| x237. To By.{R.W. Bailey - Chief Engineer} from Da.{Bernard Day - Chassis Design} Rm{William Robotham - Chief Engineer} c. For H.{Arthur M. Hanbury - Head Complaints} Hs.{Lord Ernest Hives - Chair} DA.{Bernard Day - Chassis Design}1/HP.19.9.33. Needle Bearing Universal Joints. Bensport Propeller shaft. Herewith is N. Sch. 3827 shewing the adaptation of needle bearings to the standard mechanics joints on the propeller shaft. It follows closely EX.10701. The rollers are intended to be assembled by sticking them with grease, the trunnion pins being kept solid. Should there be any disadvantage in this, we can provide retaining lips on the lines of Ransome and Marles patent, but as this involves detachable ends to the trunnion pins, and may affect the location of the outer casing, it seems best to keep the pins solid for the moment. The stress in the pins at the bottom of the roller recess is about 20% higher than at the point where the pin enters the fork forging, but is still not very high. It seems better to keep up the strength and stiffness of the trunnion bearing piece, so the bore of that is practically unaltered. DA.{Bernard Day - Chassis Design} | ||
