Hobbing force
NettetDuring hard rock excavation in the process of tunnel construction, the hard rock excavator wears seriously and quickly and reduces its excavation efficiency. Aiming at this problem, this paper proposes a composite rock breaking method by impact rolling and cutting as a solution. In this paper, the composite rock breaking characteristics of impact hob are … NettetThe machine constant for a hobbing machine can be found by installing all four change gears with the same number of teeth, and recording how many times the hob rotates relative to the gear blank. With the machine …
