FIELD: mechanical engineering. SUBSTANCE: apparatus has one member with pin 1 and other member with pin receiving opening 2. Pin 1 has circumferential cams 5 extending in radial direction beyond imaginary cylindrical surface 4. Opening has channels 8 extending in radial direction beyond imaginary cylindrical surface 7, with number of channels 8 being equal to that of cams 5. Cams 5 and channels 8 have wedge-shaped profile whose wedge-shaped surfaces correspond to characteristics of logarithmic spiral relative to axis of pin 1 or opening 2. Slope of engageable wedge-shaped surfaces has such value that when predetermined relative motion between pin 1 and opening 2 occurs and, as a result, contact between their surfaces is set by creating pressure in joints, self-braking frictional joining free of gap is provided independent of direction of rotation and direction of applying loading (radial or axial direction) between pin 1 and opening 2. EFFECT: increased efficiency, enhanced reliability in operation. |
