20090301836 | TORQUE LIMITING MECHANISM - An intended object of the present invention is to realize a high-precision torque limiting mechanism capable of limiting an output torque to a magnitude of not more than a prescribed value, as well as to reduce a frictional torque produced upon occurrence of a slip. To accomplish this object, a ball ramp section 13 is attached to a slip clutch section 3 for reducing friction between friction plates 31 and 32 forming the slip clutch section 3 and limiting a torque to be transmitted by utilizing an axial thrust produced at the ball ramp section 13 in accordance with the magnitude of an input torque. The precision with which the torque to be transmitted is limited is enhanced by making improvements to the shape of an internal side surface of a recess G formed in each of cam elements 131 and 132 of the ball ramp section 13. | 12-10-2009 |

20100213022 | Clutch structure for manual hoists - A clutch structure for manual hoists includes a driven wheel for driving the wind device in the manual hoist. A ratchet and at least one resilient member are sequentially and co-axially mounted on the driven wheel. A nut is screwed onto the driven wheel to prevent the ratchet and the at least one resilient member from detaching from the driven wheel. The at least one resilient member axially pushes the ratchet to make the ratchet securely abut the driven wheel, and enhance the friction between the ratchet and the driven wheel, wherein the connecting intensity is the load limit of the manual hoist. The push force from the at least one resilient member to the ratchet is adjusted, and the friction between the ratchet and the driven wheel is adjusted when the position of the nut is adjusted. | 08-26-2010 |
20110024253 | Torque Limiting Driveline - A torque-limiting device assembly is provided that includes a bell having a top wall and a circumferential side wall defining a bell interior. A plurality of radially-arrayed engagement grooves are formed on an inner surface of the top wall. A clutch stub shaft having a stem and a plurality of engagement protrusions formed on a clutch flange is disposed within the bell interior. A resilient member is secured to the bell, and the resilient member biases the clutch stub shaft towards the top wall of the bell such that the engagement grooves frictionally engage the engagement protrusions to transfer torque from the stem to the bell when the stem is rotated. An input torque applied to the stem that is greater than a predetermined input torque causes the engagement protrusions to disengage from the engagement grooves such that the input torque is not transferred from the stem to the bell. | 02-03-2011 |
20110139566 | FEEDBACK TORQUE LIMITER - A feedback torque limiter device for an actuator having an input shaft, output shaft and gear reduction for transmitting torque from the input shaft to the output shaft comprises an output torque sensor, and input torque limiter and a feedback mechanism. The output torque sensor senses actuator output torque downstream from an actuator gear reduction. The input torque limiter grounds additional torque from the input shaft when engaged. The feedback mechanism engages the input torque limiter when the output torque sensed by the output torque sensor reaches a predetermined value. | 06-16-2011 |
