A planetary carrier includes a journal bearing for supporting a planetary gear. The journal bearing receives lubricant to produce a lubricant film to support gear loads. A torque frame is attached to the carrier housing to transmit torque and to prevent twisting of the carrier housing. The torque frame includes several lubricant communication passages to provide lubricant to each of the separate journal bearings. Each of the lubricant communication passages includes an accumulator for storing lubricant during normal operation. The accumulator stores a desired amount of lubricant to provide lubricant to the adjacent journal bearing for the interim period between primary system stoppage and reestablishment of lubricant flow by a secondary system.
A planetary gear train assembly comprising:
A torque frame assembly for a planetary gear housing comprising:
A method of supplying lubricant to gears of a planetary gear system during a time period between failure of a primary lubricant supply and reestablishment of lubricant flow, said method comprising the steps of:
