Example Embodiment

[0011] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0012] Such as figure 1 As shown, the oil-cooled screw air compressor coaxial with the motor includes an air compressor main body 1 and a circulating oil system. A body bracket 2 is provided at the rear of the air compressor main body. The body bracket 2 is centered A motor housing 3 is installed, and a cooling interlayer 4 is provided on the motor housing 3.

[0013] The inner wall of the motor housing 2 is provided with a motor stator 5, the motor housing 1 is provided with a motor rotor 6 which is fastened to the drive shaft 7 of the air compressor main body Thus forming a whole. In this embodiment, the drive shaft 7 of the air compressor main body extends into the motor housing 3, the motor rotor 6 is sleeved on the drive shaft 7 of the air compressor main body, and the air compressor The drive shaft 7 of the machine main body and the motor rotor ...

Abstract

The invention relates to an oil-cooled screw air compressor coaxial with a motor, which comprises an air compressor host and a circulating oil system. The tail part of the air compressor host is provided with a machine body bracket; a motor shell is arranged on the machine body bracket in a centering mode; the motor shell is provided with a cooling interlayer; the inner wall of the motor shell is provided with a motor stator; a motor rotor is arranged in the motor shell; the motor rotor is fastened with a driving shaft of the air compressor host so as to form one whole body; the cooling interlayer on the motor shell is communicated with the circulating oil system by an oil pipe. According to the invention, the rotor of the motor is arranged on the driving shaft of the air compressor host, so that the transmission efficiency of the motor achieves 100 percent; the oil-cooled screw air compressor fulfills the aim of integrating the motor with the air compressor host into one whole body, so that the motor is not provided with a bearing, fault points of the motor are eliminated and no maintenance of the motor is implemented.

Description

technical field [0001] The invention relates to a screw air compressor. Background technique [0002] Energy saving and emission reduction is a long-term goal in the process of my country's national economic development, and it is also a very important part to reduce the noise of the unit and improve the reliability of the product. At present, the air compressor industry basically uses an air-cooled motor to drive the main engine of the air compressor, and the motor and the main engine are integrated; for the direct connection, it is connected through the center bracket and the coupling. It is guaranteed by the manufacturing accuracy of the center bracket and the elastic compensation of the coupling, which not only complicates the assembly and high cost, but also reduces the transmission efficiency and affects the reliability of the product. The air-cooled motor uses the airflow generated by its own fan to dissipate the heat generated during the excitation process, and the ...
