ADJUSTING DEVICE FOR A TURBINE

摘要

The invention relates to an adjusting device for a turbine, wherein said turbine is designed with a rotatable hub and turbine blades which are disposed on the hub and are displaceable about their longitudinal axis by means of the adjusting device. The turbine blades comprise in each case a base area lodged into the hub, on which the adjusting device engages. The adjusting device is designed in such a way that each base area of the turbine blades carries a first bevel gear. The first bevel gears engage with each other with the interconnection of at least a second bevel gear, whereby a bevel gear transmission is formed. A controllable rotary drive is provided for driving at least one of the bevel gears.
