Abstract
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.
Claims7
An apparatus (100) for eliminating slack and vibrations of a chain (400) of a chain drive (1000), the apparatus (100) being configured to transfer the chain slack and vibrations through a sprocket wheel (80) connected to the chain (400), the apparatus (100) comprising:
- a piston-cylinder arrangement;
- a first piston (10), a cylinder (20) in which said first piston (10) is configured to reciprocate, said cylinder (20) configured to be filled with a first fluid, a grease port (70) defined in said cylinder (20) for introducing and dispensing said first fluid into said cylinder (20) or therefrom, a pump (76) in fluid communication with said grease port (70), a pressure sensor (72) fitted inside said cylinder (20) to sense pressure of said first fluid in said cylinder (20), said pressure sensor (72) configured to be in communication with said pump (76), said grease port (70) configured to enable operation of said pump (76) when said pressure sensor (72) senses a reduced pressure in said cylinder (20) in response to a slackening of the chain (400), and thereby reduction in pressure exerted by said first piston (10) on said first fluid inside said cylinder (20);
- a second piston (30) configured to reciprocate in a cavity (40) defined inside said first piston (10), said second piston (30) connected to said sprocket wheel (80) at one end (100a), a second compressible fluid filled in said cavity (40), arrangement of said second piston (30) is configured such that the vibrations received by said second piston (30) are damped by said second compressible fluid.
