Abstract
In a drift advancing machine cutting rolls are rotatably supported on a centrally arranged pivoted arm. Each cutting roll has a separate drive, each of which comprises a drive motor, a drive shaft and a driven shaft being driven via a bevel gear gearing. The drive shaft is a hollow shaft, within which is accommodated the second drive shaft.
Claims8
Driving arrangement for driving cutting rolls of a drift advancing machine comprising at least one cutting roll being subdivided in axial direction and being in engagement over at least part of its circumference with the material to be excavated and being movable over the drift face in transverse direction to its axis of rotation, characterized in that two separate cutting rolls are rotatably supported at both sides of a swivellable cantilever arm being, in particular, swivellable around a swivelling axis extending in parallel relation to the axis of rotation of the cutting rolls, that said both cutting rolls are connected with drive motors via separate drive means and that the drive motors are arranged in the cantilever arm carrying the cutting rolls, the drive motors being in meshing engagement via drive shafts extending in parallel relation one relative to the other and via bevel gears with driven shafts extending in parallel relation to the axis of rotation of the cutting rolls, and the drive shafts being coaxially arranged, with one drive shaft being hollow and surrounding the other drive shaft.
