    摘要： The present invention is directed to decrease the impact sound of the ratchet mechanism generated at the time of piston retraction. The tensioner includes a piston 3 slidable in the piston bore 2a of the housing 2 and an expandable circlip member 5 engageable with the engagement groove 3a of the piston 3. The piston bore 2a has a guide groove 20 formed therein that has front and rear stop surfaces 20a, 20b adapted to contact the circlip member 5. The engagement groove 3a is formed by a round seat portion S0 that the circlip member 5 is adapted to seat, a piston-retraction restricting portion S0S1 that is formed on the front side of the round seat portion S0 and a piston-advance permitting portion S0S2 that is formed on the front side of the round seat portion S0. The piston-retraction restricting portion S0S1 permits the circlip member 5 to travel a short distance toward the front side along the rear side stop surface 20b to allow for an enlargement of the circlip member 5 and to restrict retraction of the piston 3 when the piston 3 retracts and the circlip member 5 contacts the rear side stop surface 20b of the guide groove 20.

    摘要： The present invention provides a silent chain that can reduce friction loss during travel of a chain. A silent chain 1 is configured by stacking a large number of link plates 2 comprising a pair of tooth parts 22 and pin holes 21 in the thickness direction and the lengthwise direction, and also arranging guide plates 4 on the outermost side of the link plates 2, and coupling the link plates 2 and the guide plates 4 by means of connecting pins 3. In this case, hemispherical protruding parts 45 which can come into sliding contact with guide parts 56B of a chain guide 56 and guide parts 57B of a tension arm 57 during travel of the silent chain 1 are provided on an outer side surface 4A of the guide plates 4. By virtue of this, the contact between the silent chain 1 and the chain guide 56 and tension arm 57 is made to be point contact, and friction loss during travel of the chain can be reduced.

    摘要： The present invention is directed to decreasing noise from the onset of engagement with the sprocket teeth till seating thereon and also to reducing wear to the silent chain and the sprocket. A face (a) of a sprocket tooth, which contacts the chain at the onset of engagement, has a tooth profile that is an envelope (l) of trajectories described by the inner flank surface (23) of the link plate (2) when the chain moves linearly toward the sprocket (S) and engages with the sprocket (S) without causing a chordal action. A crest (b) of the sprocket tooth, which contacts the chain (S) at the time of seating on the sprocket tooth, has a tooth profile that is an envelope (m) of trajectories described by the crotch (25) of the link plate (2) when the link plate (2) rotates around the connecting pin during the wrapping motion of the chain around the sprocket (S). A connecting surface (c) that connects the face (a) of the sprocket tooth with the crest (b) is formed of a curved surface which is inscribed in the envelope (l) of the trajectories during the linear motion of the link plate and the envelope (m) of the trajectories during the rotational motion of the link plate.

    摘要： According to an embodiment of the invention, blade tensioner (1) is configured with blade shoe (2) having chain sliding face (20a), base (4) that supports base part (2a) of blade shoe (2) while allowing it to pivot freely, and blade spring (3) in which base part (3a) is fixed to tip part (2b) of blade shoe (2). Warped part (3b) provided at the tip contacts inner face (20b) of blade shoe (2), and curved part (3c) provided at the midpoint of base (4) contacts sliding face (4a) of base (4). In this case, the damping force of the blade tensioner increases due to sliding resistance generated between warped part (3b) of blade spring (3) and inner face (20b) and between curved part (3c) and sliding face (4a).
