An excessive torque releasing type clutch apparatus comprises an outer ring, an inner ring arranged radially inside and coaxially with the outer ring and rotatably relative to the outer ring, a torque transmitting portion capable of transmitting torque between the outer ring and the inner ring, and a restricting mechanism for restricting excessive torque from being input from an input torque transmitting member to a driving ring of the outer ring and the inner ring and restricting excessive inverse torque that is input to a driven ring of the outer ring and the inner ring from being input to the input torque transmitting member. Treatment steps for securing strength of constituent members of the clutch apparatus in manufacturing be simplified or omitted.

A measuring device with a crankshaft and a load cell for determining a radial force acting on the crankshaft having a receiving sleeve for receiving a bearing ring and a fastening ring for attaching the load cell in a transmission housing. Axial support areas are provided on the fastening ring for axially supporting the outer ring of the first bearing. Moreover, measuring regions for receiving radial forces of the receiving sleeve are provided which connect the receiving sleeve with the fastening ring. Strain sensors are attached to at least two of the measuring regions. An evaluation electronics is connected to the strain sensors.

This work machine is provided with a clutch mechanism which is provided on a motive power transmission path between a drive source and a wheel. The clutch mechanism is provided with: a drive shaft with which drive force from the drive source is transmitted; a key member which is provided so as to be capable of moving relative to the drive shaft; a driven member which is driven by the drive shaft via the key member; an impelling member which impels the key member towards the driven member; and a ratchet holder which is provided with an engagement groove and a guide part, and which is provided so as to be capable of rotating coaxially with the drive shaft.

A rotorcraft having pusher propeller generated power during autorotations. The rotorcraft has an engine powered mode and an autorotation mode. The rotorcraft includes an engine and a drivetrain configured to receive torque and rotational energy from the engine in the engine powered mode. A main rotor system is coupled to the drivetrain and is rotatable to generate lift and forward thrust for the rotorcraft in the engine powered mode. A pusher propeller is coupled to the drivetrain and is rotatable to generate forward thrust for the rotorcraft in the engine powered mode. In the autorotation mode, the pusher propeller is aerodynamically driven responsive to airflow therethrough and the drivetrain is configured to receive torque and rotational energy from the pusher propeller, thereby providing power to the main rotor system.

A one-way clutch, including: a case; a drive plate enclosed by the case and defining openings; a first plate non-rotatably connected to the case and defining a first opening; a rotatable actuator plate; a strut including a central portion, an engagement portion, and a control portion; and a spring. In a locked mode: the spring pivots the engagement portion into an opening of the drive plate, a rotation of the drive plate in a first direction is enabled, and a rotation of the drive plate in a second direction is blocked. To transition from the locked mode to a free-wheel mode, in which the rotation of the drive plate in the second direction is enabled, the actuator plate is rotated by an actuator to contact the control portion and pivot the strut to displace the engagement portion out of the opening of the drive plate.

A one-way clutch, including: an outer race; an inner race; and a rocker assembly. The outer race includes: a first outer race plate defining a first rocker pocket; and a second outer race plate non-rotatably connected to the first outer race plate and defining a second rocker pocket. The inner race is axially disposed between the first and second outer race plates. The rocker assembly is at least partly disposed in the first and second rocker pockets and includes a rocker arranged to contact the inner race, a spring guide including a spring arm, and a spring wrapped around the spring arm and urging the rocker in a pivot direction. The one-way clutch includes: a first annular thrust washer axially disposed between the first outer race plate and the inner race; or a friction-reducing coating adhered to the first outer race plate and facing the inner race.

A dog clutch with ratcheting one-way clutch includes an axis, a dog clutch ring, a first ring, a second ring, and a plurality of rockers. The dog clutch ring has a plurality of first teeth. The first ring includes a plurality of second teeth, complementary to the first teeth, a first spline for receiving a first shaft, and a plurality of first pockets. The second ring includes a plurality of third teeth, complementary to the first teeth, a second spline for receiving a second shaft, and a plurality of second pockets. The plurality of rockers is disposed in a one of the plurality of first pockets or the plurality of second pockets for selectively engaging with the other one of the plurality of first pockets or the plurality of second pockets to prevent rotation of the first ring relative to the second ring in only one rotational direction.
