Abstract
The utility model discloses a carrying roller sealing structure comprising a roller, a carrying roller shaft and bearings; wherein tubular bearing seats are fixedly welded at two ends of the roller respectively, two ends of the carrying roller shaft respectively pass through a bottom hole of the corresponding bearing seat; the bearings are respectively sleeved at two ends of the carrying roller shaft and are pressed in bottoms of the corresponding bearing seats; an inner sealing ring is provided between a bottom surface of the corresponding bearing seat and the bearing, end faces at two sides of the each inner sealing ring are both provided with inner annular grooves and outer annular grooves; and opening parts of the two bearing seats are respectively provided with a sealing ring, a block ring is arranged between the corresponding bearing and the sealing ring and sleeved on the carrying roller shaft. The carrying roller sealing structure of the utility model has the beneficial effects that: the carrying roller sealing structure has the advantages of convenient installation and good sealing effect; the carrying roller sealing structure can eliminate axial movements of the carrying roller and can raise axial bearing of the carrying roller; the carrying roller sealing structure also can increase difficulty of water, dust and other garbage to enter into a bearing chamber, thereby effectively protecting the bearing; therefore, the carrying roller sealing structure can protect the bearing better.
Description
Technical field:
The utility model relates generally to the sealing arrangement of belt conveyer carrying roller centre bearer, relates in particular to a kind of carrying roller hermetically-sealed construction.
Background technology:
The belt conveyer carrying roller is the vitals of belt conveyer, and kind is many, and quantity is big.It has accounted for 35% of a belt conveyer total cost, born the resistance more than 70%, so the quality of carrying roller is particularly important.The effect of carrying roller is support belt and weight of material, and the carrying roller running must flexibility and reliability.Reduce the friction force of load-transfer device and carrying roller, life-span of load-transfer device is played key role.Bearing in the carrying roller is a core component, is important strut member and revolving part, and in a single day bearing lost efficacy, and whole carrying roller scrapped.So protection seems particularly important to the bearing felt in the carrying roller.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of structure design carrying roller hermetically-sealed construction cleverly to be provided.
The utility model is realized through following technical scheme:
A kind of carrying roller hermetically-sealed construction includes roller, roller carrier shaft and bearing, it is characterized in that: the roller two ends are fixedly welded with the bearing seat of tubular respectively, and said roller carrier shaft two ends are passed respectively in the bottom outlet of respective shaft bearing; Said bearing is enclosed within the roller carrier shaft two ends respectively and is pressed into cooresponding bearing seat bottom; Be provided with inner seal ring between respective shaft bearing bottom surface and the bearing, be equipped with the inner and outer rings connected in star on the both sides end face of each inner seal ring; The oral area of two bearing seats is separately installed with seal ring, has shield ring sleeve to be contained on the roller carrier shaft between cooresponding bearing and the seal ring.
A kind of carrying roller hermetically-sealed construction; It is characterized in that: the cover cap and the protective cover that has groove that include flared flange; Be placed in after said cover cap and the protective cover combine and assemble on the roller carrier shaft in the seal ring outside; Said cover cap obvolvent outside seal ring and and seal ring between be formed with the annular the stored chamber, be formed with between cover cap and the protective cover annular the external storage chamber.
A kind of carrying roller hermetically-sealed construction is characterized in that: said seal ring includes labyrinth inner seal ring and the labyrinth exterior seal ring that cooperatively interacts, and the cylindrical of labyrinth inner seal ring and the endoporus of bearing seat adopt interference fit; The endoporus of labyrinth exterior seal ring and the cylindrical of roller carrier shaft adopt interference fit.
Said bearing seat is punch forming, directly welds on the roller, and roller carrier shaft passes the bottom outlet of bearing seat, between the bottom surface of bearing seat and bearing, a symmetrical inner seal ring is arranged, and is the back-up ring of the axle usefulness of thickening in the outside of bearing, be fixed type bearing and spool effect.The outside of shaft block ring is the inside and outside seal ring of being made up of the multiple tracks labyrinth in contactless labyrinth; The outer ring of labyrinth inner seal ring is had the cover cap of flared flange and is held tightly; In the outside of cover cap is the protective cover that has groove, and inside and outside labyrinth seal, cover cap are hidden protection.
Said symmetrical inner seal ring; Need not to recognize left and right directions; Easy for installation, the effect of the inner and outer rings connected in star on the end face of inner seal ring both sides is respectively: store the grease that supplies bearing lubrication and store the rubbish owing to the corrosion generation of roller inwall, stop rubbish to get into bearing chamber.
Said back-up ring is installed between the inside and outside seal ring of bearing and labyrinth, and the ability actv. guarantees the location of bearing and roller carrier shaft, eliminates the axial carrying of carrying roller end float misalignment, raising carrying roller; The inside and outside seal ring in contactless labyrinth that the multiple tracks labyrinth is formed, inside and outside seal ring noncontact can guarantee that carrying roller rotates flexibly, and rotational resistance is little, and the multiple tracks labyrinth can effectively stop water, dust and other rubbish to get into the bearing chamber position.
The external diameter of said cover cap and inner hole of bearing seat interference fit, the endoporus of protective cover, labyrinth exterior seal ring and the external diameter interference fit of roller carrier shaft, anti-sealing, dust and other rubbish get into the bearing chamber position through the gap of its cooperation.
Have the external storage chamber of cover cap between the protective cover that has groove of flared flange to form the labyrinth, the stored chamber that the outside of the inboard of cover cap and labyrinth outer gland sealing forms can store more rubbish, reduces the chance that rubbish gets into bearing chamber.
The utility model has the advantages that:
The utility model is easy for installation, good sealing effect; Can eliminate the axial carrying of carrying roller end float misalignment, raising carrying roller; Increase the difficulty that water, dust and other rubbish get into bearing chamber, effectively protect bearing; Bearing is played better protection.
