Description

Horizontal bearing means

Technical field

The utility model relates to a kind of bearing means, especially a kind of horizontal bearing means that is used to prevent leakage of oil.

Background technique

At present, known horizontal type rolling bearing support generally is made up of bearing support, bearing upper cover, end cap, oil sealing etc., and it uses lubricant oil; Lubricant oil can not circulate in the bearing support grease chamber, is static, and such lubricant oil is lubricated not enough with cooling action to bearing; And bearing support is sealed through oil sealing; Such oil sealing use a period of time will leakage of oil, cause the bearing oil starvation, damage easily.

The model utility content

The utility model provides a kind of horizontal bearing means, and it can solve the problem of existing horizontal bearing support easy oil leakage.

In order to solve the problems of the technologies described above; The technological scheme that the utility model adopted is: it includes the bearing support that has the grease chamber, is connected bearing upper end cap, bearing, main shaft and bearing (ball) cover that the back forms the Bearing Installation face with bearing support; Bearing Installation is in the Bearing Installation face of bearing support and bearing upper end cap; Described Bearing Installation face is positioned at bearing support and bearing upper end cap two ends, and is gapped between bearing inboard and the bearing support, and the convex shoulder of this gap and bearing support forms the first little grease chamber; Gapped between the bearing outside and the bearing (ball) cover, form the second little grease chamber, there is the oil circuit that is communicated with said grease chamber lower end, the described second little grease chamber, and bearing (ball) cover is formed the sealing of embedding maze type with " U " shape oil ring that entangles main shaft; The band oil ring that stretches in the said grease chamber oil is housed on the said main shaft; Said bearing support is provided with oil groove, and this oil groove is located at the side of said grease chamber, and this side is taken oily side out of for the band oil ring, and the two ends of said oil groove communicate with the described first little grease chamber respectively.

In the technique scheme, scheme is more specifically: be provided with filter screen between said oil groove and said first grease chamber;

Further: said oil groove is higher than said grease chamber;

Further: be provided with the water-cooling tube of loopback in the said grease chamber, stretch out from said bearing upper cover at the two ends of this water-cooling tube;

Further: a wherein end of the said main shaft that stretches out from said bearing (ball) cover is connected with coupling.

Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, owing between bearing inboard and the bearing support the first little grease chamber is arranged, the bearing pellet shot from a slingshot of bearing is immersed in the thin oil in the first little grease chamber, and bearing obtains sufficient lubrication.

2,, so can use liquid thin oil lubricant because grease chamber and the first little grease chamber, the second little grease chamber and oil groove constitute an oil circulating system, during rotation lubricant oil can automatic cycle, cooling and filtration;

3, because bearing (ball) cover form to embed the maze type sealing with " U " shape oil ring that entangles main shaft, can leakage of oil during normal oil level, be the contactless wearing and tearing in gap and embed the maze type sealing;

4, simple and reliable for structure, maintenance is few.

Embodiment

Below in conjunction with the accompanying drawing instance, the utility model is done further to detail:

Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; It comprises the bearing support 12 that has grease chamber 1, is connected bearing upper end cap 5, bearing 17 and bearing 18, main shaft 6 and bearing (ball) cover 7 and 10 that the back forms the Bearing Installation face with bearing support 12; Bearing 17 and 18 is installed in the Bearing Installation face of bearing support 12 and bearing upper end cap 5; The Bearing Installation face is positioned at bearing support 12 and bearing upper end cap 5 two ends, and gapped between bearing inboard and the bearing support, the convex shoulder of this gap and bearing support 12 forms the first little grease chamber 2 and 3; Gapped between bearing 17 outsides and the bearing (ball) cover 7; Form the second little grease chamber 21; Gapped between bearing 18 outsides and the bearing (ball) cover 10, form the second little grease chamber 22, all there is the

oil circuit

23 and 24 that is communicated with grease chamber 1 each lower end, the second little grease chamber; Bearing (ball) cover 7 embeds the maze type sealing with " U " shape oil ring that entangles main shaft 68 compositions, and bearing (ball) cover 10 is formed the sealing of embedding maze type with " U " shape oil ring that entangles main shaft 6 11; The band oil ring 20 that stretches in grease chamber's 1 pasta is housed on the main shaft 6; Be provided with oil groove 25 in the bearing support 12; This oil groove is located at the side of grease chamber 1 and is higher than grease chamber 1, and this side is taken oily side out of for band oil ring 20, and the two ends of oil groove 25 communicate with the first little grease chamber 2 and 3 respectively; Oil groove 25 and little grease chamber 2, be provided with filter screen 26 between 3; Be provided with the water-cooling tube 4 of loopback in the grease chamber 1, stretch out from bearing upper cover 5 at the two ends of this water-cooling tube, and the termination of the main shaft 6 that stretches out from bearing (ball) cover 7 is connected with coupling 15.

When main shaft rotated, band oil ring 20 can be taken lubricant oil in the bearing support grease chamber 1 out of and be thrown in the high oil groove in mating face 25, and the oil content two-way is in filter screen 26 flows to grease chamber 2 small in ends and 3; Lubricated oil vacuole is to the pellet shot from a slingshot of bearing, and oil spill flows out little grease chamber and flows to bearing (ball) cover side grease chamber, and oil flows back in the bearing support grease chamber from the oil return duct that is located at bearing (ball) cover; Bearing (ball) cover is formed the sealing of embedding maze type with " U " shape oil ring, and " U " shape oil ring 8 and 11 is fixed on the main shaft 6, rotates with main shaft; Can oil be thrown away; Avoid the sticking oil leakage of main shaft of outdoor to go out the water-cooling tube of the grease chamber of bearing support, but cutting oil.
