A continuously variable-ratio friction gear comprises an input shaft 6 which drives through bevel wheels 7, 30, friction discs 12 axially splined in the bevels 30 and spring-biased radially inward in frictional engagement with a roller 11 comprising a number of contiguous elements 45 formed as curved solids of revolution, the common envelope of which is circular, the elements 45 being arranged to form a ring- like articulated roller around a driven rotor 19 splined for axial movement on an output shaft 8, the radius of curvature of the generatrices of the elements 45 being constant throughout the whole of their length and equal to the radius of their common circular envelope, each of said elements having an ogived end and a truncated end forming seating surfaces, the arrangement being such that by manually or servo turning a pinion 17 engaging rack teeth 18 on the driven rotor 19, the rotor is axially moved in either direction, rolling the elements 45 from the central neutral position on the friction discs 12 to effect a forward or reverse output drive. To prevent unnecessary wear in the neutral position, central hollows 60 are provided in the friction discs 12 to avoid contact with the roller elements 45. The rotor 19 comprises two parts 38, 39 spigoted together at 40 and rotationally connected by shear pins 41, each part being formed with tongues 43, 44 arranged opposite one another to form split bearings having bearing shells or bushes in which the elements 45 are carried. The elements 45 are at least one greater in number than the number of friction discs 12 to ensure that no one element shall at any time contact two friction discs. The friction discs are loaded inwards by Belleville washers 34 adjustable by screwed plugs 21, and acting through a beaded seating 36 located in a small register in the centre of the shafts 25. The friction plates 12 may be slightly conical such that as the roller 11 is displaced towards the centre, the pressure of the springs 34 increases enabling a higher torque to be transmitted in the lower speed range of the output shaft 8.

Abstract: 962,126. Fluid-pressure servomotor systems. H. M. HOBSON Ltd. Jan. 16, 1963 [Dec. 14, 1961], No. 44928/61. Heading G3P. [Also in Division H2] A servo actuator has at least two rotary output members whose displacements bear differing relationships to the deflection of an input member. As shown in Fig. 1 a floating lever input member 2 is pivotally connected with tandem valves 3 controlling tandem servo-pistons 4 which have a connection 16 with the lever and, by their axial movements, impart rotation to two output members 7, 8 through ball screw mechanisms 20, 21. The rotation of the member 7 bears a linear relationship to the displacement of the servo-pistons but the rotation of the member 8 bears a variable relationship due to the interposition of a roller 12 coacting with a cam slot 13 so that it turns a nut 9, threaded into the end of the servo-pistons, as the latter are displaced. In another embodiment, the input member operates a single valve 3A, Fig. 6, controlling a single servo-piston 4A which imparts rotation to an output member 7, applies feedback to the input member, and moves a roller 23 in a cam slot 24 in a nut 25 so as to turn the nut which, due to a cam slot and roller connection 27 with a second valve 3B, results in operation of a second servo-piston with consequent rotation of a second output member 8 until the valve 3B is returned to neutral by the action of the threaded engagement between the nut 25 and the output member. A third output member may be rotated by a third servopiston controlled by the valve 3B or by an additional valve actuated from the servo-piston 4A through apparatus similar to the rollers 23, 27 &c. and nut 25.
