Turbine wheel for a gas powered medical handpiece

摘要

The wheel has blades extending in a radial direction from a hub and in an axial direction from a lateral ring land (29). Front side of the blades is curved concavely at a radial curvature axis. Rear side of the blades in an axial end region has an inclination surface (35), which is inclined to the front side in an axial direction and is inclined in a peripheral direction opposite to a rotational direction of the wheel. An independent claim is also included for a method for milling a front surface at a blade of a turbine wheel.
