Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to an aluminum-magnesium alloy flange for a transmission shaft which is easy to maintain. Background Art

[0002] ‌Flange is a part used to connect pipes, valves and other equipment, usually made of carbon steel, low alloy steel, stainless steel and other materials. ‌Flange connects two planes tightly with bolts and gaskets to ensure a leak-proof seal. It is widely used in construction, light and heavy industries, plumbing, electricity and other fields, especially in the connection of pipes and equipment in the fields of chemical, petroleum, pharmaceutical, food and other fields, the role of flange is particularly important.

[0003] ‌Aluminum-magnesium alloy flanges have a lower density and are much lighter than traditional materials such as carbon steel and stainless steel. Therefore, they can reduce the weight of the entire equipment and reduce transportation and installation costs. At the same time, they have strong corrosion resistance, thereby increasing the service life of the flange.

[0004] For example, a transmission shaft flange with application number 202022342706.X, by designing the two symmetrical sides of the rectangular flange into arcs, makes it easier to fill the four corners during forging and filling, reduces the scrap rate of the finished product, and reduces the flange thickness by means of a reinforcement part. On the one hand, the flange connection strength is ensured by the reinforcement part, and on the other hand, the material cost is effectively saved. However, the device still has certain defects;

[0005] During long-term use, it is difficult to maintain the flange, which makes the surface of the flange easy to rust, and at the same time, the surface of the drive shaft is corroded, thereby reducing the service life of the drive shaft and the flange.

[0006] Therefore, we propose an aluminum-magnesium alloy flange for a transmission shaft that is easy to maintain in order to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of the utility model is to provide an aluminum-magnesium alloy flange for a transmission shaft that is easy to maintain, so as to solve the problem raised by the above-mentioned background technology that the flanges on the current market are not easy to maintain during long-term use, so that the surface of the flange is easily corroded, and the surface of the transmission shaft is also corroded, thereby reducing the service life of the transmission shaft and the flange.

[0008] To achieve the above object, the utility model provides the following technical solution: an aluminum-magnesium alloy flange for a transmission shaft that is easy to maintain, comprising a rectangular flange and an oil storage tank, a connecting mechanism is installed above the rectangular flange, and a transmission shaft mounting hole is opened on the connecting mechanism, and a sponge component is arranged on the left side of the rectangular flange;

[0009] An oil storage ring is installed on the outer side of the connecting mechanism, and an oil storage groove is opened inside the oil storage ring, an oil outlet hole is opened on the lower surface of the oil storage ring, a limit block is installed inside the oil storage groove, and a sealing ring is arranged inside the oil storage groove, and an adjustment hole is opened on the sealing ring;

[0010] An oil filling groove is provided on the upper surface of the oil storage ring, and a sealing cover is provided on the oil filling groove.

[0011] Preferably, the sponge assembly includes a sponge body, a connecting block, a rubber block and an abutment block. A built-in groove is opened on the left side of the rectangular flange, and the sponge assembly is snap-connected with the built-in groove. A connecting block is installed on the left side of the sponge body, and rubber blocks are installed on the front and rear sides of the connecting block. An abutment block is installed on the left side of the connecting block.

[0012] With the above structural design, the sponge component is pulled out, the anti-rust oil on the upper surface of the rectangular flange is absorbed by the sponge body, and then the anti-rust oil is applied to the aluminum-magnesium alloy flange and the drive shaft through the sponge body, thereby facilitating the maintenance of the aluminum-magnesium alloy flange.

[0013] Preferably, both left and right sides of the rubber block are designed in an arc-shaped structure, and the sponge body is located inside the built-in groove on the rectangular flange.

[0014] With the above structural design, after the maintenance of the aluminum-magnesium alloy flange is completed, the sponge component is inserted into the built-in groove on the rectangular flange, so that the rubber block on the connecting block abuts against the built-in groove, so that the sponge component is not easy to fall off and is easy to extract.

[0015] Preferably, the sealing ring is located between the limiting block and the inner bottom surface of the oil storage ring, the oil outlet holes are equidistantly arranged on the oil storage ring, and the adjustment holes are equidistantly arranged on the sealing ring.

[0016] With the above structural design, the limit block limits the sealing ring, so that the sealing ring will not be separated from the inner bottom surface of the oil storage ring when the sealing ring rotates, thereby improving the sealing performance of the sealing ring to the inner bottom of the oil storage ring. Since the sealing ring and the inner bottom of the oil storage ring are not completely sealed, the anti-rust oil can slowly overflow from the gap between the sealing ring and the inner bottom of the oil storage ring to protect the connecting mechanism. The sealing ring can also be rotated to make the adjustment hole on the sealing ring and the oil outlet hole on the oil storage ring, and the anti-rust oil can be discharged relatively quickly through the adjustment hole and the oil outlet hole, and then the anti-rust oil is absorbed by the sponge.

[0017] Preferably, an adjustment handle is vertically mounted on the sealing ring, and anti-slip grooves are provided on the adjustment handle.

[0018] With the above structural design, the sealing ring can be driven to rotate by adjusting the handle. If necessary, a tool can be used to push the adjusting handle to complete the rotation of the sealing ring.

[0019] Preferably, the diameter of the adjustment handle is smaller than the width of the oil filling groove, and the oil filling groove is designed to be an arc-shaped structure.

[0020] With the above structural design, anti-rust oil is injected into the oil storage ring through the oil filling groove, and the oil storage ring stores the anti-rust oil.

[0021] Preferably, the length of the adjustment handle is smaller than the height of the oil storage tank, and the sealing cover can be a rubber arc block.

[0022] With the above structural design, after the oil filling through the oil filling groove is completed, the sealing cover is inserted into the oil filling groove to achieve sealing of the oil filling groove.

[0025] 2. An oil storage ring and a sealing ring are provided. Since the sealing ring and the inner bottom of the oil storage ring are not completely sealed, the anti-rust oil can slowly overflow from the gap between the sealing ring and the inner bottom of the oil storage ring to protect the connecting mechanism.
