油鋸是一种手提式机械,在鋸木作业的整个过程中,均由鋸手携提。油鋸的振动主要来自两个方面,即发动机旋轉慣性力和鋸木时鋸鏈产生的冲击力。此外,鋸鏈銼磨不当,发动机調整不好,鋸手操作不熟练等也会引起振动,但主要是前述两种原因。油鋸产生的振动,絕大部分直接传向鋸手。为了減輕油鋸在工作中传向鋸手的振动,改善鋸手的劳动条件,人們采用了各种形式的減振措施,但总的說来,不外乎是在发动机与手把或手把与鋸手握手之間将振动切断或減弱。手把的減振比較簡单,而且可
The chain saw is a hand-held machine that is carried by saws throughout the sawing process. The vibration of the chain saw mainly comes from two aspects, namely the inertial force of the engine rotation and the impact force generated by the saw chain when sawing wood. In addition, improper chain sawing, poor engine adjustment, and unskilled saw operators can cause vibration, but mainly the two aforementioned reasons. Most of the vibrations generated by the chainsaw are directly transmitted to the saw. In order to reduce the vibration transmitted to the sawing hand during the work of the chain saw and to improve the working conditions of the hand saw, people used various forms of vibration reduction measures, but overall, nothing more than the engine and the handle or handle. Vibrate or weaken the vibration between shaking hands with sawing hands. The damping of the handle is relatively simple and can be
