Description

Support roller for belt conveyer

The utility model relates to the belt transporter carrying roller.

Belt transporter is widely used in the bulk material of industries such as metallurgy, chemical industry, power plant, building materials, harbour and the conveying of finished parts.Carrying roller is the main accessory of belt transporter, and per 0.8～1.2 meter skin band transport plane frame just need be equipped with 3 carrying rollers, and consumption is very big.

The belt transporter idler structure has two kinds at present, and a kind of is that bearing seat is a cast iron quality, and weight is big, accounts for 1/3 of carrying roller average weight, accounts for 18.6% of belt transporter weight, and is bigger to the foundation load influence; Another kind is the cold punching bearing seat, cooperates with the steel pipe roll body by the magnitude of interference, but easily loosening, this kind structure mostly is the transportation light-weight articles, and range of use is restricted.The carrying roller of two kinds of structures all exists owing to assembly parts cumulative errors reason, rotates dumbly, and rotational resistance is big, and oil pocket is little, about 20 grams of oleaginousness, bearing lubrication can not get guaranteeing that oil sealing easily comes off that anti-dust performance is poor, roll shaft and bearing are easily loosening, and roll shaft is shifted, so the carrying roller life-span is affected.

The purpose of this utility model is in order to overcome the problem of above-mentioned existence, design a kind of structural strength height, in light weight, rotate flexibly, play, oil pocket are not big for roll shaft, with rotate, lubricated, oil sealing holds and is the new construction carrying roller of one.

To achieve these goals, the utility model is by the following technical solutions:

The belt transporter carrying roller, comprise steel pipe roll body, bearing seat, bearing, roll shaft, it is characterized in that: bearing seat is contained in the end slot of steel pipe roll body and with the steel pipe roll body and welds, be sleeved in the bearing seat outward, bearing is contained in the bearing track of overcoat, and the cover spinning is buckled in and adjusts the outer multi-purpose cover that reaches location, stop, oil sealing purpose of interior cover on roll shaft in adjusting, dust protecting cap with nut and multi-purpose cover crimping is packed in the enclosing cover on the bearing seat.

Owing to adopt technique scheme, the utility model compared with the prior art, the structural strength height, in light weight, lubricated, dustproof, water resistance is good, improved carrying roller service life, alleviate foundation load, remarkable in economical benefits.

Accompanying drawing is belt transporter idler structure figure.

Embodiment in conjunction with the accompanying drawings further describes as follows:

The belt transporter carrying roller comprises steel pipe roll body 1, bearing seat 2, bearing 3, roll shaft 7, and the high-frequency straight seam welded pipe that the steel pipe roll body adopts solid drawn pipe or slices off inside and outside scar is made material, heavy partially, do not have oval.Bearing seat adopts the thick cold drawing compacting of 4mm to form, insert in the steel pipe roll body end slot and and weld with the steel pipe roll body, this bearing seat weight only is the 1/3-3/5 of the bearing seat weight of cast iron quality, overcoat 5 be contained in the bearing seat, bearing is contained in the bearing track of overcoat, inject the lithium based lubricating oil, cover 6 spinnings are on roll shaft in will adjusting, and adjust to the optimum position, be buckled in and overlap the outer location that reaches in adjusting, stop, the multi-purpose cover 4 of oil sealing purpose, with nut 8 dust protecting cap 11 with the multi-purpose cover crimping, in oil pocket, inject dustproof fat, be packed in enclosing cover 9 on the bearing seat with screw 10.Overcoat, multi-purpose cover, dust protecting cap, nut, roll shaft fuse in adjusting like this, and its roll shaft is inserted on the belt transportation machine support, are tumbler not, and steel pipe roll body, bearing seat, overcoat, bearing, enclosing cover, screw fuse, and are tumbler.

Claims (1)

1. The belt transporter carrying roller, comprise steel pipe roll body, bearing seat, bearing, roll shaft, it is characterized in that: bearing seat is contained in the end slot of steel pipe roll body and with the steel pipe roll body and welds, be sleeved in the bearing seat outward, bearing is contained in the bearing track of overcoat, and the cover spinning is buckled in and adjusts the outer multi-purpose cover that reaches location, stop, oil sealing purpose of interior cover on roll shaft in adjusting, dust protecting cap with nut and multi-purpose cover crimping is packed in the enclosing cover on the bearing seat.
