Description
Technical field
The utility model relates to a kind of sealing arrangement, particularly relates to a kind of hoister rear wheel shaft sealer.
Background technology
Gig be a kind of with plate chain for driving component, hopper is intensive to be arranged on conduction chain continuously.Mainly be applicable to the continuous and perpendicular lifting of powdery, graininess and piece material, be widely used in the industries such as cement.Hoister rear wheel is the vitals of gig, and play and change the direction of chain, the tensioning of adjusting chain, tail wheel is arranged on tail-gear spindle.At present, hoister rear wheel axle is provided with gig housing, portable plate, oil sealing, oil seal seat, bearing, Bearing outer is provided with bearing seat, and they are enclosed within tail-gear spindle successively.Gig all can with certain impact when starting moment and each tooth mesh, drive the upper and lower play of tail-gear spindle, thus drive portable plate, oil sealing, oil seal seat, the upper and lower play of bearing seat, because the frequency of bearing seat, oil seal seat, the upper and lower play of sliding seat is inconsistent, cause oil sealing serious wear, reduce the service life of oil sealing.When gig is at lifting powder, particularly finished cement, causes hoister rear wheel device to alter material, flying dust is serious, and environmental facies are when severe, and bearing also often damages because entering ash, easily axle is worn and torn after bearing damage.Gig is run-on facility, and ground defect subspaces is little, temperature is high, and environment is poor, changes a bearing time and effort consuming, often due to axle wearing and tearing, whole tail wheel must be split out reparation, have a strong impact on the continuity of whole production run.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hoister rear wheel shaft sealer improving sealing period of service.
The utility model solves the technical scheme that its technical matters adopts: hoister rear wheel shaft sealer, comprise tail-gear spindle, gig housing, portable plate, oil sealing, oil seal seat, bearing, gig housing, portable plate, oil sealing, oil seal seat, bearing are enclosed within tail-gear spindle successively, the connection of bearing coupling arranges bearing seat, oil seal seat is connected with portable plate, oil sealing is positioned at the inner chamber of oil seal seat, and oil seal seat is arranged on the inner chamber of bearing seat, and the outside face of oil seal seat is close to the inside face leaning against bearing seat.
Further, gig housing and portable plate are provided with sealing.
Further, felt seal is sealed into.
Further, also comprise pressing plate, pressing plate is arranged on after bearing seat and is enclosed within tail-gear spindle, and pressing plate two ends are connected with portable plate by attaching parts.
Further, attaching parts is bolt.
Further, oil sealing is two outside framework oil seals be arranged side by side.
The beneficial effects of the utility model are: oil seal seat is arranged on the inner chamber of bearing seat, and the outside face of oil seal seat is close to the inside face leaning against bearing seat, oil seal seat and bearing seat are fitted tightly be integrated, that is to say that portable plate, oil sealing, oil seal seat, bearing seat are connected as a single entity, they are the same with the floating of the upper and lower play of tail-gear spindle, time, frequency, the relative movement that elimination oil sealing produces with miscellaneous part with tail-gear spindle play is to the damage of oil sealing, improve the period of service of oil sealing, thus also improve the service life of bearing and the continuity of production, reduce the cost of overhaul.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Mark in figure: tail-gear spindle 1, gig housing 2, portable plate 3, oil sealing 4, oil seal seat 5, bearing 6, bearing seat 7, pressing plate 8, attaching parts 9, sealing 10.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of hoister rear wheel shaft sealer of the utility model, comprise tail-gear spindle 1, gig housing 2, portable plate 3, oil sealing 4, oil seal seat 5, bearing 6, gig housing 2, portable plate 3, oil sealing 4, oil seal seat 5, bearing 6 are enclosed within tail-gear spindle 1 successively, oil sealing 4 is two outside framework oil seals be arranged side by side, bearing 6 mates connection and arranges bearing seat 7, oil seal seat 5 is connected with portable plate 3, oil sealing 4 is positioned at the inner chamber of oil seal seat 5, oil seal seat 5 is arranged on the inner chamber of bearing seat 7, and the outside face of oil seal seat 5 is close to the inside face leaning against bearing seat 7.Oil seal seat 5 and bearing seat 7 are fitted tightly be integrated, that is to say that portable plate 3, oil sealing 4, oil seal seat 5,7, bearing are connected as a single entity, they are the same with the floating of tail-gear spindle about 1 play, time, frequency, the relative movement that elimination oil sealing 4 produces with miscellaneous part with the play of tail-gear spindle 1 is to the damage of oil sealing 4, improve the period of service of oil sealing 4, thus also improve the service life of bearing 6 and the continuity of production, reduce the cost of overhaul.
Concrete, gig housing 2 and portable plate 3 are provided with sealing 10.Sealing 10 can be felt, filler etc., arranges like this and ensures that portable plate 3 keeps the sealing effectiveness between gig housing 2 and portable plate 3 when the play with tail-gear spindle 1.Further, also arrange pressing plate 8, pressing plate 8 is arranged on bearing seat 7 and is enclosed within tail-gear spindle 1 below, and pressing plate 8 two ends are connected with portable plate 3 by attaching parts 9.Pressing plate 8 makes portable plate 3 compress, and ensure the effect of sealing 10, attaching parts 9 can use bolt, according to actual conditions, by adjusting bolt, regulate the degree of tension of sealing 10, also the degree of tension between adjustable plate 3 and bearing seat 7 is that sealing arrangement reaches optimal seal effect.
