偏心连杆振动输送机两种激振方式的力学行为分析

Analyses on the Mechanic Behaviour of the Two Methods in Exciting Vibration Conveyors with Eccentric Connecting-rod

偏心连杆振动输送机（以下简称振机），因其良好的性能在卷烟厂制丝线上获得广泛应用。其常见的激振方式有刚性连杆直接激振和弹性连杆间接激振两种形式。由于激振方式不同，对振机的性能影响较大。本文对上述两种激振方式的力学行为作了对比分析，并着重对激振弹簧等元件的功能进行了探讨，以便为该设备在选用、引进、吸收、改造和维修时提供参考依据。

Vibration conveyors with eccentric connecting-rod are widly applied in production line of cigarette factores. The general ways for exciting vibration is acted by the stiff connecting-rod or the elastic connecting-rod, in turn, called directly exciting vibration or indirectly exciting vibration. Their effects properties are different because their forms of exciting vibration are different. This paper analyses and compares the mechanic behaviour of exciting vibration by the stiff connecting-rod or elastic connecting-rod, and discusses the functions of elements of exciting vibration. So it had met the demand for application.
