Problems solved by technology

The U-shape of the existing double crankshaft and the V-shape of the single crankshaft mainly balance the reciprocating inertial force and moment, rotational centrifugal force and moment by installing a balance weight on the transmission shaft. The shape and so on increase the difficulty of the design of the heat engine transmission system

Abstract

The invention discloses an eight-cylinder heat engine transmission system, comprising: an eight-cylinder heat engine crankshaft, an upper balance shaft and a lower balance shaft; the axes of the eight-cylinder heat engine crankshaft, the upper balance shaft and the lower balance shaft are parallel to each other; The machine crankshaft includes a main journal, four pairs of crank throws, a free end and an output end; the phase difference between the two crank throw units of each pair of crank throws is 180°. The first crank unit of four pairs of bell cranks jointly forms the first four-cylinder double-acting heat engine, and the second crank unit of four pairs of bell cranks jointly forms the second four-cylinder double-acting heat engine; the first four-cylinder double-action The heat engine transmission unit and the second four-cylinder double-acting heat engine transmission unit are relatively arranged on two sides of the crankshaft axis of the eight-cylinder heat engine, and the working phase difference is zero. The invention improves the service life of parts, reduces the external dimension of the eight-cylinder heat engine, reduces the vibration and noise of the heat engine, facilitates the lubrication of bearings, and improves the operation reliability and long-term operation stability of the transmission system of the heat engine.

Description

technical field [0001] The invention relates to the technical field of heat engines, in particular to an eight-cylinder heat engine transmission system. Background technique [0002] The heat engine is a closed-cycle piston type and new type of external combustion engine heated by external energy. It has high cycle thermal efficiency, good torque-speed characteristics, stable operation, low vibration and noise, clean emission, and can be used for various fuels or energy sources. etc., so it has a wide range of applications and application prospects. [0003] Although the four-cylinder heat engine is the most widely used model, in order to meet the high power demand of the heat engine, the eight-cylinder heat engine is produced accordingly. The common transmission form of the four-cylinder heat engine and the eight-cylinder heat engine is the U-shaped double crankshaft. 1. There are two types of V-type single crankshaft. The double-crank U-shaped transmission structure is ma...
