Abstract
Official abstract text for this publication.
A laminated sprocket assembly is provided formed of a plurality of layers that are connected together. Each of the layers is a stamped sheet metal layer having a plurality of spaced apart teeth located around a periphery thereof. The teeth in the plurality of connected layers are aligned. At least one of voids, channels, openings, or recesses are located in or between at least some of the layers for receiving and holding lubricating oil. This reduces noise and wear.
First claim
Opening claim text (preview).
What is claimed is: 1. A laminated sprocket assembly, comprising: a plurality of layers that are connected together, each of the layers being a stamped sheet metal layer having a plurality of spaced apart teeth located around a periphery thereof, and the teeth in the plurality of connected layers are aligned and in flat planar contact with each other around the periphery; and recesses located in or between at least some of the layers for receiving lubricating oil, and the recesses are located on flanks of the teeth. 2. The laminated sprocket assembly of claim 1 , wherein each of the layers includes a shaft opening. 3. The laminated sprocket assembly of claim 2 , wherein aligned openings are defined in each of the layers in a position spaced apart from the shaft opening and the teeth. 4. The laminated sprocket assembly of claim 1 , wherein the recesses are located in at least some of the layers in sides of at least some of the teeth. 5. A laminated sprocket assembly, comprising: a plurality of layers that are connected together, each of the layers being a stamped sheet metal layer having a plurality of spaced apart teeth located around a periphery thereof, and the teeth in the plurality of connected layers are aligned; and recesses located in or between at least some of the layers for receiving lubricating oil, the recesses are located in at least some of the layers in sides of at least some of the teeth, and the layers on either side of the layers with the recesses include teeth having side flanks without the recesses. 6. The laminated sprocket assembly of claim 5 , wherein the recesses are formed by a radius. 7. The laminated sprocket assembly of claim 5 , wherein each of the layers includes a shaft opening. 8. The laminated sprocket assembly of claim 7 , wherein aligned openings are defined in each of the layers in a position spaced apart from the shaft opening and the teeth.
