Summary of the invention:
The purpose of this utility model provides a kind of new waterproof structure of motor, compactness rational in infrastructure, and the waterproof dustproof effect is better, effectively improves the working life of motor and motor bearings.
The purpose of this utility model is achieved by following technical proposals.
A kind of new waterproof structure of motor, comprise end cap, in the middle of the end face of the end cap outside, protrude big boss and small boss, thereby in the middle of the big boss is hollow formation cavity, and small boss is positioned at the cavity the inside, has axis hole on small boss the inside, end cap, axis hole is passed in rotating shaft, be with the static seal circle in the outside of small boss, dynamic seal ring is installed in rotating shaft, dynamic seal ring cooperates with the static seal circle.
Above-mentioned described dynamic seal ring is positioned at the cavity the inside.
Horn mouth is formed on above-mentioned described static seal circle top, and dynamic seal ring protrudes hollow cover body, and horn mouth is nested in the cover body the inside, and above-mentioned described horn mouth top and cover body inwall are fitted and sealed.
In the above-mentioned described rotating shaft draw-in groove is set, dynamic seal ring is locked in the draw-in groove the inside.
Above-mentioned described big boss and small boss are concentric, and the height that small boss protrudes is less than big boss.
Above-mentioned described bearing pedestal is equipped with bearing at the inboard bearing pedestal that protrudes of end cap, and the rotating shaft mounting support is on bearing.
Above-mentioned described static seal circle is tubaeform, and dynamic seal ring is a bowl-type.
The internal face of above-mentioned described big boss is a taper seat.
The utility model compared with prior art, has following effect: 1) protrude big boss and small boss in the end cap arranged outside, big boss itself plays the effect of the first road mine dam, arrive small boss even there is moisture content to enter cavity, be with the static seal circle in the outside of small boss, the static seal circle cooperates the axis hole that stops moisture content to enter the small boss the inside with dynamic seal ring, form the effect of the second road mine dam, dynamic seal ring is installed in the rotating shaft, and rotating shaft and dynamic seal ring closely cooperate, and moisture content can not leak into axis hole along rotating shaft, form the effect of the 3rd road mine dam, so compactness rational in infrastructure, the waterproof dustproof effect is better, effectively improves the working life of motor and motor bearings.2) horn mouth is formed on static seal circle top, and dynamic seal ring protrudes hollow cover body, and horn mouth is nested in the cover body the inside, and above-mentioned described horn mouth top and cover body inwall are fitted and sealed compactness rational in infrastructure; 3) big boss and small boss are concentric, and the height that small boss protrudes is less than big boss, and is rationally distributed; 4) internal face of big boss is a taper seat, helps moisture content and discharges from cavity.
Description of drawings:
Fig. 1 is the principle schematic of conventional motors waterproof construction.
Fig. 2 is a structure cutaway view of the present utility model;
Fig. 3 is the A-A cutaway view of Fig. 2.
Embodiment:
Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.
As Fig. 2, shown in Figure 3, a kind of new waterproof structure of motor, comprise end cap 1, in the middle of end cap 1 outside end face, protrude big boss 2 and small boss 3, thereby be hollow formation cavity 4 in the middle of the big boss 2, small boss 3 is positioned at cavity 4 the insides, have axis hole 5 on small boss 3 the insides, end cap 1, axis hole 5 is passed in rotating shaft 6, is with static seal circle 7 in the outside of small boss 3, dynamic seal ring 8 is installed in rotating shaft 6, and dynamic seal ring 8 is positioned at cavity 4 the insides and cooperates with static seal circle 7.Horn mouth 71 is formed on described static seal circle 7 tops, dynamic seal ring 8 protrudes hollow cover body 81, horn mouth 71 is nested in cover body 81 the insides, horn mouth 71 tops and cover body 81 inwalls are fitted and are sealed, draw-in groove 61 is set in the rotating shaft 6, dynamic seal ring 8 is locked in draw-in groove 61 the insides, and big boss 2 and small boss 3 are concentric, and the height that small boss 3 protrudes is less than big boss 2.Protrude bearing pedestal 10 in the middle of end cap 1 inner side end, bearing pedestal 10 is equipped with bearing 11, and rotating shaft 6 mounting supports are on bearing 11, static seal circle 7 is tubaeform, and dynamic seal ring 8 is bowl-types, and the internal face 9 of big boss 2 is taper seats, form certain gradient, be convenient to discharge moisture content.
Principle of the present utility model: protrude big boss 2 and small boss 3 in end cap 1 arranged outside, big boss 2 itself plays the effect of the first road mine dam, arrive small boss 3 even there is moisture content to enter cavity 4, be with static seal circle 7 in the outside of small boss 3, horn mouth 71 is formed on described static seal circle 7 tops, dynamic seal ring 8 protrudes hollow cover body 81, horn mouth 71 is nested in cover body 81 the insides, horn mouth 71 tops and cover body 81 inwalls are fitted and are sealed, static seal circle 7 effectively cooperates the axis hole 5 that stops moisture content to enter small boss 3 the insides with dynamic seal ring 7, form the effect of the second road mine dam, dynamic seal ring 8 is installed in the rotating shaft 6, rotating shaft 6 closely cooperates with dynamic seal ring 8, moisture content can not leak into axis hole along rotating shaft, forms the effect of the 3rd road mine dam, therefore compactness rational in infrastructure, the waterproof dustproof effect is better, effectively improves the working life of motor and motor bearings.
