摘要： To provide a simple-structured chain drive mechanism that can reduce the noise generated when the chain sits on the sprocket, prevent deterioration of power transmission efficiency, and retard the progress of wear on the sprocket or chain. The chain drive mechanism includes a sprocket having a plurality of teeth, and a chain having a plurality of link plates and configured to be put around the sprocket. The sprocket includes a pair of flanges protruding circumferentially around the sprocket such as to sandwich the plurality of teeth from sides. The chain includes a pair of seat portions on both sides of the chain so that the flanges abut on the seat portions from a circumferential direction of the sprocket when the chain sits.

摘要： The invention is a silent chain with a profile capable of corresponding with the profiles of both sprockets and racks. The purpose of the invention is to convert rotational motion to linear motion in a way that is superior to the traditional rack and pinion device by allowing for more surface area contact with the rack through the use of, rather than a pinion, a silent chain that is capable of engaging with a rack. The invented silent chain comprises link plates of a particular shape stacked in alternating rows and joined together by connecting pins in such a way as to be bendable. The link plates are shaped such that the teeth of the link plates are offset when the chain is straightened, which allows the profile of the silent chain to correspond with the profiles of both sprockets and racks.

摘要： A hybrid vehicle is provided in which deterioration of vehicle mounting characteristics is suppressed. A drive device of the vehicle includes a power splitting mechanism having a sun gear to which a first motor-generator is linked, a carrier to which an output shaft is linked, and a ring gear to which an engine is linked, and a speed reduction mechanism that transmits the torque of the output shaft to a differential mechanism while reducing the rotational speed of the output shaft. The speed reduction mechanism is built up as a chain transmission mechanism which includes a driving sprocket that rotates together with the output shaft, a driven sprocket that is provided to the differential mechanism, and a belt chain that is fitted around these sprockets.

摘要： An inverted tooth chain assembly configured to mesh with a sprocket is provided including a link with an improved shape for increased strength. The link includes two teeth, a pair of outer flanks, first and second inner flanks, and a crotch located between the first and second inner flanks. A first transition point is arranged between the first inner flank and a first end region of the crotch, and a second transition point is arranged between the second inner flank and a second end region of the crotch. A crotch surface is defined between the first transition point and the second transition point and has a profile with a varying radius of curvature. The profile of the crotch surface has a smaller radius of curvature at the first and second end regions and a larger radius of curvature at a medial region between the first and second end regions.

摘要： An articulated chain includes alternate outer chain links and inner chain links interconnected by respective chain joints. The outer chain links comprise two outer link plates that are spaced apart in parallel, the outer link plates having two pin holes, which are spaced apart in the link-plate longitudinal direction and which each have fixedly arranged therein a respective joint pin of the chain joints. The inner chain links comprise two inner link plates that are spaced apart in parallel, and the joint pin being pivotably arranged in a joint opening of the inner chain links. The outer link plates comprise at least one expansion opening between the pin holes in order to reduce the bending of the joint pin and the surface pressure in the joint opening of the inner chain links, so as to improve the sliding behavior and the wear properties of the chain joints.

摘要： At least one member composing a chain bearing, e.g., a pin, includes a surface layer composed of vanadium carbonitride (VCN) coating on a surface of a base material of the one member. An oxide (VO) film having a predetermined thickness is also formed on a surface of the surface layer such that the oxide film is interposed between the surface layer and another member, e.g., a pin hole, composing the bearing. The VO film is suppressed from being formed excessively by the VCN coating even under a severe environment.

摘要： In a transmission chain, interleaved links are articulably connected by connecting pins, each connecting pin comprising two rocker pins arranged to roll on each other. Pin holes in each of at least two overlapping link plates in each interleaved pair of link plates are shaped so that each rocker pin moves with one of the overlapping link plates and is engageable with a bend-blocking surface in the pin hole in the other of the two overlapping link plates when the two overlapping link plates are in a straight part of the chain. The engagement of the rocker pins with the bend-blocking surfaces of the pin holes prevents the links from bending backward beyond their straight condition, i.e., in an outward direction, opposite to the inward direction in which the links bend relative to each other when engaging a sprocket.

摘要： In a transmission chain, guide plates are provided on opposite ends of guide rows. In a guide row, both of the guide plates can be contact guide plates arranged to contact sides of the transmission sprocket teeth. However, some of the guide rows are formed with one guide plate configured for contact with the sprocket teeth and the opposite guide plate configured so that it does not contact the sprocket teeth. The sprocket tooth-contacting plates can be on one side of the chain in some of the guide rows and on the opposite side of the chain in other guide rows. The guide plates in still other guide rows are configured so that they never contact the sides of the sprockets.
