Abstract: PROBLEM TO BE SOLVED: To withstand high torque without generating damage. SOLUTION: A power transmission system is provided with a plurality of endless carriers 102 extended over the whole length of a chain, and a plurality of moving members 110, 120 arranged along the carriers 102. The load support member (first moving member) 110 out of the moving members has first shape, and the load nonsupport member (second moving member) 120 out of the moving members has second shape. The first shape is engaged with a sprocket tooth 132 to transmit power between the first shape and the sprocket tooth 132.

Abstract: PROBLEM TO BE SOLVED: To reduce friction resistance of a chain between itself and a chain guide or a tensioner, generate uniformly a load share along a link train, reduce a cost, and facilitate manufacture and assembly, in a silent chain. SOLUTION: Several link plates 170 in a low back part height, which is a height between a horizontal line connecting an opening hole center and the highest point on an outer side surface, and several link plates 180 in a high back part height are combined, to be arranged. During operation, since only the link plate 180 in a high back part height is slid on a chain guide or a tensioner, friction resistance between a chain and the chain guide or the tensioner can be reduced. A thickness t2 of the link plate 170 is larger than a thickness t1 of the link plate 180. In this way, rigidity of both the link plates 170, 180 is made roughly equal, a load share along a link train can be uniformly generated.

Abstract: PROBLEM TO BE SOLVED: To absorb torsional vibration from a rotary shaft, facilitate the manufacture and assembly, and improve the durability. SOLUTION: Crank sprockets (first sprocket) 3, 5 fixed on a hub (rotary shaft) 20, a balance sprocket (second sprocket) 2 which is arranged in close proximity to the crank sprockets 3, 5 along the hub 20 and is rotatably supported on the hub 20, and a flat torsional spring 15 which has a spiral shape, drives and connects the crank sprockets 3, 5 and the balance sprocket 2, and allows relative rotation limited between the hub 20 and the balance sprocket 2 are provided.

Abstract: PROBLEM TO BE SOLVED: To dissolve the problem of unbalance distribution of load between phased sprokets. SOLUTION: This system is provided with a crank shaft-sproket pair 102 in which mutual sproket teeth are offset, connected to a crank shaft 100, a first balance shaft-sproket pair 132 in which mutual sproket teeth are offset, arranged on a first balance shaft 122, a second balance shaft-sproket pair 134 arranged on a second balance shaft 124, and a balancer chain 120 drivingly connecting the balance shaft sprokets to the corresponding crank shaft sprokets. The sproket of one of the first and second balance shaft sproket pairs is connected to each balance shaft. The sproket of the other of the balance shaft sproket pairs is rotatably supported to the balance shaft.

Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic tensioner capable of maintaining the tensional force of each chain in a tensioner system to control two lines of chains and reducing a cost. SOLUTION: A hydraulic tensioner 11 is composed of a housing 25 having a hole 23; a piston 50 slidablby in the hoe 23; a spring 53 to energize the piston 50 in the projecting direction from the hole 23: a valve 10 to allow the flow of a fluid from a pressurized fluid source into a chamber 22, and to block the floe of the fluid in the reverse direction practically; a flow passage 24 formed in the housing 25 to connect the chamber 22 to pressurized fluid source; and an arm with fulcrum to maintain the contact condition of the end of the piston 50 with a pair of chain guide arms. And, the piston 50 is moved to the outer side from the hole 23 by the flow of the fluid into the chamber 22.

Abstract: PROBLEM TO BE SOLVED: To facilitate manufacture and assembly. SOLUTION: First and second sprockets 22 and 24 are arranged on a central shaft 30. The outer sprocket tooth 36 of the first sprocket 22 is offset on a periphery from the outer sprocket tooth 38 of the second sprocket 24 by a given offset amount. The inner peripheral surface of the first sprocket 22 has substantially the same diameter and shape as those of the inner peripheral surface of the second sprocket 24, and the outer peripheral surface of the first sprocket 22 has the substantially the same diameter and shape as those of the outer peripheral surface of the second sprocket 24.

Abstract: A rocker joint for a power transmission chain (10) is formed from a single pin (20) and an associated link aperture (22, 24). The pin (20) has a substantially flat front surface (94) and a convex back surface (96), with the back surface being defined by a plurality of radii (98, 102, 104). The pin (20) is received in the aperture (22, 24) of the link (18) such that the front surface (94) of the pin (20) engages and rocks on the curved surface (69) of the link aperture (22, 24). The back surface (96) of the pin (20) is movable in the aperture (22, 24) of the links (18) as the surfaces move relative to one another when the chain (10) articulates.

Abstract: A chain and chain sprocket wheel system comprises a number of chains and out-of-phase or offset chain sprocket wheels. The power transmission system comprises a chain or a hybrid chain of arbitrary design with the offset chain sprocket wheels. The control system may have a single overhead camshaft or two overhead camshafts, the crankshaft chain sprocket wheels and the camshaft chain sprocket wheels being out of phase.

Abstract: The chain (10) comprises several parts of which a first part has sets of the same plates with a first profile and other sets with plates of a different profile. The individual parts of the chain wheel has several spaced teeth for interacting with the toothed plates of the chain parts. The position of the teeth of the second chain wheel part is off- set relative to the position of the teeth of the first chain wheel part. USE/ADVANTAGE - Sound-proofed chain drive for torque converters and vehicle parts in which offset phased relation between teeth reduces noise of knocks and vibrations.
