Abstract
Systems and methods for mounting a timing belt pulley to a crankshaft can include a crankshaft rotatable about a center longitudinal axis, the crankshaft including a pin assembly configured for connection to a reciprocating piston. A timing belt pulley can be positioned against the pin assembly and configured for engaging the pin assembly such that the timing belt pulley is coupled to the crankshaft for rotation about the center longitudinal axis. For example, the pin assembly can include a slot formed on an exterior surface thereof, and the timing belt pulley can include a key extending towards the pin assembly and configured for engaging the slot.
Claims18
A drive system for an internal combustion engine comprising:
- a crankshaft rotatable about a center longitudinal axis, the crankshaft comprising a pin assembly configured for connection to a reciprocating piston, the pin assembly comprising a slot formed on an exterior surface thereof;
- and
- a timing belt pulley positioned against the pin assembly and comprising a key extending towards the pin assembly and configured for engaging the slot such that the timing belt pulley is coupled to the crankshaft for rotation about the center longitudinal axis.
A drive system for an internal combustion engine comprising:
- a crankshaft rotatable about a center longitudinal axis, the crankshaft comprising:
- a crank pin connected to the crankshaft and spaced radially from the center longitudinal axis and configured for connection to a reciprocating piston;
- and
- a counterweight connected to the crankshaft substantially opposing the crank pin, the counterweight comprising a slot formed on an exterior surface thereof;
- and
- a timing belt pulley mounted to the crankshaft for rotation about the center longitudinal axis, the timing belt pulley comprising a key extending towards the counterweight and configured for engaging the slot.
A method for mounting a timing belt pulley on a crankshaft of an internal combustion engine, the crankshaft comprising a pin assembly configured for connection to a reciprocating piston, the method comprising:
- positioning a timing belt pulley against the pin assembly;
- and
- aligning a slot formed on an exterior surface of the pin assembly with a key extending from the timing belt pulley towards the pin assembly;
- engaging the key on timing belt pulley with the slot in the pin assembly such that the timing belt pulley is coupled to the crankshaft for rotation about the center longitudinal axis.
