The working principle of the roller bearing clutch

Aug 21, 2015

Roller bearing clutch working principle and tapered thread tightening process is similar, it is arranged according to the spiral angle of the roller replacement of taper thread screw tooth and the formation of the roller bearing clutch, roller in the inner and outer rings of rolling on the road was a right-handed arrangement, when the outer ring in torque starting to reverse the clockwise rotation, through the action of the force of friction drives the roller to rotate, due to the axis of the roller and roll axis angle between beta and roller motion is decomposed into two parts, is about the axis of rotation and movement along the axis.Because of the structure to ensure that the inner and outer ring and roller three in the direction of the outer ring can be moved along the axis of the outer ring to the right movement caused by the inner and outer ring spacing between the law to reduce the pressure on the roller and the wedge tight, inside and outside the ring to rotate at the same speed.And when the outer ring relative to the inner ring of the movement, the outer ring to the left to move, the inner and outer circle between the law to change the distance between the roller, the roller free rotation, so that realize the roller bearing clutch function.And when the outer ring relative to the inner ring of the movement, the outer ring to the left to move, the inner and outer circle between the law to change the distance between the roller, the roller free rotation, so that the roller bearing clutch  function.If the inner and outer ring is arranged in the left and the outer ring of the inner ring, and the opposite of the above motion is in the opposite direction, when the outer ring rotates in a clockwise direction, the clutch wedge is tightened, and the anti clockwise rotation is reversed.
