One-way clutch with concave arc inner ring used for loading machine

The utility model discloses a one-way clutch with a concave arc inner ring, comprising a gear outer ring and an inner ring with concave arcs on the circumferential surface. An eccentric wedge block, a stop pin and a stop ring fixing the eccentric wedge block, a spring for causing the eccentric wedge block to generate the initial frictional force and an elastic stop ring for the shaft are provided between the gear outer ring and the inner ring with the concave arcs on the circumferential surface. The working surface of the eccentric wedge block respectively contacting the gear outer ring and the inner ring with the concave arcs on the circumferential surface is composed of two eccentric arcs. The circumferential surface of the inner ring with the concave arcs on the circumferential surface is evenly distributed with the concave arcs with the same radius r0 ; the eccentric wedge block is installed in the concave arcs. The utility model solves the problem of the load bearing torque; the torque can be improved 3. 5 times, and the contact stress reduces 35%; the one-way clutch with a concave arc inner ring fundamentally solves the problem of the service life of the one-way clutch in the reduction box of the loading machine with simple technology and more perfect reliability of using; the one-way clutch with a concave arc inner ring solves a big difficult problem puzzled the industry of the loading machine for a long term.
