Abstract (en)
[origin: WO2021081399A1] A housing mount assembly for supporting a roller cutter is described. The housing mount assembly comprises a housing mount defining an outer surface for attaching to a housing and a profiled inner surface extending away from the outer surface, the profiled inner surface defining a channel extending in a longitudinal direction, and a seat support block extending away from the outer surface and defining a first seat support surface transverse to the channel, and a second seat support surface transverse to the first seat support surface. The housing mount assembly further comprises a removable seat mounted on the seat support surfaces and defining two transverse roller cutter shaft support surfaces whereby the removable seat and the seat support block together provide support for a roller cutter shaft.
