Abstract
The utility model discloses a processing-free notch and durable idler roller, which comprises a bearing arranged on a shaft, and a bearing seat, wherein the outer side of the bearing seat is provided with a roller barrel, one side of the bearing is provided with a sealing structure, the bearing seat and the roller barrel forms an interference fit, barrel ports of both ends of the outer side of the roller barrel are even ports without adopting notches and the sealing structure is a gap type sealing structure provided with at least two bent paths. The utility model is pressed through the interference fit so as to overcome the radial bouncing deformation of the ports of the roller barrel and extend the service life of the processing-free notch and durable idler roller; the barrel port of both ends of the roller barrel adopt the even ports without the notches so that the utility model reduces a processing program and reduces manufacturing cost; the utility model adopts the gap type sealing structure so as to prevent water and dust from entering the idler roller bearing and extend the service life of the processing-free notch and durable idler roller, and can be widely used for various types of conveyers.
Description
Technical field
The utility model relates to mechanical moving device, relates in particular to a kind of ribbon conveyer carrying roller of adhesive tape up and down.
Background technology
Ribbon conveyer is widely used in metallurgy, the mine, coal, the harbour, the power station, the cement mill, a plurality of industries such as harbour, be used to carry various loose unpacked materials and member article, carrying roller is to be used for the material that carries on support belt and the load-transfer device, and the device of assurance load-transfer device smooth running, also be to use the critical component in the process, it is dustproof, waterproof and rotational resistance are three important indicators indicating capability and performance, existing labyrinth seal structure carrying roller, in case water intrusion, the oil film breakdown in labyrinth, enter bearing until water and dust and cause total to be scrapped, therefore how to improve the dustproof of carrying roller, waterproof ability is the difficult problem of puzzlement technical personnel always.Publication number is that the Chinese patent of CN2259383 discloses sealing idler roller in, adopt Z-shaped protective cover and within it side the purpose that boss reaches water proof and dust proof is set; Publication number is that the Chinese patent of CN2259382 discloses a kind of carrying roller that has the centrifugal seal structure, by the purpose that butterfly circle, the saturating lid in location and lubricating disc reach water proof and dust proof is set, but above-mentioned all devices all press-fit by the form of idler roll bucket seam with free-running fit when bearing is located, cause between bearing and the roller bucket wall and enter water and dust easily, further influence the carrying roller life-span.
Summary of the invention
The utility model is exactly to provide a kind of reasonable in design, simple in structure exempting to process the seam support roller with long lifespan at above deficiency.
Technical solution adopted in the utility model is:
A kind ofly exempt to process the seam support roller with long lifespan and comprise bearing, the bearing seat that is located on the axle, the outside of bearing seat is provided with the roller bucket, and a side of bearing is provided with hermetically-sealed construction, and interference fit press-fits between bearing seat and the roller bucket.
The nozzle at described roller bucket two ends is neat mouthful, but not adopts seam.
Described hermetically-sealed construction is a lacuna formula hermetically-sealed construction.
At least be provided with two bends on the inner seal ring of described hermetically-sealed construction and the exterior seal ring.
The good effect that can reach of the present utility model is:
1, the utility model is reasonable in design, simple in structure, easy to install and use.
2, the utility model adopts interference fit to press-fit, and has overcome the radial runout distortion of roller bung preferably, has prolonged the service life of carrying roller.
3, the nozzle at the utility model roller bucket two ends adopts neat mouthful but not seam has reduced work programme, has reduced manufacturing cost.
4, the utility model adopts lacuna formula hermetically-sealed construction, and anti-sealing of actv. and dust enter Idler bearing inside, have improved the service life of carrying roller.
Description of drawings
Fig. 1 is two bend leak free idler structure section-drawings;
Fig. 2 is three bend leak free idler structure section-drawings;
Wherein: 1, bearing; 2, roller bucket; 3, Qi Kou; 4, bend; 5, hermetically-sealed construction; 6, bearing seat; 7, axle.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
By Fig. 1, Fig. 2 as seen, this is exempted to process the seam support roller with long lifespan and comprises the bearing 1 that is located on the axle 7, bearing seat 6, the outside of bearing seat 6 is provided with roller bucket 2, one side of bearing 1 is provided with hermetically-sealed construction 5, bearing seat 6 adopts interference fit to press-fit with roller bucket 2, so just overcome the radial runout distortion of roller bucket 2 mouthfuls, prolong the service life of carrying roller, the nozzle at roller bucket 2 two ends is neat mouthful 3, but not adopts seam, can reduce work programme like this, reduce manufacturing cost, hermetically-sealed construction 5 adopts the lacuna formula hermetically-sealed construction 5 that is provided with two or three bends 4 on inner seal ring and the exterior seal ring at least, and anti-sealing and dust enter Idler bearing 1 inside, improve the service life of carrying roller.
