Problems solved by technology
Although this method can solve the above-mentioned problems, due to the small size of the circular slider itself, an eccentric circular hole must be provided, so that the size of the locking structure is limited. prone to failure
Therefore, there are obvious defects in this split round slider

Embodiment Construction
[0026] The first embodiment of the present invention provides a crankshaft of a small two-stroke single-cylinder internal combustion engine. The crankshaft includes a single throw provided with a crank pin and a crank combined with the single throw, and the two are assembled to form a complete crankshaft.
[0027] Figure 1 shows the combined crankshaft. in, Picture 1-1 is the front view of the single throw of the crankshaft; Figure 1-2 show Picture 1-1 The right view of the single turn; Figure 1-3 is the front view of the crank of the crankshaft; Figure 1-4 is the left side view of the crank of the crankshaft; Figure 1-5 It is the front view of the assembled crankshaft.
[0028] Please see Picture 1-1 . The single throw of the crankshaft includes three parts, the single throw main journal 5, the first crank arm 22, and the crank pin 21 whose axes are parallel to each other and which are connected successively. The three parts are all cylindrical and have different ...

The invention discloses a crankshaft used for a crank circular slider internal-combustion engine or a compressor, comprising at least a group of crutches and cranks which cooperate with each other and are independent from each other; the crutch is provided with at least an extended crank pin; each crank pin is corresponding to an independent crank which is provided with through holes for the crank pin corresponding to the crank to insert, therefore, the through holes are called crank sockets; the crank adopts the way that the crank pin inserts the crank socket corresponding to the crank to realize the connection between the crank pin and the crank socket to form a complete crankshaft. The front part of the crank pin of the crutch and the crankshaft is a cone end. The crank sockets are cone holes with the taper matched with the cone end of the front part of the crank pin. A pair or two pairs of locating semi-holes are respectively arranged on the cone end and the cone holes. The crankshaft provided by the invention is composed of detached crutches and cranks, and can be conveniently disassembled. The position relation therebetween after the disassembly does not change.
Description
technical field [0001] The invention relates to a crankshaft of an internal combustion engine or a compressor, in particular to a crankshaft of a crank-round slider internal combustion engine or a compressor. The invention also relates to an internal combustion engine and an air compressor using the crankshaft. Background technique [0002] Both reciprocating internal combustion engines and compressors need to realize the conversion between the reciprocating motion of the piston and the rotational motion of the crankshaft. Among them, the reciprocating internal combustion engine converts the reciprocating motion of the piston into the rotational motion of the crankshaft, while the reciprocating compressor converts the reciprocating motion of the crankshaft. The rotary motion of the piston is converted into the reciprocating motion of the piston. Under the current common technology, the above-mentioned conversion process all needs to use the crank-link mechanism. Due to the...
