TOOTH CLUTCH

The invention relates to a tooth coupling for high torque transmissions at high speeds with crowned teeth for radial and angular mobility.

The mobility of the coupling parts which are in meshing engagement with one another can be increased as desired transmitted torques and speeds are not too. So it was previously not possible to increase the speed over about 30,000 min "with a simultaneous power of about · 70,000 kW to increase further. Even the most careful lubrication and cooling conditions made no further possible Increase.

However, increasing the torque transmission at even higher speeds is required in many areas of mechanical engineering. The invention is therefore based on the object of designing a clutch of the type mentioned at the outset in such a way that the desired increases in the torques to be transmitted and the speeds are possible. To achieve this goal, the invention proposes to grind the tooth flanks of both the external and the internal gearing. Through the in the coupling

lungsbau unusual measure of use completely ground gears could surprisingly a considerable increase in the values for torque transmission and the speeds are achieved. For a further advantageous embodiment of the subject matter of the invention, it is proposed that crowning ratio

bation radius and r "indicate the pitch circle radius.

Immediate advantages of the invention are lower restoring forces, which are to be taken up by the bearings of the connected machines. The contact area of the toothing is considerably improved and a smooth run is achieved even in the partial load range. The flexibility of the coupling ' under load is optimal. Overall, the performance throughput is significantly increased with a low weight. So can for example torques of 1,400 Nm at 40,000 rpm " or 250,000 Nm at up to 9,000 rpm. With regard to the inventive measures taken "This sudden improvement can be described as surprising and unforeseeable.
