Description
Technical field
This utility model relates to the end seal of a kind of wind-driven generator wheel-box.
Background technology
Wind-power electricity generation, compared with traditional thermal power generation, has the free of contamination advantage of generating, compared with hydroelectric generation, there is capital construction low cost, floor space little, the convenient advantage of maintaining, the most large-scale water-power plant, storage reservoir is also easy to cause downstream certain potential safety hazard.
In wind-driven generator, gear-box is the critical component of wind-driven generator, and the accelerating gearbox for wind power generator that current China uses typically uses non-contacting seal, but oil leakage phenomenon still happens occasionally, and the leakage of oil of solution gear-box has become important problem.
Although the sealing structure of gear-box is improved by someone, but owing to gearbox high-speed level rotating speed is higher, and being placed in open air for a long time, working environment is extremely severe, after often wind turbine gearbox runs a period of time, it may appear that leakage permeability phenomenon in various degree.Therefore, optimize sealing structure wind-driven generator wheel-box is particularly important.
Utility model content
The purpose of this utility model is: extremely severe, after often wind turbine gearbox runs a period of time for wind turbine gearbox working environment, it may appear that the practical problem of leakage permeability phenomenon in various degree, it is provided that a kind of new sealing means.
The purpose of this utility model is achieved in that the end seal of a kind of wind-driven generator wheel-box, including oil scraper ring and disc, it is characterized in that: rotary shaft is supported in casing by sliding bearing, the outside of sliding bearing is provided with oil scraper ring, and oil scraper ring and the rotary shaft joint portion stretching out sliding bearing are provided with the first disc；Transparent cover is tight against oil scraper ring and is bolted on casing, and transparent cover and rotary shaft joint portion are provided with the second disc, transparent cover end face and the second disc joint portion and are provided with V-type dust ring；Transparent cover is provided with the long-pending oil groove corresponding with disc, links up with the spill port running through sliding bearing and casing below long-pending oil groove.
In this utility model: be provided with undergauge step in described rotary shaft, the first disc is tight against the undergauge step in rotary shaft, and the second disc is tight against the first disc.
In this utility model: be provided with annular maze trough, the seam of V-type dust ring and the end contact of end cap on end cap inwall.
The utility model has the advantage of: owing to rotary shaft is supported in casing by sliding bearing, the outside of sliding bearing is provided with oil scraper ring, and oil scraper ring and the rotary shaft joint portion stretching out sliding bearing are provided with the first disc；Transparent cover is tight against oil scraper ring and is bolted on casing, transparent cover and rotary shaft joint portion are provided with the second disc, transparent cover is provided with the long-pending oil groove corresponding with disc, link up with the spill port running through sliding bearing and casing below long-pending oil groove, lubricating oil is through oil scraper ring and the effect of disc, cannot flow to outside end cap, return in casing in time, this considerably reduce Lou permeability phenomenon.Owing to transparent cover end face and the second disc joint portion are provided with the end contact of V-type dust ring, the especially seam of V-type dust ring and end cap, dust can be effectively stoped to enter inside gear-box.Owing to rotary shaft is provided with undergauge step, the first disc is tight against the undergauge step in rotary shaft, and the second disc is tight against the first disc.And end cap inwall is provided with annular maze trough, can act as stoping lubricating oil to flow to outside end cap.This utility model compact conformation.
Accompanying drawing explanation
Fig. 1 be an embodiment of the present utility model structural representation；
In figure, 1, oil scraper ring, the 2, first disc, the 3, second disc, 4, transparent cover, 5, V-type dust ring, 6, casing, 7, sliding bearing, 8, spill port, 9, rotary shaft, 10, long-pending oil groove.
Detailed description of the invention
Accompanying drawing discloses the concrete structure of this utility model embodiment without limitation, is further described this utility model below in conjunction with the accompanying drawings.
As seen from Figure 1, the rotary shaft 9 of wind-driven generator wheel-box end is supported in casing 6 by sliding bearing 7.This utility model includes oil scraper ring 1 and twice disc, and wherein, the outside of sliding bearing 7 is provided with oil scraper ring 1, and oil scraper ring 1 and rotary shaft 9 joint portion stretching out sliding bearing 7 are provided with the first disc 2；Transparent cover 4 is tight against oil scraper ring 2 and is bolted on casing 6, and transparent cover 4 and rotary shaft 9 joint portion are provided with the second disc 3, transparent cover 4 end face and the second disc 3 joint portion and are provided with V-type dust ring 5.Transparent cover 4 is provided with the long-pending oil groove 10 corresponding with disc, links up with the spill port 8 running through sliding bearing 7 and casing 6 below long-pending oil groove 10.
In the present embodiment: described rotary shaft 9 is provided with undergauge step, the first disc 2 is tight against the undergauge step in rotary shaft 9, and the second disc 3 is tight against the first disc 2, the seam of V-type dust ring and the end contact of end cap.
When being embodied as: end cap inwall is provided with annular maze trough.
In work, when rotary shaft 9 high speed rotating, under the effect of oil scraper ring 1, the lubricating oil that is obstructed in a large number returns in gear-box by the spill port 8 of casing 6, the most a small amount of lubricating oil is outbound flowed by the gap of oil scraper ring 1 with the first disc 1, time at the oil thrower flowing to rotary shaft 9, owing to the effect of centrifugal force makes lubricating oil fly out along the radial direction of oil thrower, annular maze trough on end cap enters long-pending oil groove 10 again, spill port 8 oil back chamber below long-pending oil groove 10 return in gear-box.Continue to outbound flow when a small amount of lubricating oil passes through the gap of the first disc 2, the second disc 3, the mode of operation of the second disc 3 first disc 2 will be run into, stop lubricating oil to continue outflow, and they are recovered in gear-box.The V-type dust ring 5 being simultaneously received in the second disc 3 and end cap end face effectively prevents dust from entering inside gear-box.
