Abstract
A turbine blade indexing assembly adapted for variably adjusting the pitch of the turbine blades in a turbine wheel. The indexing assembly includes a housing secured to a turbine hub and an indexing ring contained between the housing and the hub and adapted for limited rotational movement relative to the housing. A plurality of radial bores are formed around the periphery of the housing and each bore is adapted to receive a cylindrical shank of the turbine blade therethrough. A blade retainer ring, having a transverse bore adapted to register with a transverse bore formed through the turbine blade shank, is positioned on each turbine blade shank so that a pin member inserted through the registering bores in the shank and retainer ring rotatably secures the turbine blade to the housing. One end of the pin member is received in an actuator slot formed in the indexing ring so that rotational movement of the indexing ring produces a corresponding axial rotation of the turbine blades. At least one bolt is provided to secure the indexing ring to the housing in order to prevent further rotational movement of the indexing ring relative to the housing after the proper turbine blade pitch is obtained.
