摘要： The present disclosure discloses an apparatus (100) for eliminating slack and vibrations of the chain (400) comprising a piston-cylinder arrangement. A first piston (10) is configured to be displaced inside the cylinder (20) of the piston-cylinder arrangement and a second piston (30) is configured to be displaced inside a cavity (40) defined inside the first piston (10) with the axis of the cavity (40) being coaxial with the axis (A) of the cylinder. A lubricating oil passage (50) defined to pass through the first piston (10), the second piston (30) and the cylinder (20) of the piston cylinder arrangement. The apparatus facilitates reduction in vibrations, slack elimination and automatic lubrication of the chain drive.

摘要： A traction tensioning device which has one or more upper chain assemblies driven by an upper sprocket pulley and one or more lower chain assemblies driven by a lower sprocket pulley. Each of the upper and lower chain assemblies has a plurality of pads mounted to the chain assemblies. The upper chain assembly is mounted to a movable platen. The lower chain assembly is mounted to a fixed platen. The upper chain assembly and the movable platen are raised and lowered with respect to the lower chain assembly thereby creating a tension on a strip of material passing between the upper and lower chain assemblies.

摘要： An autonomous hydraulic expansion and contraction apparatus comprises a fixing unit, a cylinder unit, a support unit, a piston unit, a valve unit and oil supply parts. By controlling the expansion and contraction length of the support part by a simple manipulation of the valve part by moving the lever, the autonomous hydraulic expansion and contraction apparatus can be easily expanded and contracted to the combined length of the expansion and contraction equipment, and additionally, the convenience of use can be enhanced.
