Description

Bucket elevator lower part cylinder axle head sealing device

Technical Field

The utility model relates to a bucket elevator technical field especially relates to a bucket elevator lower part cylinder axle head sealing device.

Background

As shown in figure 1, the current method for sealing the shaft end of the lower drum of the bucket elevator mainly comprises the steps of installing an asbestos packing 4 between a sealing seat 1 and a lower drum shaft 3, and after the asbestos packing 1 is worn, tightly pressing the asbestos packing 4 by adjusting bolts on a packing gland 2 to achieve the purpose of sealing. The main disadvantages of the above sealing method are that the asbestos packing 4 is worn quickly, maintained frequently, and easily leaks materials.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome not enough among the prior art, provide a bucket elevator lower part cylinder axle head sealing device.

The utility model discloses a realize through following technical scheme: the utility model provides a bucket elevator lower part cylinder axle head sealing device, include the seal receptacle, can dismantle connect in packing gland on the seal receptacle and set up in mounting hole on seal receptacle, the packing gland, be equipped with packing, oil guide ring and sealing washer in proper order along the axial in the mounting hole, the sealing washer is close to packing gland one side and compresses tightly through packing gland.

Furthermore, the packing has two, two the packing sets up along the mounting hole axial.

Further, the packing is a high water-based packing.

Furthermore, set up first step portion on the terminal surface of packing gland orientation mounting hole, first step portion ladder face is towards oil ring one side of leading, the setting can be dismantled on first step portion to the sealing washer.

Further, the sealing ring is a lip-shaped sealing ring of the rotating shaft.

Furthermore, a second step part is arranged on the end face, facing the sealing seat, of the packing gland, and a third step part clamped with the second step part is arranged on the sealing seat.

The beneficial effects of the utility model reside in that: the high water-based packing, the oil guide ring and the rotary shaft lip-shaped sealing ring are arranged between the sealing seat and the rotary shaft, and the high water-based packing and the rotary shaft are lubricated by lubricating grease stored in the oil guide ring, so that the service life of the high water-based packing is prolonged; meanwhile, three seals are formed by the high water-based packing, the oil guide ring and the rotary shaft lip-shaped sealing ring, so that the sealing reliability is greatly improved.

FIG. 2 is a schematic view of example 1;

fig. 3 is a schematic structural diagram of the packing gland of the present embodiment.

Wherein: 1-a sealing seat, 2-a packing gland, 21-a first step part, 22-a second step part, 3-a drum shaft, 4-a packing, 5-an oil guide ring and 6-a sealing ring.

Detailed Description

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 2 and 3, a bucket elevator lower part roller axle head sealing device, including seal receptacle 1 and packing gland 2, be equipped with the mounting hole coaxial with roller shaft 3 on the seal receptacle 1, be equipped with packing 4, lead oil ring 5 and sealing washer 6 along the axial in the mounting hole in proper order, packing 4, lead oil ring 5 and sealing washer 6 all overlap and establish on roller shaft 3, and packing gland 2 passes through bolt detachable and connects in one side of seal receptacle 1 and compresses tightly sealing washer 6. The packing 4, the oil guide ring 5 and the sealing ring 6 are arranged between the sealing seat 1 and the drum shaft, and the packing 4 and the drum shaft are lubricated by lubricating grease stored in the oil guide ring 5, so that the service life of the packing 4 is prolonged; meanwhile, three seals are formed by the packing 4, the oil guide ring 5 and the sealing ring 6, so that the sealing reliability is greatly improved.

In this embodiment, there are 2 packing 4, and two packing 4 set up along the mounting hole axial, and are high water base packing. In other embodiments, one or more may be provided as desired.

The end face of the packing gland 2 facing the mounting hole is provided with a first step part 21, the first step part 21 faces one side of the oil guide ring 5, the sealing ring 6 is detachably arranged on the first step part 21, and the sealing ring 6 is a rotary shaft lip-shaped sealing ring. The stability of sealing washer 6 can effectively be improved in the cooperation of sealing washer 6 and first step 21, and at the rotation axis rotation in-process, the pivot of effectively laminating when leading the lubricating grease of oil ring 5 and lubricate high water base packing and drum shaft, effectively prevents the excessive of lubricating grease. After the sealing lip is abraded, the sealing lip has certain automatic compensation capacity, and when the sealing lip has relative movement, the friction force caused by the sealing ring is small, and the friction coefficient is stable. Simple structure, convenient use and maintenance and low cost.

For the degree of adaptability that improves packing gland 2 and seal receptacle 1, set up second step portion 22 on packing gland 2 orientation seal receptacle 1's the terminal surface, set up the third step portion with second step portion 22 block on the seal receptacle 1.
