Abstract
A turbine-gear train system for driving an axial flow water pump which comprises a turbine assembly and a gear train assembly. Air at high pressure does work on the impulse turbine wheel. The torque so generated is transmitted to the sun gear assembly of a two-stage planetary reduction gear. The output torque is taken in the same direction of rotation as the input. The system is a low-noise, high-power, lightweight compact system and permits a reduction in the output power-to-weight ratio by a factor of five or more.
Claims6
An air turbine and gear train system comprising:
- a turbine assembly, adapted to receive relatively high pressure air, for converting said relatively high pressure air to relatively high speed rotary shaft motion output;
- a gear train assembly, for receiving said relatively high speed rotary shaft motion output from said turbine assembly and reducing said relatively high speed rotary shaft motion to relatively low speed, high power rotary motion as the output thereof;
- and
- interconnecting means for connecting said turbine assembly and said gear train assembly;
- a relatively stationary housing;
- an input shaft, rotatably mounted within said relatively stationary housing;
- a first plurality of preloaded anti-friction roller bearings supported said input shaft;
- a turbine wheel, centrally mounted on said input shaft whereby said relatively high pressure air imparts motion to said turbine wheel thereby producing torque;
- and
- means for transferring said torque from said turbine wheel to said input shaft.
