Abstract
The utility model provides a carrier roller used for a belt conveyor and capable of avoiding a clearance appearing between a roller and a bearing block. The carrier roller comprises the roller (5) anda support shaft (1), wherein the roller (5) is sleeved on the support shaft (1) through a bearing (7) and the bearing block (6); the outside of the bearing (7) is provided with a sealing structure; the bearing block (6) is made of the same material as that of the roller (5); and fitting surfaces of the bearing block (6) and the roller (5) are in seamless connection. The carrier roller is suitablefor various belt conveyors, in particular belt conveyors under working conditions of humidity and a great deal of dust underground and the like.
Description
Technical field
The utility model relates to a kind of belt transporter, especially a kind of carrying roller that is used for belt transporter.
Background technology
Carrying roller is the critical component of band conveyor, comprises roller, pivot shaft, and roller is contained on the pivot shaft by bearing and bearing sleeve thereof, and the bearing arranged outside has hermetically-sealed construction.
Present carrying roller roller mostly is nylon and makes, and roller and bearing seat adopt gluing mode to be connected usually, so roller and bearing seat tolerance clearance are big, and the adhesive means Joint strenght is low.In use, roller and bearing seat constantly change owing to the load-bearing direction, the all directions repeated deformation causes the gaping of joints between roller and the bearing seat to produce the slit, thereby cause dust to enter carrying roller inside from the slit, cause seal failure, when serious even cause the connection between roller and the bearing seat to be lost efficacy.
The utility model content
Existing not enough in order to overcome, technical problem to be solved in the utility model provides a kind of carrying roller that can avoid occurring between roller and the bearing seat slit.
The technical scheme that its technical matters that solves the utility model adopts is: the carrying roller that is used for belt transporter, comprise roller, pivot shaft, described roller is contained on the pivot shaft by bearing and bearing sleeve thereof, described bearing arranged outside has hermetically-sealed construction, described bearing seat adopts identical material with roller to make seamless link between bearing seat and the roller fitting surface.
The beneficial effects of the utility model are: bearing seat adopts identical material with roller, and the coefficient that thermal expansion coefficient, plastoelastic deformation are correlated with is all identical, and by seamless link, has avoided the generation in slit.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the partial enlarged drawing in Figure 1A zone.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1 and Figure 2, the carrying roller that is used for belt transporter of the present utility model, comprise roller 5, pivot shaft 1, described roller 5 is sleeved on the pivot shaft 1 by bearing 7 and bearing seat 6 thereof, described bearing 7 arranged outside have hermetically-sealed construction, described bearing seat 6 adopts makes seamless link between bearing seat 6 and roller 5 fitting surfaces with roller 5 identical materials.
Concrete, described roller 5 and bearing seat 6 adopt nylon to make.Nylon is the modification of nylon through antifriction, antistatic, right, the anti-stick modification of resistance.Antifriction can increase service life; Antistatic, resistance so makes this carrying roller can be applicable to the colliery down-hole application; Anti-adhesive properties is then avoided this carrying roller adsorption dust, has guaranteed the circular degree of carrying roller, has guaranteed the steady of transportation, has further strengthened the corrosion stability of carrying roller simultaneously.
Compare with traditional metallic material, bearing seat 6 and roller 5 adopts identical nylon to make, and wear resistant corrosion resistant can not scratch belt, and bearing seat 6 and roller 5 thermal expansion coefficient, plastoelastic deformation coefficient are all identical, the generation in slit when having avoided operation.And, connect better effects if because elasticity, the good toughness of nylon are more suitable for carrying out the seamless link of flush fit form.Certainly except adopting nylon material, according to the requirement of different use occasions, carrying roller also can adopt the Other Engineering plastics, as polyethylene, PVC, polypropylene, polyformaldehyde, polycarbonate etc.
And pass through from bonding seamless link between above-mentioned bearing seat 6 and roller 5 fitting surfaces.Be similar to the metallo-welding from bonding seamless link, thereby make bearing seat 6 and roller 5 can combine the Joint strenght height together.Can certainly carry out seamless link by other modes such as ringfeders.
Concrete, above-mentioned hermetically-sealed construction is the labyrinth gland 4 that is made of wrong exterior seal ring of stinging 43 of intersection and inner seal ring 42.Exterior seal ring 43 is fixed on the bearing seat 5, and inner seal ring 42 is fixed on the pivot shaft 1, and the gap between exterior seal ring 43 and the inner seal ring 42 is full of seal grease.Compare with rubber skeleton formula oil sealing, felt formula oil sealing, tightening seal washer etc., labyrinth gland 4 sealing effectivenesss are better, and labyrinth packing belongs to non-contacting seal, and it is littler to wear and tear, and durability is better.
In order to guarantee that the seal grease in the labyrinth structure can reach additional, thereby guarantee sealing effectiveness, above-mentioned labyrinth gland 4 inboards are provided with the oil pocket 41 that is communicated with exterior seal ring 43 and inner seal ring 42 tolerance clearances.
For simplified structure, above-mentioned oil pocket 41 also with bearing 7 inner ring outer rings between the rolling body cavity be communicated with, guaranteed replenishing of bearing 7 lubricating greases when the seal grease in guaranteeing labyrinth structure replenishes.
Concrete, above-mentioned labyrinth gland 4 adopts to be made with roller 5 identical materials, owing to adopted identical nylon material, when strengthening Joint strenght, toughness is better.When carrying roller is worked, compare with traditional metal material, can prevent between exterior seal ring 43 and the inner seal ring 42, occur between inner seal ring 42 and the bearing 7 very stiff and demanding, can prevent that bearing 7, labyrinth gland 4 that metal filings causes are stuck, better effects if to pivot shaft 1 floating compensation, guarantee the normal operation of transport plane, and had wear-resisting, withstanding corrosion, the advantage of binding dust not equally, prolonged the average accident-free duration of transport plane.
In order further to strengthen sealing, above-mentioned labyrinth gland 4 arranged outside have cover of dust 3.Cover of dust 3 is stuck between ring washer 2 and the labyrinth gland 4 by the ring washer 2 of pivot shaft 1, thereby make the gap of exterior seal ring 43 and inner seal ring 42 innermost layers be isolated from the outside by cover of dust 3, and form another labyrinth mechanism before by the staggered labyrinth gland 4 that is engaged in of cover of dust 3 and inner seal ring 42.
Above-mentioned cover of dust 3 adopts to be made with roller 5 identical materials, also is nylon material.Prevent that further 3 pairs of exterior seal rings 43 of cover of dust from causing scuffing, guaranteed the sealing effectiveness of hermetically-sealed construction, and have wear-resisting, withstanding corrosion, the advantage of binding dust not equally.
The maintenance of carrying roller for convenience, above-mentioned bearing seat 6 endoporus are stepped holes, the aperture axially increases from inside to outside step by step along roller 5.Outwards, bearing 7 is fixed by first order step in having, and hermetically-sealed construction is fixed on second stage platform, therefore can remove hermetically-sealed construction and bearing 7 very easily.
Above-mentioned inside and outside, inboard, the outside, all be by along roller carrier shaft to the inside and outside definition of carrying roller.
