Oil delivery system for the lubrication of a chainsaw

A chainsaw having a fluid lubrication system, configured to lubricate an interface between a chain blade and a bar channel of a guide bar, comprising:

• the guide bar, comprising an elongated member with the bar channel located around a perimeter of the elongated member, wherein the chain blade is configured to interface with and ride along the bar channel of the guide bar, and wherein the bar channel is configured to guide the chain blade to rotate around the guide bar to saw through a material;
• a motor having a motor drive shaft that extends from the motor to spin a chain blade gear configured to drive the chain blade along the bar channel of the guide bar;
• a fluid reservoir;
• a fluid lubricant contained in the fluid reservoir;
• a gerotor pump, comprising:
• a pump housing, having a fluid inlet port and a fluid outlet port, wherein the fluid inlet port and the fluid outlet port are each connected to a system of fluid feed lines, and wherein the motor drive shaft extends from the motor further into the pump housing;
• an inner gerotor gear, having a number of gear teeth, wherein the inner gerotor gear is secured to the motor drive shaft, such that it will spin with the motor drive shaft;
• an outer gerotor gear, having a number of gear notches equal to the number of gear teeth plus an additional notch, such that for n gear teeth there are a total of n+1 gear notches, wherein the inner gerotor gear is positioned within the outer gerotor gear such that it transfers the spinning rotation of the motor drive shaft to the outer gerotor gear;
• one or more fluid pocket recesses formed by the pump housing and configured to create one or more dynamic fluid enclosures by spinning of the inner and outer gerotor gears, wherein the dynamic fluid enclosures are configured to receive the fluid lubricant as it travels from the fluid inlet port to the fluid outlet port, wherein the fluid lubricant provides lubrication between the inner and outer gerotor gears and the pump housing;
• a fluid-tight seal positioned around the inner and outer gerotor gears inside the pump housing;
• and
• the system of fluid feed lines, wherein the system of fluid feed lines establishes fluid communication between the fluid reservoir, the gerotor pump and a point of application within the bar channel, and wherein the gerotor pump is configured to pump the fluid lubricant from the fluid reservoir, through the system of fluid feed lines and to the point of application.
