Conical centrifugal tensile mechanism

A conical centrifugal tensile mechanism in the technical field of mechanical design comprises an adjusting body, a rotating shaft, a rotating body, a tensile body, a centrifugal body, a ball, a pull rod and springs. The rotating shaft and the rotating body are fixedly connected together. The tensile body and the centrifugal body are both arranged in the rotating body. The ball is embedded in the tensile body. One side wall of the centrifugal body makes contact with the tensile body through the ball. The other side wall of the centrifugal body is connected with the inner wall face of the rotating body through the first spring. The top of the tensile body is connected with the inner wall face of the rotating body through the second spring. In the conical centrifugal tensile mechanism, when the rotating speed of an engine is high, an adjusting plate moves upwards, the front exhaust total capacity of a turbine is large, and pump gas loss is small; when the rotating speed of the engine is low, the adjusting plate moves downwards, the front exhaust total capacity of the turbine is small, and the discharge pulse energy can be sufficiently used. The conical centrifugal tensile mechanism is reasonable in design, simple in structure and suitable for optimized design of turbine boosting system exhaust pipe capacity.
