The present invention provides a clutch and a work machine having same. The clutch comprises an input member for receiving a driving force and rotating, an output member for outputting rotational motion, and at least one transmission member. The input member has at least one radially extending protrusion. The output member has at least one transmission engagement part. The transmission member is movable between a first position of engagement with the transmission engagement part and a second position of disengagement, being located in a path of rotation of the protrusion, and able to abut the protrusion and be driven to move to the first position. Displacement of the transmission member between the first position and second position has a radial component. According to the technical solution of the present invention, the function of automatically switching between transmission states according to the operating state of a prime mover can be achieved. The fact that displacement of the transmission member comprises a radial component helps to reduce the axial thickness of the clutch, so that the structure thereof is more compact.

An anti-reverse clutch apparatus includes an input shaft, which is rotated by rotation force supplied to the input shaft and which is provided with a push handle, which projects radially therefrom, an output shaft, which is mounted coaxially with the input shaft and is rotatable relative to the input shaft, a clutch housing including an internal gear formed along an internal circumferential surface of the clutch housing, and a locking block, which is mounted between the output shaft and the internal circumferential surface of the clutch housing, and rotatable together with the output shaft and which includes an external gear, which is formed along an external circumferential surface of the locking block to be engaged with the internal gear, the locking block being linearly moved in a radial direction of the output shaft by a sloped surface structure formed between the push handle and the locking block so that the external gear is engaged with or disengaged from the internal gear when the push handle is rotated.

An engine including an engine block having a cylinder defining a front of the engine, a blower housing coupled to the engine block and defining a hot half positioned adjacent the front of the engine and a cool half opposite the hot half, and an electric starter system positioned within the blower housing. The electric starting system includes a starter mount assembly coupled to the blower housing, an electric starter motor retained by the starter mount assembly and positioned in the cool half, and a battery mounted to the blower housing and positioned in the cool half. The battery is electrically coupled to the electric starter motor.

The invention relates to a laboratory centrifuge (1) with a coupling device (4) actuated by a centrifugal force. According to the invention an eccentric mass (22), especially a roller (23), is guided through a guideway (26) and preferably another guideway (27, 32) in such a way that the centrifugal force (46) of the eccentric mass (22) is deflected in such a way that a coupling force is generated which presses a coupling element (24) radially inwards against the outer surface of a drive shaft (3).

A clutch includes a first race, a second race, a pawl, a post, and a shoe. The second race defines a cam surface. The pawl is supported in the first race to pivot between an engaged position and a disengaged position such that contact between the cam surface and the pawl in the engaged position prevents relative rotation between the first and second races in at least one direction. The post is supported in the first race to slide between a first and a second position such that in the first position the post forces the pawl into the disengaged position. The shoe is configured to pivot with respect to the first race in response to a magnetic field to slide the post into the second position.

A transmission clutch module includes an inner race, an outer race, and a plurality of race engaging pawls adapted to selectively secure the races together in either a locked position or an unlocked position. The clutch module includes 5 an actuator cam configured to be moved between two angularly spaced positions to control the pawls. The inner race is comprised of two axially spaced inner race plates axially secured together by rivets for retaining, and accommodating angular limited movements of the pawls. The pawls are circumferentially disposed about the inner race plates, and are radially outwardly biased by springs 10 to engage the outer race, unless blocked by the actuator cam. The pawls are weighted at one end, so that at a threshold speed of the inner race, they can overcome spring resistance to disengage from both the actuator cam and the outer race.

A fall-protection apparatus with a drum and a rotationally-activated braking device including at least one velocity-actuated pawl that is mounted on a pawl-support plate that is rotatable relative to the drum through a predetermined range between a first position and a second position. The pawl-support plate is rotatable relative to the drum from the first position to the second position upon the pawl-support plate experiencing a rotational acceleration that is above a predetermined threshold value of rotational acceleration. When the pawl-support plate is in the second position, the velocity-actuated pawl can be actuated by a rotational velocity that is lower than a rotational velocity required to actuate the pawl when the pawl-support plate is in the first position.
