Abstract:

It is shown that a common type of valve sealing results from the high contact stresses provided when a spherical shape is forced into a conical depression. This work is dedicated to determination of the coefficient of friction in the area of relatively high specific pressures upon contact between a sphere and a cone. In the experimental study performed, the sphere was replaced by a device with three legs extending at even intervals around a circle from a cylindrical center section. The ends of the legs were worked into a spherical shape with a radus of 50 mm replacement of the sphere with a rod model allowed the authors to study the planar problem. Author
