[Also in Division G1] A rotary transmission dynamometer comprises an epicyclic gear system within a gear housing 1 and includes planet wheels 11 meshing with an annular gear 13 by means of helical teeth, in which the gear 13 constitutes a reaction member held within a coaxial tubular casing 14 against rotational and axial movement relative to the casing 14 whilst having a limited degree of radial float therein, the casing 14 being in sliding, substantially fluid tight engagement with inner circumferential surfaces 1A and 1B of the gear housing 1 and being held from rotation relative to the housing 1 whereby, during transmission of torque, the casing 14 tends to move axially against the restraint of hydraulic liquid in a chamber 21 and the liquid pressure is varied to counterbalance the torque by axial movement of a member 18 moving with the casing 14 and acting as a piston in the chamber 21 and the torque is indicated by measuring apparatus responsive to the liquid pressure. The liquid pressure in the chamber 21 is increased (or decreased) by the movement of the piston 18 to the right (or left) to increase (or decrease) the communication of the chamber 21 with a source of pressure 23 through a passage 22 in a portion 19 of the piston 18 which slides fluid tight on a fixed member 20. Rotation of the gear 13 is prevented by tangential links (25) (Figs. 2, 3, not shown) connected by ball-and-socket joints to lugs (28, 29) on the casing 14 and housing 1. Several pairs of directly connected coaxial planet wheels 10, 11 may be used, the wheels 10 and a sun wheel 4 with which they mesh may have straight or helical teeth, the latter imposing an axial load in the opposite direction to that imposed by the wheels 11. Even distribution of the loads transmitted by the sun wheel 4 to the several planet wheels and by the several planet, wheels to the annular gear 13 is ensured by the radial play allowed by the respective splines 6 and 16.
