Abstract
An automatic lubricating oil feeding apparatus for automatically feeding lubricating oil at predetermined intervals to rotary driving parts of various kinds of machines where bearings are installed. The apparatus can easily conquer the resistance of tube passages of the machines and thus facilitate the lubricating oil feeding to the machines by forming a lubricating oil discharge structure having a mechanical type vertical suction pump structure. The apparatus can also remove the oil-separation phenomenon even if the apparatus is used for a long time by effecting a pumping operation for suction and discharge of the lubricating oil by the pressure of a flanger ascending and descending by a mechanical driving force, and thus not applying a high pressure to a lubricating oil pouch. The apparatus includes a top cover wherein the lubricating oil pouch is installed, and a main case fastened to the top cover and receiving therein a nipple secured to a shaft of a bearing and a pump for controlling extrusion of a fixed amount of the lubricating oil. The pump is placed between an exit of the lubricating oil pouch and the nipple, and suction and discharge of the lubricating oil is performed b…
