| To DA.{Bernard Day - Chassis Design} from E: Contd. -3- E2/G2.9.19. replaced by a plain diameter tapering up to the universal teeth so that the oil delivered sideways by the ball bearing in the gear box will run along the plain diameter and be fed by the taper in-to the universal-see Sketch - This oil is prevented from escaping into the torque tube proper by means of a course oil retaining thread on the outside of the female portion of the universal. As this thread will be directly opposite to the universal, it occupies the best position for being concentric. The thread operates inside an aluminium partition secured in some suitable manner within the flanged front piece of the torque tube. Drain holes should be provided to retransfer the oil to the gear box, these drain holes being lower than those shewn, if possible, on the scheme of the gear box LEC.1043. Regarding the aluminium partition, Mr. Royce thinks this should be a die casting, and that it might be fixed by riveting into the taper bore of the torque tube, as in sketch above. Would you kindly submit a new scheme embodying the foregoing points. E.{Mr Elliott - Chief Engineer} | ||
