Water pump blade angle is at labour adjusting device based on poor drive of tooth

The utility model belongs to the technical field of fluid machinery, a poor driving mechanical type water pump blade angle adjusting device of tooth is related to, its characteristic lies in: adopt the poor drive principle of tooth to innovate the structure and the overall arrangement of adjusting nut and adjusting screw pair, realized that the water pump blade meets that the water angle of attackdoes not shut down in real time in the labour regulation and control. Adopt the common location of load cage and adjusting device body and centre gripping adjusting nut's load mode, improved the support rigidity of parts by a wide margin and shortened loading force's bang path, effectively strengthened device and resisted the water pump and lift an ability of impact, avoid the blade that falls traditional mechanical adjusting device and adjust special motor, simplified by a wide margin and optimized the control element of device, adopt the layout scheme who unifies wherein centre clutch more,reduced key component's q
