Description

Horizontal pump self-sealing bearing gland and horizontal pump self-sealing bearing

Technical Field

The utility model relates to a horizontal pump bearing box technical field provides a horizontal pump self sealss bearing gland and horizontal pump self sealss bearing very much.

Background

When the horizontal thin oil self-lubricating centrifugal pump rotates at a high speed, part of lubricating oil brought out by the rolling bearing and the oil lifting ring can splash to the inner wall of the bearing gland, but because the oil containing groove and the shaft are gapped, part of the oil can leak from the rear end of the bearing gland, so that the oil in the bearing box is gradually reduced, the safe operation of equipment is directly influenced, and the waste of the lubricating oil is caused. Meanwhile, external dust and water can enter an oil pool in the box body through the gap, so that lubricating oil emulsification is caused, and equipment operation is influenced.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a horizontal pump self sealss bearing gland and horizontal pump self sealss bearing.

The utility model discloses a realize like this, a horizontal pump self sealss bearing gland is equipped with the hole that is used for the axle to pass on bearing gland's the lid, is equipped with spiral oilgroove on the pore wall, and the direction of rotation of oilgroove is outside-in screw in, and the oilgroove keeps away from the inside one end of bearing box promptly for closed form, and the oilgroove is close to the inside one end of bearing box and the inside switch-on of bearing box.

Furthermore, two sides of the section of the oil containing groove are straight edges, and the lower side of the section is an arc line segment.

Further, the direction of rotation that contains the oil groove can be levogyration or dextrorotation according to the pump shaft pivoted direction, and when inwards looking from the bearing gland outside, the direction of rotation that contains the oil groove is the levogyration, and when the pump shaft clockwise rotation, the direction of rotation that contains the oil groove is the dextrorotation.

Further, the integral oil-containing groove has an acute included angle of 85-95 degrees with the horizontal direction.

Furthermore, a vertical annular dirt-containing groove is formed in the inner wall of the upper hole of the bearing gland cover body on the outer side of the oil-containing groove.

Furthermore, a sewage draining outlet is arranged at the lower side of the sewage containing groove.

The utility model also provides an adopt above-mentioned bearing gland's horizontal pump self sealss bearing.

Compared with the prior art, the utility model has the advantages of:

1. when the pump rotates, the oil between the bearing gland and the pump shaft can rotate and is discharged back to an oil pool of the bearing box body after being pressurized according to the rotation direction of the oil containing groove, so that the self-sealing effect is realized, and the lubricating oil in the bearing box body is prevented from leaking to the outside;

2. when sewage enters the gap between the pump shaft and the gland through the dustproof disc, the sewage containing groove can be arranged outside the box body through the sewage discharge hole, and the dustproof and waterproof effects are better.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and embodiments:

FIG. 1 is a schematic view of a conventional bearing gland application;

FIG. 2 is a schematic view of the conventional bearing cover structure shown in FIG. 1;

fig. 3 is a schematic view of the bearing gland structure protected by the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, which are schematic diagrams of a conventional bearing gland and an application thereof, when a pump rotates at a high speed, part of lubricating oil carried by a rolling bearing 7 and an oil lifting ring 6 splashes to the inner wall of the bearing gland 1, but since an oil containing groove has a gap with a shaft, part of the oil leaks from the rear end of the bearing gland 1, so that the oil in a bearing box is gradually reduced, which directly affects the safe operation of equipment and causes the waste of the lubricating oil. Meanwhile, after entering the dustproof cover 5, external dust and water can also enter an oil pool in the box body through the gap.

In order to solve the technical problem, the utility model provides a horizontal pump self sealss bearing gland refers to fig. 3, is equipped with the hole that is used for the axle to pass on bearing gland 1's the lid, is equipped with spiral oiliness groove 2 on the pore wall, and the direction of rotation of oiliness groove 2 is outside-in screw in, and the inside one end of bearing box is kept away from to oiliness groove 2 for closed form, and oiliness groove 2 is close to the inside one end of bearing box and the inside switch-on of the pump body.

When using this bearing gland 1, when the pump is rotatory, make the oil between bearing gland 1 and the pump shaft, can be according to containing oil groove 2 revolve to rotatory, pressure boost back row return to the oil bath of bearing box, just so realized the effect of self sealss, avoided the lubricating oil of the inside to leak the outside.

In order to enable the oil in the oil containing groove 2 to move according to the constrained track, as an improvement of the technical scheme, two sides of the section of the oil containing groove 2 are straight edges, and the lower side of the section is an arc line segment.

Specifically, the direction of rotation of oil groove 2 can be left-handed or right-handed according to the direction of pump shaft rotation, and when looking inwards from the bearing gland outside, the direction of rotation of oil groove 2 is left-handed when the pump shaft anticlockwise rotates, and the direction of rotation of oil groove 2 is right-handed when the pump shaft clockwise rotates.

Preferably, the oil-containing groove 2 has an acute angle of 85-95 ° with the horizontal direction.

In order to further prevent water and dust, as an improvement of the technical scheme, a vertical annular dirt-containing groove 3 is arranged on the inner wall of the upper hole of the bearing gland 1 cover body outside the oil-containing groove 2.

When sewage enters a gap between the pump shaft and the bearing gland 1 through the dustproof disc 5, the sewage can enter the sewage containing groove 3 and cannot enter the pump body.

In order to discharge dust or water in time, as an improvement of the technical scheme, a sewage discharge port 4 is arranged at the lower side of the sewage containing groove 3.

As an application, will the utility model provides a bearing gland uses on horizontal pump self sealss bearing, plays self sealss and antifouling effect to the bearing.
