Abstract
The utility model discloses the sealing device of a bearing in a belt conveyer supporting roller, which comprises a roller, a supporting roller shaft and bearings. The two ends of the roller are respectively and fixedly welded with tubular bearing seats. The two ends of the supporting roller shaft respectively pass through the bottom holes of the corresponding bearing seats. The bearings are respectively sleeved onto the two ends of the supporting roller shaft and are pressed into the bottoms of corresponding bearing seats. The mouth parts of the two bearing seats are respectively provided with a sealing ring. A retaining ring respectively arranged between a bearing and its corresponding sealing ring is sleeved onto the supporting roller shaft. Due to the adoption of the sealing device, the axial movement of a supporting roller is eliminated and the axial bearing capability of the supporting roller is improved. Meanwhile, water, dusts and other waste are more difficult to enter a bearing chamber, so that bearings are effectively protected. The sealing device is strong in bearing capacity and low in production and manufacture cost.
Description
Technical field:
The utility model relates generally to a kind of sealing arrangement of belt conveyer carrying roller centre bearer.
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 sealing arrangement of belt conveyer carrying roller centre bearer to be provided, its reasonable in design, good sealing effect.
The utility model is realized through following technical scheme:
A kind of sealing arrangement of belt conveyer carrying roller centre bearer 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; 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 sealing arrangement of belt conveyer carrying roller centre bearer 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.
A kind of sealing arrangement of belt conveyer carrying roller centre bearer; It is characterized in that: there is a flange outside of labyrinth inner seal ring, and the labyrinth exterior seal ring has an outer cover, and the flange of labyrinth inner seal ring matches with the outer cover of labyrinth exterior seal ring; Outer cover wraps up flange, forms the gap.
Said bearing seat is punch forming, directly welds on the roller, and roller carrier shaft passes the bottom outlet of bearing seat, and the direct mount bearing in the bottom surface of bearing seat is the back-up ring of the axle usefulness of thickening in the outside of bearing, is the effect of fixed type bearing and axle.The outside of back-up ring is the inside and outside seal ring of being made up of the multiple tracks labyrinth in contactless labyrinth.
Adopt technique scheme, bearing directly is fitted in the bottom of bearing seat, and 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 is installed in the oral area of bearing seat.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; There is a flange outside of labyrinth inner seal ring; The labyrinth exterior seal ring has an outer cover, and the flange of labyrinth inner seal ring matches with the outer cover of labyrinth exterior seal ring, and outer cover wraps up flange; Form less clearance, can prevent effectively that more sealing, dust and other rubbish get into the bearing chamber position.
The external diameter of labyrinth inner seal ring and inner hole of bearing seat interference fit, the external diameter interference fit of the endoporus of labyrinth exterior seal ring and roller carrier shaft prevent that sealing, dust and other rubbish get into bearing chamber through its tolerance clearance; There is a horizontal bar with holes at exterior seal ring endoporus place, labyrinth, through with the combination of labyrinth, labyrinth inner seal ring, with its inner cavity chamber's nature separated into two parts.Lean on bearing portions, but storing lubricating oil, for bearing provides lubricated; Another part, but storage compartment rubbish then.
In addition, the leak free part is few in the utility model, has only two of the inside and outside seal rings in labyrinth, and the cost of producing and make this structure carrying roller is low.Simultaneously, the degree of depth of bearing seat is more shallow, and the center of bearing is also shorter to the distance of the axle head of roller carrier shaft, and in the carrying roller operation process, the bearing seat of this structure can bear bigger reverse stress.Be that load-carrying capacity is stronger.
The utility model has the advantages that:
The utility model can be eliminated the carrying roller end float misalignment, improve the axial carrying of carrying roller; Increase the difficulty that water, dust and other rubbish get into bearing chamber, effectively protect bearing; Load-carrying capacity is strong, produces and low cost of manufacture.

Fig. 1 is the front view of the utility model.
Fig. 2 is the section-drawing of the utility model one end.
Wherein, 1, the ram axle bearing, 2, the labyrinth exterior seal ring, 3, the labyrinth inner seal ring, 4, back-up ring, 5, bearing, 6, roller carrier shaft, 7, roller.
The specific embodiment:
Referring to accompanying drawing.
A kind of sealing arrangement of belt conveyer carrying roller centre bearer includes roller 7, roller carrier shaft 6 and bearing 5, and roller 7 two ends are fixedly welded with the bearing seat 1 of tubular respectively, and said roller carrier shaft 6 two ends are passed respectively in the bottom outlet of respective shaft bearing 1; Said bearing 5 is enclosed within roller carrier shaft 6 two ends respectively and is pressed into cooresponding bearing seat 1 bottom; The oral area of two bearing seats 1 is separately installed with seal ring, has back-up ring 4 to be sleeved on the roller carrier shaft 6 between cooresponding bearing 5 and the seal ring.
Seal ring includes the labyrinth inner seal ring 3 and labyrinth exterior seal ring 2 that cooperatively interacts, and the endoporus of the cylindrical of labyrinth inner seal ring 3 and bearing seat 1 adopts interference fit; The cylindrical of the endoporus of labyrinth exterior seal ring 2 and roller carrier shaft 6 adopts interference fit.
There is a flange outside of labyrinth inner seal ring 3, and labyrinth exterior seal ring 2 has an outer cover, and the flange of labyrinth inner seal ring 3 matches with the outer cover of labyrinth exterior seal ring 2, and outer cover wraps up flange, forms the gap.
