Abstract
An oil scraping seal strip belongs to the fittings for sealing rotating shaft technical field. The utility model is a flexible body formed by an approximately arc oil scraping belt with an opening downward and a square embedded strip integrally connected with the bottom end of the oil scraping belt, wherein the upper end face of the embedded strip is inclined upward to be connected with the inclined, and a plurality of vertical oil leaking holes or oil leaking grooves are arranged close to the outer side on the embedded strip. The utility model can effectively prevent oil leaking from wheel axles.
Description
Technical field
The utility model belongs to the accessory technical field that is used for rotation axis seal, particularly a kind of wiper seal bar.
Background technique
Internal combustion, electric locomotive gear-box are up and down and welded-steel plate construction, and its static and dynamic sealing place adopts the sealing of malthoid bar, though make two seals into from the earliest sealing together, malthoid can only prevent dust and can not effectively prevent leakage of oil.Adopt rubber weather strip at present more existing gear-boxes, but because its structural design is unreasonable, sealing effect is still undesirable.
The model utility content
The utility model purpose is to provide a kind of wiper seal bar that is used in the good seal performance of gear-box lower plate inner seal groove.
For reaching above-mentioned purpose, the utility model by the following technical solutions: wiper seal bar, its serve as reasons flexible body of the square setting-in bar formation that mouthful downward approximate arc frizing band and upper-end surface and frizing band bottom fuse.
Setting-in bar upper-end surface is inclined upwardly and is connected with the frizing band, is provided with some vertical oil leaking holes or leakage of oil groove on the setting-in bar in the outer part.
The utility model can adopt flexible elastic material such as rubber to make, the design of structurally adopting frizing band and setting-in bar to fuse, but embowment during use.In the boxboard inner seal groove, the frizing band is affixed on the gear shaft, and the oil on the wheel shaft is scraped fully under the setting-in bar embedding gear-box.To gear-box lower plate inner seal groove, set oil leaking hole flows in the casing oil that scrapes from wheel shaft from groove again by the vertical oil leaking hole on the setting-in bar or leakage of oil concentrated flow, and flows out from the special use outlet and to collect, thereby effectively prevents leakage of oil, good seal performance.The utility model and outside dust-proofing seal coupling, can effectively prevent into dust and leakage of oil.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment, a kind of wiper seal bar, it is made by rubber material.The approximate rectangular setting-in bar 2 that is fused by the downward approximate arc frizing band 3 of mouth and upper-end surface and frizing band bottom constitutes.Setting-in bar upper-end surface is inclined upwardly and is connected with the frizing band, is provided with vertical leakage of oil groove 1 on the setting-in bar in the outer part.
Claims (2)
1, wiper seal bar, the utility model be characterised in that, its serve as reasons flexible body of the square setting-in bar formation that mouthful downward approximate arc frizing band and upper-end surface and frizing band bottom fuse.
2, wiper seal bar as claimed in claim 1 is characterized in that, setting-in bar upper-end surface is inclined upwardly and is connected with the frizing band, is provided with some vertical oil leaking holes or leakage of oil groove on the setting-in bar in the outer part.
