20140057749 | CHAIN GUIDE - There is provided a chain guide capable of preventing a reduction in the durability of the chain guide. In the chain guide in which a base and a shoe are assembled together, a shoe protruding strip formed on a back surface of the shoe is engaged with a base groove that is formed in the base and continuously extends in a longitudinal direction so as to be movable in the longitudinal direction with respect to the base when the shoe expands or contracts, and be able to restrict the movement of the shoe in first and second width directions. | 02-27-2014 |
20140100068 | CHAIN TENSIONER - To provide a chain tensioner that has a simple structure, is universally usable and capable of supplying sufficient and necessary oil when restarted after a long time after the stop of oil supply, and enables reduction of its length and size. Urging unit | 04-10-2014 |
20140200104 | CHAIN TENSIONER - To provide a chain tensioner that has a simple structure, is universally usable, is capable of supplying sufficient and necessary oil when restarted after a long time after the stop of oil supply, enables reduction in entire length and size, and enables easy production and reduction in production cost. An urging unit | 07-17-2014 |
20140243132 | CHAIN GUIDE - There is provided a chain guide that reduces a space occupied by the chain guide in an engine room while maintaining required strength, rigidity, and durability with a simple configuration, reduces the number of manufacturing steps and the waste of a material, does not require a structure that permits an error, prevents increases in vibration and noise during use, and reduces the burden of a maintenance operation. The chain guide has a guide shoe and a base member that reinforces the guide shoe, and an attachment portion includes an attachment member that is provided separately from the guide shoe and the base member and can be fixed to at least one of the guide shoe and the base member or both of the guide shoe and the base member. | 08-28-2014 |
20140248983 | CHAIN GUIDE - The occupation space of a chain inside an engine room can be reduced, while the necessary strength, rigidity, and durability are maintained, the sheet thickness can be decreased, the number of production steps and material waste can be reduced, stress concentration and strains during bending and fixing can be reduced, load offset during fixing and loosening of bolts or the like can be prevented, the increase in vibrations and noise during the use can be prevented, the maintenance operation load can be reduced, and utility can be increased with a simple configuration. A chain guide is provided with a base member supporting a guide shoe. The base member has a base mounting portion and base wall portions formed to sandwich the guide shoe from both sides in a width direction. The guide shoe has a guide shoe mounting portion at a position apart from the base mounting portion in the chain running direction. | 09-04-2014 |
20140274514 | CHAIN GUIDE - A chain guide is provided in which durability is increased, weight can be reduced, material cost is reduced, the uniformity of resin orientation is improved, dimensional errors, errors in shape, internal strains, and defects are reduced, and bending rigidity such as rigidity against deflection and torsion is augmented with a simple configuration. The chain guide is provided with reinforcing ribs at a guide main body. The reinforcing ribs include first inclined reinforcing ribs and second inclined reinforcing ribs that cross each other. A zone in which the reinforcing ribs are not present is provided in the intermediate portion between two support porting. | 09-18-2014 |
20140323255 | CHAIN TRANSMISSION - A chain transmission is provided which is capable of reducing friction loss in the transmission of power without the risk of compromising the durability of a chain guide mechanism and the chain. The chain transmission includes a chain and a chain guide mechanism. The chain guide mechanism includes a first guide and a second guide having a smaller radius of curvature than that of the first guide. The plurality of plates include a first plate and a second plate. The first plate has a backside height set such that the first plate does not contact the first guide when the first plate is guided by the first guide and such that the first plate contacts the second guide when the first plate is guided by the second guide. | 10-30-2014 |
20150024889 | CHAIN GUIDE - The present invention provides a highly durable chain guide which is simply configured, easy to assemble, and low in material cost, and in which vibration and tilting are suppressed, enabling reductions in noise, wear, breakage, and so on. A guide shoe includes a plate housing portion which is formed on a rear surface side of a travel guiding portion, and into which a plate can be inserted from below, and in at least one location of an attachment portion or a tensioner contact portion, the plate housing portion constitutes a plate end holding portion formed to be capable of supporting an end portion of the plate from below such that the plate can be inserted therein from a direction other than from below. | 01-22-2015 |
20150045164 | CHAIN GUIDE MECHANISM - The chain guide mechanism includes a slack side guide, a tension side guide, and a link member that is capable of rotating about a predetermined rotary shaft provided so as to be fixed to an attachment subject. The link member includes a slack side pivot portion attached rotatably to the slack side guide, and the slack side pivot portion is disposed on an opposite side of the chain that is guided by the slack side guide to the predetermined rotary shaft, and in a lower position than the predetermined rotary shaft. The slack side guide is biased by its own weight toward a side of the chain that is guided by the slack side guide. | 02-12-2015 |
