Abstract
The invention broadly comprises a torque converter including: a core ring; a turbine blade connected to the ring and having a perimeter with a segment facing an outer surface of the ring and disposed proximate the outer surface; and joining material fixedly connecting less than the entirety of the segment to the outer surface. The segment is fixedly connected to reduce resonance in the turbine. In some aspects, the ring includes an inner surface oppositely disposed from the outer surface and an open path between the surfaces. The present invention broadly comprises a notched turbine blade and a core ring with a discontinuity in an outer surface arranged to block capillary action for flowable joining material disposed in an interface between a turbine blade installed on the ring and the outer surface. The invention also broadly comprises a method for controlling resonance of a turbine in a torque converter.
