FEED CHAIN AUTOMATIC TENSIONER |
摘要 |
An automatic tensioning system for a chain drive system of a rock drill assembly is disclosed. A hydraulic cylinder is coupled to one end of the feed channel of a rock drill assembly. When pressurized hydraulic fluid is provided to the hydraulic cylinder, a plunger within the hydraulic cylinder pulls on a tensioner sprocket, which in turn provides tension to the chain of the chain drive system. This allows for a constant tension to be applied to the chain throughout a long duration of operation as opposed to a manually adjusted chain drive system in which the chain tension varies during operation in between manual adjustments. |
