Torque-limiting interfaces having a plurality of undulations arranged around an axial bore or drive socket and separated by a plurality of transition regions, with each undulation having an upslope, a peak, and a downslope. The torque-limiting interfaces are configured to engage and disengage to provide torque transmission with predetermined torque limits at various rotational speeds and for amounts of actuations while remaining within a specified operational range.

A recording material feeding device includes a stacking portion, a driving source, a holding member, a torque limiter for limiting transmission of a driving torque from the driving source to the stacking portion in a case that the driving source rotates in a state in which the holding member holds the position of the stacking portion; a storing portion for storing information on a holding state of the holding member; and a controller for controlling the driving source to rotate at a rotational speed slower when the information is information indicating that the holding member holds the position of the stacking portion than when the information is information indicating that the holding member does not hold the position of the stacking portion.

A torque limiting apparatus is provided having an input shaft, an output shaft, a housing, a spring, and a length adjustable shank and collar assembly. The input shaft communicates with a rotating end segment having a cam surface. The output shaft communicates with a rotating end segment having a complementary cam surface for engaging with the cam surface of the input shaft. The cam surfaces cooperate to generate separation forces between the respective rotating end segments. The housing encases the first end segment and the second end segment. The spring is supported in the housing, and is configured to oppose the separation forces generated by the cam surfaces, and is configured to urge together the first end segment and the second end segment to remain in rotating coupled engagement. The length adjustable shank and collar assembly is provided between the spring and the housing and is configured to adjust compressive force on the spring to change torque output of the apparatus. A method is also provided.

A clutch device includes: an input disk; an output disk; and a biasing member configured to press the input disk and the output disk against each other, the input disk and the output disk contact or separate from each other in an axial direction, and at opposing surfaces thereof, respectively have tooth portions engageable with or disengageable from each other, at each tooth portion, recessed and raised portions extending in a radial direction are alternately provided in a circumferential direction, each of the recessed and raised portions is formed so that a width in the circumferential direction may outwardly expands in the radial direction, and engagement force in the axial direction is greater on an inside of the tooth portions in the radial direction than on the outside when the tooth portions of the input disk and the output disk pressed by the biasing member are fitted in each other.

A control device for a vehicle is provided. The control device includes an electronic control unit that is configured to: exert the torque of an input member on a fixed member and a rotating member such that the fixed member and the rotating member are separated from each other, when the thrust is exerted for making the engagement teeth mesh with each other; estimate an inclination angle of tooth surfaces based on a relative movement amount between the fixed member and the rotating member, and a relative rotational amount between the fixed member and the rotating member; estimate a frictional coefficient of the tooth surfaces based on the inclination angle; and control the thrust of the actuator according to the frictional coefficient.

A cam-type damper 118 includes a drive cam 131 provided on a clutch shaft 114 without capability of relative rotation and a driven cam 132 provided on a main shaft 103 without capability of relative rotation. The clutch shaft 114 contains a shaft end of the main shaft 103 and the main shaft 103 is rotatably supported on the inner circumferential surface of the clutch shaft 114. The driven cam 132 provided on the main shaft 103 is disposed between a front end surface 114g of the clutch shaft 114 and a rear end surface 103h of a main shaft gear 103d provided on the main shaft 103 and the movement of the driven cam 132 in the axial direction is restricted.

An apparatus for transfer of a torque from an internal combustion engine to an auxiliary unit has an auxiliary unit shaft and a pulley rotatably disposed on the auxiliary unit housing. The pulley and the auxiliary unit shaft are connected with one another by an overload protection device configured to interrupt the connection between the pulley and the auxiliary unit shaft if a predetermined torque is exceeded. The overload protection device has a spring washer having multiple spring arms connected, on the end side, with connection elements of a disk-shaped driver until the predetermined torque is reached. Each connection element is configured as a pocket-shaped mounting in the driver, wherein the respective spring arm end lies against a contact surface of the pocket-shaped mounting under spring tension, with force fit. The respective pocket-shaped mounting is configured as a hook-shaped crosspiece cut out of the driver in certain regions.

A compact clutch including a driven shaft on which the following are mounted: a gear wheel; a driving bush; a driven bush; a coil spring; a first collar with cam surfaces; and a second collar with cam surfaces. The gear wheel and the bushes are arranged axially next to each other; the gear wheel and the driving bush are constrained together in the circumferential direction; the spring surrounds externally the bushes; the first collar surrounds externally the spring; and the second collar surrounds externally the first collar. The gear wheel and the bushes are constrained to the driven shaft in the axial direction by means of two stop rings; and the driven bush is constrained to the driven shaft in the circumferential direction by means of at least one tongue.

A clutch tool includes a housing that is non-rotatable with respect to the first section of the work string and comprising inner grooves. The clutch tool also includes an inner mandrel that is non-rotatable with respect to the second section of the work string. The inner mandrel includes outer grooves that extend along only an axial portion of the inner mandrel. Further, the inner mandrel includes a torque transition area opening from the outer grooves and extending completely around the inner mandrel.
