The cross section of above-mentioned the first through hole, the second through hole and third through-hole is circle, and the diameter of the first through hole, the second through hole and third through-hole is all less than the width of toroidal cavity.
The quantity of above-mentioned first group of circular groove and second group of circular groove is 3-4.
The utlity model has following advantage:
On labyrinth of the present utility model lid, bearing (ball) cover, be designed with two groups of circular grooves, these two groups of ring channel structures are simple, convenient processing and manufacture, by labyrinth cover and bearing (ball) cover between toroidal cavity structure, effectively stoped the leakage of lubricant oil.
In addition, the utility model is less demanding to the hardness of bearing (ball) cover and surface roughness, and the axial activity of labyrinth lid is less, thereby stability of the present utility model is higher.By simple structural design, reached sealing effect, reduced difficulty of processing, saved cost of parts and maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to view;
Fig. 3 is the vibrator sealed structural representation of prior art;
Reference character: 1-axle; 2-labyrinth lid; 3-bearing (ball) cover; 4-disc; 5-the first through hole; 6-chamber; 7-circular groove; 8-toroidal cavity; 9-the second through hole; 10-third through-hole.
Embodiment
As shown in Figure 1, the utility model provides a kind of vibrator sealing configuration, comprise axle 1, labyrinth lid 2, bearing (ball) cover 3, disc 4 and casing, the periphery of axle is socketed with respectively disc and labyrinth lid, the periphery of labyrinth lid is socketed with bearing (ball) cover, equal interference fit between labyrinth lid and axle and between disc and axle; Bearing (ball) cover is fixed on casing and between disc and labyrinth lid, is provided with chamber 6 in casing.
Between the bearing (ball) cover of close axle and labyrinth lid, be provided with the first gap, as Fig. 1, between bearing (ball) cover and the disc in left side, have the second gap; In the first gap, be provided with first group of circular groove 7 and second group of circular groove, first group of circular groove is arranged on labyrinth and covers, and second group of circular groove is arranged on bearing (ball) cover or labyrinth covers; The bearing (ball) cover relative with first group of circular groove is provided with toroidal cavity 8, is provided with 5, the first groups of circular grooves of the first through hole and by toroidal cavity and the first through hole, is connected with chamber successively between toroidal cavity and chamber.
Bottom of the present utility model is provided with attachment face, during vibrator works, and the angle that the attachment face of bottom is general and horizontal plane keeps 30 degree-60 to spend, preferably 45 degree.In order to meet different matching requirements, the first through-bore axis is vertical with the attachment face of the utility model bottom, referring to Fig. 2, the both sides of the first through-bore axis are also respectively arranged with the second through hole 9 and third through-hole 10, the second through hole and third through-hole are all connected with toroidal cavity, the axis of the first through hole is all vertical with the axis of axle with the axis of the second through hole and the axis of third through-hole, and the axis of the first through hole and the axis of the second through hole and the axis angle of third through-hole are 30 degree-60 degree, preferably 45 degree.
During vibrator works, generally attachment face and horizontal plane are kept to 45 degree angles, now, the axis of the second through hole or the axis of third through-hole are vertical with horizontal plane, and now, the through hole vertical with horizontal plane is in best leak position.
Conventionally the cross section of the first through hole, the second through hole and third through-hole is set to circle, and the diameter of the first through hole, the second through hole and third through-hole is all less than the width of toroidal cavity.
Referring to Fig. 1, between bearing (ball) cover and labyrinth lid, v shaped ring is also housed, when axle drives labyrinth lid rotation, in chamber due to casing, lubricant oil is housed, in chamber, a small amount of lubricant oil can enter into the first gap by the second gap between bearing (ball) cover and the disc in left side, then enter into toroidal cavity, because being arranged on labyrinth, first group of circular groove cover, therefore, first group of circular groove also can rotate along with the rotation of axle, under the turning effort of first group of circular groove, stick to first group of lubricant oil on circular groove and under the effect of centrifugal force, pass through the first through hole, the second through hole and third through-hole flow out, in toroidal cavity, the minimizing of oil mass reduces toroidal cavity internal pressure, the lubricant oil that is positioned at second gap in toroidal cavity left side and second group of circular groove on right side will be inhaled into toroidal cavity, and then by the first through hole, the second through hole and third through-hole are thrown out of, iterative cycles like this.
First group of circular groove quantity is 2-5, preferably 3-4, between two circular grooves, form an annular tooth, annular tooth quantity is more, the pressure that during work, toroidal cavity produces is lower, lubricant oil unnecessary in gap just can enter toroidal cavity, finally by the first through hole, the second through hole and third through-hole, enters chamber.
For the ease of processing the utility model, the angled end of the first through hole, the second through hole and third through-hole is all connected in same port, and the first through hole, the second through hole and third through-hole are connected with toroidal cavity by described port.
Above sealing principle is repeatedly got rid of into casing lubricant oil in the passage leaking, and by mechanical structure, has realized the sealing to lubricant oil, reaches best sealing effect.
