Screw-type air compressor

Abstract

The invention relates to a screw-type air compressor. The screw-type air compressor comprises a machine frame, a base, a screw-type air compressor main unit and a motor, wherein the machine frame is a plate-type supporting frame; the plate-type supporting frame comprises a fixing plate and a frame border; the screw-type air compressor main unit is fixedly arranged above the fixing plate; a main body of the screw-type air compressor main unit is arranged on the right side of the fixing plate; a belt pulley of the screw-type air compressor main unit is arranged on the left side of the fixing plate; the motor is arranged below the fixing plate; an installing hole is formed in the fixing plate; a main shaft of the motor penetrates through the installing hole and is connected with the belt pulley; elongated adjusting holes are formed in the upper parts and the lower parts of the two sides of the installing hole respectively; a fixing disc is arranged on the left side section of the motor; the fixing disc is provided with fixing holes at positions corresponding to the four elongated adjusting holes. The screw-type air compressor is high in assembling precision and convenient to adjust; during parallel downward movement, the installing accuracy of a belt drive is not affected, thus reducing the abnormal wear of a belt and ensuring the driving torque.

Description

technical field [0001] The invention relates to a screw air compressor. Background technique [0002] Screw air compressors come in pre-packaged configurations requiring a single power connection, compressed air connection and built-in cooling system to simplify installation. Screw air compressors consistently provide high-quality compressed air for all walks of life with its advantages of high efficiency, high efficiency, maintenance-free, and reliable life. [0003] Existing screw air compressor comprises frame, base, screw air compressor host and motor, and screw air compressor host and motor are respectively arranged on the upper and lower sides of the frame, and the frame is fixedly arranged on the base. There are pulleys on the host and the motor respectively, and the two pulleys are connected through a belt drive connection. Since the host and the motor of the screw air compressor are fixed, the accuracy cannot be adjusted after installation. If there is a deviation ...

[0003] Existing screw air compressor comprises frame, base, screw air compressor host and motor, and screw air compressor host and motor are respectively arranged on the upper and lower sides of the frame, and the frame is fixedly arranged on the base. There are pulleys on the main unit and the motor respectively, and the two pulleys are connected through a belt drive connection. Since the main unit and the motor of the screw air compressor are fixed, the accuracy cannot be adjusted after installation. If there is a deviation in the installation position, it will cause the belt to Abnormal wear, transmission torque cannot be guaranteed
