VIBRATION TRANSMISSION MEMBER AND WORKING MACHINE PROVIDED WITH SUCH A MEMBER

A transmission device comprises a hollow casing and a core member disposed in the casing. The core member is free to move in the casing in all directions. It has at least two arms to each of which a driving member or a driven member may be connected. The arms of the core member have a non-aligned an...

Beschreibung
Zusammenfassung:	A transmission device comprises a hollow casing and a core member disposed in the casing. The core member is free to move in the casing in all directions. It has at least two arms to each of which a driving member or a driven member may be connected. The arms of the core member have a non-aligned angular relationship to one another. The casing incorporates an internal housing whose configuration is a homothetic replica of that of the core member. There is clearance between the core member and the housing in all directions. At least part of each wall of the housing facing one of the arms of the core member is formed with at least one hole or recess which, by means of a network of internal conduits in the casing, can communicate with a source of pressurized supporting fluid. The transmission device is applicable to machine tools using ultrasonic, spark erosion and electrochemical machining processes.
