Abstract
1,233,642. Toothed gearing. E. SCHEUBECK. 22 April, 1969 [26 April, 1968], No. 20528/69. Heading F2Q. [Also in Division H1] A tap changer having a diverter switch and a tap selector, and generally of the type described in Specification 1,197,379, comprises for its tap selector mechanism a Maltese-cross wheel 21, two drive-rings 31, 32 and two selector contacts 14, 15 coupled to the drive rings one each respectively. The selector contacts traverse circumferentially spaced tap contacts 4, 5 &c. in a sequence; to this end, the two drive rings are rotated alternately by one sector (i.e. the angular distance between contacts 4 and 5) by a roller pin 24 which is engaged movably in a radial slot 25 of the wheel 21, which in turn is driven by a wheel 22. The selector mechanism includes a disc 27 mounted below the Maltesecross wheel on a common shaft, and having peripheral cam formations 272. The roller 24 is actuated by the disc 27 from one of the drivering grooves 35 radially outwards against the bias of a spring 26 to engage in one of the grooves 34 of the second drive ring to rotate the latter. Electrical leads 18, 19 provide connections to the selector contacts 14, 15 through ring members 16, 17, respectively. An idle motion of the disc 27 provided by a snug 30 in groove 29 may be used to maintain the tapping sequence on reverse rotation as actuated by a member 45.
