Abstract

The utility model discloses a waterproof and dustproof roller wheel device for an escalator, comprising a rolling wheel and a wheel axle, wherein the wheel axle penetrates through the axis of the rolling wheel; a seal inner ring is arranged on the wheel axle, and a seal outer ring is arranged on the rolling wheel; one of the seal inner ring and the seal outer ring is provided with a seal lip made of elastic materials, and the other one of the seal inner ring and the seal outer ring is contacted and matched with the seal lip. In the utility model, clearance does not exist between the parts relatively moving, therefore, the sealing effect is better, the maintenance cost of the escalator is reduced, and the service life of the rolling wheel and the wheel axle of the escalator can be prolonged.

Description

Escalator water proof and dust proof roller devices
Technical field
The utility model relates to a kind of escalator water proof and dust proof roller devices.
Background technology
In escalator, roller is installed on the wheel shaft, because roller need rotate with respect to wheel shaft, just in actual use, extraneous water and dust very easily enter into roller and wheel shaft matching part, have influence on cooperating between roller and the wheel shaft, when this escalator during in outdoor application, environment moist and many dirt can cause more escalator and seriously influence, make roller, wheel shaft be easy to occur corrosion, rotate phenomenons such as not smooth and damage, thereby make roller, the wheel shaft lost of life, the maintenance cost of escalator increases.
For avoiding this defective, the waterproof and dustproof structure that present most of escalator adopts is to be provided with the labyrinth type waterproof and dustproof structure at roller and wheel shaft cooperation place, this structure is the non-contacting seal structure, between the parts of relative motion, there is the gap, but under the outdoor environment of, humid environment more at dust, its water proof and dust proof effect is not satisfactory.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, a kind of escalator water proof and dust proof roller devices is provided, water proof and dust proof effect of the present utility model is even more ideal, has reduced the maintenance cost of escalator, prolongs the service life of escalator roller and wheel shaft.
Its technical scheme is as follows:
A kind of escalator water proof and dust proof roller devices comprises roller, wheel shaft, and wheel shaft passes the axle center of roller; The sealing inner ring is housed on wheel shaft, sealed outer ring is housed on roller, on sealing inner ring, sealed outer ring both one of them, be provided with the sealing lip of making by elastomeric material, both two touching with the sealing lipped joint and to cooperate wherein of sealing inner ring, sealed outer ring.
In the aforementioned schemes, sealing lip can be located on the sealing inner ring, and sealed outer ring and sealing lip seal contact matching, also sealing lip can be located on the sealed outer ring, and sealing inner ring and sealing lip seal contact matching.
The utility model is because sealing lip makes two parts contacts of mutual motion under the elastic force effect, there is not the gap between the parts of two relative motions, can avoid extraneous dust and water to enter into the position that roller cooperates with wheel shaft by actv., the sealing effectiveness ideal, reduced the maintenance cost of escalator, improve the service life of escalator roller and wheel shaft, the utility model is particularly useful for the outdoor use escalator.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
Be provided with spacing sleeve on described wheel shaft, described sealing inner ring is located on this spacing sleeve.Be provided with after the spacing sleeve, can other parts that be installed on the wheel shaft be positioned.
Described sealed outer ring comprises the outer ring body of being made by metallic material, and described sealing lip is located on this outer ring body.
Described sealing lip comprises first sealing lip and second sealing lip at least, and first sealing lip is close to the outside face of described sealing inner ring, and second sealing lip is close to the side of described sealing inner ring; First sealing lip, second sealing lip and described sealing inner ring surround first annular seal space.Further, described sealing lip also includes the 3rd sealing lip, and the 3rd sealing lip is close to the inside face of described sealing inner ring, and the 3rd sealing lip, second sealing lip and described sealing inner ring surround second annular seal space.Can play multi-layer sealed buffer action by multi-layer sealed lip, sealing effectiveness is even more ideal.
Described sealing inner ring and wheel shaft interference fit, described sealed outer ring and roller interference fit.
In sum, the utility model has the advantages that: do not have the gap between the parts of relative motion, sealing effectiveness is better, has reduced the maintenance cost of escalator, prolongs the service life of escalator roller and wheel shaft.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
Embodiment one
As shown in Figure 1 and Figure 2, a kind of escalator water proof and dust proof roller devices comprises roller 1, wheel shaft 2, and wheel shaft 2 passes the axle center of roller 1, and is provided with bearing 12 between roller 1 and wheel shaft 2; Sealing inner ring 3 is housed on wheel shaft 2, sealed outer ring 4 is housed on roller 1, on sealing inner ring 3, sealed outer ring 4 both one of them, be provided with the sealing lip of making by elastomeric material, both two touching with the sealing lipped joint and to cooperate wherein of sealing inner ring 3, sealed outer ring 4.
In the present embodiment, described sealed outer ring 4 comprises the outer ring body of being made by metallic material 9, and described sealing lip is located on this outer ring body 9.Described sealing lip comprises that first sealing lip 5, second sealing lip 6 and the 3rd sealing lip 7, the first sealing lips 5 are close to the outside face of described sealing inner ring 3, and second sealing lip 6 is close to the side of described sealing inner ring 3; First sealing lip 5, second sealing lip 6 and described sealing inner ring 3 surround the inside face that first annular seal space, 10, the three sealing lips 7 are close to described sealing inner ring 3, and the 3rd sealing lip 7, second sealing lip 6 and described sealing inner ring 3 surround second annular seal space 11; Described sealing inner ring 3 and wheel shaft 2 interference fit, described sealed outer ring 4 and roller 1 interference fit.
Present embodiment is because sealing lip makes two parts contacts of mutual motion under the elastic force effect, there is not the gap between the parts of two relative motions, simultaneously, first annular seal space 10, second annular seal space 11 can play twice seal isolation effect, can effectively avoid extraneous dust and water to enter into the position that roller 1 cooperates with wheel shaft 2, the sealing effectiveness ideal has reduced the maintenance cost of escalator, improves the service life of escalator roller and wheel shaft.
