摘要： An annular shear valve protection member is disposed on an outer circumferential surface of a circumferentially extending portion of a cutting portion of a shaft member which is positioned radially outwards of shear valves and in the same axial position as the shear valves. Maintenance work such as replacement of shear valves of a torque limiter is performed by switching as required the state of the shear valve protection member 7 between a tightly attached state in which the shear valve protection member is not allowed to move relatively to the outer circumferential surface of the circumferentially extending portion and a tight attachment cancelled state in which the shear valve protection member is allowed to move circumferentially relative to the outer circumferential surface of the circumferentially extending portion by changing the diameter of the shear valve protection member by an operating portion of the shear valve protection member.

摘要： A torque limiter includes a cylindrical member, and a shaft member which is fitted rotatably in the cylindrical member. The cylindrical member has a main body portion having in an interior thereof an oil pressure expansion chamber for pressing an inner circumferential surface of the cylindrical member against an outer circumferential surface of the shaft member and an oil release passage which is opened to the oil pressure expansion chamber at one end portion while being closed tightly at the other end portion and which is positioned further radially outwards than an outer circumferential surface of the main body portion. When the cylindrical member stays still relative to the shaft member, the other end portion of the oil release passage is accommodated within a cap member which is screwed to be fixed in a threaded hole. When the cylindrical member rotates relative to the shaft member, the other end portion of the oil release passage is broken by the cap member, whereby the oil release passage is opened to the outside. When the cylindrical member is rotated relative to the shaft member in such a state that the cap member is not screwed in the threaded hole and in such a state that the oil release passage is not opened to the outside, the other end portion of the oil release passage moves in the circumferential direction within circumferentially extended groove while being spaced apart from the circumferentially extended groove.

摘要： A shear valve protection member is disposed radially outwards of the shear valves and in the same axial position as the shear valves, which can be switched between a tightly attached state in which the strip-shaped shear valve protection member cannot move relatively to a cutting portion which connects to the other member by virtue of a frictional force generated between the cutting portion and itself by tightly attaching the cutting portion thereto in the radial direction and a tight attachment cancelled state in which the strip-shaped shear valve protection member can move in a circumferential direction relative to the cutting portion. The shear valve protection member can be switched between a position where the shear valves are covered with the shear valve protection member and a position where the shear valves are exposed from the shear valve protection member through the through holes therein.
