The subject of this invention is a device for directing the rack of a tieless feed gear to co-operation with the driving wheel of a mining machine. The guide shoe (1) is provided with an external slipper (6) and an internal slipper (7), whereby the distance between the slippers is approximately equal to the diameter of the pins (8) of the rack (3), and their height is approximately equal to the distance between the upper (11) and the lower (12) blade of the rack (3). The internal slipper (7) of the guide shoe (1) is mounted immediately to the body (15) of the traction machine (16) on both sides of the wheel (2). The external slipper (6) is mounted to the body (13) of the guide shoe (1), said body (13) being mounted to the body (15) of the traction machine (16) by means of pins (17). |
