Title:
LUBRICANT INJECTOR
Document Type and Number:
WIPO Patent Application WO/2015/133846
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a lubricant injector, which implements extrusion and pumping of a lubricant using a single power source, and which can intermittently perform extrusion of the lubricant, the lubricant injector comprising: a storage unit comprising a storage chamber filled with a lubricant, a piston provided inside the storage chamber, a screw shaft coupled to the piston so as to lift/lower the piston according to rotation, a following gear installed on the bottom portion of the screw shaft, and an elastic support member installed on one side of the screw shaft to elastically support the following gear; a power generation unit installed on one side of the lower portion of the storage unit to provide a rotation driving force; and an emission unit comprising a cylindrical cam which interworks with the power generation unit and thereby rotates, a driving gear which is formed on the top portion of the cylindrical cam and meshes with the following gear, thereby forming a space such that the lubricant is introduced into the cylindrical cam, a plunger which interworks with rotation of the cylindrical cam and moves up/down inside the cylindrical cam, thereby pumping the introduced lubricant, and an emission tube line formed inside the plunger such that the pumped lubricant can be emitted to target locations, wherein the following gear and the driving gear intermittently mesh with each other according to the change of pressure inside the storage chamber.
