Oilless air compressor of integrated air circuit

Abstract

An oilless air compressor of an integrated air circuit comprises a motor shell, a motor shaft, a crankcase, a side cylinder cover, a cooling fan, a cylinder, an air director and a fan connection assembly which are matched mutually, wherein the motor shell is formed once through an extrusion drawing process, and meanwhile, a pipeline is formed integrally on the motor shell. The crankcase and the air compressor motor shell are connected integrally fixedly. The fan connection assembly comprises a T-shaped connection shaft and a connection support which are matched mutually. The T-shaped connection shaft is connected with the fan. The connection support is connected with an eccentric wheel. The motor shaft rotates to drive the eccentric wheel to rotate, then through the connection support on the eccentric wheel, finally the connection support and the T-shaped connection shaft are matched, thus power is output to drive the fan to operate synchronously, assembly error is reduced, cost is lowered, and complete machine vibration and noise are optimized.

Description

Technical field: [0001] The invention relates to an oil-free air compressor, in particular to an oil-free air compressor in which a motor end cover and a crankcase of the air compressor are integrally formed, and a pipeline is integrally formed on the motor casing to form an integrated air circuit. Background technique: [0002] The existing oil-free air compressor structure has the following disadvantages: [0003] 1. The motor end cover and the crankcase of the existing oil-free air compressor are connected separately, resulting in high assembly accuracy requirements, large errors, and low strength. [0004] 2. The air inlet and outlet pipes of the existing oil-free air compressor are all exposed, resulting in poor aesthetics, high cost, and poor heat dissipation of the motor. [0005] 3. The heat dissipation structure of the existing oil-free air compressor is an external heat dissipation structure, which has poor heat dissipation, high configuration cost, poor stability...
