    摘要: A crankshaft in which vibrations can be damped effectively without changing a design of a crankcase. The crankshaft comprises a first crank section located at one end of the crankshaft, and a second crank section located at the other end of the crankshaft. In the first crank section, a mass of a first inner balance weight is greater than a mass of a first outer balance weight. In the second crank section, a mass of a second inner balance weight is greater than a mass of a second outer balance weight.

    摘要: A transmission device for a power-driven cutting tool includes a base, a transmission component, a linking component, a shaft component and a link component. The base has a through cavity, a sleeve and a receiving portion. The transmission component is penetratingly disposed in the through cavity, so as to couple the transmission component and the base together. The linking component is penetratingly disposed in the sleeve, so as to couple the linking component and the base together. The shaft component and the link component are disposed in the base. A power source drives the linking component and thereby sequentially drives the shaft component, link component, and transmission component, allowing a cutter of the power-driven cutting tool to undergo reciprocating displacements along a linear path for performing a cutting operation. The transmission device features enhanced structural rigidity, allowing the cutter to move back and forth along a linear track.

    摘要: A variable stator vane arrangement includes a casing, a plurality of stator vanes, at least one control ring, a plurality of connecting rods and a crankshaft. The stator vanes are circumferentially spaced apart in the casing and the plurality of stator vanes are rotatably mounted in the casing. Each control ring is rotatably mounted on the casing and each stator vane is connected to an associated control ring. The crankshaft, rotatably mounted on the casing, is drivingly connected to each control ring and has an axis and a plurality of clevizes. Each connecting rod connects one of the clevizes on the crankshaft to a respective one of the control rings. At least one clevis is adjustably secured to the crankshaft by an adjusting mechanism and the adjusting mechanism is used to select the radial and/or angular position of at least one clevis relative to the axis of the crankshaft.

    摘要: The elements of an axially-aligning, eccentrically-adjustable, three-ring anti-friction roller bearing are arranged to compensate for inevitable small deformation and bore alignment errors for the journals of blanket cylinders of printing presses. Rows of rolling elements are disposed between the three bearing rings, the outer one of which has an arcuating curved swing surface. For the purposes of increasing the radial rigidity of the anti-friction mounting and for taking radial forces, the roller bearing rows include cylindrical roller bearings. In addition, there are provided, at least at one axial end, ball bearings or cross-roller axial bearings to resist axial forces. The three bearings rings are braced relative to one another axially and/or radially by a lock nut or the like threaded on the journal for urging the inner bearing ring against the bias of a spring engaging a shoulder on the journal on the other side of the bearing.

    摘要: An engine crankshaft has a crankpin that is radially slidably mounted relative to the crankshaft axis so that its axis can follow other than a circular path centered on the cranking axis. The mechanism includes at least one main bearing section with a stationary eccentric bearing surface, and at least one web fixed to the crankshaft and extending radially from the main bearing section. A housing is slidably mounted on guide surfaces on the webs for a sliding movement along the web, and has a crankpin secured thereto. The non-rotating eccentric bearing surfaces engaged by the housing force the housing to slide radially in and out along the web in synchronism with rotation of the crankshaft such that the distance of the center of the crankpin axis from the center of the main bearing section axis varies as a function of the angle of rotation of the crankshaft.
