[0002] A Chinese patent with announcement number CN208348319U discloses a connection structure between a motor and a machine head in a screw compressor. The motor includes a casing and a rotating shaft arranged in the casing. A concave cavity is provided on one side of the casing, and one end of the rotating shaft is located in the concave cavity. The connection structure includes a connecting hole provided on the end of the rotating shaft and a cylindrical connecting part on the machine head. The side wall of the concave cavity is a cylindrical surface matching the connecting part, and the outer peripheral surface of the connecting part is in contact with the side wall of the concave cavity. The connecting hole is strip-shaped and the length of the connecting hole extends along the axial direction of the rotating shaft. The main shaft of the machine head extends into the concave cavity and is inserted into the connecting hole, and the main shaft and the rotating shaft are connected by a spline.

[0003] The above-mentioned screw air compressor extends the head main shaft into the casing and connects it to the motor shaft through a spline, which effectively shortens the length of the connection structure and ensures that the shaft and the main shaft always maintain a high degree of coaxiality, thereby effectively improving the accuracy and stability of the transmission process.

[0004] Since the motor and the head of the screw air compressor are very heavy, it is inconvenient to move the motor toward the head of the screw air compressor during installation, which makes it more laborious to install and splice the motor and the head of the screw air compressor.

[0005] Therefore, a battery-driven screw air compressor motor high-efficiency drive system is proposed. Utility Model Content

The rotating shaft of the motor body 1 is connected to the main shaft on the head 2 of the screw air compressor through the spline, and the convex spline is inserted into the concave spline. The above structure is the same as the structure of the connection structure between the motor and the head in the screw compressor disclosed in the Chinese patent with announcement number CN208348319U. By adopting the above structure, the length of the connection structure between the motor body 1 and the head 2 of the screw air compressor is effectively shortened, and it is ensured that the rotating shaft and the main shaft always maintain a high coaxiality, thereby effectively improving the accuracy and stability of the transmission process, making the transmission of the motor body 1 more efficient.

[0026] The head 2 of the screw air compressor is fixedly mounted on the mounting base 3, and the mounting base 3 is fixedly connected to the slide rail 4.

The lower end of the locking bolt passes through the locking hole 1011 and is threadedly fixed in the threaded hole 401.

[0027] When installing the motor body 1 and the head 2 of the screw air compressor, rotate the screw 5 to move the motor body 1 toward the main shaft of the head 2 of the screw air compressor, so that the concave spline on the rotating shaft of the motor body 1 is sleeved on the convex spline on the main shaft of the head 2 of the screw air compressor. At this time, the motor body 1 is fixed to the slide rail 4 with the locking bolt, and the entire installation process is convenient and quick. By starting the motor body 1, the rotating shaft on the motor body 1 drives the main shaft of the head 2 of the screw air compressor to rotate.
