Problems solved by technology
[0004] The core component of the disc solar Stirling generator system is the Stirling engine. Its internal power conversion transmission mechanism roughly has a diamond-shaped mechanism and a crankshaft connecting rod mechanism. These two transmission mechanisms have long transmission chains, many parts, and large volume. The cost is high, and the key problem is that the power output axis is perpendicular to the reciprocating linear motion axis of the piston, which is not completely suitable for the dish solar Stirling engine system

The invention relates to a four-cylinder double-acting Stirling engine, specifically a swash plate transmission device of the Stirling engine, which is mainly matched with a butterfly solar Stirling generator system. The Stirling engine swash plate transmission device is to push the linear reciprocating motion of the four-cylinder double-acting Stirling engine piston through the high-speed joint bearing to push the swash plate on the coaxial to swing, and convert the power into a coaxial circular motion. Its structure includes four-cylinder piston group, guide positioning plate, four high-speed joint bearings, output shaft of turntable and swash plate casing, and swash plate casing. The swash plate transmission device is composed of a swash plate shell output shaft, bearings, and a turntable, and is connected to the cylinder piston connecting rod through a high-speed joint bearing. The center line of the swash plate shell output shaft coincides with the body center line, and the four-cylinder piston group is relatively The lines are center-symmetrically distributed, and the phase difference between two adjacent pistons in the four-cylinder piston group is 90 degrees. The linear reciprocating motion of the pistons converts the power into circular motion on the same axis through the swing of the swash plate.
Description
technical field [0001] The invention relates to the field of mechanical technology, in particular to a four-cylinder double-acting Stirling engine swash plate transmission device used in a disc solar Stirling generator system. Background technique [0002] The 711 Institute of my country Shipbuilding Industry Corporation introduced the Stirling engine technology into China in the 1980s and applied it on submarines as the core power equipment; in recent years, the 711 Institute has commercialized the Stirling engine technology and has developed 3 natural gas Driven by a 50KW class four-cylinder double-acting Stirling machine.
