  • Rotation connection for connecting unaligned machine elements
    Patent number: 6264567
    Abstract: The invention concerns a machine arrangement with a first machine having a first rotation connection, a second machine having a second rotation connection, and a shaft for transmission of a torque, the shaft being unrotatably connected with both rotation connections. In this connection it is desired to minimize the effects of alignment errors on mounting the two motors. For this purpose the shaft (5) has, at least in one end, an external toothing (6) engaging with an internal toothing (8, 9) of the machine at this end, said external toothing permitting a swivel movement of the shaft (5), the teeth (10) of said external toothing (6) having concavely extending tooth flanks (11, 12), whose axial ends (15, 16) are less curved than their area of the axial centre.
