Abstract
The utility model relates to a sealing labyrinth for a high-speed gearbox. The sealing labyrinth comprises a positioning flange (1), an upper labyrinth casing (2), a labyrinth channel I (3), a labyrinth channel II (4), a labyrinth channel III (5), a lower labyrinth casing (6), an oil draining channel (7) and an asbestosed wire gauze (8). The sealing labyrinth is characterized in that the upper labyrinth casing (2) and the lower labyrinth casing (6) are respectively processed and are connected by bolts; an oil sealing disk is arranged at the position, which is positioned on the labyrinth channel I (3), of a high-speed gear shaft to form a first path of oil sealing line; the labyrinth channel II (4) and the labyrinth channel III (5) form second and third paths of oil sealing lines; lubricating oil separated by the labyrinth channel I (3), the labyrinth channel II (4) and the labyrinth channel III (5) reflows into a lubricating oil pool of the high-speed gearbox through the oil draining channel (7); and the asbestosed wire gauze (8) is arranged at an opening of the oil draining channel (7).
Description
Technical field
The utility model relates to the sealing labyrinth, is specifically related to a kind of high-speed gear box with the sealing labyrinth.
Background technique
The high-speed gear box running speed is fast, and each motive position all needs lubricant oil in the casing, and when high-speed gear moved, lubricant oil can be through the contacting point of high speed gear shaft and bearing, and perhaps the contacting point of bearing and bearing shell is toward excessive.The lubricating oil temperature that overflows is high, and environment and casing have been caused destruction, and because overflowing of lubricant oil reduced lubrication effect, has brought no small influence for the operation of high-speed gear box.
Summary of the invention
The purpose of the utility model is to be directed against traditional high-speed gear box shortcoming of sealing lubricating oil well, and a kind of novel and high-speed gear box usefulness sealing that efficient is high labyrinth is provided, and it is installed in the outside of bearing shell.Owing to adopted three labyrinth channels, adopt the high-speed gear box in this sealing labyrinth to have the advantage of good sealing effect, high lubricating effect.
The technological scheme of the utility model is:
A kind of high-speed gear box is with the sealing labyrinth; Comprise locating flange 1, labyrinth upper shell 2, labyrinth channel 1, labyrinth channel 24, labyrinth channel 35, labyrinth lower shell body 6, emptying passage 7, asbestos gauge 8; It is characterized in that labyrinth upper shell 2 and labyrinth lower shell body 6 process respectively, and through the bolt connection; High speed gear shaft is installed the oil sealing disk in the position of labyrinth channel 1, forms the first road oil sealing line; Labyrinth channel 24 constitutes second road and the 3rd road oil sealing line with labyrinth channel 35; The lubricant oil that is intercepted by labyrinth channel 1, labyrinth channel 24, labyrinth channel 35 is back in the lubricating oil bath of high-speed gear box through emptying passage 7; Asbestos gauge 8 is installed in the opening of emptying passage 7.
The utlity model has following advantage:
1) this sealing labyrinth is easy to process.Because the sealing labyrinth is divided into two-part up and down, it is comparatively convenient to process.
2) good sealing effect.Owing to adopted three labyrinth channels, formed the three lines of defence, sealing effect is relatively good.
3) can reclaim leakage of oil.Owing to adopted the emptying passage, the lubricant oil that overflows can reclaim well.
Description of drawings
Fig. 1 is the structural representation of high-speed gear box with the sealing labyrinth
Among the figure, 1. locating flange, 2. labyrinth upper shell, 3. labyrinth channel one, and 4. labyrinth channel two, and 5. labyrinth channel three, 6. labyrinth lower shell body, 7. emptying passage, 8. asbestos gauge.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 1.
A kind of high-speed gear box is with the sealing labyrinth; Comprise locating flange 1, labyrinth upper shell 2, labyrinth channel 1, labyrinth channel 24, labyrinth channel 35, labyrinth lower shell body 6, emptying passage 7, asbestos gauge 8; It is characterized in that labyrinth upper shell 2 and labyrinth lower shell body 6 process respectively, and through the bolt connection; High speed gear shaft is installed the oil sealing disk in the position of labyrinth channel 1, forms the first road oil sealing line; Labyrinth channel 24 constitutes second road and the 3rd road oil sealing line with labyrinth channel 35; The lubricant oil that is intercepted by labyrinth channel 1, labyrinth channel 24, labyrinth channel 35 is back in the lubricating oil bath of high-speed gear box through emptying passage 7; Asbestos gauge 8 is installed in the opening of emptying passage 7.
Working procedure
At first labyrinth upper shell 2 and labyrinth lower shell body 6 are linked to each other oil sealing disk and labyrinth channel one 3 formation oil sealing defence lines, first road on this moment high speed shaft through bolt.If still have lubricant oil to overflow this moment, second road and the 3rd road oil sealing line that then are made up of labyrinth channel 24 and labyrinth channel 35 intercept it.The lubricant oil that is intercepted by labyrinth channel 1, labyrinth channel 24, labyrinth channel 35 is back in the lubricating oil bath of high-speed gear box through emptying passage 7; The opening of emptying passage 7 is installed asbestos gauge 8, can effectively stop the lubricant oil in the casing to get rid of in the emptying passage 7.
