Abstract
A vane mounting angle adjusting mechanism comprises an angle adjusting rod connected with a water pump vane and a box connected with a water pump. Wherein, an external end of the angle adjusting rod is extended into the box and connected with a lifting bearing pedestal. The lifting bearing pedestal is connected with a worm and wheel drive mechanism. A drive hand-wheel is arranged on a worm. The drive hand-wheel is rotated. Thus, the drive is transmitted to the lifting bearing pedestal through the worm and wheel drive mechanism with a large transmission ratio. The lifting bearing pedestal drives the angle adjusting rod to move axially and realize vane mounting angle adjustment. A thrust bearing in the lifting bearing pedestal bears an axial drawing force generated by a hydraulic torque of the vane towards the angle adjusting rod. The utility model transmits the drive on the drive hand-wheel to the lifting bearing pedestal through the worm and wheel drive mechanism with a large transmission ratio. The lifting bearing pedestal drives the angle adjusting rod to axially move and realize vane mounting angle adjustment, thus ensuring simple structure and easy processing and assembling.
