摘要： The present invention describes a process to make enhanced fatigue strength micro-alloy steel. In the process of the present invention, the soaking temperature is maintained in the range of 900° C. to 1050° C. and soaking time in the range of 30-60 minutes depending on size of crankshaft to get refined grain size. Distortion of the components is prevented from occurring with provision of adequate supports especially designed for the process. Forged parts made using the process, such as crankshafts, have a refined grain pattern and result into 20 to 25% enhancement in torsion fatigue strength & 10-25% enhancement in bending fatigue strength. The present invention thus provides an enhanced ratio of the strength to material density and a micro-alloy whose torsion fatigue strength and bending fatigue strength are greater than the currently available micro-alloy steels.

摘要： A rotation drive device includes a crankshaft which has two ends dynamically connected to a drive source and a driven device, respectively. The drive source drives the crankshaft to rotate the driven device. The crankshaft structurally changes to make the two ends of the shaft portion connected to the rotation drive portion and the driven portion, respectively, at different central angles, which divides the space into two subspaces which are located two sides of the shaft portion, so that the wire can be arranged in the subspaces at both sides of the shaft portion, thus enhancing the flexibility of wire distribution while improving rotation range of motion.

摘要： An engine comprises a crankcase and a crankshaft. The crankshaft has a central main portion, a crankpin and a crankshaft web. A crank member is rotatably and eccentrically mounted on the crankpin. An external crank member gear meshes with an external drive shaft gear. A driven portion of the drive shaft is located at a side of the crankshaft web which is opposite to its side where the crankpin is located and is drivably coupled via a first transmission to an intermediate member which is rotatably mounted to the crankshaft. The intermediate member is drivably coupled to a control shaft portion of a control shaft via a second transmission which control shaft portion is located at axial distance of the driven portion of the drive shaft and the control shaft is rotatable at a fixed rotational position with respect to the crankcase under operating conditions at fixed compression ratio.

摘要： A pendulum crankshaft for an internal combustion engine includes a pendulum crankshaft having pendulum crank cycloid inserts. The inserts may thus be formed from high graded hardened steel while the crankshaft may be formed from conventional iron. The pendulum crankshaft includes a crankshaft having pendulum-holding ears. A cycloid insert-receiving aperture is formed in each of said ears for receiving a cycloid insert. Each of the cycloid inserts has a cycloid path formed therethrough. The pendulum is movably attached to the ears by a rolling pin fitted through the cycloid paths of the ears and captured between the cycloid paths formed in each half of the pendulum. Each half of the pendulum includes recessed areas on which the cycloid paths are formed. A pin is provided between each cycloid insert and the ear into which it is inserted to restrict rotation of the cycloid insert with respect to the ear.
