Roller bearing clutch
As shown in figure roller bearing clutch is mainly composed of inner ring, roller, outer ring, roller cage, stop, card ring, spring piece, seal ring, etc.
Working principle:
Working principle of roller bearing clutch is similar with the process of taper thread tighten, it is in a certain order of spiral Angle of roller instead of taper thread screw teeth and form of clutch, roller, roll outer ring road are arranged right, when the outer torque under the action of began to counterclockwise rotation, through the role of friction drive roller rotation, due to the Angle between the axis of the roller and raceway axis beta, the movement of the roller is broken down into two parts, namely around the axis of rotation and movement along the axis. Guarantee on the structure of the roller, inner or outer ring of the three only outer ring can move along the axis direction, the outer ring to the right leads to the normal distance between inner and outer ring, roller pressure and chocking, inner and outer ring rotates at the same speed. And when the outer ring relative to the inner ring has a clockwise movement, outer ring move to the left, the normal distance between inner and outer ring, roller rotation freely, it realize the function of clutch bearing clutch. If the inner and outer ring raceway are arranged a left-handed, is contrary to the above movements, outer ring rotates clockwise clutch chocking, counterclockwise rotation when the wedge.
