HAMMER FOR PERCUSSION MECHANISM Russian patent published in 2004 - IPC

FIELD: machinery building, mining industry and building, particularly hammers.

SUBSTANCE: hammer has cylindrical piston part, cylindrical percussion part and cavity filled with material having specific weight different from that of main hammer material. Cavity has the shape of body of revolution. Radius of inner hammer cavity periphery in cross-section in any cut elementary layer is determined from the following equation: where R is outer radius of cross section of main hammer material, ρ is reduced radius of hammer cross-section, λ is parameter indicating ratio of specific weights of main material and material located in hammer cavity.

EFFECT: provision of stable percussion mechanisms position into case, generation of smooth impulses having no steps.
