[0018] The present invention will now be further explained in conjunction with the drawings. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic manner, so they only show the configuration related to the present invention.
[0019] Such as figure 1 As shown, an assembled mechanical seal structure of a reducer has a crankshaft 1, the crankshaft 1 has a rotating shaft 11, the rotating shaft 11 is inserted into the through cover 2 from the left, the through cover 2 is located at the rightmost end of the rotating shaft 11, the through cover 2 has The first vertical partition, the first inner partition ring 3 is installed on the left side of the transparent cover 2, the first inner partition ring 3 has a second vertical partition, the first vertical partition of the transparent cover 2 and the first inner partition ring The extension direction of the second vertical barrier of 3 is opposite, and the first vertical barrier of the through cover 2 and the second vertical barrier of the first inner ring 3 form a first layer of labyrinth seal.
[0020] The first outer spacer ring 4 is installed on the left side of the first inner spacer ring 3, and the outer stop of the first outer spacer ring 4 is in mating contact with the inner stop of the transparent cover 2.
[0021] The first outer spacer ring 4 has a third vertical barrier, and the first outer spacer ring 4 is sealed with the first inner spacer ring 3 through the third vertical barrier.
[0022] A second inner spacer ring 6 is installed on the left side of the first outer spacer ring 4, and the second inner spacer ring 6 has a fourth vertical spacer. A second outer spacer ring 5 is installed on the left side of the second inner spacer ring 6, and the second outer spacer ring 5 has a fifth vertical spacer. The fourth vertical barrier of the second inner spacer ring 6 and the fifth vertical barrier of the second outer spacer ring 5 form a second layer of labyrinth seal.
[0023] The first inner spacer ring 3 is thermally sleeved into the rotating shaft 11, and the first inner spacer ring 3 is in interference fit with the rotating shaft 11.
[0024] The second inner spacer ring 6 is thermally sleeved into the rotating shaft 11, and the second inner spacer ring 6 is in interference fit with the rotating shaft 11.
[0025] A reducer has the above-mentioned assembled type mechanical seal structure of the reducer, and the left side of the second outer spacer ring 5 is sleeved with bearings and gears.
[0026] First install the transparent cover 2 into the rightmost end of the rotating shaft 11 of the crankshaft 1, and then heat-fit the first inner spacer ring 3. The first inner spacer ring 3 is in interference fit with the rotating shaft 11, and runs with the rotating shaft 11 during operation. , The first vertical barrier of the through cover 2 and the second vertical barrier of the first inner spacer ring 3 form a first layer of labyrinth seal.
[0027] After the first inner spacer ring 3 is installed, the first outer spacer ring 4 is installed so that the outer spigot of the first outer spacer ring 4 and the inner spigot of the transparent cover 2 are connected together.
[0028] After the first outer spacer ring 4 is installed, the second inner spacer ring 6 is heat-fitted, the second inner spacer ring 6 is in interference fit with the rotating shaft 11, and finally the second outer spacer ring 5 is installed. The fourth vertical barrier of the ring 6 and the fifth vertical barrier of the second outer ring 5 form a second layer of labyrinth seal.
[0029] After all the above parts are installed, subsequent parts such as bearings and gears can be installed on the rotating shaft 11 of the crankshaft 1.
[0030] The assembled mechanical seal structure of the reducer of the present invention realizes two-layer effective sealing in a small space.
[0031] The first outer spacer ring 4 and the second outer spacer ring 5 remain stationary with the box of the reducer, and the first inner spacer ring 3 and the second inner spacer ring 6 rotate with the crankshaft 1 to form a labyrinth mechanical seal. The invention saves installation space and can effectively seal.
[0032] Taking the above-mentioned ideal embodiment according to the present invention as enlightenment, through the above-mentioned description content, relevant workers can make various changes and modifications without departing from the scope of the technical idea of the present invention. The technical scope of the present invention is not limited to the content of the description, and its technical scope must be determined according to the scope of the claims.
