摘要： To provide a chain tensioner capable of constantly providing an appropriate reaction force and damping characteristics for a variety of tension fluctuations irrespective of chain elongation, and capable of accommodating the tension fluctuations. The chain tensioner includes a distal end plunger 130 slidably inserted in a distal end bore 121 of a plunger 120, and a distal end biasing means 141 accommodated inside a second oil pressure chamber 102 such as to be able to expand and contract and to urge the distal end plunger 130. The chain tensioner further includes a check valve unit 150 that stops oil flowing from an oil pressure chamber 101 into the second oil pressure chamber 102, and a first relief valve unit 160 that releases oil toward the oil pressure chamber 101 when the pressure reaches or exceeds a predetermined high level.

摘要： A chain guide has an elastic member and a wear face. The wear face has the elastic member captured therein. The wear face has an inside surface and an outside surface. The first surface is disposed to contact a chain. The other surface is in contact with the elastic member. Through the compliance of the wear face and the elastic member, the chain guide absorbs some degree of impacts and transverse vibrations, both of which can affect chain control, guide wear, and bracket fatigue.

摘要： A chain and sprocket mechanism having a first sprocket, a second sprocket, and a chain engaged with the first and second sprockets, such that rotating the first sprocket moves the second sprocket via the chain. A tensioner is engaged with the chain between the first and second sprockets so as to apply tension to the chain. The tensioner is at least partly made of an elastic material, such as rubber or flexible plastic. The flexible material isolates the tensioner from vibrations, cushioning the tensioner and inhibiting the conduction of vibrations such as engine noise through the chain and the tensioner. The tensioner may be made partially or entirely of elastic material. The tensioner may be adjustable in a linear motion, to adjust the tension in the chain. The tensioning mechanism may be made so as to be mechanically simple, using translational motion only, without pivotal motion. The tensioning mechanism also may be functional without the use of springs or other elastic structures.

摘要： A crusher belt tensioning apparatus is arranged for being mounting on a crusher having a driven crusher pulley to actuate a crusher, a drive pulley drivable by a power unit, a belt extending between the crusher pulley and the drive pulley to transfer drive from the power unit to the crusher, and a tension drum mounted on a tension arm for applying a tension force to the belt. The tension arm includes a first relatively short arm portion and a second relatively long arm portion connected to the first relatively short arm portion. The tension drum is movable by a hydraulic cylinder, attached to the relatively short arm portion, between a first belt tensioning operating position in which the tension drum applies tension to the belt and a second belt non-tensioning maintenance position in which the belt is removable from the tensioning apparatus.

摘要： A tensioner device, includes a housing defining a cylindrical bore. A plunger is disposed in the bore and has a non-cylindrical outer surface. A spring is engaged with the plunger for biasing the plunger in an outward direction and an oil passage is in communication with the cylindrical bore for delivering pressurized oil to the bore. The non-cylindrical outer surface provides hydraulic clearance areas between the plunger and the bore to provide improved damping without high damping force.

摘要： A tensioning and damping element for endless chain drives, especially for roller chain drives, can be used for endless chain drives, which are to be tensioned diametrically. The material is an elastic plastic. All told, the known tensioning and damping elements, in conjunction with the wear of the chain, the load changing phases, as well as the reversing according to the degree of deformation, have the disadvantage of a phased running irregularity, an increased running noise and of wear-intensive areas in the toothed rim. An element with a ring part and a toothed rim of arc-shaped teeth with, in each case, axially opposite bulges in the roller-seating and, between these, roller-seating depressions, grooves, which are disposed peripherally between the ring part and the bulges, an extended pitch and extended roller-seatings with the advantageous profile shape similar to a semielliptical curve lying on the root circle.

摘要： A blade tensioner includes a blade shoe having a chain slide face, a plurality of blade springs for applying spring force to the blade shoe, and a spacer member interposed between the adjacent blade springs. Each of the blade springs is in the shape of a leaf spring. The blade springs are positioned and layered on the opposite side of the blade shoe from the chain slide face. The spacer member preferably contacts the corresponding blade spring at two contact points apart from each other at a uniform distance. In the blade tensioner of this invention, the blade spring contacts the spacer member at a constant span, which causes the damping coefficient of the whole blade spring to be constant and also causes the damping performance of the blade tensioner to be stable.
