Turning gear for steam turbine generator unit

The utility model discloses a turning gear for a steam turbine generator unit. The turning gear particularly relates to the turning generating set for the steam turbine generator unit. The utility model solves the problems that because a journal bearing and a thrust bearing arranged in the existing turning gear for the steam turbine generator unit in China have low bearing capability and weak self-lubricating capability, and are extremely easy to be worn, gears and a worm gear and a worm are worn with each other due to the reduced center distance there between. The turning gear is assembled with 8 rolling bearings with different models and 2 single-row needle bearings, and a motor (6) transfers power to a swing plate component (7) via a worm (5), a turbine shaft component (1), an output gear shaft component (2), a first intermediate gear shaft component (3) and a second intermediate gear shaft component (4). The utility model is used for starting the steam turbine generator unit at any time and checking whether the steam turbine generator unit is under the normal working condition.
