The roller body includes idler wheel, wheel hub, wheel rim and former, and the roller body is idler wheel, wheel hub, wheel rim and former
Group weldering is constituted.
The end cap includes first end cover and second end cover, and the first end cover and the second end cover are respectively in idler wheel
Wheelboss inner hole two sides interference connection.
Elastic ring is provided on the wheelboss inner hole, the elastic ring connects with bearing lateral surface.
The bearing includes first bearing and second bearing, and first bearing and second bearing are mounted on the centre of roller shaft
At two side position of step.
It is provided with the lubricating cup hole in straight-through idler wheel axle center on one end face of the roller shaft, is provided at idler wheel axle center and lubricating cup
The radial through-hole of hole connection.
It is provided on one end face of roller shaft and penetrates through connection lubricating cup with lubricating cup hole.
The roller shaft both ends are provided with support, and the support and roller shaft clamping connect.
The support includes bottom plate and support plate, and the support is that bottom plate and support board group weldering are constituted.
The utility model provides a kind of roller devices on rolling-wheel fixed casting machine, the roller devices end cap with
Wheel hub takes interference fit, eliminates the screw attachment of the prior art, has saved the working hour of the threaded screw wire hole on wheel hub, has mentioned
High assembly effect, also facilitates the disassembly that user replaces bearing.Roller body and support are all made of welding fabrication, overcome forging
At high cost, casting is also easy to produce defect, and just all that has been achieved is spoiled for discovery after processing, and forging, casting exist by environmentally friendly restricted problem.
In addition, welding structure selects seamless steel pipe, steel plate, buying is convenient, and machining allowance is few, and comprehensive manufacturing cost is reduced than the prior art
40%, social benefit is good.
