| Summary: | The article shows the design features of tangential cams
with a rounded top, provides a method for determining
the lifting height and speed of the pusher when the
roller is rolling in a straight line and in contact with the
actual profile of the cam. The formulas for the kinematic
calculation of the tangential cam are refined taking into
account the radius of the initial circumference of the
shaft, the radius of the rounding of the cam tip and the
value of the radius of the pusher roller. Calculations are
given to determine the stroke and speed of the pusher
when the roller is rolling on the sections of the straight
and arc-shaped surface of tangential cams with a radius
of rounding of 6 and 10 mm. Formulas are proposed for
determining the lift of the pusher in the rolling section
of the roller along the radius of the cam tip at a constant
coefficient λ = 1 and λ = 1,5. Using the Mathcad program
calculations are performed and combined graphs of the
pusher lift and the change in its speed are constructed for
two types of tangential cams. |
