Abstract

486,491. Crank shafts. ARMSTRONG SIDDELEY MOTORS, Ltd., FELL, L. F. R., and TOWNS, H. L. Sept. 2, 1937, No. 23991. [Class 80 (ii)] [Also in Group XXV] In built-up crank shafts, particularly for large aircraft engines, and for use with solid big-ends, the crank pins are formed by two tubular portions 10, 11 each secured to a web and engaging one another through accurately machined radial V-teeth 12 developed from a point 13 on the crank pin axis. The two parts of the crank pin are held together by a bolt 17 with frustum-shaped head 19, the screw-threaded end of the bolt being engaged by a nut 20. This nut and the end of the bolt have a saw-cut 22 engaged by a strip 23 held in position by a bolt 25 which clamps a strip 26 one end 27 of which is bent up to engage the head of the bolt 25. The bolt is keyed to one of the crank pin portions by a cylindrical key 28 located by dowels 29. The tips of the teeth 12 of one portion are flattened to clear the roots of the teeth of the other portion, the spaces so formed being utilized to form channels for lubricant. This is circulated through channels 34 in the webs and grooves 31 in the periphery of the bolt.
