The vibrator sealed structural representation that Fig. 3 is prior art;
Reference character: 1-axle; 2-labyrinth lid; The 3-bearing (ball) cover; The 4-disc; 5-the first through hole; The 6-chamber; The 7-circular groove; The 8-toroidal cavity; 9-the second through hole; The 10-third through-hole.
Embodiment
As shown in Figure 1, the invention 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.
Be provided with the first gap between the bearing (ball) cover of close axle and labyrinth lid, as Fig. 1, have the second gap between the disc in bearing (ball) cover and left side; Be provided with first group of circular groove 7 and second group of circular groove in the first gap, 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 between toroidal cavity and chamber and is connected with chamber by toroidal cavity and the first through hole successively.
Bottom of the present invention 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 present invention bottom, referring to Fig. 2, the both sides of the first through-bore axis also are respectively arranged with the second through hole 9 and third through-hole 10, the second through hole and third through-hole all are connected with toroidal cavity, the axis of the axis of the first through hole and the second through hole and the axis of third through-hole are all vertical with the axis of axle, and the axis of the axis of the first through hole and 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.
Usually 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 all is less than the width of toroidal cavity.
Referring to Fig. 1, between bearing (ball) cover and labyrinth lid, v shaped ring also is 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 the disc in bearing (ball) cover and 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 pass through the first through hole under the effect of centrifugal force, the second through hole and third through-hole flow out, in toroidal cavity, the minimizing of oil mass makes the toroidal cavity internal pressure reduce, the lubricant oil that is positioned at second group of circular groove on second gap in toroidal cavity left side and 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, form an annular tooth between two circular grooves, 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 present invention, the angled end of the first through hole, the second through hole and third through-hole all is 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, make lubricant oil repeatedly be got rid of into casing in the passage leaked, and by mechanical structure, realized the sealing to lubricant oil, reaches best sealing effect.
