SUPPORT ASSEMBLY OF TURBOMACHINE REDUCER SYSTEM AND METHOD OF REDUCER SYSTEM SUPPORT IN TURBOMACHINE Russian patent published in 2018 - IPC F01D21/04 F02C7/20 

FIELD: machine engineering.

SUBSTANCE: support assembly of reducer system of the turbomachine comprises a support having a more compliant portion and a less compliant portion. The less compliant part contains a stop limiting the axial movement of the reducer system in the turbomachine. The stop is configured for placement at a distance from the rigid element during the normal operation of the turbomachine comprising said reduction system, and contacting said rigid element during abnormal situation with limitation of axial movement. During operation of the turbomachine, the more compliant part allows certain movement of the reducer system relative to other parts of the turbomachine. When the reducer system is supported in the turbomachine, the more compliant portion is used to allow reducer gear system to move relative to the other parts of the turbomachine, and the less compliant portion is used with the stop for limiting movement of the reducer system in axial direction.

EFFECT: group of inventions makes it possible to provide adaptation of the reducer system of the turbomachine to the tolerances of the support assembly and deformation of the turbomachine during its operation, and elimination of abnormal movement of reducer system in axial direction.
