上海—50拖拉机变速箱的减振研究

Vibration Damping of SH-50 Tractor Gear box

对上海—50拖拉机变速箱振动的测试分析表明,其主要振源是常啮合齿轮副,因而采取减振措施,分别以误差较小的直齿圆柱齿轮和斜齿轮取代原常啮合齿轮副,使该变速箱的振动明显降低,收到了显著的减振效果。

Mcasuring and analysing indicated that the main vibration source of SH-50tractor gcarbox was the constant mesh gears pair in the box., For this reason.theconstant-mcsh gears pair are replaced by more precision straight spur gears and bevel gears.The effect is outstanding and the vibration is greatly reduced.
