Abstract
A lubrication system for a roller chain. The lubrication system provides a lubricant reservoir, at least one piston pump, and synchronization means. The synchronization means has engaging means dedicated to mechanically mesh with roller chain in motion, and actuating means fastened in motion with the synchronization means the actuating means being in constant mechanical cooperation with a piston pump.
Claims17
A lubrication system for a roller chain that comprises:
- a lubricant reservoir;
- at least one piston pump having a piston body defining a piston cavity for the displacement of a piston, a piston body inlet connecting the piston cavity to the lubricant reservoir by an inlet pipeline, and a piston body outlet connecting the piston cavity to a lubricant applicator dedicated to supply lubricant to a portion of the roller chain;
- and
- synchronization means having engaging means dedicated to mechanically mesh with the roller chain in motion, and actuating means fastened in motion with the synchronization means, the actuating means being in constant mechanical cooperation with a portion of the piston of the piston pump, the piston being set in a back-and-forth motion in the cavity of piston pump by the actuating means,
- wherein the synchronization means comprises a pinion, the engaging means being formed by a plurality of radial teeth on an outer periphery of the pinion, each of the plurality of radial teeth, when viewed in cross-section, defining a flat surface.
