摘要： According to one aspect, a releasable roller clutch includes a shaft and a clutch housing positioned around the shaft. The shaft and clutch housing together defining a space there between with rollers positioned in said space. The rollers permit rotation of the shaft relative to the clutch housing when in an unlocked position in which the rollers are not wedged and prevent rotation of the shaft relative to the clutch housing when in a locked position in which the rollers are wedged. A cage extends into the space defined between the shaft and clutch housing. The cage is moveable relative to the clutch housing between an unlocking position and a locking position. The cage has a contact edge positionable to prevent the rollers from moving from the unlocked position to the locked position when the cage is in an unlocking position. The releasable roller clutch permits rotation of the shaft relative to the clutch housing in both directions when the cage is in the unlocking position.

摘要： A bistable pitch propeller includes a ball, a spring, and a clutch module where the clutch module has a range of rotational movement between a locked end position and a released end position. The clutch module includes a detent, where the ball sits inside and outside of the detent when the clutch module is in the locked end position and released end position, respectively. In response to an input torque and a spring force from the spring, the clutch module rotates toward the released end position and the locked end position, respectively. The bistable pitch propeller also includes an aircraft blade where the aircraft blade is at the first pitch angle and the second pitch angle when the clutch module is in the locked end position and the released end position, respectively.

摘要： A traction drive system for an articulated robotic arm. The traction drive system can include an input drive disk, a spider, an array of traction balls, a traction plate, an output drive shaft, a clamping device to load the traction balls, and an absolute rotation position sensor system. The rotation of the output drive shaft can be coupled to the rotation of the input drive disk while the traction balls are frictionally engaged to the drive disk surface and traction plate surface. The rotational connection can be decoupled when the traction balls are not frictionally engaged to the drive disk surface and traction plate surface. A rotational position sensor located in proximity to the traction drive can provide absolute rotational position feedback of the output drive shaft.

摘要： A torque limiter comprising: a ramp roller, said ramp roller comprising: an input ramp roller element arranged to be driven by an input torque and having a first ramp surface; an output ramp roller element arranged to drive an output torque shaft and having a second ramp surface; ramp roller balls disposed between the first ramp surface and the second ramp surface; wherein said output ramp roller element is axially and resiliently compressible and wherein an overtorque condition causes axial compression of said output ramp roller element. This arrangement removes all axially sliding friction surfaces from the torque limiter so that the torque bandwidth is reduced, allowing manufacturers to design structures more optimally.

摘要： A planetary gear system with a sun gear, a ring gear co-axial with the sun gear, at least one planetary gear meshing with both the sun gear and the ring gear, and a planetary gear carrier which rotationally supports the at least one planetary gear. A torque clutch is supported by and connected directly between two of the sun gear, the ring gear, the at least one planetary gear and the planetary gear carrier. The torque clutch prevents relative rotation when an acting torque is below a predetermined torque value and allows relative rotation when the acting torque is above the predetermined torque value. A torque threshold adjustment mechanism is provided for adjusting the predetermined value of the torque at which the torque clutch slips.

摘要： An integrated torque limiter/no-back device for use in an actuator with an input shaft, an output and gear reduction. The device includes an input ramp to receive torque from the input shaft; a combined ramp to transfer torque; an output ramp to transfer torque to the gear reduction; one or more balls between the input ramp and the combined ramp and between the combined ramp and the output ramp to transfer torque; and a brake for causing torque to be grounded and for preventing backdriving of the input shaft by preventing movement of one or more of the input ramp, the combined ramp and the output ramp when a torque threshold has been met. The input ramp and the output ramp are a no-back ramp and a torque limiter ramp, respectively, and the device also includes a pin between the combined ramp and one or more of the no-back ramp and the gear reduction for transferring torque.

摘要： A vehicle includes a transmission, which is characterized by the absence of a friction clutch that is operable to limit torque transfer between the drive wheels and a shaft of the transmission, to prevent torque communication between the drive wheel and the shaft. The transmission includes a selectable one way clutch, which interconnects a housing of the transmission and the shaft. The selectable one way clutch is selectively operable to prevent rotation of the shaft in at least one rotational direction. The selectable one way clutch includes a torque limiting system, such as a ball-detent torque limiting mechanism, which is operable to prevent torque transfer greater than a pre-defined value, between the housing and the shaft.
