Abstract
A nonmetal-metal combined carrier roller comprises a roller, a bearing pedestal, a shaft, a bearing and a seal ring, wherein the bearing pedestal is arranged at the two ends of the roller; the shaft is arranged in the bearing pedestal at the two ends of the roller; the roller is made of polyvinyl chloride; strengthening ribs are arranged on the inner wall of the roller along the axis thereof; the bearing pedestal is made of steel; long circular holes formed on the side wall of the bearing pedestal are matched with the strengthening ribs on the inner wall of the roller; the bearing pedestal is pressed in the roller in an interference manner; and end parts of the strengthening ribs on the inner wall of the roller are connected with the bearing pedestal in a hot riveting manner. In the carrier roller, the nonmetallic roller is combined with the metal bearing pedestal, so that the weight of the roller is reduced, the corrosion resistance of the carrier roller is improved, at the same time, the coaxiality of the roller and the bearing pedestal of the carrier roller is guaranteed, the radial run-out is reduced, and the service life of the carrier roller is prolonged; the strengthening ribs are arranged on the inner wall of the roller along the axis thereof, so that the strength of the roller is improved; and the long circular holes on the side wall of the bearing pedestals are matched with the strengthening ribs in the roller to facilitate the hot riveting connection therebetween.
Description
Technical field:
The utility model relates to the article feeding device, particularly has the belt conveyer of carrying roller turning unit, specifically is a kind of non-metal-melts combine formula carrying roller.
Background technology:
Carrying roller is the maximum turning unit of belt conveyer consumption, is widely used in various working conditions such as colliery, mine, harbour.In the prior art, the metal carrying roller uses more, but common metal carrying roller weight is big, rotational resistance is high, corrosion-resistant; Metal carrying roller and adhesive tape friction produce static, adsorb Iron Ore Powder and dust, have strengthened the friction force of carrying roller and load-transfer device, have shortened the life-span of metal carrying roller and load-transfer device; The metal carrying roller easily gets rusty in harsies environment such as soda acid, contaminated material.And that the non-metal carrying roller generally connects technology is comparatively complicated, and non-metal carrying roller roller generally adopts glue bond to add pin with the connection mode of bearing seat to be connected, and the process structure complexity is difficult to effectively guarantee the right alignment of carrying roller and bearing seat, influences the service life of carrying roller.
The utility model content:
The purpose of this utility model is to provide a kind of non-metal-melts combine formula carrying roller, described this non-metal-melts combine formula carrying roller will solve that metal carrying roller weight of the prior art is big, rotproofness is poor, service life is short, and the roller of non-metal carrying roller and the right alignment of bearing seat are difficult for the technical matters in assurance and then shortening carrying roller service life.
The purpose of this utility model is achieved through the following technical solutions: comprise that roller, bearing seat, axle, bearing and seal ring constitute, bearing seat is located at the roller two ends, axle is located in the bearing seat at roller two ends by bearing, seal ring is located at the outer end of bearing seat by jump ring, wherein, this roller is made of polyvinylchloride, the roller inwall is provided with the reinforced rib along its axis, bearing seat is made of steel, this bearing seat sidewall is provided with the Long Circle hole and matches with the reinforced rib of roller inwall, and bearing seat press-fits in roller by the interference mode.
The end of roller inwall reinforced rib is connected with bearing seat by the hot riveting mode.
The reinforced rib quantity of roller inwall is 8, and these 8 reinforced ribs evenly are provided with along the roller circumferencial direction, and the bearing seat sidewall is provided with 8 Long Circle holes, and this 8 Long Circle hole evenly is provided with along the bearing seat circumferencial direction.
The contacted sidewall of seal ring and bearing seat is provided with the annular seal space that is three road bendings.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model adopts the non-metal roller to combine with the metal shaft bearing in carrying roller, is interference fit between bearing seat and the roller, reduces the weight of roller, increase the corrosion stability of carrying roller, guarantee the right alignment of carrying roller roller and bearing seat simultaneously, reduced radial runout, prolonged carrying roller service life; Be provided with along its axial reinforced rib at the roller inwall, increase the intensity of roller, can reduce the wall thickness of roller like this and can not influence the intensity of roller, thereby can reduce roller weight; The reinforced rib that the bearing seat sidewall is offered in Long Circle hole and the roller matches, and the assembling of being convenient to the two connects.Adopt the hot riveting mode to be connected between bearing seat and the roller, only local noncontact heating plasticizing is carried out in the riveting stake, cold die head touch riveting be shaped again the cooling after promptly realized being fastenedly connected, no spillage of material, no waste material produces, friction and noise, the assembly staking of metal shaft bearing and non-metal roller can be assembled into one, riveted joint face is attractive in appearance, degree of finish good, be difficult for the be full of cracks embrittlement, be connected firmly, simplified production technology, reduced material consumption, greatly improved the quality of products, reliability and production efficiency, increase the service life effectively.At the roller inwall 8 reinforced ribs are set evenly, can make roller intensity even, further reduce the weight of roller wall thickness and cylinder, simultaneously evenly offer on the bearing seat Long Circle hole match with reinforced rib on the roller with.Annular seal space with three bendings is set between seal ring and the bearing seat sidewall, improves sealing property, dustproof, the water resistance effect is obvious, the withstand voltage 29000N that reaches.
