Abstract

The utility model discloses a labyrinth seal seat for a carrier roller. An annular bulge is formed at the outer periphery of one end of an aluminum alloy bearing seat; a bearing chamber with a step-shaped axial through hole is formed in the middle of an aluminum alloy labyrinth seal seat; a step-shaped axial through hole is formed in the middle of a plastic labyrinth seal ring; three bulge rings and two groove ring structures are formed in the outer circumference of one end of the through hole in sequence; the aluminum alloy labyrinth seal seat takes the shape of a regular-triangle equal-diameter equilateral cylinder; an axially equal-diameter through hole is formed in the middle of the aluminum alloy labyrinth seal seat; three bulge rings, two groove rings and a step ring are alternatively formed in one end of the through hole from inner circumference to outer circumference in sequence. The labyrinth seal seat of the carrier roller is simple and reasonable in structure, very convenient to assemble and disassemble, very good in seal performance, and very long in service life; the recycling rate of aluminum alloy is high to 99%.

Description

A kind of carrying roller labyrinth seal seat
Affiliated technical field
The utility model relates to a kind of sealing seat, particularly a kind of carrying roller labyrinth seal seat.
Background technique
Current supporting roller sealing seat is on the market all the material that uses the conduct cylinder skin of aluminum alloy, and its anti-corrosion capacity is poor, and after corrosion, dismounting is very difficult, reclaim very inconvenient, only have completely discardedly, waste very much resource, and its unreasonable structure, sealing is very poor, affects its working life.
Summary of the invention
In order to solve in actual use, some problems that traditional sealing seat exists, the utility model provides a kind of carrying roller labyrinth seal seat, compared with this labyrinth seal seat sealing seat traditional with other, outside cylinder skin uses the resistant material of non-metallic material, inner structure is than traditional labyrinth seal seat advantages of simple more, and assembly and disassembly is very convenient, sealability is good especially, labyrinth seal seat can also be taken apart recycling after no longer continuing to use very easily, and its aluminum alloy recovery utilization rate is up to 99%.
The utility model solves the technological scheme that its technical problem adopts: this one carrying roller labyrinth seal seat comprises aluminum alloy labyrinth seal seat, plastics labyrinth seal, aluminum alloy bearing seat, this aluminum alloy labyrinth seal seat is an isometrical right cylinder shape, be provided with the protruding platform of a ring in the outside of aluminum alloy bearing seat one end, projection platform inwardly forms the groove of a ring, the middle part of aluminum alloy labyrinth seal seat is a bearing chamber with step-like axial hole, bearing can be arranged in bearing chamber accurately, described plastics labyrinth seal is an isometrical right cylinder shape, there is a step-like axial through hole at plastics labyrinth seal middle part, this through hole one end excircle, be sequentially with three road protruding rings and twice groove ring structure, the protruding ring end of outermost can head on the outer shroud of bearing, the installation that is accurately connected of its outside and aluminum alloy labyrinth seal seat inwall, all the other twice protruding rings and bearing have pulled open a segment distance, described aluminum alloy labyrinth seal seat is the isometrical right cylinder shape of a Pin form, this aluminum alloy sealing seat middle part is provided with axially isometrical through hole, this through hole and roller shaft precision-fit are installed, at one end of through hole circumference from inside to outside, sequence alternate is provided with three road protruding rings, twice groove ring and a circle step ring, the protruding ring of its innermost circle can push up is pressing bearing inner ring, plastics labyrinth seal after all the other twice protruding rings and installation and aluminum alloy labyrinth seal seat have pulled open distance, mutually do not contact.
The beneficial effects of the utility model are, this carrying roller is compared other traditional labyrinth seal seats with labyrinth seal seat, internal structure is advantages of simple more, outside cylinder skin material is nonmetallic corrosion-resistant plastic, and whole aluminum alloy labyrinth seal seat assembly and disassembly is very convenient, and sealability is very good, working life is long especially, labyrinth seal seat can also be taken apart after no longer continuing to use, classification recycling, and its aluminum alloy recovery utilization rate is up to 99%.
