ABSTRACT

Length of the cylindrical section of the driven cone necessary to have a vertical motion of 0.5 in. for either of these designs may be calculated from equation (3-9). The results are that c=4.964 in. for the 40°, 50° combination and c=8.028 for the 45° pair. Thus, the 40°, 50° pair occupies a smaller volume, reduces the speed of the driven cone, may increase the torque to the driven cone, subject to the restrictions of the lining friction coefficient and the vertical force, and may have a smaller contact region between the cones. Conversely, the 45° pair occupies a larger volume, may give nearly a one-to-one speed ratio, and provides a larger contact area on a compressible lining between the cones.
