A Study on Strength of Toothed Belt : 6th report, Behavior of Belt and Pulley Tooth at Incomplete Meshing Region

抄録

In this paper, the interference between belt tooth and pulley tooth at the incomplete meshing region of toothed belt drives is numerically calculated by using the analytical method mentioned in the 4th report, and the influence of the radius of the tip corner rounding and the pressure angle of belt and pulley tooth on the interference is discussed. Also, the authors discuss experimentally on the effect of the radius of the tip corner rounding of pulley tooth on the fatigue strength of L type polyurethane and polychloroprene rubber belt, and the displacement of the belt pitch line depending on the load and the frictional force acting on belt tooth at the incomplete meshing region. Further, the sliding velocity of the contacting point of belt tooth and pulley tooth is calculated and the total nominal stress at the bottom land corner of belt tooth is discussed.
