Abstract: A power transmission chain belt wherein each of two mutually offset parallel chains includes connected sets of parallel links, and spaced-apart parallel load block members engage the inner side of the parallel chains. Each set of parallel links includes link plates each having a pair of gripping protrusions formed so as to extend from an inner-side end face facing the load block members. The protrusions engage a pair of engaging grooves formed on each load block member, to thereby hold the link plates. The grooves are open on the opposite end faces of the load block member, and are provided with stopper means for inhibiting relative movements of the link plates and the load block member.

Abstract: A power transmission chain belt wherein sets of parallel links each including at least inner link plates are connected by pivot members to form each of at least two chains arranged in side-by-side parallel relationship with each other with a relative longitudinal offset distance, each pivot member having a first pin and a second pin which rolls on the first pin and whose rotation is prevented. The first and second pins extend through at least the inner link plates, and one of the first and second pins extends, preferably, the second pin, also through an outer link plate of each chain. The chain belt incorporates a mechanism which is associated with the end portion of the above-indicated one of the first and second pins, for inhibiting longitudinal relative movement of the chains.

Abstract: A power transmission chain belt wherein each of two mutually offset parallel chains includes connected sets of parallel links, and each chain is associated at its inner side with spaced-apart parallel load block members. Each set of parallel links includes link plates each having gripping protrusions on its inner-side end face which includes a concave part which is located between the protrusions and which engages an outer-side end face of the load block member. The inner-side end face of each link plate has surface regions which are spaced or offset from the concave part, in a direction from the inner side toward the outer side of the chain belt.

Abstract: A continuous belt of a continuously variable transmission for transmitting a driving torque from an input pulley to an output pulley includes a plurality of blocks, links and pins. Each block includes first and second side engagement surfaces. When the continuous belt spans between the input and output pulleys, at least two different engagement points are defined between the blocks and the pulley. Each link includes first and second end portions, an intermediate portion, first and second connecting holes, an outer projection and an inner projection. The first and second connecting holes are defined within the first and second end portions. The outer projection projects from the first and end portion toward a lateral direction of the continuous belt. The inner projection projects from the first end portion in a direction opposite the direction of the outer projection. Each link has a pitch line of the link which passes through center points of the first and second connecting holes.

Abstract: A chain belt comprises a plurality of V-shape blocks and connecting means. The V-shape block includes a pair of lateral side surfaces, a first contacting surface and a second contacting surface. An opening is defined within the first and second contacting surfaces of the V-shape block. The connecting means connects the plurality of V-shape blocks to each other, and forms a continuous loop. The connecting means includes a plurality of links and a plurality of pins. The link is inserted in the opening of the V-shape block. The link includes a pair of ends and an intermediate portion. The intermediate portion of the link is positioned in the opening of the V-shape block. The ends of the link are located on opposite sides of the V-shape block. An aperture is defined within each of the ends of the link. An outer projection extends outwardly from at least one of the ends of the link toward the outside of the continuous loop.

Abstract: An endless belt for the power transmission, wherein a plurality of block bodies each comprising a body member formed of a highly rigid material and provided at opposite side portions thereof with inclined surfaces being in frictional engagement with pulleys and a clamp member formed separately of said body member are arranged in a row and adjacent to one another on a belt-shaped endless carrier formed of fabric in such a manner that the endless carrier is clamped between the body members and the clamp members, the endless belt being of such an arrangement that the belt-shaped endless carrier formed of fabric is woven by warps disposed in the longitudinal direction and wefts disposed in the widthwise direction, with the wefts restraining the warps.

Abstract: A V-belt assembly trained over V-belt wheels which includes a flexible endless belt, a plurality of rigid suspension members secured fixedly to the endless belt perpendicularly to the longitudinal direction of the endless belt and approximately U-shaped rigid transmission pieces pivotably supported by pivotal projections projecting sidewise from both sides of the respective suspension members and capable of engaging V-shaped grooves in the V-belt wheels. The central axis of the pivotal projections passes through the approximately central portion of the thickness of the endless belt. In the ends of both legs of the U-shaped transmission piece are formed grooves for receiving the pivotal projection of the suspension member, and lids for covering respectively these grooves are secured fixedly to the ends of the legs.

Abstract: A V-belt assembly trained over U-belt wheels for transmitting power and which includes a flexible endless belt, a plurality of rigid suspension members secured fixedly to the endless belt perpendicularly to the longitudinal direction of the endless belt and rigid transmission pieces surrounding the respective suspension members in the section perpendicular to the longitudinal direction of the endless belt, supported pivotal projections projecting sideways from both sides of the suspension members and capable of engaging V-shaped grooves in the V-belt wheels. This rigid transmission piece is shaped in the generally rectangular form constituted from two generally U-shaped pieces. At least one of the pivotal projections of the suspension member and holes in the transmission piece located approximately in the center of a space between the top surface and the bottom surface of the transmission piece fitted on the pivotal projections of the suspension member is coated with an antifriction material layer.
