み部との位相の一致により接触爪が前記凹陥部に没入し
たとき前記検知板の変位を検出するリミットスイッチを
設けてなることを特徴とする過負荷保護装置。In an overload protection device in which means is interposed between the input side and the output side to interrupt transmission of torque exceeding a set value, a circular concave portion is formed at the center of the pulley on the side surface of the pulley on the input side or the output side, The front surface thereof is integrally provided with a lid portion in which a female spline-shaped window with a smaller diameter than the recessed portion is engraved, and the lid portion is prevented from rotating on the central axis passing through the center of the pulley and serving as the output side or input side. A detection plate is fitted so as to be slidable in the axial direction, and a boss end face of the detection plate facing the lid portion is slidable in the radial direction at an angle corresponding to the notch of the female spline-shaped window. In addition, in the protruding state, it overlaps with the peak of the female spline-shaped window,
A plurality of contact claws that can pass through the notch are provided, a member is provided for biasing the contact claws in a protruding direction, and a means for biasing the detection plate in a direction to press the contact claws against the lid part. further comprising a limit switch that detects displacement of the detection plate when the contact claw is recessed into the recessed part due to phase matching between the contact claw and the notch of the female spline window. Overload protection device.
