GEAR PUMP WITH REDUCTION GEAR Russian patent published in 2003 - IPC

FIELD: mechanical engineering; pumps. SUBSTANCE: invention relates to gear pumps designed for delivery of liquids. Locking clutch of pump is rigidly secured on support flange ring lip is installed on nearest to support flange end face of carrier rigidly connected with output end of drive gear shaft. End part of lip is fitted in hole of support flange. Through ring groove is made from inner side of lip to communicate space in end face of drive gear bearing from side of output end of shaft with system of lubricating holes of reduction gear. Lip is sealed by floating ring over outer diameter, sealing ring being secured on support flange inside clutch. Spaces are made in end faces of sliding bearings of drive and driven gears. Hole made in driven gear communicates spaces in end faces of drive gear bearings. Hole is made in bearing of driven gear and bearing of drive gear communicating spaces of these bearings. Through hole is made in support flange in area of bearing space of driven gear. EFFECT: improved reliability and provision of self-contained operation of high-speed compressors and turbine engines. 4 dwg
