Abstract
The utility model discloses a composite seal device of grinding roller axle, including grinding roller body and grinding roller main shaft, on the grinding roller main shaft was fixed in grinding roller body, grinding roller main shaft overcoat had grinding roller transmission housing, is equipped with grinding roller transmission shaft end cover between grinding roller transmission housing and the grinding roller body, it is sealed through labyrinth seal structure between grinding roller body and the grinding roller transmission shaft end cover, be equipped with O type sealing washer between grinding roller transmission housing and the grinding roller transmission shaft end cover, it is sealed through axial double oil seal seal structure between grinding roller main shaft and the grinding roller transmission shaft end cover. The utility model discloses an oozing of the sealed transmission shaft casing lubricating oil of O type sealing washer, guarantee the seepage of the grinding roller diameter of axle to oil through the double oil seal, prevent through plane labyrinth structure that dust particle from having had improvement at double to the wearing and tearing and the pollution of grinding roller axle, sealed effect, makes the stability and the life -span of equipment have obvious improvement.
Description
Technical field
This utility model belongs to mechanical field, is specifically related to the combination sealing arrangement of a kind of shaft of grinding roller.
Background technology
Flour mill is widely used in the attrition process of building materials, metallurgy, chemical industry, mine, material etc..The tradition grinding roller main shaft of mill, there is gap between grinding roller transmission shell and grinding roller body three, lubricating oil can ooze out, and when material is ground to certain fineness after, has probability trickle down from gap or be directly clamped among wherein.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, the combination sealing arrangement of a kind of shaft of grinding roller.
Technical scheme: in order to reach foregoing invention purpose, this utility model is specifically performed by: the combination sealing arrangement of a kind of shaft of grinding roller, including grinding roller body and grinding roller main shaft, grinding roller main shaft is fixed on grinding roller body, grinding roller spindle jacket has grinding roller transmission shell, grinding roller drive shaft seal end cap it is provided with between grinding roller transmission shell and grinding roller body, sealed by labyrinth seal structure between described grinding roller body and grinding roller drive shaft seal end cap, it is provided with O RunddichtringO between grinding roller transmission shell and grinding roller drive shaft seal end cap, sealing structure is sealed by axial double oil seal between grinding roller main shaft and grinding roller drive shaft seal end cap.
Beneficial effect: this utility model is compared with conventional art, by oozing out of O RunddichtringO seal transmission shaft housing lubricating oil；The seepage of shaft of grinding roller radially oil is ensured by double oil seal；Preventing dust granules to the abrasion of shaft of grinding roller and pollution by plane labyrinth structure, sealing effectiveness has had and has increased exponentially, and makes the stability of equipment and life-span be significantly improved.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
