tegillum
It is provided with the flanging of fixed oil storage tegillum and elastic pressure ring.
In the foregoing washing machine monopole asynchronous motor with decrease of noise functions, the radius of described air channel is 0.6-
1mm。
In the foregoing washing machine monopole asynchronous motor with decrease of noise functions, described steel ball seat is by nitrile rubber structure
Into.
In the foregoing washing machine monopole asynchronous motor with decrease of noise functions, described oil storage tegillum includes storage fiber
The oil storage tegillum main body of oil clot, oil storage tegillum main body lower end are provided with the fixed edge corresponding with flanging.
Compared with prior art, the utility model in steel ball seat by setting the ventilation that a section is arc structure
Groove, the air between motor steel ball seat and oiliness bearing can effectively be discharged, alleviate because the air velocity of discharge is slow and caused by
Air-flow sound, the sky for improving oiliness bearing motor ring noise, so as to alleviate air pressure change caused by shaft vibration, increase oil-containing
The air-flow velocity of discharge of bearing closing space, reduces noise.Also by setting elastic pressure ring outside bearing, and by end cap
Flanging oil storage tegillum and elastic pressure ring are fixed, convenient installation.In summary, the utility model has and can reduced
The characteristics of motor operating noise.
