Abstract
The utility model discloses a novel sealing structure of a belt conveyor carrier roller. The novel sealing structure of the belt conveyor carrier roller comprises inner sealing rings, outer sealing rings, hole check rings and shaft check rings. The novel sealing structure is characterized in that the inner sealing rings and the outer sealing rings are made of fluororubber and provided with lip-shaped opening parts, and hooping springs are arranged in the lip-shaped opening parts. The portion between a bearing pedestal and a shaft at each end of a roller body is sleeved with one inner sealing ring and one outer sealing ring which are symmetrically distributed on the inner side and the outer side of a carrier roller bearing. The portion, between the inner end face of each outer sealing ring and the carrier roller bearing, of a shaft is sleeved with one shaft check ring, and the portion, between the outer end face of each inner sealing ring and the carrier roller bearing, of the shaft is sleeved with one hole check ring. The novel sealing structure is simple in structure, convenient to manufacture and low in cost, and professional equipment is not needed. Meanwhile, the sealing rings are provided with the very large lip parts and the hooping springs, so that the sealing effect beyond comparison with other structures is obtained. The sealing rings are made of the fluororubber, and therefore in comparison with sealing rings made of other common rubber, service life is prolonged by over 5 times.
Description
Technical field
The utility model relates to the belt conveyer field, relates in particular to a kind of novel sealing structure of carrier roller of belt conveyer.
Background technology
Belt conveyer is most widely used a kind of equipment in continuous conveyor, and its structure is by driving drum, bend pulley, and carrying roller, the parts such as actuating device and belt form.And carrying roller maximum parts that are consumptions are distributed in complete machine whole process, its quality will affect the running quality of complete machine, be also national expert engineer's research emphasis.The carrying roller of domestic each professional production manufacturer production, be generally the labyrinth seal structure that adopts Ministry of Machine-Building Industry's design at the end of the seventies at present, is comprised of seven sealing original papers.Although its leak tightness is better, complex structure, sealing effectiveness are subjected to the quality of each obturator and the impact of installation quality, and make and need use professional equipment, and investment cost is high.
The utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of novel sealing structure of carrier roller of belt conveyer is provided, and it is simple in structure, and sealing property is good, and long service life just can be made without specialized equipment.
The utility model is achieved through the following technical solutions:
A kind of novel sealing structure of carrier roller of belt conveyer, include inner seal ring, exterior seal ring, the hole back-up ring, shaft block ring, it is characterized in that: in described, exterior seal ring all adopts the viton material to make to have the lip oral area, and in the lip oral area, be provided with the banding spring, in described, exterior seal ring is sleeved between the bearing seat and axle at roll body two ends, and be symmetrically distributed in the inside and outside both sides of Idler bearing, on the inner end surface of described exterior seal ring and the axle between Idler bearing, be set with shaft block ring, the porose back-up ring of using of suit on the outer face of described exterior seal ring and the axle between bearing seat.
The lip oral area of described inside and outside seal ring is close to respectively the surface of roller carrier shaft.
Its effect of described inner seal ring is to prevent that the grease in bearing bore inwardly runs off, and its effect of described exterior seal ring is to prevent that the grease in bearing bore outwards runs off, and stops simultaneously extraneous rainwater, and dust enters in bearing bore.Described hole is that the restriction exterior seal ring moves axially with back-up ring, and described shaft block ring is to limit the bearing longitudinal travel.
In the inside and outside both sides of Idler bearing, respectively place a rotary shaft lip seal, seal ring adopts the new material viton to make, and lip and banding spring that resilience is very strong are arranged.And the lip of seal ring and its in relative rotation axle be gap-free sealed, and lip banding spring to the enclasping force of axle overcome axle under slew mode because of runout, the gap of beating and causing, make the lip of sealing member be close to all the time the axle surface.The seal ring of described bearing internal external side makes the grease of bearing bore inside can inwardly or outward not run off, and the seal ring in the bearing outside has also stopped extraneous rainwater simultaneously, and dust enters in the Idler bearing chamber, thereby obtains sealing effectiveness preferably.
The utility model has the advantages that:
The utility model is simple in structure, easy to make, cost is low, without professional equipment, ring structure has very large lip and banding spring simultaneously, thereby obtain the sealing effectiveness that other structure can't be compared, seal ring adopts the new material viton to make, and compares other General Purpose Rubber life-span and improves more than 5 times.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the partial enlarged drawing in Fig. 1.
The specific embodiment
Referring to accompanying drawing, a kind of novel sealing structure of carrier roller of belt conveyer, include inner seal ring 1, exterior seal ring 2, hole back-up ring 3, shaft block ring 4, in, exterior seal ring 1, 2 all adopt the viton material to make has lip oral area 5, and in lip oral area 5, be provided with banding spring 6, in, exterior seal ring 1, 2 are sleeved between the bearing seat 9 and axle 8 at roll body two ends, and be symmetrically distributed in the inside and outside both sides of Idler bearing 7, on axle 8 between the inner end surface of exterior seal ring 2 and Idler bearing 7, be set with shaft block ring 4, on axle 8 between the outer face of exterior seal ring 2 and bearing seat 9, suit is porose with back-up ring 3.The lip oral area of described inside and outside seal ring 1,2 is close to respectively the surface of axle 8.
Claims (2)
1. the novel sealing structure of a carrier roller of belt conveyer, include inner seal ring, exterior seal ring, the hole back-up ring, shaft block ring, it is characterized in that: in described, exterior seal ring all adopts the viton material to make to have the lip oral area, and in the lip oral area, be provided with the banding spring, in described, exterior seal ring is sleeved between the bearing seat and axle at roll body two ends, and be symmetrically distributed in the inside and outside both sides of Idler bearing, on the inner end surface of described exterior seal ring and the axle between Idler bearing, be set with shaft block ring, the porose back-up ring of using of suit on the outer face of described exterior seal ring and the axle between bearing seat.
2. the novel sealing structure of a kind of carrier roller of belt conveyer according to claim 1, it is characterized in that: the lip oral area of described inside and outside seal ring is close to respectively the surface of roller carrier shaft.
