The angle on this is such that it will never lock. One of the most common ones are those that define Morse tapers. Unfortunately there are quite a few sets of standards. Naturally it then becomes essential that there are standards for the sizes of tapers. A better quality car, such as, a Singer Senior would use splines.)īecause of these features tapers are used extensively in engineering. ( I think the wheels on an Austin Seven are held on using tapers and keys. In some cases a taper pair might have a key to ensure one pair cannot rotate. On the other hand if the angle is large enough the tapers will never lock together. But this is only true if the angles of both tapers are the same.Ī second important property is that as the angle of a pair of tapers gets smaller then there is a tendency for the two tapers to lock together. This is that if a male taper fits into a female taper then the axis of the male taper will automatically line up with the axis of the female taper. Making flutes on a conical surface is covered at : Making flutes on a conical surface Mechanicalįrom a mechanical point of view, tapers have a very important property. Some tapers that are ornamental might also be fluted. Ornamental tapers are usually external only. On tapers where the ratio of width to length is high very small errors in the angle can be very significant. Though it might appear that the angle is not critical the diameter at the top of the column and the diameter at the bottom will only be right if the angle is right. An example of this is a taper used merely as an ornament, for example on a column. Even so some ornamental taper that do not appear to need to be accurate do in fact require far more accuracy than one might expect. In this case the angle of the taper is not critical.
They make the job look properly finished or they can just be convenient. They may be ornamental or they may have a mechanical function.
