At present several plans are adopted, one being to form the axle of mild steel, leaving it unhardened, the cones for forming the ball races being made of tool steel, hardened by quenching, which are either screwed on, the threads being left-and right-handed, or they may be sweated in place upon the axle. Stampings are also employed, which consist of cores of iron or mild steel, with outer shells of tool steel. A third method, and the cheapest, is to make the axle from one piece of special steel, which is to some extent hardened by quenching, and which should be also very thoroughly case-hardened. A very usual practice is to first turn up the axle roughly in an ordinary lathe, the portions forming the cones being left slightly in excess of the finished dimensions. The roughly turned axle is then subjected to the box-case hardening process, the parts required to be left soft being well plugged with clay, and the lid of the box tightly luted with a mixture of equal parts of clay and sand, and exposed in the furnace for from thirty to fifty hours. The materials used to pack round the articles in casehardening are usually small pieces of bone and wood charcoal, with some burnt leather. Cycle makers, however, unfortunately frequently prefer, for cheapness, to employ the prussiate of potash process, which only hardens the surface to a very slight depth. This is performed by first heating the axle to a bright red, rubbing the surface thoroughly with powdered prussiate of potash, or with a mixture of prussiate of potash 3, to salammoniac r, reduced to powder, allowing to cool to a dull red, and quenching in water. A repetition of the operation slightly deepens the hardening. The axle will after this hard...We have made it easy for you to find a PDF Ebooks without any digging.
