Reset moment free roller or disc drill head - has motor and drill on common mounting in direct drive contact

摘要

The reset moment-free roller or disc drill head has the motor (1) and drill (2) on a common mounting (3). The driven shaft (4) of the motor is coupled directly or indirectly to the drill. Additional drills (5) are located on the same mounting, which is coupled to a frame (7) by bearings (6). The frame holds all the aggregate (8) required for drilling and the link (9) for the movement for the drill head in the drill axis. USE/ADVANTAGE - Reduced gearing through direct drive.
