Abstract

Reliability of hydraulic hammers depends to a large extent on the strength and durability of their main components. This remark applies in particular to tools of hammers that are subjected to extremely high loads. Degradation of these tools usually occurs in a few characteristic areas, i.e. in the impact zone, retainer zone, tool shank zone and tool tip zone. The causes and mechanism of the most frequent damage in the tools are explained. The numerical simulations of stress distribution in the impact zone and retainer zone were performed. Then, the strength of these zones was estimated and on this basis the maximum permissible impact velocity was determined.
