摘要： An automatic tension adjusting mechanism for a winding and transmitting device for an automatic door includes a base fixed in a casing; a mount for a transmission wheel around which a belt is wound; the mount being disposed on the base slidably in the right and left directions where the mount forces the belt to be strained and relaxed, and being resiliently energized at all times in one of the directions where the mount forces the belt to be strained; a saw-toothed stop part provided on the mount and adapted to extend in the right and left directions; and an engagement piece provided on the base and adapted to be moved between an engagement starting position with the stop part and a disconnection position from the stop part; a spring between the base and the engagement piece for energizing the engagement piece in a direction where the engagement piece is engaged with the stop part; a tapped hole made in one of the members of the base and the mount; and a bolt screwed into the tapped hole. Two locking states are made selectable: one is a first locking state wherein the bolt is tightened, whereby the engagement piece is fixed at the engagement starting position; the other is a second locking state wherein the engagement piece is fixed at the disconnection part. The bolt is loosened to set the engagement piece to an unlocked state, whereby the engagement piece is resiliently engaged with the stop part.

摘要： Gear belt tensioning apparatus is provided for controlling the tension in a gear belt for driving an internal combustion engine camshaft or the like. This apparatus includes a tension roller which engages directly with the gear belt and which is controlled by a temperature responsive control element. In order to accommodate for changes in temperature of the internal combustion engine, the control element is composed of a plurality of stacked bimetal dish-shaped spring members arranged in a cylindrical recess of an abutment fixed to the engine housing. These spring members are arranged in packets of four members each, which packets are then arranged so as to have the spring members of one packet facing in the opposite direction of the next adjacent packet of spring members.

摘要： A belt or chain tensioner has a tension rod which is urged by a compression spring. The forward stroke of the tension rod is normally released and the backward stroke of tension rod is locked normally by a locking component and released only when the retreating force of tension rod, due to the counterforce of the belt or chain, exceeds the gripping force of the locking component.

摘要： A device which maintains a predetermined tensioning force on the endless drive belt for vehicle accessories by use of a one-way clutch which prevents return of the tensioning means from its forwardmost tensioning position. In the preferred embodiment, a cylindrical shaft is mounted in a fixed position adjacent the drive belt. A roller clutch assembly is mounted on the shaft and includes an outer clutch housing rotatably mounted on the shaft. An outwardly extending lever is attached to the clutch housing and has an idler pulley rotatably mounted on the extended end of the lever. The pulley is moved into tensioning engagement with the drive belt by a torsional spring which is telescopically mounted on the shaft and clutch housing. The spring moves the pulley in a belt tensioning direction. The one-way clutch assembly preferably includes a roller clutch which consists of a plurality of rollers which are interposed between and are biased by a plurality of leaf springs into a wedging relationship with the shaft surface and ramps formed on a bearing cup. The rollers permit free movement of the clutch housing and attached lever in the belt tensioning direction while preventing movement of these components and associated idler pulley in the opposite nontensioning direction because of the wedging action of the rollers.
