万向联轴节传动是一种变角传动,它能传递相交两轴之间的扭距。其特点是它在传动过程中,当两轴之间的夹角变化时,传动并不中断,只是瞬时传动比有所变化。所以,它尤为适用于铰接式底盘(或机架)的林业机械,其主要原因就在于万向联轴节保证铰接式底盘的林业机械在崎岖不平的林地内正常运行作业。但是,单万向联轴节传动中其主动轴以ω_1等速回转时,从 Universal joint drive is a variable angle drive, it can pass the torque between two intersecting axes. It is characterized by its transmission process, when the angle between the two axes changes, the transmission is not interrupted, but the instantaneous transmission ratio has changed. Therefore, it is especially suitable for articulated chassis (or frame) of forestry machinery, the main reason is that the universal joint to ensure the articulated chassis of forestry machinery in the rugged woodland to operate normally. However, the single universal joint drive in its drive shaft to ω_1 constant speed rotation from
