Abstract

See full text

A roller cutter unit is mountable at a cutting head of undercutting mining machines. The cutter unit includes an elongate mount shaft to position and support a cutter ring. The cutter ring is secured to the mount shaft via a bracket having a wedge segment configured to be wedged axially and radially between the cutter ring and the shaft. Accordingly, a mounting mechanism is provided to achieve a desired force transmission pathway from the cutter ring into the shaft so as to maximize the locking action of the cutter ring at the cutter unit.
