    摘要: A stepless speed change mechanism in a belt transmission device comprising a first belt passed through a groove in a drive pulley and a first groove in an intermediate pulley, and a second belt passed through a second groove in the intermediate pulley and a groove in a driven pulley for transmitting rotation from the drive pulley to the driven pulley via the intermediate pulley. The first groove and the second groove of the intermediate pulley have an axial width gradually decreasing radially inwardly of the pulley. A partition provided between and defining the first and second grooves of the intermediate pulley is movable axially of the pulley to thereby vary the pitch diameter of each of the first and second grooves and steplessly change the speed of rotation to be transmitted from the drive pulley to the driven pulley. The state of contact of the first belt with the first groove portion is adjusted to be different from the state of contact of the second belt with the second groove portion so that when the partition moves axially for the speed change, the axial component of the pushing force exerted on the partition by one of the first and second belts differs in magnitude from the axial component of the reaction force exerted on the partition by the other belt.

    摘要: A method of manufacturing an oil ring is disclosed. The oil ring includes an annular oil ring body having a pair of rail portions at its axially upper and lower portions and butt ends, and a coil expander assembled in the inner periphery of the oil ring body. A number of oil ring bodies and annular spacers having a smaller diameter than the oil ring bodies are stacked, and then aligned and retained using a jig such that an outer periphery of the oil ring bodies becomes a circle. The aligned oil ring bodies are rotated and a flat region that is substantially level with respect to the outer peripheral sliding surface of the plurality of oil ring bodies is formed. Curved regions extending on both sides of that flat region are formed using a buff or an elastic grindstone.
