A STRIKER MEMBER, AND A DRILLING MACHINE COMPRISING A STRIKER MEMBER |
摘要 |
A circular cylindrical striker member 2 for a drilling machine adapted to transfer kinetic energy to an impulse receiving member 4. The striker member has a diameter dmax, and includes a side surface 12 and an impulse surface (6). The striker member is adapted to transfer the kinetic energy to the impulse receiving member by a ring shaped active surface of the impulse surface, wherein the ring shaped active surface is concentric with regard to the cross section of the striker member, has a diameter dawhere da<dmax, and has a width wa that during the contact moment with the impulse receiving pan is less than 0.2dmax. |
