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 carrying roller.
Background technology:
Carrying roller is the maximum turning unit of belt conveyer consumption.In the prior art, the metal carrying roller uses more, but common metal carrying roller weight is big, corrosion-resistant; And the non-metal carrying roller generally connects comparatively complexity of technology.In the existing non-metal carrying roller, the connection mode of non-metal carrying roller roller and bearing seat such as it is more that the polyvinylchloride carrying roller is used, polyvinylchloride is to concern the key factor of its quality.At present when producing the non-metallic material carrying roller, generally between roller and the bearing seat adopt glue bond to add pin to be connected, to select press-fiting of the magnitude of interference greatly simultaneously, 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 carrying roller, and described this non-metal carrying roller will solve idler structure of the prior art to be caused the difficult assurance of right alignment of processing technology complexity, carrying roller and bearing seat and then shorten the carrying roller technical matters in service life.
The purpose of this utility model is achieved through the following technical solutions: comprise roller, bearing seat and axle, bearing seat is located at the roller two ends, axle is located in the bearing seat at roller two ends by bearing, wherein, this roller inwall is provided with the reinforced rib along its axis, roller endoporus two ends are provided with the bearing seat installation place, the aperture of bearing seat installation place is greater than the aperture at roller middle part, bearing seat is made of bearing seat metallic core and bearing seat plastic body, this bearing seat metallic core is located at bearing seat plastic body inside by injection moulding, and the bearing seat plastic body outside is sentenced the interference mode with the bearing installation at roller two ends and is connected.
Described bearing seat plastic body is made of polyvinylchloride, and roller is made of polyvinylchloride.
Described bearing seat plastic body is connected by welding manner with roller.
The reinforced rib quantity of roller inwall is 10, and these 10 reinforced ribs evenly are provided with along the roller circumferencial direction.
Be axially arranged with 10 auxiliary holes along it in the bearing seat plastic body, these 10 auxiliary holes evenly are provided with along bearing seat plastic body circumferencial direction.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with along its axial reinforced rib at non-metal carrying roller 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 roller and the bearing seat body that adopt polyvinylchloride to constitute, the two is an interference fit, be injected with metal shaft bearing core body in the polyvinylchloride bearing seat body so that bearing is installed and axle, the manufacturing process of whole bearing seat is simple, guaranteed the mechanical characteristics of bearing seat simultaneously, and the bearing seat of polyvinylchloride is connected easilier with the interference fit of roller, can guarantee the right alignment of roller and bearing seat, improves the rotproofness and the service life of carrying roller.Under cylinder and bearing seat body interference bonded assembly situation, if adopt welding manner to connect between roller and the bearing seat body, can reduce welding heat stress to connecting the influence of precision, strengthen roller and bearing seat Joint strenght, guarantee the right alignment of carrying roller, prolong the service life of carrying roller.At the roller inwall reinforced rib is set evenly, can make roller intensity even, further reduce the weight of roller wall thickness and cylinder, on bearing seat, evenly offer auxiliary hole simultaneously, under the situation that does not influence bearing seat intensity, alleviate the weight of bearing seat, and then reduce the weight of carrying roller.
