摘要： A torque multiplier apparatus includes an input pinion, a geared torque multiplier mechanism, and an input retainer. The input pinion and the input retainer include first and second identical connectors so that a detent stud can be positioned in either one of the first and second connectors, allowing the torque multiplier to be used for increased torque (and reduced speed) or for increased speed (and lesser torque). A related method includes engaging the driving tool with the first connector and the socket with the second connector to provide an increased torque on a socket to break loose a fastener, and flipping the torque multiplier so that the driving tool engages the second connector and the socket engages the first connector to provide an increased speed of torsional rotation to more quickly remove the fastener from the shaft. The detent stud is torsionally shearable, thus preventing over-stressing and damaging the tool.

摘要： Axially extending lobes extend radially from an internally threaded nut and form axial troughs that receive a respective axial cone mounted in the socket of a driver, the cones being rotatably driven against the lobes to apply a threading torque to the nut. At a predetermined torque, an axial outer radial end portion of the material forming the lobe is plastically deformed, but not sheared off, thereby allowing the socket to rotate and the cones to advance against the next respective lobe. The deformed lobe indicates to the user that the nut was properly torqued and the deformed material does not shear off thereby indicating that the nut had not been tampered with. To permit relaxation, a second torquing could be done at a later time.

摘要： A screw can be driven home in response to the application of a preselected torque by placing over the head of the screw a tubular first section of a plastic adapter wherein the first section is connected with a polygonal second section by a frangible joint. The joint breaks in response to the application of preselected torque to the second section, and the separated second section then exposes a destructible diaphragm which is provided in the first section and overlies the head of the screw. The head can be engaged by the working end of a tool in response to at least partial destruction of the diaphragm. The first section can be of one piece with the head or it can be affixed thereto by an adhesive or is in mere frictional engagement with the head. Integrity and accessibility of the diaphragm indicate that the screw was driven home in response to the application of preselected torque as well as that the head of the screw was not tampered with subsequent to separation of the second section from the first section of the adapter.

摘要： A torque limiter for limiting the amount of torque applied to off-the-shelf fastening members which are not themselves inherently torque limiting. The torque limiter is separate from the fastening member and is applied thereto to grippingly engage that fastening member. The torque limiter undergoes tension induced breakage upon application of a predetermined torque thereto. The tension induced breakage frees the torque limiter from gripping engagement with the fastening element to thereby prevent further torque application to the fastening member via the torque limiter.

摘要： A torque-limiting driver has a handle, a body, a torque-limiting assembly and a work-piece engaging tip. The torque-limiting assembly includes an upper and lower shank that have a plurality of teeth circumferentially spaced. The teeth have a vertical face, an inclined face, and a flat peak. There is a spring for applying pressure across the upper and lower shank with multiple washers interposed between the lower shaft and spring. In some instances, there is a round square drive with arched catches having preselected radii to assure operation over certain cycles at selected torque and to reduced nose cone damage and breakage at a predetermined inch pounds of torque.

摘要： A speed-increasing mechanism and a clutch mechanism are provided between a speed-reduction gear train and planetary gear trains, to realize a small-torque and high-speed rotation during a light load condition and a large-torque and low-speed rotation during a heavy load condition. A motor is actuated by a relay. An auxiliary motor switch, closing a contact of the relay, is provided at a motor housing to facilitate an operation of a shear wrench during a work where a bolt is fastened upward from below.

摘要： A device comprises a housing having a planetary gear reduction mechanism accommodated therein and a handle projecting therefrom, an electric motor or like rotation source attached to the housing for inputting power to the reduction mechanism, an outer socket coupled to an internal gear of the reduction mechanism and engageable with a nut, an inner socket coupled to a planetary gear support frame of the reduction mechanism and engageable with a bolt tip, and a torque detecting control mechanism for detecting a nut tightening force to discontinue supply of power to the rotation source upon the tightening force reaching a predetermined value. A friction ring is provided between the housing and the support frame coupled to the inner socket to effect frictional engagement therebetween. A definite axial tension is available by rotating the outer socket, i.e., the nut, with the inner socket in a fixed state. Even if the bolt should rotate about its axis, the support frame slips, whereby the tightening device is prevented from turning around in its entirety.
