Abstract
The present disclosure provides a pulley, comprising a cylindrical wall having an outer surface with a plurality of circumferential grooves configured to receive a corresponding plurality of ribs on an inner surface of an elastic belt, a web connected to an inner surface of the cylindrical wall, a central hub connected to the web, the central hub comprises a central opening sized to be press-fit onto a drive shaft, and a drive feature configured to mate with a drive tool, thereby facilitating rotation of the pulley using the drive tool.
Claims14
A pulley, comprising:
- a cylindrical wall having an outer surface with a plurality of circumferential grooves configured to receive a corresponding plurality of ribs on an inner surface of an elastic belt;
- a web connected to an inner surface of the cylindrical wall;
- a central hub connected to the web, the central hub comprises a central opening sized to be press-fit onto a drive shaft;
- and
- a drive feature configured to mate with a drive tool, thereby facilitating rotation of the pulley using the drive tool;
- wherein the web comprises at least one opening adjacent the inner surface of the cylindrical wall, the opening being sized to receive a device for use in installation of the elastic belt onto the pulley.
3 more elements
An engine, comprising:
- a crankshaft;
- a plurality of components driven by rotation of the crankshaft, each of the plurality of components comprising a pulley coupled to rotatable element;
- and
- an elastic belt coupled to the pulleys of the plurality of components;
- wherein at least one component of the plurality of components comprises a press-fit pulley that is press-fit onto a drive shaft of the rotatable element of the at least one component, the press-fit pulley comprising
- a cylindrical wall having an outer surface with a plurality of circumferential grooves configured to receive a corresponding plurality of ribs on an inner surface of the elastic belt, and
- a central hub connected to the cylindrical wall, the central hub comprising a central opening sized to be press-fit onto the drive shaft, and a drive feature configured to mate with a drive tool, thereby facilitating rotation of the pulley using the drive tool to couple the elastic belt to the press-fit pulley;
- wherein the pulley comprises at least one opening adjacent the plurality of circumferential grooves, the opening being configured to receive a device for use in installation of the elastic belt onto the pulley.
