20110177899 | HYBRID BUSHED-SILENT CHAIN - A chain is disclosed having pins, each having a first end and a second end, and first and second outer plates press-fitted around the first and second ends of each of the pins, respectively. Each of the first and second outer plates has two pin holes through which the first and second ends of respective ones of the pins extend, respectively. First and second inner link assemblies, each consisting of at least one toothed inner plate, are disposed between the first and second outer plates. The at least one toothed inner plate has two openings each having a respective bushing press-fitted therein and arranged around respective ones of the pins with a slip-fit. Toothed middle plates, each having two pin holes press-fitted around respective ones of the pins, are disposed between the first and second inner link assemblies. | 07-21-2011 |
20110230289 | DOUBLE-SIDED INVERTED TOOTH CHAIN - The double-sided inverted tooth chain has inner link plates and middle link plates, which have teeth projecting in both a first direction and a second direction and a pair of pin holes. Also, the double-sided inverted tooth chain has outer link plates, which also contain pin holes, that are fixed to the inner link plates and the middle link plates by pins fitted into the pin holes of the link plates, forming an endless loop. | 09-22-2011 |
20110263366 | HYDRAULIC TENSIONER - A hydraulic tensioner for a traction element drive of an internal combustion engine, is provided having a tensioner housing with a hollow piston located in the housing bore. A check valve is located in the bore along a pressurized fluid path to the hollow piston, and a spring guide located in the housing in proximity to a base of the bore. A tensioning spring extends from the spring guide inside the hollow piston toward the piston head. A pressure relief valve is located within the hollow piston adjacent to the piston head, with the pressure relief valve including a valve body having a flange with a support surface that rests against an inside of the piston head and a hollow spring guide that extends from the flange toward the base of the bore. A valve seat is formed in the hollow spring guide, and a spring is located in the hollow spring guide and biases a valve ball against the valve seat. At least one of the support surface of the flange, the valve seat or the valve ball include surface indentations or irregularities that allow gas venting through the pressure relief valve. | 10-27-2011 |
20120317812 | RANDOMIZED CHAIN SPROCKET AND METHOD FOR MAKING A SPROCKET - A randomized chain sprocket has a set of four tooth gaps having three different tooth gap radial locations, two different link angles, and a chain with constant link pitch. | 12-20-2012 |
20140097563 | MECHANICAL TENSIONER STRUT WITH UNI-DIRECTIONAL FRICTION DAMPING - A strut including a housing, a plunger within a space in the housing and including a tapered outer circumferential surface, a primary spring engaged with the housing, a wedge element within the space and including a tapered inner circumferential surface engageable with the outer circumferential surface, and a secondary spring engaged with the wedge element and the plunger to urge the plunger in an axial direction. The primary spring urges the plunger in the axial direction with a first force. In a fully extended mode, the plunger is maximally displaced in the axial direction. In a contracted mode, the plunger is displaced in an opposite axial direction in response to application of a second force, sufficiently greater than the first force, on the plunger in the opposite axial direction. When the second force is sufficiently decreased, the plunger displaces with respect to the housing in the axial direction. | 04-10-2014 |
20150018150 | LAMINATED SPROCKET ASSEMBLY - A laminated sprocket assembly is provided formed of a plurality of layers that are connected together. Each of the layers is a stamped sheet metal layer having a plurality of spaced apart teeth located around a periphery thereof. The teeth in the plurality of connected layers are aligned. At least one of voids, channels, openings, or recesses are located in or between at least some of the layers for receiving and holding lubricating oil. This reduces noise and wear. | 01-15-2015 |
20150045163 | IDLER SPROCKET LUBRICATION ASSEMBLY AND METHOD - The invention presented is a chain drive sprocket assembly designed to capture lubricating oil from the engine sump or case and distribute the oil throughout the assembly including over the bearings. The invention provides a unique accumulator channel to capture dripping and splashing oil and exit ports with reduced pressure that enable the oil to be drawn through the bearing space and out the assembly, providing for continuous circulation of oil through the assembly. | 02-12-2015 |
