Multidirectional vibrating mechanical device

摘要

Device formed by two pulleys which rotate in opposite directions at different speeds, which carry, in their pin (axis) a cylinder which has three helical grooves machined on its outside, each pulley having joined to it a mass in the form of a circular sector and there being a second hollow cylinder concentric with the aforesaid cylinder, with helical grooves with angle of inclination which is inverse to those of the other cylinder, a mass of circular sector being joined thereto. <IMAGE>
