Abstract
The utility model provides a support structure of an ash ejection mechanism, comprising a rib plate, a shell packing seal assembly, a bearing seat, a bearing, a bearing seal ring and a bearing pressure cover, wherein the rib plate and the bearing seat are welded in one piece to be coupled with the shell of the ash ejection mechanism by a bolt, the axial distance between the bearing seat and the shell packing seal assembly is 150-300mm, the bearing is an concentric endiocentric thrust ball bearing and lubricated by using a lubricating grease, the bearing seal ring is a felt seal ring and arranged on the inner hole of the bearing pressure cover. The beneficial effects of the support structure are that: low failure rate of the bearing assembly, long service life and convenient bearing exchange.
Description
Technical field
The utility model relates to a kind of bearing set of ash exhauster.
Background technology
The axle sleeve of traditional star ash exhauster bearing set is installed in the end cap seal place, because of operating temperature is high, can't lubricate, and axle sleeve and lining friction force are big, and it is very fast to wear and tear.And because the big load of friction force heavily very easily is directed at rotor shaft wearing and tearing and distortion, usually can be stuck in production run.Successively lining was used instead materials such as spheroidal graphite iron and graphite, but all do not obtained effect preferably.Higher because of the grey temperature that following slag system is discharged, in case star-like valve is stuck, maintenance is difficulty very, handles during like the utmost point not, and ash is piled up too highly in the ash bucket, also might cause system shutdown.
Summary of the invention
The purpose of the utility model just provides a kind of bearing set of ash exhauster, improves sealed environment and condition, reduces the bearing fault rate, prolongs the service life of thermoelectric power station ash exhauster.
The technical scheme of the utility model is: a kind of bearing set of ash exhauster; Comprise gusset, housing packing seal assembly, bearing seat, bearing, bearing sealed ring, bearing gland, gusset and bearing seat are welded as a whole and ash discharging gear housing Bolt Connection, with housing packing seal assembly axial distance 150-300 millimeter; Bearing is a radial thrust ball bearing; Adopt grease lubrication, bearing sealed ring is the felt seal ring, is arranged on the endoporus of bearing gland.Housing packing seal assembly uses packing seal, and it is oil tight to reach bearing, and star-like valve does not leak the purpose of ash.
The beneficial effect of the utility model is: the bearing assembly fault rate is low, and operation life is long, and is easy to maintenance.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Can know that with reference to accompanying drawing 1 a kind of bearing set of ash exhauster comprises gusset 1, housing packing seal assembly 2, bearing seat 3, bearing 4, bearing sealed ring 5, bearing gland 6; Gusset 1 is welded as a whole and ash discharging gear housing 7 Bolt Connection with bearing seat 3; With 200 millimeters of housing packing seal assembly 2 axial distances, bearing 4 is a radial thrust ball bearing, adopts grease lubrication; Bearing sealed ring 5 is the felt seal ring, is arranged on the endoporus of bearing gland 6.Housing packing seal assembly 2 uses packing seal, and it is oil tight to reach bearing, and star-like valve does not leak the purpose of ash.
