Abstract

The invention discloses a combined sealing device of a grinding roller shaft. The combined sealing device comprises a grinding roller body and a grinding roller main shaft, wherein the grinding roller main shaft is fixed on the grinding roller body; a grinding roller transmission casing sleeves the grinding roller main shaft; a grinding roller transmission shaft sealing end cover is arranged between the grinding roller transmission casing and the grinding roller body; the grinding roller body and the grinding roller transmission shaft sealing end cover are sealed through a maze sealing structure; O-shaped seal rings are arranged between the grinding roller transmission casing and the grinding roller transmission shaft sealing end cover; and the grinding roller main shaft and the grinding roller transmission shaft sealing end cover are sealed through axial double oil seal sealing structures. According to the combined sealing device, the O-shaped seal rings are adopted for sealing to prevent the lubricating oil from leaking from the transmission shaft and the casing, the lubricating oil is prevented from leaking from the grinding roller shaft in the radial direction through double oil seal, and the dust particles are prevented from abrading and polluting the grinding roller shaft through the planar maze structure, so that the sealing effect is improved in a doubled manner, the stability of a device is obviously improved, and the service life of the device is obviously prolonged.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a combined sealing device for a grinding roller shaft.
