Abstract
A shearer-loader drive subassembly having a rotatably mounted drive sprocket, a transmission gear connected to the sprocket in a rotationally fixed manner, at least one releasable guide shoe provided for guiding the shearer loader on a rack arrangement, and a housing base plate, on which a bearing tube is supported and fastened in a rotationally fixed manner. The guide shoe is fastened by a pin which passes through the inner bore of the bearing tube and forms the pivot bearing for the guide shoe. A bearing sleeve rotatably supported on the bearing tube by a bearing may be arranged between the drive sprocket and the bearing tube, onto which bearing sleeve the drive sprocket may be pushed in a releasable manner.
Claims13
A shearer-loader drive subassembly, comprising:
- a rotatably-mounted drive sprocket for engaging in a rack arrangement adapted to propel the shearer-loader;
- a transmission gear arranged coaxially to a rotation axis of the drive sprocket and connected to the drive sprocket in a rotationally-fixed manner;
- at least one releasable guide shoe provided for guiding the shearer-loader on the rack arrangement;
- and
- a housing base plate on which a bearing tube arranged coaxially to the rotation axis of the drive socket is supported and fastened in a rotationally-fixed manner,
- wherein the guide shoe is fastened to the base plate by a releasable pin that passes through an inner bore of the bearing tube and forms a pivot bearing for the guide shoe.
A guide shoe for a shearer-loader drive subassembly, comprising:
- at least one base wall including a first through-opening adapted to accept and engage a pin;
- at least one opposing wall located opposite the at least one base wall and having a second through-opening adapted to accept and engage the pin;
- a guide extension formed on the at least one base wall, the guide extension adapted to engage underneath a rack arrangement and to releasably fasten the guide shoe to a base plate of the subassembly;
- and
- a subassembly-side bearing tube,
- wherein the pin is inserted into the subassembly-side bearing tube for the pivotable mounting and support of the guide shoe.
