Abstract

The utility model relates to a buckle cladding formula beam-pumping unit reducing gear box output shaft broken ring rubber seal. The main problem that the work load is increased because parts such as a crank, a bush and a connecting rod need to be disassembled when the sealing ring of the output shaft of the reduction gearbox of the existing pumping unit is replaced is solved. The method is characterized in that: the main part (1) both ends are concave end (2) and convex end (3) respectively, convex end (3) are connected with concave end (2), main part (1) inside is inlayed and is had steel strapping (4). The broken ring rubber seal ring of the output shaft of the buckle coated type reduction gearbox of the pumping unit does not need to disassemble a crank, a bush, a connecting rod and the like during installation and replacement, and does not need the cooperation of a crane and a truck, so that the workload is greatly reduced.

Description

Buckle cladding type oil pumping machine reduction box output shaft broken ring rubber seal ring

Technical Field

The utility model relates to the field of machinary, a buckle cladding formula beam-pumping unit reducing gear box output shaft broken ring rubber seal specifically says so.

Background

Because the sealing ring of the output shaft of the reduction gearbox of the pumping unit on the oil field at present is annular, and the output shaft of the reduction gearbox is provided with the crank, the crank pin, the bush, the connecting rod and the balance block, the crank pin, the bush, the connecting rod and the balance block need to be disassembled when the sealing ring is replaced, and the matching of a crane and a truck is needed, so that the workload is large, the number of personnel is large, the cost is.

SUMMERY OF THE UTILITY MODEL

In order to overcome spare parts such as current beam-pumping unit reducing gear box output shaft sealing washer need dismantle crank and bush, connecting rod when changing and make the not enough of increase work load, the utility model provides a buckle cladding formula beam-pumping unit reducing gear box output shaft broken ring rubber seal, this buckle cladding formula beam-pumping unit reducing gear box output shaft broken ring rubber seal need not dismantle crank and bush, connecting rod etc. when the installation is changed, do not need crane truck cooperation, the work load that has significantly reduced.

The technical scheme of the utility model is that: the utility model provides a buckle cladding formula beam-pumping unit reducing gear box output shaft broken ring rubber seal, includes annular main part, the main part both ends are concave end and protruding end respectively, protruding end and concave end are connected, the inside steel strapping that inlays of main part.

The inner part of the concave end is provided with a groove, the convex end is arranged in the groove, connecting columns are arranged on two sides of the rear part of the convex end, and the front part of the concave end is provided with connecting holes matched with the connecting columns.

The steel strapping tape is characterized in that a strapping tape connector is fixed on the fixed end of the steel strapping tape, the front end of the strapping tape connector is arc-shaped, a steel ball is arranged in the steel strapping tape connector, and the free end of the steel strapping tape is clamped on the strapping tape connector through the steel ball.

The fixed end of the steel strapping tape is positioned in the convex end, and the free end of the steel strapping tape is positioned in the concave end.

The utility model discloses following beneficial effect has: by adopting the scheme, the sealing ring is a broken ring, is connected with the concave end through the convex end, and is prevented from being buckled by the steel strapping tape, so that when the sealing ring is replaced, a crank pin, a bush, a connecting rod and a balance block do not need to be disassembled, and the cooperation of a crane and a truck is not needed, thereby greatly reducing the workload. And the convex-concave end naturally forms a lubricating oil flow channel when the sealing ring is used, so that lubricating oil hardly passes through the sealing ring, and the sealing effect is enhanced.

Drawings

Fig. 1 is a perspective view of the present invention;

fig. 2 is a cross-sectional view of the present invention;

fig. 3 is a schematic view at the strap connector.

In the figure, 1-a main body, 2-a concave end, 3-a convex end, 4-a steel strapping tape, 5-a connecting hole, 6-a connecting column, 7-a strapping tape connector, 8-a steel ball, 4-a free end and 4-a fixed end.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in figures 1 to 3, the broken ring rubber seal ring for the output shaft of the reduction gearbox of the snap-in coated pumping unit comprises an annular main body 1, wherein a concave end 2 and a convex end 3 are respectively arranged at two ends of the main body 1, a square groove is formed in the concave end 2, and the front end of the convex end 3 is arranged in the groove. The two sides of the rear part of the convex end 3 are provided with connecting columns 6, the front part of the concave end 2 is provided with a connecting hole 5, and when the convex end 3 is connected with the concave end 2, the connecting columns 6 are clamped in the connecting holes 5, so that the main body 1 forms a circular ring. The steel strapping tape 4 is embedded in the main body 1, the steel strapping tape 4 is divided into a fixed end 4-2 and a free end 4-1, wherein the fixed end 4-2 is positioned in the convex end 3, and the free end 4-1 is positioned in the concave end 2. The steel strapping tape is characterized in that a strapping tape connector 7 is fixed on the fixed end 4-2, the strapping tape connector 7 is sleeved outside the fixed end 4-2 of the steel strapping tape 4, the front end of the strapping tape connector 7 is arc-shaped, a steel ball 8 is arranged inside the strapping tape connector, and the free end 4-1 of the steel strapping tape 4 is clamped on the strapping tape connector 7 through the steel ball 8. Because the front end of the binding belt connector 7 is arc-shaped, when the steel ball 8 moves backwards, the steel ball 8 is clamped on the arc-shaped surface, so that the steel ball 8 can only move backwards, and the free end 4-1 can only move forwards and can not move backwards, thereby realizing the function of preventing the back-off. After the convex end 3 and the concave end 2 of the sealing ring are connected, a lubricating oil flow channel is naturally formed at the contact part, and then the sealing ring is sealed by sealing glue, so that lubricating oil hardly passes through the sealing ring, the effect of sealing an interface is achieved, and the sealing effect is enhanced.

The sealing ring is used on an output shaft of a reduction box of an oil pumping unit, when the sealing ring needs to be replaced, only the old sealing ring needs to be taken down, two ends of the broken ring rubber sealing ring are slightly broken and sleeved on the output shaft of the reduction box, then the concave end 2 and the convex end 3 are connected, the connecting column 6 is clamped in the connecting hole 5, the free end 4-1 and the fixed end 4-2 of the steel strapping tape 4 are connected together, and the sealing ring can be prevented from being separated due to the stopping function of the steel strapping tape 4. When the sealing ring is replaced, the crank pin, the bush, the connecting rod and the balance block do not need to be disassembled, so that the cooperation of a crane and a truck is not needed, and the workload is greatly reduced.
