てあることを特徴とする油圧式トルクレンチ。 A main shaft is provided in an oil cylinder that is interlocked and connected to a rotationally driven rotor so as to be relatively rotatable; Blades are provided in the protruding direction, and the outer circumferential surface of the main shaft is spaced apart from each blade in the circumferential direction by a distance corresponding to 1/2 of the circumferential spacing between the blades. A first sealing surface that comes into close contact with each of the main shaft side sealing surfaces in an oil-tight state, and a second sealing surface that comes into close contact with the protruding end surface of each of the blades in an oil-tight state.
In the hydraulic torque wrench, one of the blades is configured to form a sealing surface to form a high pressure chamber in one direction of rotation of each of the blades and a low pressure chamber in the other in the specific rotational phase.
The pins are made to protrude outward from both ends in the direction of the rotation axis, and the pins are brought into sliding contact with the upper and lower covers of the oil cylinder, twice for each rotation of the oil cylinder. A hydraulic torque wrench, characterized in that a cam groove is formed that separates the blade from the second seal surface only in one of the obtained specific rotational phase states.
