The working principle of the invention is as follows:
let the inner ring 10 rotate at NInner partThe outer ring 30 has a rotational speed of NOuter coverThe rotation speed of the rotation locking part 20 is NLocking device。
The screw joint between the rotation locking portion 20 and the second cylindrical portion 13 is provided with lubricating oil, which reduces the friction coefficient between the rotation locking portion 20 and the second cylindrical portion 13.
Suppose that the inner hole 11 of the inner ring 10 is internally connected with a driving shaft, and the outer ring of the outer ring 30 is connected with a driven shaft, and suppose that N is NOuter cover>NInner partWhen the one-way bearing is in a separated state, the inner ring 10 and the outer ring 30 do not contact and rotate respectively; when the rotational speeds of the inner ring 10 and the outer ring 30 are equal, N isOuter cover = NInner partNo pulse magnetic field exists between the outer ring 30 and the rotation locking part 20, and the rotation locking part 20 only rotates under the drive of the second cylindrical part 13;
when N is presentOuter cover<NInner partWhen the rotating speed difference is generated between the magnet 21 and the outer ring magnet 33, an alternating acting force is generated between the magnet 21 and the outer ring magnet 33, when the alternating acting force is increased to overcome the static friction force between the rotating locking part 20 and the threads of the inner ring 10, the rotating locking part 20 rotates slowly relative to the inner ring 10 under the action of the alternating acting force, and at the moment, N isOuter cover<NLocking device<NInner partAnd further, the rotation locking portion 20 moves on the inner ring 10 towards the first positioning portion 40 until the outer ring 30 is pushed to be locked with the inner ring 10, and after locking, the inner ring 10 drives the rotation locking portion 20 and the outer ring 30 to synchronously rotate, so that the driving shaft drives the driven shaft to synchronously rotate.
When the speed of rotation of the driven shaft increases again, i.e. NOuter cover>NInner partThe difference in rotational speed is again generated between the magnet 21 and the outer ring magnet 33, and an alternating force is generated between the magnet 21 and the outer ring magnet 33, and when the alternating force is increased to overcome the static friction force between the thread of the rotation locking portion 20 and the thread of the inner ring 10At this time, the rotational speed of the rotational lock portion 20 becomes faster relative to the inner ring 10 by the alternating force, and at this time, NOuter cover>NLocking device>NInner partFurther, the rotation locking portion 20 is moved on the inner ring 10 in a direction to approach the stopper portion 15, and the inner ring 10 and the outer ring 30 are unlocked, so that the transmission of the driving shaft to the driven shaft is stopped.
