| Abstract: | The causes of failure of currently used hammer stems as well as expe-riences reported abroad are discussed. The correct design idea that a slender hammer stem should be provided with its elastic support to lengthen the life expectancy of the stem is described. A complete calculating theory, including the applied force analysis, the calculation of load and dynamic displacement, the calculation of the rigidity and dimensions of the rubber spring and the calculating formula for stem stability and maximum, stress at the bumping end, is proposed. Permissible limits are given. Calculated results of a German-made type KGK250 pneumohydraulic hammer show that the design calculation proposed is feasible. |
