Saw frame oscillating mass compensation system - involves double wound pendulum as second counterweight hinged to rotatable carrier

摘要

The device for compensation of oscillating masses in saw frame operation is esp. for use where there is one counterweight seated off-centre on the flywheels on both sides Another runs coaxially but counter to the first, elastically coupled to the flywheels for revolution at the same rate. The resultant gravity forces counter-act those of the saw frame. Each of the second counterweights is a double-wound pendulum hinged to a rotatably driven carrier (7). The radius of rotation and the length of the two guide-rods (9) between the pendulum weight (11) and carrier are such that the factor for relationship between inherent frequency and revolution rate is less than one.
