Description
Technical field
The utility model relates to motor for washer oiliness bearing technical field, particularly relates to a kind of oil-bearing structure for motor for washer.
Background technology
The useful life of oiliness bearing is main relevant to the oil mass of its inside, due in production technology to the demand of oiliness bearing working life, around oiliness bearing, often add deposit oil, by laying in oil, oiliness bearing is refueled, thus extend the useful life of oiliness bearing.But in fact deposit oil is also little on the impact in oiliness bearing life-span, because, oiliness bearing is sintered by hollow powders structure to form, oil content is usually between 15%-18%, oiliness bearing internal holes is very little, the mode of vacuum oil suction must be used the air in bearing could to be extracted out, thus the oil outside bearing is drawn into oiliness bearing inner space by the negative pressure relying on vacuum to produce, make body surface oil and dose oil to be generally useless oil, effectively can not improve the useful life of oiliness bearing.
The patent No. be CN202108879U patent discloses a kind of composite type oiliness bearing, the shell of oiliness bearing is made square or regular hexagon, to prevent oiliness bearing from being driven transfer by axle, causes Housing failure, thus extend useful life of oiliness bearing.This patent not from the viewpoint of the inner oil mass loss of reduction oiliness bearing to extend the working life of oiliness bearing, therefore, increase effect the useful life of oiliness bearing and not obvious.The patent No. be 200520013060.3 patent discloses a kind of gradient oiliness bearing, the aperture of oiliness bearing is arranged by gradient shape, aperture is increased to inner ring successively by outer ring, thus improve the carrying energy of oiliness bearing, but this structure manufactures complicated, and do not set about the useful life of improving oiliness bearing from the inner oil mass loss aspect of reduction oiliness bearing.
Utility model content
The utility model, for prior art Problems existing, provides a kind of oil-bearing structure for motor for washer improving oiliness bearing useful life.
The utility model solves the technical scheme that its technical problem adopts: a kind of oil-bearing structure for motor for washer, comprises rotor axis of electric, oiliness bearing, electric motor end cap and bearing positioning gland; The body cavity holding described rotor axis of electric and rotate is had in described oiliness bearing body; Described oiliness bearing and described rotor axis of electric contact-making surface have and increase longevity portion.
Rotor axis of electric of the present utility model and oiliness bearing are when relative motion, and contact area is larger, and loss is larger.Therefore, the contact area that can reduce rotor axis of electric and oiliness bearing is come, and reduces the loss of oiliness bearing, increases the utilization rate of lubricating oil, thus improves the useful life of oiliness bearing.
Further, the radius in described increasing longevity portion is greater than the radius of described body cavity; On the axial direction of described armature spindle, the length in described increasing longevity portion is the half of described cavity length.
Further, described oiliness bearing outer wall, described electric motor end cap inwall, and described bearing positioning gland pressing composition accumulator.
Further, oil storage material is equipped with in described accumulator inside.
Further, described oil storage material is wool felt.
Further, described oil storage material is nanosponges.
Further, described electric motor end cap has the holding section be fixed by described bearing positioning gland.
Further, described holding section is U-shaped.
The contact area of the utility model by adopting increasing longevity portion to reduce rotor axis of electric and oiliness bearing, thus improve the useful life of motor for washer oiliness bearing.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of oil-bearing structure for motor for washer of the utility model;
Fig. 2 is the fundamental diagram of oiliness bearing in Fig. 1.
Wherein: 1, rotor axis of electric, 2, oiliness bearing, 3, increase longevity portion, 4, electric motor end cap, 5, bearing positioning gland.
Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of oil-bearing structure for motor for washer, comprises rotor axis of electric 1, oiliness bearing 2, electric motor end cap 4 and bearing positioning gland 5; The body cavity holding described rotor axis of electric 1 and rotate is had in described oiliness bearing 2 body; Described oiliness bearing 2 and described rotor axis of electric 1 contact-making surface have and increase longevity portion 3.Rotor axis of electric 1, when high-speed cruising, due to axle surface and the relative motion of bearing surface, forms a negative pressuren zone, by the sucking-off from oiliness bearing of the oil in oiliness bearing in the front end of axle and bearing surface.The oil of sucking-off in oiliness bearing 2 forms rapidly an oil film area at axle and bearing surface, and axle and bearing separate and isolate by this oil film area, thus reduce the friction between axle and bearing.The contact area that the utility model can reduce rotor axis of electric and oiliness bearing by increasing longevity portion 3 is come, and reduces the loss of oiliness bearing, increases the utilization rate of lubricating oil, thus improves the useful life of oiliness bearing.
In addition, oiliness bearing 2 is done large 0.5 cm near rotor axis of electric 1 side half length internal bore radius, the contact area of such axle and oiliness bearing is original half, the wearing and tearing of axle and bearing also reduce half, comparatively speaking, the oil content of oiliness bearing is just doubled, and the life-span of oiliness bearing is just doubled.Moreover, when oiliness bearing 2 is on the axial direction of armature spindle 1, after interior table contact length reduces half, the finishing shape of bearing is more accurate, the contact of bearing and axle evenly, friction and the vibration of bearing and axle are less, the heating of bearing is also little, and the life-span of bearing increases.
In addition, because bearing life significantly increases, the oil storage material in accumulator can be wool felt or nanosponges, and motor can meet the service requirement of more high life, and motor cost reduces, and the life-span increases.
In addition, rotor axis of electric 1 rotates in the inner chamber of oiliness bearing 2 externally provides torque, realizes the output of motor kinetic energy.Oiliness bearing 2 supporting motor armature spindle 1, provides lubricating oil film, and rotor can normally be rotated.After rotor axis of electric 1 contacts with oiliness bearing 2, lubricating oil flows back to Bearing inner from axle and bearing touch surface rear end, forms primary Ioops in inside simultaneously, oil is delivered to the oiliness bearing surface of axle pivot head, forms a duty cycle.Oiliness bearing 2 is exactly constantly at axle core running front end sucking-off oil, simultaneously continuous from the rear end suction oil that axle runs again, this process of iterative cycles.
In addition, electric motor end cap 4 has the U-shaped holding section be fixed by bearing positioning gland 5, and electric motor end cap 4 has the effect of positioning motor oiliness bearing; Oiliness bearing 2 and electric motor end cap 4 are located by bearing positioning gland 5 completely, guarantee that the relative position of bearing and end cap immobilizes.
The utility model has can improve the advantages such as motor for washer oiliness bearing useful life.
