Abstract: An overload clutch, particularly for use with manually operated drilling tools, has a release or disconnect moment adjusted at a predetermined velocity as a function of the applied torque, whereby in normal, malfunction-free operation the clutch does not release or disconnect. In the case of a malfunction, for instance if the tool is blocked or seized, a rapid rise in the required torque occurs and the clutch, having inertia or damped by a volume change, releases or disconnects and immediately interrupts the torque transmission from the tool motor to the drilling member. A purely mechanical solution for the safe use of such drilling tools is afforded by the provision of a two-part shaft with two co-axially guided shaft parts (3, 7). A drive element (2) is engaged in positively locked manner and acts on a drive side shaft part (7) by a mobile thread or a sliding link (4), so that the drive element (2) prestresses a spring (5) depending on the applied torque.

Abstract: A lock nut having a tapered portion at one end thereof is screwed halfway through an output shaft that transfers motion to a steering mechanism. A tapered fitting hole formed through an axis of a worm wheel is fitted onto an outer circumference of the tapered portion with a slip plate interposed therebetween. By tightening the lock nut, the worm wheel is pressed and fixed to a support portion formed on a portion of the output shaft, and a worm directly connected to an output side of a steering assisting electric motor is made to engage with a gear formed on the outer circumference of the worm wheel. In normal operation, the torque of the electric motor is transmitted to the worm wheel via the worm, and further on to the output shaft via friction on the slip plate. Upon application of an excessive rotational torque in the event of a motor lock, slippage occurs on the slip plate to allow free rotation of the output shaft.

Abstract: According to the invention, a safety coupling, the torque transmission of which takes place as a result of the radial tension of a clamping sleeve which is under high pressure, has a release valve. During a rotation of the shaft relative to the hub, caused by overloading, the release valve is opened, so that the torque transmission is interrupted as a result of a reduction of the pressure in the clamping sleeve. After rotation, the tappet of the release valve is drawn into the release valve, so that the safety coupling can be put into operation again as a result of a pressure buildup, without any destruction or wear occurring.

Abstract: A radial ball torque limiter having a member with an annular wall defining a cavity with a plurality of rows of internal teeth extending circumferentially along the interior of the annular wall, an input shaft extending into the cavity, and one or more caged ball assemblies surrounding the input shaft with each having a circumferential row of balls loosely held by a generally annular cage to engage in ball-receiving recesses between adjacent teeth and the cage has a hub connected to the input shaft. A circular member positioned radially inward of the balls engages and yieldably holds the ball in the ball-receiving recesses during torque transmission from the input shaft to an output shaft and is yieldable upon the application of excessive torque to permit the balls to move inwardly and travel past the teeth to limit the value of the torque that is transmitted.

Abstract: A shaft coupling which can prevent trransmission of side loads in the event of angular or parallel misalignment of end-to-end shafts and which can also provide non-destructible overload protection. A pair of independent translatable devices spaced apart along the axis of the coupling, and set in planes at right angles to the axis and to each other can translate independently to permit free nutating motion of an intermediate torque-transmitting coupling member. Spring loaded balls on the ends of the independent devices decouple the shafts from each other in the event of overload. Embodiments can achieve all of the above with virtually zero back lash.

Abstract: An overload apparatus is shown as an overload single position clutch having a drive ring which is reciprocated by springs and by a cylinder slideable on a piston by fluid pressure. The drive ring includes a multiplicity of ball receiving cavities. A sheave mount is further provided including an integral interface disc having a multiplicity of ball carrying cavities. Balls are captured within the ball carrying cavities by a ball cage secured to the mount. The ball cavities have diameters less than the balls and a shape and size such that the balls do not touch the closed ends or sidewalls of the cavities but rather the open ends form seats for the balls. The ball carrying cavities have diameters greater than the diameters of the ball receiving cavities to predispose the balls to cam out of the ball receiving cavities in the event of reaching a torque overload level.

Abstract: A combined variable speed viscous coupling and bearing includes a rolling element bearing that supports a driven member for relative rotation on a powered member. A viscous grease interposed and sealed with respect to the rolling elements of the bearing acts as a variable speed drive, frictionally retarding the rolling of the rolling elements when the powered member turns below a certain critical speed, thus causing the driven member to turn with the powered member in a one-to-one relationship. Above the predetermined critical speed, the rolling elements roll sufficiently through the viscous material to allow the powered member to overrun the driven member. In a preferred embodiment, the invention is disclosed as a variable speed drive for the cooling fan of a vehicle alternator.

Abstract: A system for transmitting motion between a driving component and a driven component includes a torque release clutch for transmitting motion between the components until a predetermined amount of force is required to do so, whereupon the clutch releases. The clutch includes a pair of relatively movable members, at least one ball, and an expandable ring. The ball has one position wherein the ball is in engaged or interfering relationship between the pair of members whereby movement of one member effects movement of the other member. The ball has another position wherein the ball is out of interfering relationship with or disengaged from at least one movable member. The expandable ring is mounted on one of the movable members and is engageable with the ball to hold the ball in engaged position until a force applied to the ball exceeds a predetermined amount, whereupon the ring is forced to expand and allow the ball to move to the disengaged position.
