Chain transmission system with double-arc structure

Abstract

The invention discloses a chain transmission system with a double-arc structure and relates to the technical field of mechanical design. The chain transmission system comprises a containing cavity, an elastic part, a rotary body, a clapboard, a rotating shaft, a rotating board and a chain. The longitudinal section of the containing cavity is circular, longitudinal sections of a fixing body and the rotating body are arc-shaped, the cross section of an exhaust pipe is rectangular, a first through pipe and a second through pipe are both distributed in the fixing body, a fixing board is fixedly combined with the rotating body, and the right wall surface of the fixing body is connected with the fixing plate through the elastic part. When the pressure of an air inlet pipe of an engine is high, the rotating body drives the rotating board to rotate anticlockwise, the area of a throat portion of the exhaust pipe is relatively large, and pumping loss of the engine is less. When pressure of the air inlet pipe of the engine is relatively low, the rotating body drives the rotating board to rotate clockwise, the area of the throat portion of the exhaust pipe is relatively small, pulse energy can be fully used, and turbine-front available energy is more. The chain transmission system with the double-arc structure is reasonable in design, simple in structure and suitable for a turbine boosting system with one turbine inlet and a turbine laterally arranged.

Description

technical field [0001] The invention relates to a turbocharger system in the technical field of mechanical design, in particular to a chain drive system with a double-arc structure. Background technique [0002] With the development of society and the improvement of environmental protection requirements, the application of engine supercharging technology is becoming more and more extensive. Most of the engines with medium and high power adopt turbocharging technology to improve power and reduce fuel consumption. The two basic types of turbocharging systems are constant pressure supercharging system and pulse supercharging system. Constant pressure supercharging system, each cylinder shares an exhaust pipe with a large volume, the structure of the exhaust pipe system is relatively simple, the pressure in the exhaust pipe is basically kept constant, the pressure is only related to the load and speed of the engine, different cylinder numbers The supercharging system of the die...

AI Technical Summary

Problems solved by technology

[0003] After searching the existing technical literature, it is found that Chinese patent number ZL201020532937.0, patent name: turbocharger device with variable exhaust pipe outlet area, this patent technology provides a device with continuously variable exhaust pipe outlet area , can better take into account the high and low speed conditions of the engine; but the change of the outlet area of ​​the exhaust pipe is realized by the rotation of the rotary handle, which requires adding a special control mechanism to control the rotation of the rotary handle, so that Make the supercharging system structure more complicated
