Abstract
The invention relates to a two-end-face linear contact system and belongs to the technical field of machine design. The two-end-face linear contact system comprises an adjustment body, a rotating shaft, a rotating body, a stretching body, centrifugal bodies, balls, a pull rod and springs. The rotating shaft and the rotating body are fixedly combined. Both the stretching body and the centrifugal bodies are arranged in the rotating body. The balls are inlaid in the stretching body. One side wall of each centrifugal body makes contact with the stretching body through the corresponding ball. The other side wall of each centrifugal body is connected with the inner wall surface of the rotating body through the corresponding first spring. The top of the stretching body is connected with the inner wall surface connected with the inner wall surface of the rotating body through the second spring. According to the two-end-face linear contact system, when the rotating speed of an engine is high, an adjustment plate moves upwards, the air exhaust amount of a turbine is large, and the pumping loss is small; when the rotating speed of the engine is low, the adjustment plate moves downwards, the air exhaust amount of the turbine is small, and the air exhaust pulse energy can be fully utilized. The two-end-face linear contact system is reasonable in design, simple in structure and suitable for optimal design of turbine exhausting systems.
