摘要： In a marine drive (10), a drive sleeve (50) between the propeller shaft (22) and the propeller hub (34) absorbs shock after the propeller (12) strikes an object by torsionally twisting between a forward end keyed to the propeller hub and a rearward end keyed to the propeller shaft. The drive sleeve is composed of a plastic material providing torsional twisting angular rotation at a first spring rate less than 100 lb. ft. per degree from 0.degree. to 5.degree. rotation, a second higher spring rate beyond 5.degree. rotation, and supporting over 1,000 lb. ft. torque before failure.

摘要： A torque limiter having an outer ring, an inner ring mounted in the outer ring and a shaft inserted in the inner ring. The outer ring is formed on the inner peripheral surface thereof with a plurality of tapered surfaces. Rollers are mounted between the tapered surfaces and a cylindrical outer peripheral surface of the inner ring. Torque setting springs are provided at one side of the rollers to urge the rollers toward a narrower side between the tapered surfaces and the cylindrical outer peripheral surface. A coil spring is mounted between the inner ring and the shaft so as to bind around the outer peripheral surface of the shaft and having one end thereof secured to the inner ring. The coil spring is mounted so as to be tightened when the shaft rotates in a direction opposite to the direction in which the torque setting springs urge the rollers.

摘要： 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.
摘要翻译：根据本发明，由于在高压下的夹紧套筒的径向张力而产生的扭矩传递的安全联轴器具有释放阀。在由于过载而引起的轴相对于轮毂的旋转期间，释放阀打开，使得由于夹紧套筒中的压力的减小而导致扭矩传递被中断。在旋转之后，释放阀的挺杆被吸入释放阀，使得安全联接可以由于压力累积而再次投入运行，而不会发生任何破坏或磨损。

摘要： An anti-overload centrifugal clutch including a centrifugal clutch having a clutch drum secured to a driving shaft thereof and a group of centrifugal clutch shoes engaged with a driven shaft for contact with and movement away from the clutch drum. A group of centrifugal members are engaged with the driving shaft which are respectively forced to embrace the driven shaft by the action of an associated spring. The centrifugal members release this embrace when the rotation of the driving shaft reaches a predetermined rotational speed.

摘要： A torque-limiting device is provided which has a rotatably mounted driving member and a driven member. The driving member is connected to a spring cage member through a torsion spring. A clutch spring is disposed to provide frictional driving engagement between the cage member and the driven member. The clutch spring and the driving member are provided with coacting surfaces to release the driving engagement between the cage member and the driven member when a given angular displacement between the cage member and the driving member occurs. The angular displacement between the driving member and the cage member will be proportional to the torque applied by virtue of the torsion spring connection between the driving member and the cage member.
