Abstract

129,424. Baumann, K., and British Westinghouse Electric & Manufacturing Co. July 8, 1918. Toothed gearing. - For alining toothed gearing and for distributing the tooth pressure, bearings for the shafts of the toothed wheels are cushioned and adjusted by films of oil or other liquid maintained between the bearing and its supports by a continuous flow of liquid between the parts. Clearance spaces 16, 17, Fig. 1, below and above a bearing have inlets 18, 19 and outlets 22, 23, and oil is forced through the spaces by a pump or two separate pumps which are provided with throttle or relief valves, so that by varying the oil pressure the bearing may be adjusted vertically. In a modification, the spaces 16, 17 communicate, and the bearing is cushioned by films at the sides as well as at the top and bottom. As shown in Fig. 4, a number of parallel clearance spaces 49, 50 may be employed. The clearance spaces may be of varying width as shown at 55, Fig. 7. Stops may be provided to prevent the bearing from dropping to such an extent as to close the clearance space. Instead of using a pump, a supply of oil under pressure may be tapped from the oil film of the journal.
