Abstract
The disclosed invention is a novel method for constructing a Torsional Vibration Damper (TVD). The traditional means used to construct the hub of the TVD was to employ a single material. The disclosed invention essentially discretizes the construction of the TVD hub into three regions: nose, spokes, and flange, and simultaneously aligns unique materials and manufacturing methods for each region with the structural loads borne thereby. Consequently, the invention helps in reduces four unwanted characteristics: (1) mass; (2) polar mass moment of inertia; and (3) casting scrap; and (4) cost. Furthermore, because of this construction other enhancements to the axial and angular structural integrity of the TVD can be reaped in certain cases.
Claims5
A Torsional Vibration Damper (TVD) comprising of:
- a hub, further comprising of:
- a nose further comprising of:
- a first annular surface oriented perpendicular to the central axis of the hub;
- a second annular surface opposing the first annular surface;
- bounded by a first axis-symmetric surface radially proximate to the central axis of the hub;
- and
- a second axis-symmetric surface radially distal to the central axis of the hub, further comprising of:
- a plurality of radially oriented blind holes;
- a flange further comprising of:
- a first annular surface oriented perpendicular to the central axis of the hub;
- a second annular surface opposing the first annular surface;
- bounded by a first axis-symmetric surface radially proximate to the central axis of the hub;
- and
- a second axis-symmetric surface radially distal to the central axis of the hub further comprising of:
- a plurality of radially oriented counter-bored or counter-sunk openings;
- a plurality of radially oriented solid monolithic fasteners each further comprising of:
- a cylindrical or conical head received by one of the counter-bored or counter-sunk openings in the flange respectively;
- and a cylindrical body attached to the cylindrical or conical head on one axial periphery and received by one of the blind holes in the nose on the opposing axial periphery;
- and
- an inertia member concentric about the hub with an elastomeric member operatively positioned therebetween.
