Abstract
The utility model discloses a hoister tail-gear spindle sealing device which can guarantee the good sealing effect of a sealing box for a long time. The hoister tail-gear spindle sealing device comprises a tail-gear spindle, and a hoister shell, a movable plate, the sealing box and a bearing pedestal are arranged on the tail-gear spindle. A bearing pedestal oil inlet is formed in the bearing pedestal, and the bearing pedestal oil inlet is connected with a grease pump. An oil seal structure is arranged in an inner cavity of the sealing box, and the oil seal structure comprises two framework oil seals arranged side by side. The sealing box is provided with a sealing box oil inlet communicated with inner cavity of the sealing box, and the sealing box oil inlet is connected with the grease pump.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of hoister rear wheel shaft sealer.
Background technique
NE type lift is that employing plate chain is driving component, and hopper is intensive to be arranged on conduction chain continuously, and inflow formula is loaded, the noria of low speed gravity type unloading.
NE type lift is widely applied at cement industry, and chain speed is slow, moves relatively stable.Lift housing, mobile plate, sealing case and bearing support are installed on the tail-gear spindle of this lift, on bearing support, be provided with bearing support filler opening, bearing support filler opening is connected with dry oil pump, and the inner chamber of sealing case is provided with sealing configuration, and sealing configuration is oiliness packing.This lift is in lifting powder process, and particularly the material problem that leaps up between tail-gear spindle and mobile plate can not get effective solution always during finished cement.This can cause hoister rear wheel device buildup, flying dust serious, and environment is severe.Seal failure is first from oiliness packing wear out failure, and ash enters bearing support and damages bearing then, and after bearing damage, tail-gear spindle is because can not locate, and sealing case also can be worn.While therefore changing bearing, also must repair sealing case at every turn.Lift is run-on facility, and ground defect subspaces is little, temperature is high, and environment is poor, changes No. one time bearing time and effort consuming, if tail-gear spindle wearing and tearing must be removed whole tail wheel to repair, has had a strong impact on the continuity of whole production run.
Model utility content
The technical problem that the utility model solves is to provide a kind of hoister rear wheel shaft sealer that guarantees that sealing case long term seal is respond well.
The utility model solves the technological scheme that its technical problem adopts: hoister rear wheel shaft sealer, comprise tail-gear spindle, lift housing, mobile plate, sealing case and bearing support are installed on tail-gear spindle, on bearing support, be provided with bearing support filler opening, bearing support filler opening is connected with dry oil pump, the inner chamber of sealing case is provided with oil seal structure, described oil seal structure comprises two outside framework oil seals that are arranged side by side, on sealing case, be provided with the sealing case filler opening being communicated with the inner chamber of sealing case, sealing case filler opening is connected with described dry oil pump.
Further: between described mobile plate and lift housing, be provided with sealing layer.
Further: described sealing layer is felt layers.
Further: the two ends of described bearing support are connected with mobile plate by link respectively.
The beneficial effects of the utility model are: dry oil pump can pass through the inner chamber make-up oil of sealing case filler opening to sealing case, guarantee that outside framework oil seal is lubricated, can guarantee for a long time that the sealing effect of sealing case is good.Between mobile plate and lift housing, be provided with sealing layer and can guarantee that mobile plate keeps the sealing effect between mobile plate and lift housing when mobile.The two ends of bearing support are connected with mobile plate by link respectively, and bearing support and mobile plate are consistent when mobile, prevent that sealing case from being worn and torn by tail-gear spindle because the relative position of tail-gear spindle and mobile plate changes.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of hoister rear wheel shaft sealer of the present utility model;
In figure, be labeled as: sealing layer 1, lift housing 2, mobile plate 3, sealing case 4, outside framework oil seal 5, sealing case filler opening 6, link 7, bearing support 8, tail-gear spindle 9.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, hoister rear wheel shaft sealer of the present utility model, comprise tail-gear spindle 9, lift housing 2, mobile plate 3, sealing case 4 and bearing support 8 are installed on tail-gear spindle 9, on bearing support 8, be provided with bearing support filler opening, bearing support filler opening is connected with dry oil pump, the inner chamber of sealing case 4 is provided with oil seal structure, described oil seal structure comprises two outside framework oil seals 5 that are arranged side by side, on sealing case, be provided with the sealing case filler opening 6 being communicated with the inner chamber of sealing case, sealing case filler opening 6 is connected with described dry oil pump.Dry oil pump can pass through the inner chamber make-up oil of sealing case filler opening to sealing case, guarantees that outside framework oil seal is lubricated, can guarantee for a long time the sealing effect of sealing case.
On the basis of the above, between described mobile plate 3 and lift housing 2, be provided with sealing layer 1.Described sealing layer 1 can be felt layers etc.Can guarantee that like this mobile plate keeps the sealing effect between mobile plate and lift housing when mobile.
Further, the two ends of described bearing support 8 are connected with mobile plate by link 7 respectively.Can make like this bearing support and mobile plate be consistent when mobile, prevent that sealing case from being worn and torn by tail-gear spindle because the relative position of tail-gear spindle and mobile plate changes.Link 7 can be the structures such as gusset.
