摘要： A tool for fitting a belt into the groove of a pulley. The tool comprises a base plate having a first and a second face. The plate is flat or forms a part of a cylinder and the first face is concave. The tool also comprises first and second holding members that are substantially flat and parallel with each other. The holding members are spaced apart and extend from the first face of the base plate. If the base plate is flat, the holding members are perpendicular to the base plate. If the base plate is not flat, the holding members are perpendicular to the axis of the cylinder at least partially formed by the base plate. The tool also comprises a guide member extending from a second face of the plate opposite to the first face.

摘要： It is desired to improve the wear resistance of the valve seat of the check valve in a hydraulic tensioner. The hydraulic tensioner includes a cylinder having a hollow space filled with hydraulic oil. A plunger is slidably mounted in the cylinder. A pushrod is mounted in the hollow space so as to be axially movable together with the plunger with one end thereof protruding from the cylinder. A spring is mounted in the cylinder to bias the plunger and pushrod outwardly of the cylinder. The plunger is formed with a passage through which the pressure chamber and the reservoir chamber communicate with each other. The passage is formed with a valve seat. A check ball is arranged so as to be moved into and out of contact with the valve seat. The check ball is adapted to contact the valve seat when the pressure in the pressure chamber exceeds the pressure in the reservoir chamber, thereby closing the passage. The valve seat is formed of a steel for carburizing and has a surface carbon concentration of 0.55-0.75% to reduce deposition of carbides and to have a surface hardness at least equal to the check ball. This improves wear resistance of the valve seat and thus extends the life of the hydraulic tensioner.
摘要翻译：期望提高液压张紧器中止回阀的阀座的耐磨性。液压张紧器包括具有填充有液压油的中空空间的气缸。柱塞可滑动地安装在气缸中。推杆安装在中空空间中，以便与柱塞一起轴向移动，其一端从气缸突出。弹簧安装在气缸中以将柱塞偏压到气缸的外侧。柱塞形成有通道，压力室和储存室通过该通道彼此连通。通道形成有阀座。一个止回球被布置成与阀座移动和脱离接触。当压力室中的压力超过储存室中的压力时，止回球适于接触阀座，从而关闭通道。阀座由用于渗碳的钢形成，并且具有0.55-0.75％的表面碳浓度以减少碳化物的沉积并且具有至少等于止回球的表面硬度。这提高了阀座的耐磨性，延长了液压张紧器的使用寿命。

摘要： A belt installation tool having a substantially planar body having a circumferential surface and a roller. The roller radially projects from the body. An axis of rotation of the roller is disposed cooperatively with a belt urging member. The belt urging member projects from an outer flange. The roller urges a belt slightly radially outward from a pulley center. The belt urging member then urges the belt laterally to install the belt in a pulley groove. A second roller projecting radially from the body and having an axis of rotation parallel to the body is used to remove a belt from a pulley.

摘要： A belt tensioner for a power transmission belt may be provided that operates on an endless path and that utilizes asymmetric motion control. The belt tensioner may have an arm with a belt engaging section and a drum section, a support member for securing the tensioner relative to the belt, where the arm pivots on the support member, and a tension spring that urges the arm to pivot about the support member in a first direction and urges the belt engaging section against the belt with a force to tension the belt. The tensioner also may have a fluid filled chamber inside a portion of the drum section of the arm and a valve pivotally attached to the tensioner so that the valve extends across the fluid containing chamber.

摘要： A combination starter-generator system for use in a vehicle is provided. The vehicle has an internal combustion engine and a battery. The system includes a starter-generator electrically coupled to the battery to generate a current and to start the internal combustion engine. A drive mechanism connects the starter-generator machine and the internal combustion engine. The starter-generator machine generates the current by receiving a charging torque from one side of the drive mechanism and starts the internal combustion engine by imparting a starting torque to a different side of the drive mechanism. The charging torque or the starting torque is a greater torque. A passive tensioning system cooperates with the drive mechanism to tension the drive mechanism only at the side of the greater torque.

摘要： A lateral sensor positioned proximate to at least one of the edges of a conveyor belt continually monitors the position of the edge of the conveyor belt. If lateral movement is detected by the lateral sensor, an adjustment motor rotates to move an end of a non-drive pulley to adjust for the lateral movement. The lateral sensor can be a non-contacting inductive proximity sensor, a proportional sensor such as a linear variable displacement transducer or a linear potentiometer which determines if the edge of the conveyor belt has moved laterally by monitoring the resistance in the spring, or a Hall effect sensor.

摘要： The belt tension/drive for a pinch roller system of the present invention combines means for urging a plurality of pinch rollers toward a capstan roller with means for driving pinch rollers when a pinch roller is not in contact with the capstan roller. The capstan roller is surrounded by and aligned with a plurality of pinch rollers. A resilient belt disposed about the plurality of pinch rollers urges the pinch rollers toward the capstan roller and drives any pinch roller not in contact with the capstan roller, assuring that all pinch rollers maintain the same surface speed as the capstan roller.

摘要： In a chain tensioner having a plunger biased to protrude from a housing by a spring, a pair of wedge-shaped cams are received in tapered recesses in the end of the housing, cooperate with racks formed on opposite sides of the plunger, and are urged against oblique seats formed by the tapered recesses by a biasing spring. The cams and racks produce a ratcheting action maintaining chain tension by preventing retracting movement of the plunger. The cams and racks disperse the load imparted to the plunger by the chain, and reduce localized wear, allowing the housing to be made from a light weight material such as aluminum. Accuracy requirements associated with conventional pawl-type ratcheting tensioners are avoided.

摘要： To provide a hydraulic tensioner, which can prevent the bottoming out or over-stressing of a spring in an incorporated check valve, can reduce the contact surface pressure between a check ball and a retainer, and can reduce the production cost, a hydraulic tensioner comprises a check valve incorporated in the housing which causes oil to flow into a high pressure chamber to block the back flow of oil. The check valve comprises a ball seat, a check ball facing the ball seat, a spring, which biases the check ball against the ball seat and a retainer, which retains the spring and limits the movement of the check ball. The spring comprises a conical coil spring, and the surface of the retainer, which retains the conical coil spring and limits the movement of the check ball, is formed in a flat surface.

摘要： In a ratchet-type hydraulic tensioner for a chain transmission, having a plunger and a housing forming a high pressure oil chamber, an excess supply oil discharge passage is provided. The discharge passage communicates with an oil supply passage leading from an oil supply opening, which receives oil under pressure from a oil pump, to a hydraulic check valve mechanism in the housing, which delivers oil to the high pressure oil chamber. Excess oil is discharged to the exterior of the tensioner housing and directed toward the chain. Excessive chain tension is avoided, and smooth and reliable chain travel, and suppression of whistling sounds, are achieved.
