Problems solved by technology
[0002] Sealing rings are widely used in wind power main gearboxes, which are mainly installed between the input shaft of the gearbox and the expansion sleeve to prevent dust. After forming a closed loop, it is difficult to replace the sealing ring on the tower
[0003] The sealing ring is a rubber wearing part, which is easy to age and cause breakage after running in the wind field for about 3 to 5 years, and loses the dustproof effect, so it needs to be replaced frequently on the wind tower
It is unrealistic to disassemble and assemble parts on the wind tower, and in the process of pasting the seal ring during replacement, it is necessary to hold the seal ring for a long time to keep the pasting surface fixed and ensure that the pasting surface is aligned. The labor intensity of the staff is high and the operation difficulty

Embodiment
[0013] Example: figure 1 , 2 Shown, the present invention is made up of fixed upper and lower platen, screw rod, guide rod, spring, nut etc.
[0014] The said pressing plate is two upper and lower pressing plates respectively. The upper and lower pressing plates are combined or opened by a screw and a nut. After the upper and lower pressing plates are combined, a fixed groove 12 is formed inside, and the shape of the groove is changed according to the shape of the sealing ring. Sure, figure 1 Shown in the figure is the replacement device for the V-shaped sealing ring. Since the material of the sealing ring is rubber and the material of the pressure plate is aluminum, it is avoided to damage the sealing ring during the press-fitting process.
[0015] The screw rods 2, 10 and nuts 1, 11 are used to fix the combination of the upper and lower pressure plates, thereby fixing the bonding surface of the sealing ring.
[0016] The guide rod 5 is used to guide the two lower pressure...

A wind power main gearbox sealing ring replacement device, mainly composed of two left and right upper pressure plates, two left and right lower pressure plates, two left and right screws and nuts, guide rods, and springs, the left upper pressure plate, left lower pressure plate, and right upper pressure plate and the lower right pressure plate are screwed together up and down through their respective two screws and nuts, and the upper and lower joints of the upper left pressure plate and the lower left pressure plate, the upper right pressure plate and the lower right pressure plate are formed with a fixing groove similar in shape to the sealing ring that needs to be replaced There are two guide rods used for guiding in the horizontal connection between the left and right lower pressure plates, and a positioning rod with a spring in the middle is connected horizontally between the left and right lower pressure plates, and one end of the positioning rod is fixed in it. On the lower pressing plate, the other end protrudes from the outside of the other lower pressing plate and is equipped with a rotating nut; it has the characteristics of simple structure, low cost, simple operation, convenient use, and can reduce the labor intensity of the staff.
Description
technical field [0001] The invention relates to a device for replacing the sealing ring of a main gear box of wind power generation equipment, and belongs to the technical field of wind power generation equipment operation and maintenance facilities. Background technique [0002] Sealing rings are widely used in wind power main gearboxes, which are mainly installed between the input shaft of the gearbox and the expansion sleeve to prevent dust. Finally, a closed loop is formed, and it is difficult to replace the sealing ring on the tower. [0003] The sealing ring is a rubber wearing part, which is easy to age and cause breakage after 3 to 5 years of operation in the wind field, and loses the dustproof effect, so it needs to be replaced frequently on the wind tower. It is unrealistic to disassemble and assemble parts on the wind tower, and in the process of pasting the seal ring during replacement, it is necessary to hold the seal ring for a long time to keep the pasting su...
