Abstract
193,381. Schein, A. E. Feb. 20, 1922, [Convention date]. Brasses; spring supports; cylindrical bearings; vehicle-axle bearings; thrust bearings.- Bearings are lined with a material of low modulus of elasticity such as Babbitt metal, the thickness of which is proportioned so that a wedgeshape film of oil will be produced and maintained between the bearing surfaces. As shown in Fig. 1, applied to a thrust-bearing, a collar 2 on a vertical shaft bears on a lining 4 of Babbitt metal carried on a non-rotatable block 5 which is supported resiliently by springs 7. The block 5, Fig. 7, has a saw-like, upper face 9 so that the thickness of the. metal fitted thereon diminishes in the direction of rotation of the shaft. The lining may be in one sheet or composed of a number of blocks and the thicker parts of the lining may be tapered as at 14<1> and provided with radial grooves 14. When the shaft rotates in the direction of the arrow 15, a wedge-shape film of oil is drawn between the Babbitt metal and the shaft collar 2 due to the radial compression of the metal at any point being proportional to its thickness. Lubricant, circulated by a pump driven from the shaft 8, passes through a passage 53 and a central passage 54 into the grooves 14 and to the bearing surfaces. It. then collects into an annular space 55 surrounded by a ring 56 with baffles 57, passes over the edge of the ring 56 into an, annular space 57<1> and through the opening 58 to the pump. The springs 7 may be replaced bv a disc of elastic material such as cork or felt. As applied to a journal bearing, especially for gyroscopic rotors, the lining of Babbitt metal may be in four quadrants, the centre of curvature of the bearing surface of each quadrant being slightly to one side of the axis of the shaft so that the shaft may bear on a 90‹ sector no matter in what direction the load is applied. Axial passages formed between the blocks for the passage of lubricant preferably have the central portion offset. As applied to an axle box, Fig. 9, blocks 44, 45, are fitted in a brass 40 so that their thickness diminishes towards the top of the shaft. The brass 40 has members 41 normally clear of the shaft which are brought into action in resisting the lateral thrust of the brake shoes.
