DRIVING DEVICE FOR TURBINE SHAFTING ROTATION AND TURBINE-GENERATOR SET Russian patent published in 2015 - IPC F01D25/34 F01D25/36 

FIELD: machine building.

SUBSTANCE: driving device for the rotation of a turbine shafting of a turbine-generator set. The driving device comprises a main shaft rotating reducer with electric drive and an auxiliary shaft rotating mechanism (5) with hydraulic drive. The auxiliary shaft rotating mechanism (5) can be controlled by a stem of a double-acting hydraulic cylinder (6). The auxiliary shaft rotating mechanism (5) comprises a wheel made solid with the shafting (1), and a pusher 98) connected to the cylinder (6) stem. The pusher (8) can be engaged with engagement units (11) set on the wheel periphery and can move between the retracted position when it is disconnected from the wheel and the engaged position when it is engaged with one of the engagement units (11) and when the projecting cylinder (6) stem turns the wheel. The pusher (8) is connected to the cylinder (6) stem by a hinge joint resting against a slider made solid with the cylinder (6) stem so that the pusher can swing between the above retracted position and the engaged position. At cylinder (6) stem movement the slider is moved translatory by guiding units supported by a plate (14) made solid with the cylinder (6).

EFFECT: more accurate linear movement of a pusher and shaft rotation.
