    Abstract: A mechanical protection device including: a transmission shaft having a main axis of rotation and an element that is frangible under a torsional overload; a movable member secured to the transmission shaft to rotate about the main axis and configured to move radially outwards relative to the main axis from a first position to a second position; a spring urging the movable member towards the first position; and a tangential abutment configured to stop rotation of the movable member about the main axis when the movable member is in the second position. The movable member and the spring are calibrated so that from a predetermined trigger angular speed the movable member moves from the first position to the second position under effect of centrifugal force greater than prestress of the spring.

    Abstract: A shear coupling assembly utilizes a second coupling member, a first coupling member and a locking member which is inserted into a bore in the first coupling member to connect between the second coupling member and the first coupling member. In embodiments where a pretension is applied to the shear neck, the locking member maintains the pretension in the shear neck. The bore of the first coupling member has a profiled section which corresponds to a profiled section on the second coupling member which when mated together permit torque to be transferred for co-rotating the second coupling member with the first coupling member for use in rotary pump operations. Advantageously, the profiled portions and the shear neck are encased in the bore of the shear coupling assembly and are protected from corrosive wellbore fluids.

    Abstract: A torque transmitting cardan shaft including within the shaft an adapted intermediate member or shaft, which has a first end section, that is intended for a rotationally rigid co-action with a first universal joint yoke and a second end section, opposite the first end section, intended for a rotationally rigid co-action with a second universal joint yoke. The intermediate member or shaft and its end section is configured as and comprises two parts or subsections, which are mutually joined via a safety coupling arrangement, by means of which a free coupling of the subsections from one other can be ensured immediately after the torque, between the subsections, exceeds a predetermined value, determined by the construction of the safety coupling arrangement. An end section and its universal joint yoke includes an axially orientated cylindrical groove or recess, which has a center axis that is co-ordinated with or aligned with a rotational axis of the first end section and its co-ordinated universal joint yoke. The circular groove or recess is dimensioned to enable the enclosure of a major cylindrical part of the safety coupling arrangement and its safety unit first part and co-operate with a second part formed as a disc. The end section or extension and its yoke are integrally formed in one single piece.

    CPC classification number: F16D9/08

    Abstract: A torque-limiting coupling may be used to provide a torsion drive between an engine or motor and a driven accessory. If an accessory should experience a catastrophic failure a torsion limit is exceeded and a spline breaks away from the coupling. This guarantees that the internal engine gearing used to drive the accessory is not compromised and interfering with essential moving parts inside the engine. Further, a misalignment compensation limits the side load and wear that occurs when coupling two precision shafts with little clearance on the bearings. With a misalignment coupling, the mount can be slightly out of parallel with no negative effects.

    Abstract translation: 可以使用扭矩限制联接器来提供发动机或电动机与从动配件之间的扭转驱动。 如果配件遇到灾难性故障，则超出扭转极限，并且花键与联轴器脱离。 这确保用于驱动附件的内部发动机传动装置不会受到损害，并干扰发动机内部的主要运动部件。 此外，不对准补偿限制了在轴承上具有很小间隙的两个精密轴联接时发生的侧向载荷和磨损。 通过不对准耦合，安装座可以略微不平行，没有负面影响。

    Abstract: A coupling device has a pulley that receives rotational torque from an engine. The torque is transmitted to a shaft through a hub and a one-way clutch. A torque limiter is screwed on the shaft to fasten the inner ring of the one-way clutch onto the shaft. The torque limiter has a breakable portion. The torque is directly transmitted from the inner ring to the shaft when the torque is normal. If the torque exceeds the tightening torque of the torque limiter, the inner ring begins to slide and rotate, and drives the torque limiter in a tightening direction. As the torque limiter is tightened additionally, the tensile stress on the breakable portion is increased. Then, the breakable portion breaks and is separated in axial direction so that the coupling device disconnects torque transmission.

    Abstract translation: 联接装置具有从发动机接收旋转扭矩的滑轮。 扭矩通过轮毂和单向离合器传递到轴。 扭矩限制器拧在轴上，将单向离合器的内圈固定在轴上。 扭矩限制器具有易碎部分。 当扭矩正常时，扭矩从内圈直接传递到轴上。 如果扭矩超过扭矩限制器的拧紧扭矩，内圈开始滑动并旋转，并沿紧固方向驱动扭矩限制器。 当额定扭矩限制器被紧固时，可断裂部分的拉伸应力增加。 然后，可破坏部分断裂并在轴向方向上分离，使得联接装置断开扭矩传递。
