1:8 tapered shaft. What does that mean?
(OP)
I have a motor with which the manufacture says that it has a 1:8 tapered shaft. I have to design a hub that goes on it. I know the diameter of the shaft before the taper, and I know the taper length. What I do not know is the angle of the taper or the diameter at the end of the taper. What does 1:8 taper mean?
Thanks
Thanks





RE: 1:8 tapered shaft. What does that mean?
1:8 taper mean the shaft diameter decreases by 1/8th the taper length.
Example:
Shaft diameter = 2.00
Taper length =3.5
Shaft has a 1:8 taper
The diameter at the end of the taper = 2-(3.5/8)= 1.5625
RE: 1:8 tapered shaft. What does that mean?
For every eight in length, you lose 1 in diameter.
A simple example, if your taper is over an 8mm length and your shaft is 10mm at the "thick" end, it will be 9mm at the other.
