Abstract
The utility model provides a carrier roller, comprising an outer tube and a central axis. The two ends of the outer tube are provided with bearing chocks; the bearing chocks are connected with the outer tube; the bearing chocks are provided with bearings; and the bearings are connected with the bearings chocks and the central axis. The utility model is characterized in that: a labyrinth seal inner ring and a labyrinth outer ring is arranged on the end of the central axis in turn from the center to the out; the labyrinth seal inner ring and the outer ring is connected with the central axis; a labyrinth seal middle ring is arranged between the labyrinth seal inner and outer rings; and the labyrinth middle ring is connected with the bearing chock. Compared with the prior art, the combine structure of two labyrinth seal rings in the carrier roller maximize the dust-proof scope, effectively stops dust, water and other things entering into the carrier roller, greatly increases the leak tightness, reduces the abrasion, and prolongs the service life of the carrier roller.
Description
Technical field
The utility model relates to a kind of carrying roller, belongs to belt transportation machinery equipment part.
Background technology
Its outside of existing belt transporter carrying roller is generally metal or non-metal body, and sealed at both ends property is not strong, in such as many abominable working environments such as underground mines, a large amount of slags, dust, water etc. not only corrode the exterior tubular body of carrying roller, and can enter carrying roller inside, cause seriously to stop up and wear and tear, influence the carrying roller normal operation, must clear up continually, overhaul and change, carrying roller generally has only 1-2 service life, and the goods and materials waste is very big.
Summary of the invention
The purpose of this utility model is to improve the deficiencies in the prior art parts, and the novel carrying roller of a kind of wear-resistant, good airproof performance, long service life is provided.
The technical solution of the utility model is, a kind of carrying roller, it comprises outer tube body and center shaft, two ends at outer tube body are provided with bearing seat, bearing seat is captiveed joint with outer tube body, be provided with bearing in the bearing seat, bearing and bearing seat, center shaft are abutted against, characteristics are, end at center shaft is provided with labyrinth packing inner ring and labyrinth packing outer ring from inside to outside successively, the labyrinth packing inner ring is captiveed joint with center shaft with the labyrinth packing outer ring, is provided with the labyrinth packing centre circle between labyrinth packing inner ring and labyrinth packing outer ring, and the labyrinth packing centre circle is captiveed joint with bearing seat.
Compared with the prior art, three array modes are adopted in the labyrinth packing at the utility model carrying roller two ends, positive and negative two cover labyrinth packing unitized constructions have been formed, make dustproof path reach maximization, stop dust, water etc. to enter carrying roller inside effectively, sealing property is very good, has reduced wearing and tearing, prolongs carrying roller service life.
Below in conjunction with drawings and Examples, the utility model is at length explained.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 outer tube body, 2 bearing seats, 3 labyrinth packing outer rings, 4 trip rings, 5 labyrinth packing centre circles, 6 bearings, 7 labyrinth packing inner rings, 8 metal inserts, 9 center shafts.
Specific embodiments
Referring to accompanying drawing, outer tube body 1 can adopt that the multilayer material that comprises metal and non-metal is compound to be made, this body rigidity is strong, both wear-resisting, be difficult for corrosion again, service life is more many than will prolonging of metal or non-metal body, at the two ends of outer tube body 1 fixed installation bearing seat 2, place bearing 6 in it, bearing 6 and bearing seat 2, center shaft 9 is abutted against, two ends at center shaft 9 are installed labyrinth packing inner ring 7 and labyrinth packing outer ring 3 from inside to outside successively, labyrinth packing inner ring 7 is captiveed joint with center shaft 9 with labyrinth packing outer ring 3, a labyrinth packing centre circle 5 is set between labyrinth packing inner ring 7 and labyrinth packing outer ring 3 again, labyrinth packing centre circle 5 is fixedly connected on the bearing seat 2, labyrinth packing outer ring 3 can double as carrying roller two ends end cap, on labyrinth packing outer ring 3, mounting spring back-up ring 4 between labyrinth packing inner ring 7 and the bearing 6 is coated with into grease in the gap that three labyrinth seals form.Carrying roller of the present utility model is when running work, and the labyrinth packing unitized construction of its positive and negative two covers can make dustproof path reach maximization, and leak tightness is very good.
In order to reach dustproof better effect, can also all make circular-arc with the collar extension place of labyrinth packing outer ring 3 labyrinth packing centre circle 5, form circular-arc gap between the two, make extraneous dust, moisture be difficult for entering, and the dust, the moisture that have entered are thrown away easily.
The utility model can also be provided with metal insert 8 in bearing seat 2, metal insert 8 is fixedly mounted on a side of close bearing 6 on the bearing seat 2, both can increase the rigidity of bearing seat 2, can guarantee again the diaxon bearing hole install and use in size and the conformability of position.
