Differing Materials
Hi, Hope you can help, I am the new research and development engineering student, working for CI logistics. I am in the process of designing a large screw to drive their most popular conveyor system. I am looking for an alternative material to make this screw out of as my first choice of EN8 steel will cost too much to manufacture. Are there any other materials that I should consider looking further into that could be used instead of steel? The size I am looking at is a diameter of 200mmx 600mm to be machined, the screw will have to be able to take a torque of approx 100Nm. The screw will drive a conveyor chain by the bearings which are sintered steel of hardness 58-60 on the C scale of the Rockwell hardness scale. Therefore the material will need to be able to withstand hundreds of hours of sliding with this steel. Can anyone give me any further information on what materials may be suitable, it will be gratefully received. Thanks Mark |
