Abstract:

This invention relates to horizontal eccentric driving gears such as are used in pumping plants, and particularly to a means for providing adequate lubrication for the same while preventing the scattering of lubricating oil.

In the usual construction at the present time there is nothing but a low lip around the periphery of the eccentric to prevent the lubricating oil from being thrown off by centrifugal force from the lower edge of the eccentric after passing down between the bearing surfaces. Any excess oil is thrown toward the portion of this lip furthest removed from the center of rotation and spills over the edge. It is difficult to regulate the supply of oil so that there will be sufficient to properly lubricate the bearing surfaces without having some spilling over the above mentioned lip.

According to the present invention the lip is extended upward to substantially the height of the bearing surfaces, and is preferably curved inward at' the top, thus forming a ring shaped cup of adequate proportions for catching the oil discharging from the lower edges of the bearing surfaces.

Most of the oil is thrown by centrifugal force to that portion of the cup furthest removed from the center of rotation of the eccentric, and forms there a relatively deep pool. In accordance with another feature of the invention I provide a pump having an intake terminating in this deep pool of oil and a delivery tube for supplying oil to the bearing surfaces. I am therefore able to supply the bearing surfaces with a continuous flow of oil and thereby obtain maximum efficiency of lubrication. The pump is conveniently operated by means of a cam surface on the eccentric ring, since the pump is secured to the eccentric and travels around the ring.

Claims:

1. In combination with a horizontal eccentric driving gear comprising an eccentric and an eccentric ring cooperating therewith and having a lip extending outwardly from the bottom of said eccentric and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said lip at the portion thereof-furthest removed from the center of rotation of the eccentric, and a delivery conduit for said pump communicating with the bearing surfaces of the eccentric and eccentric ring.

2. In combination with a horizontal eccentric driving gear, comprising an eccentric and an eccentric ring cooperating therewith, and having a lip extending outwardly from the bottom of said eccentric, and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said lip at the portion thereof furthest removed from the center of rotation, upward extensions on said eccentric and said eccentric ring forming an oil receiving well above their bearing surfaces, and a delivery conduit for said pump communicating with said well.

3. In combination with a horizontal eccentric driving gear comprising an eccentric and an eccentric ring cooperating therewith and having a lip extending outwardly from the bottom of said eccentric and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said ip at the portion thereof furthest removed from the center of rotation, upward extensions on said eccentric and said eccentric ring forming an oil receiving Well above their bearing surfaces, said eccentric also having a recess opening into said well, oil conduits extending from said recess downwardly along the bearing surfaces, and a delivery conduit for said pump opening into said recess.

4. In combination with a horizontal eccentric driving gear comprising an eccentric and an eccentric ring cooperating therewith and having a lip extending outwardly from the bottom of said eccentric and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said lip at the portion thereof furthest removed from the center of rotation of the eccentric, and a delivery conduit for said pump communicating with the bearing surfaces of the eccentric and eccentric ring, said eccentric ring having a plurality of radial holes for permitting oil to flow from the bearing surface into the space enclosed by said lip.

5. In combination with a horizontal eccentric driving gear comprising an eccentric and an eccentric ring cooperating therewith and having a lip extending outwardly from the bottom of said eccentric and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said lip at the portion thereof furthest removed from the center of rotation of the eccentric, a delivery conduit for said pump communicating with the bearing an oil pump mounted on said eccentric, a suction conduit for said ump opening into the space enclosed by said lip at the portion thereof furthest removed from the center of rotation of the eccentric, a delivery conduit for said pump communicating with the bearing surfaces of the eccentric and eccentric ring, a dust ledge on said eccentric ring projecting over the bearing surfaces, a cam surface on said. dust ledge, and pump operating means engaging said cam surface.

7. In combination with a horizontal eccentric driving gear comprising an eccentric and an eccentric ring cooperating therewith and having a lip extending outwardly from the bottom of said eccentric and then upwardly to substantially the height of said eccentric, an oil pump mounted on said eccentric, a suction conduit for said pump opening into the space enclosed by said lip at the portion thereof furthest removed from the center of rotation of the eccentric, a delivery conduit for said pump communicating with the bearing surfaces of the eccentric and eccentric ring, a dust ledge on said eccentric ring projecting over the bearing surfaces and then downward, the lower edge of said dust ledge being in the form of a cam, and pump operating means engaging said lower edge.
