This creation provides a designer of a submersible pump type five motor drive unit.

In order to enable your review committee to have a better understanding and understanding of the purpose, characteristics and efficacy of this creation, the implementation method and the schema are as follows: See the first to fourth figures, this creation provides a submerged water. The pumped five-type motor driving device comprises: a five-type motor 10, the five-type motor 10 has a standard outer diameter of 120 mm, and the five-type motor 10 includes an inner pivoting shaft 11 protruding outwardly and protruding outward. The end of the shaft 11 is provided as a spline tooth end 111; a coupling sleeve 20 is recessed with a spline groove 21, the spline groove 21 is coupled with the spline tooth end 111; and an impeller group 30 is provided with a transmission shaft a hole 31; a transmission shaft 40 is sleeved to the drive shaft hole 31 of the impeller group 30, the foregoing transmission A threaded hole 41 is disposed on the end surface of the shaft 40. The connecting sleeve 20 is provided with a groove 22 having the same outer shape as the transmission shaft 40. The connecting sleeve 20 is provided with a through hole 23 aligned with the threaded hole 41, and a screw 50 is passed through the foregoing. The through hole 23 is screwed to the threaded hole 41 to fix the transmission shaft 40 and the coupling sleeve 20; wherein the spline tooth end 111 is formed as a 13-tooth spline tooth 1111, the 13 teeth The spline tooth shape 1111 has a thickness of 17.8 mm, a thick tooth thickness, good strength, shear resistance, and torsion resistance, and a combination of better joint strength and lower transmission wear.
