ABSTRACT:
An oil ring guide system comprises a shaft mounted for rotation in either of two directions. Bearings support the shaft at two spaced-apart locations. Each bearing is formed with a pair of slots. A reservoir is mounted below each bearing. An oil ring is received in each of the four slots. Each oil ring is supported by and encircles the shaft and dips into the reservoir, whereby rotation of the shaft in either direction causes rotation of the oil rings in the same direction so that the oil rings carry oil from the reservoir into the bearing for lubrication thereof. Eight guide rods extend through the upper portion of the bearings. One pair of guide rods is displaced about the shaft axis 45.degree. in a clockwise direction from the vertical. The pair of guide rods associated with the other oil ring of the same bearing is displaced about the shaft axis 45.degree. counterclockwise from the vertical. The two pairs of guide rods associated with the other bearing are similarly displaced respectively clockwise and counterclockwise from the vertical. Thus the oil rings deliver equal amounts of oil regardless of the direction of shaft rotation. The guide rods reduce the friction between the oil rings and the bearing, thereby increasing the rotational speed of the oil rings for a given rotational speed of the shaft and increasing the amount of oil delivered to the bearings.
