Abstract
The invention relates to a spring assistance type pipeline necking adjusting device in the technical field of mechanical design. The spring assistance type pipeline necking adjusting device comprises a control body, a centrifugal shaft, centrifugal cavities, centrifugal bodies, centrifugal springs, arc plates, an elastic band and extension springs. The centrifugal cavities, the centrifugal bodies, the centrifugal springs, the arc plates and the elastic band are all arranged in the control body. One end of each centrifugal body is arranged in the corresponding centrifugal cavity and connected with the centrifugal shaft through the corresponding centrifugal spring, and the other end of each centrifugal body is of an arc structure and is in sealing contact with the corresponding arc plate. The elastic band is arranged on the outer surfaces of the arc plates. When the rotating speed of an engine is high, a moving body moves upwards, necking of an air inlet branch pipe becomes large, and the pumping loss is small. When the rotating speed of the engine is low, the moving body descends, necking of the air inlet branch pipe becomes small, and the tumble ratio becomes large. The spring assistance type pipeline necking adjusting device is reasonable in design, simple in structure and suitable for optimization design of variable tumble ratio systems.
