Description
Technical field
The utility model belongs to centrifugal casting machine technical field, seals and fills more particularly to a kind of centrifugal casting machine support roller
Put.
Background technology
Centrifugal casting machine is the key equipment of ball milling cast tube production, in cast tube production process, it is necessary first to which molten iron is entered
Row heating adjustment, the afterwards casting on centrifugal casting machine again.But support roller long period of soaking work in cold water during due to casting
Make, cause that support roller is fragile, service life is short, improve the service life of support roller for extending the time between overhauls(TBO) of centrifugal casting machine extremely
Close important.
The content of the invention
A kind of the shortcomings that the purpose of this utility model is to overcome prior art, there is provided centrifugal casting machine support roller sealing dress
Put, solve that support roller sealing present in the existing centrifugal casting machine course of work is poor, extremely flimsy technical problem.
The utility model is achieved through the following technical solutions：
A kind of centrifugal casting machine riding wheel sealing device, including support roller and supporting-roller shaft, wherein：The support roller center portion is provided with axle
Hole, axis hole both ends are respectively arranged with bearing, and for supporting-roller shaft through in two side bearings, axis hole both ends are respectively arranged with bearing gland,
Sealing axle sleeve is provided between bearing gland and supporting-roller shaft, sealing axle sleeve is interference fit, sealing axle sleeve and support roller with supporting-roller shaft
Sealing ring is provided between axle mating surface；Two rotary shafts of opening direction identical are provided between bearing gland and sealing axle sleeve
Lip packing.
Further, the sealing axle sleeve surface is provided with chromium coating.
The setting of two rotating shaft lip-shaped sealings and sealing ring in the utility model, and between sealing axle sleeve and supporting-roller shaft
Interference fit, improve the sealing of support roller；Sealing axle sleeve is separately provided, and is facilitated it to carry out chrome-faced processing, is avoided
Support roller sealing is poor, the defects of easily damaging.
Compared with prior art, the utility model have good seal performance, service life are long, cost is low, it is easy promote etc. it is excellent
Point.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of centrifugal casting machine riding wheel sealing device, including support roller 1 and supporting-roller shaft 4, wherein：The support roller
1 center portion is provided with axis hole, and axis hole both ends are respectively arranged with bearing 5, and the axle of support roller 1 is through in two side bearings 5, axis hole both ends difference
Bearing gland 2 is provided with, sealing axle sleeve 3 is provided between bearing gland 2 and supporting-roller shaft 4, sealing axle sleeve 3 was with supporting-roller shaft 4
It is full of cooperation, sealing ring 6 is provided between sealing axle sleeve 3 and the mating surface of supporting-roller shaft 4；Set between bearing gland 2 and sealing axle sleeve 3
There are two rotating shaft lip-shaped sealings 7 of opening direction identical.
Further, the surface of sealing axle sleeve 3 is provided with chromium coating.
The essence that the utility model can be embodied without departing from invention in a variety of forms, it should therefore be appreciated that above-mentioned
Embodiment is not limited to foregoing details, and should widely be explained in claim limited range, therefore falls into right and want
Ask or the change in its equivalent scope and remodeling all should be claim and covered.
