摘要： An engine chain or belt tensioning system includes a tensioner pivot arm with a ratcheting means that includes backlash in an engine timing system. The tensioner system includes a tensioner pivot arm having a fixed pin, ratchet teeth, and a connection for a rotation-causing device, all being spaced radially outward from a pivoting feature. The pivoting feature and the fixed pin are positioned between two strands of a chain. An arm carrying a shoe extended outside the strands of chain and positioned to contact an outside portion of chain is pivotally mounted to the fixed pin. Rotation of the pivot arm causes the arm and shoe to draw inwards, imparting tension to the chain strand. The ratchet teeth allow free rotation of the tensioner arm in one direction, but not the other.

摘要： The invention is directed to a tensioner assembly for providing tensile force from a floating vessel at the surface of the ocean to the blowout preventer stack, or production tree, which is connected to the wellhead at the sea floor. The tensioner assembly compensates for vessel motion induced by wave action and heave and maintains a variable tension to the riser string alleviating the potential for compression and thus buckling or failure of the riser string. The tensioner assembly of the present invention includes a cylinder, a stop tube disposed with the cylinder, and a ram slidably engaged within the stop tube. The tensioner assembly also includes at least one gas, or air, transfer tube to create a pressurized air over hydraulic fluid arrangement to provide tensile force to the tensioner assembly.

摘要： A piston rod position detecting mechanism is proposed which can detect continuously or in a multiple-point manner that the piston rod position has changed due to increase or decrease in the protruding amount of the piston rod due to aging. The protruding amount from a cylinder end wall is detected by a position detecting mechanism comprising a detecting coil housed in a bobbin provided at the cylinder end, a flange portion formed on the piston rod, and a coil spring. Also, an autotensioner and an electromagnetic valve with such a position detector are proposed. Further, a belt tension adjusting device is provided with a detector for detecting the position of a tension pulley which is pivotable with increase or decrease in the belt tension.

摘要： To provide a hydraulic tensioner lifter which can reduce the filling time of oil pressure into an oil chamber which is in a state wherein air is present therein and can sufficiently exhibit a vibration-damping function. A hydraulic tensioner lifter for applying tension to an endless power transmission band of a power transmission mechanism includes a plunger fitted for sliding movement in an accommodation hole of a tensioner body B and cooperating with the tensioner body B to define an oil chamber therebetween. An air-bleeder mechanism is provided for exhausting air in the oil chamber to the outside of the oil chamber. The purge valve P has a check valve function of permitting the exhaustion of the air in the oil chamber to the outside of the oil chamber but blocking admission of air into the oil chamber from the outside of the oil chamber and blocking discharging of the oil pressure in the oil chamber to the outside of the oil chamber. In addition, the volume of oil in the oil chamber may be decreased by a spring guide portion which is accommodated in the inside of the tensioner spring for guiding the tensioner spring.

摘要： A blade-type tensioner for applying tension to a chain comprising a base, an arcuately shaped blade shoe having a chain sliding face, a spring provided on a back side of the blade shoe, and a guide member. The blade shoe has a proximal end portion and a distal end portion, where the proximal end portion is swingably supported on the base, and the distal end portion is slidably supported on a slide plate of the base. The slide plate is arcuately shaped to form a concavely arcuate arc face on an opposite side of the distal end portion of the blade shoe, and the distal end portion of the blade shoe has a convexly arcuate arc face corresponding to the concavely arcuate arc face of the slide plate. The distal end portion of the blade shoe is guided by a self-aligning action of the concavely arcuate arc face of the slide plate in such a way that the distal end portion is centrally positioned in a lateral direction on the slide plate. The guide member comprises a pair of guide portions formed integrally on opposite side edges of the distal end portion of the blade shoe, and hang below opposite side ends of the slide plate.

摘要： A tensioner lever for an engine timing chain comprises a synthetic resin lever body including a shoe having a chain-contacting sliding surface, and a spring-receiving portion on the back of a shoe. A laminated sheet spring is fitted into a slot formed in the spring-receiving portion along the longitudinal direction of the lever. The synthetic resin lever body is pivoted on a pivot shaft mounted on an engine, and an end of the laminated sheet spring is locked into a groove in the pivot shaft so that the spring can be stressed and thereby exert a tensioning force on the chain through the tensioner lever. The tensioner lever produces stable and quiet operation of the chain, and is more compact and less expensive than a conventional tensioner.
