Load zone lubricant path for a cam roller pin

A cam roller pin rotationally fixed and defining a pin axis around which a cam roller is configured to rotate and apply a load at a load zone at a radially outer and lower end of the pin, the pin comprising:

• a reservoir disposed at a radially outer and upper end of the pin configured to receive lubricant for lubrication of the cam roller rotating oil the pin;
• a plurality of first lubricant paths each extending radially inward from the reservoir;
• a plurality of second lubricant paths each extending from one of the plurality of first lubricant paths to one of a plurality of second lubricant path outlets;
• a plurality of third lubricant paths each extending from one of the plurality of first lubricant paths to one of a plurality of third lubricant path outlets;
• and
• a plurality of load zone lubricant paths each extending from one of a plurality of load zone lubricant path inlets at the load zone at the radially outer and lower end of the pin to at least one of the plurality of first lubricant paths, the plurality of second lubricant paths, and the plurality of third lubricant paths;
• wherein each of the plurality of first lubricant paths is axially spaced apart, each of the plurality of second lubricant paths is axially spaced apart, each of the plurality of third lubricant paths is axially spaced apart, and each of the plurality of load zone lubricant paths is axially spaced apart.

A cam follower assembly comprising:

• a housing;
• a pin fixed with the housing, defining a pin axis, and configured for reciprocal movement with the housing;
• a cam roller configured to rotate around the pin axis of the pin from engagement with a cam lobe at a lower end of the housing and apply a load to the pin at a load zone corresponding to the lower end of the housing;
• wherein the pin comprises:
• a reservoir disposed at a radially outer and upper end of the pin configured to receive lubricant for lubrication of the cam roller rotating on the pin;
• a first lubricant path extending radially inward from the reservoir;
• a second lubricant path extending from the first lubricant path to a second lubricant path outlet;
• a third lubricant path extending from the first lubricant path to a third lubricant path outlet;
• and
• a load zone lubricant path extending from a load zone lubricant path inlet at the load zone at the lower end of the housing to at least one of the first lubricant path, the second lubricant path, and the third lubricant path.
