REMOVER Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: remover has a crosspiece, grippers with teethed sectors hinged on it and lugs hinged on the grippers and made as a double-arm lever. One arm has semi-spherical heads with acute-angled teeth, the other one is designed for interacting with the wedge-shaped surfaces made on the lower part of the nut carrying a power transmission screw serving as a reinforcing agent for the lugs. The remover also has a slipper with rack segments for interacting with the teethed sectors of the grippers, with the segments being placed on the cylindrical stem of the nut having the bosh from the side of the larger base of the upper face end of the slipper fixed on the tail end. EFFECT: created additional force of capturing the lugs and decreased load on the teeth of the rack gear between the nut and the grippers. 1 cl, 5 dwg
