Abstract
A reinforcing plate (405) is utilized with a lightweight hub (101) in a vibration damper. Holes (105) formed in the hub (101) and the reinforcing plate (405) allow the vibration damper to be mounted to a shaft with a stronger joint than when the reinforcing plate (405) is not utilized, thereby preventing deformation of the hub (101). Optional reduction holes (111) formed in the hub (101) provide for additional weight reduction, vibration reduction, and/or noise reduction.
Claims1
An assembly for use with a shaft, the assembly comprising:
- a hub including a plurality of reduction holes formed in a wall of the hub and a guide in which a plurality of mounting holes and a dowel hole are formed in a fixed pattern;
- a damping element disposed on an outer perimeter of the hub;
- an inertia ring disposed on an outer perimeter of the clamping element;
- a reinforcing plate disposed on the hub, wherein a plurality of mounting holes and a dowel hole are formed in the fixed pattern in the reinforcing plate, such that threaded fasteners secure the reinforcing plate and the guide through the plurality of mounting holes in the reinforcing plate and through the plurality of mounting holes in the hub.
