Kinematically-driven slow delivery lubrication system

A lubrication system driven by a rotating shaft, the system comprising:

• a first circular member and a second circular member coaxially mounted on the rotating shaft for rotation with said rotating shaft, the first circular member being coupled and imparting rotation to a third circular member, the second circular member being coupled and imparting rotation to a fourth circular member;
• combined diameters of the first and third circular members being different than combined diameters of the second and fourth circular members;
• the third circular member-being pivotally coupled to a first rigid linkage, the first rigid linkage extending from the third circular member to a fifth circular member and being pivotally coupled to the fifth circular member, the fourth circular member being pivotally coupled to a second rigid linkage, the second rigid linkage pivotally coupling the fourth circular member to the first rigid linkage between the third and the fifth circular members;
• the fifth circular member being coaxially mounted to a pump shaft;
• wherein rotation of the third and fourth circular members imparts rotational movement to the fifth circular member and imparts axial movement to the fifth circular member and pump shaft, which in turn pumps lubricant.

A method for pumping lubricant slowly using a rotating shaft of a transport system, the method comprising:

• coaxially mounting a first circular member and a second circular member on the rotating shaft for rotation with the rotating shaft;
• providing coaxial third, fourth and fifth circular members and a pump shaft coaxially coupled to the fifth circular member;
• coupling the first circular member to the third circular member and the second circular member the fourth circular member for imparting rotation to the third and fourth circular members respectively;
• coupling the third circular member to the fifth circular member with a rigid first linkage;
• coupling the fourth circular member to the first rigid linkage with a second rigid linkage at a joint disposed between the third and fifth circular members;
• rotating the first and second circular members with the rotating shaft thereby rotating the third and fourth circular members, thereby rotating the fifth circular member and causing the fifth circular member and pump shaft to move axially, thereby pumping lubricant with the pump shaft.
