Abstract
Official abstract text for this publication.
A spring retainer for a torsional vibration damper, including: first and second oppositely facing sides; at least one curved portion forming at least part of a radially outermost portion of the spring retainer and including: at least a portion of the first side enclosing at least one space and including at least one indentation extending in a circumferential direction; and at least a portion of the second side including at least one protrusion extending in the circumferential direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A spring retainer for a torsional vibration damper, comprising: first and second oppositely facing sides; a plurality of curved portions partially enclosing respective spaces and forming respective parts of a radially outermost portion of the spring retainer; and, for each curved portion in the plurality of curved portions: a respective portion of the first side partially enclosing the respective space and including a plurality of circumferentially disposed and radially aligned indentations; and, a respective portion of the second side including a respective plurality of circumferentially disposed and radially aligned protrusions, wherein: each indentation is aligned, in a direction orthogonal to the first or second side, with a respective protrusion. 2. The spring retainer of claim 1 , wherein said each curved portion is curved in a line orthogonal to an axis of rotation for the spring retainer. 3. The spring retainer of claim 1 , wherein each respective space is arranged to hold a respective spring. 4. The spring retainer of claim 1 , wherein: each plurality of circumferentially disposed and radially aligned indentations and the respective plurality of circumferentially disposed and radially aligned protrusions are each continuous in the circumferential direction. 5. The spring retainer of claim 1 , wherein said each curved portion is separated from remaining curved portions in the circumferential direction.
