To provide a simple-structured tensioner lever capable of consistently exerting a correct reaction force to various fluctuations of tension accompanying varying chain behaviors, whereby vibration and noise when the chain runs can be reduced. The tensioner lever of the present invention includes a lever body having a shoe surface that slidably guides a chain; a first pressing spring configured to have a first pressing arm extending from one end of a first helical part, with a distal end portion contacting the lever body to form a first loading point, and a first support arm extending from the other end of the first helical part, with a distal end portion contacting and being supported by a first support part provided to an attachment surface to form a first support point; and a second pressing spring supported on the lever body at a different position from that of the first pressing spring.

To provide a chain guide that can improve transportability and assembly operation efficiency, while also ensuring stable running of a timing chain and enhancing durability, with a simple structure. The chain guide has a guide shoe that slidably guides a chain, and a chain guide body that supports the guide shoe. A compression limiter having an attachment hole through which a mounting bolt for attaching the chain guide to an attachment target member passes is fitted in a fixing through hole extending through the chain guide body in a width direction thereof. A compression limiter holding mechanism is provided either to the compression limiter or to a hole rim part including the fixing through hole of the chain guide body in order to hold the compression limiter.

The skid steer manure spreader attachment includes a main bucket compartment, a cover, and a beater shaft. The bucket, cover, and beater shaft are preferably formed of welded steel. The bucket has an industry standard quick attach plate on the back so it can be quickly attached to any standard skid steer, and is a standard width. A hydraulic motor operates the beater shaft and the cover. The beater shaft has blades angled in two directions. The beater shaft spins forward so the beater blades through manure out of the top of the bucket, above the shaft. The hydraulic motor drives the top sprocket, and a chain drives the bottom sprocket. A tensioner pivots on one screw to allow the user to tension the chain as needed.

To provide a tensioner capable of preventing slipping between a rack portion and ratchet pawls and securing a large backlash with a simple structure. The tensioner includes a ratchet rotatably mounted on a housing and having a front pawl and a rear pawl spaced apart in a front and rear direction on a side face positioned opposite the rack portion. The ratchet includes an additional pawl formed between the front pawl and the rear pawl in the front and rear direction on the side face positioned opposite the rack portion.

An object of the present invention is to provide a chain drive system capable of reducing sliding resistance between a chain and a guide shoe, suppressing an increase, over time, in sliding resistance, and reducing wear on the guide shoe. A chain drive system according to the present invention includes a chain having a plurality of chain plates, a plurality of sprockets on which the chain is wound, and one or more guides each including, integrally or separately, a guide shoe having a chain-running surface, and slidably guiding, in presence of lubricating oil, the chain. At least one of the plurality of chain plates has a lubricant region retaining a solid lubricant.

A chain tensioner transmits power of a crankshaft provided in an engine to peripheral auxiliary devices and guides a chain belt that transfers engine oil. The chain tensioner includes a body portion that tensions the chain belt through a pivot, the upper surface of the body portion includes an oil guiding rib that collects the engine oil scattered from the chain belt to the upper part, one surface of the body portion in contact with the upper surface includes a pivot journal, and one surface of the body portion includes a first oil flow path that guides the engine oil to flow down to the pivot journal.

A stack of disk springs are placed between a second piston of a dual hydraulic variable force tensioner system and a hydraulic tensioner arm to allow much higher spring rates if desired. The springs may be stacked in multiple configurations to provide different spring rates. Package space can be reduced depending on the number of springs and orientations of said springs within the tensioner arm.

An articulated chain with alternating inner chain links and outer chain links which are each connected to each other by means of a chain joint, wherein each outer chain link comprises at least two outer link plates and two chain studs connecting them to each other, each inner chain link comprises at least two inner link plates and two joint sleeves connecting them to each other, and for forming a chain joint, one chain stud each of the outer chain link extends through a joint sleeve of the inner chain link. The joint sleeves of the inner chain links are embodied as winding sleeves and firmly connected to the inner link plates, wherein the sleeve joints of the two winding sleeves are positioned on the same side of a link plate's longitudinal axis and face each other, and the sleeve joints are arranged at a distance to the link plate's longitudinal axis and at a distance to an upper apex or to a lower inflection point of the winding sleeve.

To provide a universal design chain guide that can provide a position, track, and length of contact between the chain guide and the chain for optimal performance even when used with different types of chains. The chain guide includes a guide surface slidably guiding a running chain and at least one mounting part. The guide surface includes a first guide surface extending along a longitudinal direction and a second guide surface parallel to and protruding more than the first guide surface. The second guide surface protrudes from the first guide surface with varying heights along the longitudinal direction.

A method of fabricating a chain tensioner includes bending a sheet metal blank to form a connector portion perpendicular to a flat base. The connector portion has an arm extending beyond the base. The method further includes stamping an end of the arm to curl the end into a hollow cylinder having an axis perpendicular the flat base. Curling the end into a hollow cylinder may be performed in a series of stamping operations. The blank may define a gap which extends around a narrower portion of the arm after the end is curled into the hollow cylinder.
