BLOCK HEAD Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: block head striking end face is a surface formed by rotation of a shortened cycloid with parameter λ 0.3 to 0.5 around the block head longitudinal axis. The offered shape of the block head striking end face with a variable curvature provides for a more intensive growth of contact of the striking end face at its interaction with the waveguide. Due to it, the factor of transfer of kinetic energy to the waveguide increases, with the strike result remaining stable. EFFECT: enhanced effectiveness of transfer of kinetic energy to waveguide. 2 dwg
