履带式推土机传动系统扭转振动是机身振动与噪声的重要来源,为了防止扭转共振的产生,在发动机飞轮加一扭转减振器,不但能调整传动系统的固有频率还能有效衰减发动机激励的传递。介绍了目前常用的3种扭转减振器,弹簧扭转减振器、橡胶扭转减振器以及尼龙盘扭转减振器,从结构、工作原理、结构尺寸等方面对几种减振器进行了比较说明。
Torsional vibration of the track-type bulldozer drive system is an important source of vibration and noise of the fuselage. To prevent torsional resonance, a torsional vibration damper is added to the engine flywheel to not only adjust the natural frequency of the transmission system but also effectively attenuate transmission of engine excitation. . Three kinds of commonly used torsional vibration dampers, spring torsional vibration dampers, rubber torsional vibration dampers and nylon disc torsional vibration dampers are introduced. Several types of shock absorbers are compared in terms of structure, working principle and structure size. Instructions.
