Abstract: A rotational coupling includes input and output hubs disposed about a rotational axis and an attachment ring disposed about the axis on one side of the input hub opposite the output hub. A flexible, multi-coil body such as a cable is disposed radially outwardly of the input and output hubs and couples the hubs together for rotation upon rotation of the input hub in one rotational direction. The body has ends coupled to the output hub and attachment ring. A torque limiter includes a torque transmission plate configured to rotate with the input hub and an armature plate fixed against rotation. The torque transmission plate and armature plate are configured to move axially together along the axis of rotation. An electromagnet disposed on one side of the torque limiter opposite the input hub attracts the plates in a second axial direction away from the attachment ring when energized.

Abstract: A compact clutch which comprises 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 clutch is characterized in that the gear wheel and the bushes are constrained to the driven shaft in the axial direction by means of two stop rings; in that the driven bush is constrained to the driven shaft in the circumferential direction by means of at least one tongue; and in that the tongue ensures engagement between the driven bush and the driven shaft in the circumferential direction, while in the axial direction the driven bush may slide with respect to the driven shaft.

Abstract: A transmission device for two or more shafts is provided having two first cylindrical sleeves which are connected to the first shaft and can be mechanically coupled or uncoupled with two second cylindrical sleeves connected to the second shaft or to a third shaft aligned with the second shaft, by tightening or loosening, respectively, two helical springs arranged in a substantially coaxial manner astride these cylindrical sleeves. Two control collars are mechanically coupled with two tubular members, so that the mutual translation of the control collars with respect to the tubular members also causes their mutual rotation, the ends of the helical springs being arranged into seats made in the control collars and in the tubular members so that their mutual rotation tightens or loosens the coils of the helical springs, thereby causing the coupling or the uncoupling, respectively, between the first cylindrical sleeves and the second cylindrical sleeves.

Abstract: A self-adjusting wrap spring clutch has a spring overlying driving and driven arbors and in engagement with each. One end of the spring is loosely connected to a control collar, which surrounds the spring and at least a portion of each of the arbors, while its other end is connected to the driven arbor. The control collar is held against rotation by a spring biased pawl engaging one of a plurality of preferably equiangularly spaced teeth on its circumference. When a solenoid is energized, the pawl is withdrawn from the tooth on the control collar and the spring tightens on the driving arbor to transmit torque to the driven arbor from the driving arbor. The pawl rides on a cam surface on a gear hub, which rotates whenever the driven arbor rotates, until the pawl falls into an opening or low dwell in the cam surface so that the pawl can engage one of the teeth on the control collar. Since the solenoid is deenergized shortly after energization, the pawl's engagement with the tooth stops rotation of the control collar to stop rotation of the driven arbor through holding the end of the spring so that it can no longer transmit torque to the driven arbor from the driving arbor.

Abstract: A solenoid for controlling the engagement and disengagement of a wrap spring clutch includes an electromagnetic coil having a core member disposed adjacent one axial end thereof. An armature is provided within the electromagnetic coil for selective axial movement in response to the energization and deenergization of the electromagnetic coil. The armature is connected to an actuator for the wrap spring clutch such that movement of the armature controls the engagement and disengagement thereof. The core member and the armature are both formed from relatively soft, magnetically permeable materials. A flux breaker is disposed within the electromagnetic coil between one axial end of the armature and the core member. The flux breaker is formed from a relatively hard, non-magnetically permeable material, such as stainless steel. The flux breaker prevents the armature from contacting the core member when attracted thereto by energization of the electromagnetic coil. The flux breaker is provided for minimizing the adverse effects of residual magnetism on the operation of a solenoid. By forming the flux breaker from a material which is harder than the materials used to form the core member and the armature, the useful life of the flux breaker is extended beyond that of prior art flux breakers.

Abstract: A two speed transmission including a direct drive and a reduced speed ratio. The transmission is directly coupled to a variable speed engine crankshaft and includes pulleys thereon for the driving of auxiliary engine equipment. A first drive train includes planetary gearing and a one-way clutch while direct drive is provided by a wrap spring coupling cylindrical surfaces on the transmission input and transmission output axially adjacent and coterminous. The wrap spring includes an element having a flat side for engagement of the cylindrical surfaces. Two actuator mechanisms are illustrated employing centrifugal weights to result in advancement of one end of the wrap spring to tighten same into coupling engagements at low engine speeds. At higher engine speeds, the actuator mechanism releases the wrap spring from the cylindrical surfaces for drive through the planetary gearing.

Abstract: The unitary spring clutch and actuator assembly has a spring clutch subassembly comprising a shaft for supporting two axially spaced input and output drums which are surrounded by a helically wound spring, one end of which is connected to a control sleeve or collar surrounding the spring. The collar has a stop element which coacts with the actuator subassembly to control rotation of the collar and hence engagement or disengagement of the spring from the input and output drums. The actuator subassembly includes a fixed frame for supporting an electro-magnetic control device which is adapted to engage and disengage from the stop element. The spring clutch and actuator subassemblies are secured together at one end portion of the shaft, which projects through an opening in the frame, and by a retaining member constructed and arranged to engage the tubular shaft and frame. A bearing is interposed between the shaft and frame to facilitate rotation of the shaft relative to the fixed frame.

Abstract: A coil spring clutch is disclosed incorporating a resilient radially cylindrical member on which the coil spring bears. The torque transmitted by the spring urges the yieldable member to contract so that the clutch will slip at a constant predetermined value of the torque. The yieldable member contracts as a result of the major tensile stresses in the helical spring, making the slip torque substantially independent of large variations in the coefficient of friction of the clutch elements. Also disclosed are means for adjusting the clutch for varying the slip torque.
