补充资料：自锁
| 自锁 self locking 机械在给定方向的驱动力作用下，由于摩擦原因无论驱动力多大都不能使机械运动的现象。对于移动副来说，如图1，作用在滑快A上的驱动力P，倾角为a，水平力Px＝Psina，摩擦力F＝fPx/ tga，式中f为摩擦系数。j=arctgf称摩擦角，以2j锥顶角的圆锥称为摩擦锥。若P作用在摩擦锥面内，即a＜j，Px＜F，则不论P多大，滑块都静止不动，即发生了自锁。若P作用在摩擦锥面上，即a＝j，Px＝F，此时处于临界状态，滑块将保持原来的等速运动或静止不动。对于转动副来说，如图2，以不通过回转轴线的力驱动构件转动，力P可看作是图2转动副大小和方向均相同的径向力与力偶M＝Pe的合成。力偶M驱动构件回转 ，同时由于径向力的作用在转动副中引起与P相等的总反力R。回转件所受的摩擦力矩Mf=f0Rr＝f0pr,式中f0为当量摩擦系数，r为转动件的半径。若令f0r＝ρ，则Mf=Pρ。以转动副轴心为圆心，以ρ为半径的圆，称为摩擦圆。若P的作用线与摩擦圆相割（在摩擦圆里边），Pe＜Pρ，则不论P多大，回转件也不转，即发生自锁。若切于摩擦圆，Pe＝Pρ，则处于平衡。
产生自锁的必要条件叫自锁条件。对于机械运动，其自锁条件为η≤0，式中η为机械效率。 |
