一种液压张紧式伐木机链锯控制机构
摘要：
本发明公开了一种液压张紧式伐木机链锯控制机构，包括安装座、用于安装链条的导板以及驱动链条转动的驱动装置，还包括安装在安装座上并可相对其转动的链锯控制块，链锯控制块内设有将其压紧的内圈，链锯控制块一端设有可驱动导板往复位移以使链条张紧或松开的液压张紧装置；安装座、内圈、链锯控制块、液压张紧装置、导板内均设有润滑油道，且安装座、内圈、链锯控制块、液压张紧装置、导板的润滑油道依次连通并延伸至链条上。本发明的链锯控制机构，结构紧凑、使用方便，通过液压张紧的方式实现对链条的张紧和松开，提高了链锯更换工作效率，并通过内置在各个部件中的油路连通对所有的转动机构实现自动润滑，有效延长了链锯的使用寿命。
摘要（英）：

The invention discloses a chain saw control mechanism of a hydraulic tensioning type feller. The mechanism comprises an installing base, a guiding plate used for chain installing, a driving device used for driving a chain to rotate and a chain saw control block installed on the installing base and rotating relative to the installing base, an inner ring used for closely pressing the chain saw control block is arranged in the chain saw control block, and a hydraulic tensioning device capable of driving the guiding plate to reciprocatingly move to make the chain tensioned or loosened is arrangedat one end of the chain sew control block; lubricating oil passages are arranged in the installing base, the inner ring, the chain saw control block, the hydraulic tensioning device and the guiding plate, are successively communicated and extend to the chain. The chain saw control mechanism is compact in structure and convenient to use, tensioning and loosening of the chain are achieved in a hydraulic and tensioning mode, the replacing work efficiency of the chain is improved, the oil passages in all the components are communicated with all rotating mechanisms to achieve automatic lubricating,and the using life of the chain is effectively prolonged.
