Abstract
Disclosed is an oscillatingly driven machine tool including a tool spindle that is mounted pivotably about its longitudinal axis, further including a drive motor that is coupled to a hydraulic generator for generating an oscillating fluid flow which drives a hydraulic motor being configured as a rotor blade motor. The rotor blade motor drives the tool spindle in such a way that the tool spindle rotates oscillatingly about its longitudinal axis. The rotor blade motor includes symmetrically arranged rotor blades that are disposed at regular angular distances with respect to each other.
Claims20
An oscillatingly driven tool machine comprising:
- a tool spindle mounted pivotably about a longitudinal axis thereof;
- a drive motor driving a hydraulic generator for generating a pulsating fluid flow output at least at two output connections carrying pulsating fluid flows of alternating pressures;
- an oscillating hydraulic rotor blade motor comprising said tool spindle as a rotor;
- a plurality of rotor blades arranged on said tool spindle and forming fluid compartments together with a surrounding bushing, within which said tool spindle is supported rotatably;
- wherein at least one of said fluid compartments is connected with a first one of said output connections and at least another one is connected with a second one of said output connections, thereby moving said tool spindle oscillatingly back and forth about said longitudinal axis.
An oscillatingly driven tool machine comprising
- a tool spindle mounted pivotably about a longitudinal axis thereof;
- a drive motor being coupled with a hydraulic generator for generating an oscillating fluid flow;
- a hydraulic motor configured as a rotor blade motor comprising a plurality of symmetrically arranged fluid compartments being driven by said oscillating fluid flow, said hydraulic motor driving said tool spindle rotatingly oscillatingly about a longitudinal axis thereof.
An oscillatingly driven tool machine comprising a tool spindle mounted pivotably about its longitudinal axis, further comprising a drive motor being coupled with a hydraulic generator for generating an oscillating fluid flow for driving a hydraulic motor configured as a rotor blade motor for rotatingly oscillating driving said tool spindle about a longitudinal axis thereof.
