Crankshaft mechanism of multistage gas compressor

Abstract

The invention discloses a crankshaft mechanism of a multistage gas compressor; and the crankshaft mechanism is arranged in a crankcase of the multistage gas compressor. The crankshaft mechanism comprises a crankshaft and a transmission mechanism; the transmission mechanism includes a connecting rod mechanism; and one end of the connecting rod mechanism is in transmission connection with the crankshaft, and the other end of the connecting rod mechanism is in transmission connection with a piston in a compression cylinder. The crankshaft mechanism is characterized in that a crank throw is arranged on one side of the crankshaft; the connecting rod mechanism is in transmission connection with the crank throw; one side of the crankshaft, which is opposite to the crank throw, is provided with a balance block; the balance block is eccentrically mounted on the crankshaft, and the eccentric direction thereof is opposite to the eccentric direction of the crank throw; and the balance block is used for balancing the eccentric force when the crankshaft rotates. The crankshaft mechanism of the multistage gas compressor solves the problems of serious wear and short service life.

Description

technical field [0001] The invention relates to a crankshaft mechanism, in particular to a crankshaft mechanism of a multistage gas compressor. Background technique [0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is often used to provide gas power for pneumatic tools, and is also often used to pressurize oxygen, natural gas and other gases. The current gas compressor mainly compresses the gas through the cylinder. In order to ensure a higher gas pressure, the gas compressor often adopts multi-stage compression to achieve the purpose of boosting. Multi-stage compression requires multiple piston cylinders to compress the gas. The pistons of the piston cylinders are driven by the crankshaft installed in the crankcase of the gas compressor. When the crankshaft moves, it will be subjected to a large eccentric force. As the pressure of the gas becomes higher and higher, the air pressure reaction force received by the piston...
