Embodiment Construction
[0028] The present invention will be further described below with reference to the accompanying drawings.
[0029] To facilitate the description, the following mainly describes a pair of cylinders, but it is to be noted that the present invention can not only be applied to a pair of cylinders, and the method and structure of the arrangement in the direction of the crankshaft are also in the scheme of the present invention.
[0030] See figure 1 However, the piston force acting on the piston can be broken down into two directions, and the link force in the direction of the link is perpendicular to the lateral force perpendicular to the center of the cylinder, which causes the piston to extrud the cylinder wall surface, Force to the casing. The connecting force is transmitted to the main bearing of the crankshaft, which can be broken down into the force in the direction of the cylinder head and the force perpendicular to the centerline direction of the cylinder. It can be known that...

A reciprocating compressor with automatic lateral force balance, including several cylinders arranged in pairs in a compressor casing, each pair of two cylinders is respectively equipped with pistons, and the two pistons pass through two connecting cylinders respectively. The rod connects the two crankshafts, and the two crankshafts rotate in opposite directions and at equal speeds, so that the overturning moments of the two cylinders have the same value but opposite directions and cancel each other out, realizing the automatic balance of the lateral force of the reciprocating compressor. In each pair of two cylinders, two motors are used to drive two crankshafts respectively, and by controlling the rotation speed and direction of the two motors, the rotation directions of the two crankshafts are opposite and the speeds are equal. Or adopt a motor to drive two crankshafts, a pair of synchronous gears are installed on the two crankshafts, one of the crankshafts is connected with the motor to provide power, and the rotation directions of the two crankshafts are opposite and the speeds are equal through the synchronous gears. The invention can greatly reduce the vibration noise of the machine and has good application prospects.
Description
Technical field [0001] The present invention belongs to the field of compressor structural design, and more particularly to a reciprocating compressor for automatic balance of lateral force. Background technique [0002] The piston compressor is one of the volumetric compressor, and the cylinder of the piston compressor can be arranged separately or within the same chamber. According to the relative position of the cylinder center line and the ground, it can be divided into vertical, horizontal and angular, and the piston compressor forms a closed volume through the cylinder, the gas valve, and the piston, and the piston is reciprocated in the cylinder to change the working volume. It has the advantages of wide pressure range, and wide exhaust range are widely used in various industrial applications. [0003] For each column cylinder, during the process of reciprocating the piston, the piston force acting on the piston can be broken down into a linkage force along the link and a ...
