摘要
The invention relates to a boring machine comprising a spindle (15) which is designed for rotationally driving a boring tool that is placed or can be placed on the spindle and which is paired together with rotational drive means that interact with a first drive motor (24) for rotational driving purposes and with adjustment drive means that interact with a second drive motor (26) for axially adjusting the spindle such that when the spindle is being rotated by the first drive motor, the spindle can be axially adjusted under the effect of the second drive motor. The rotational drive means have a rotational drive gear (38) which is connected to the spindle, and the adjustment drive means have an adjustment nut (58) which interacts with a threaded section (60) of the spindle (15) in the manner of a slide. Transmission means are integrated in the form of a transmission module for interacting with the rotational drive gear and the adjustment nut and are designed to connect to the first and the second drive motor. The transmission means have an adjustment gear (54) for meshing into a toothing of the adjustment nut (58), said adjustment gear being driven by a toothed gear assembly (46, 42) which engages onto an outer toothing (52) of the adjustment gear such that at least one first toothed gear (42a-c) of the toothed gear assembly receives a drive torque of the second drive motor, in particular the at least one first toothed gear interacts directly with a drive shaft (30) of the second drive motor (24, 24A), and at least one second toothed gear (46a-c, 46′a-c) of the toothed gear assembly transmits a drive torque of the first toothed gear (26, 26k) to the outer toothing (52), in particular the at least one second toothed gear meshes directly with the first toothed gear and the outer toothing. The toothed gear assembly is held in a cage-like toothed gear support (44) such that at least the second toothed gear, preferably the first and the second toothed gear, can be released from the transmission module and replaced when disassembling the adjustment gear and/or a module which drives the rotational drive gear, in particular a toothed gear unit.
