Combined diesel motor rotor workpiece and assembling method thereof

Abstract

The invention belongs to the technical field of motor production and processing, and particularly relates to a combined diesel motor rotor workpiece and an assembling method thereof. The combined rotor core is composed of a plurality of groups of splicing blocks which are arranged side by side, each group of splicing blocks is formed by butting a splicing block I and a splicing block II which are symmetrical in structure, each of the splicing blocks I and the splicing block II comprises a sheet body, and a central through hole, a lead-in hole, a movable groove, a permanent magnet mounting hole and a welding groove are formed in each sheet body; during assembly, the combined rotor iron core is formed by welding firstly, then the combined rotor iron core is sleeved in the rotating shaft, and the shifting column on the rotating shaft enters the lead-in hole and then rotates into the movable groove, so that the assembly can be completed. The rotor workpiece provided by the invention is reasonable in structural design, can be assembled through staggered clamping, does not need to be provided with a thread locking and anchoring locking structure, and is beneficial to assembly and later disassembly and replacement.

Description

technical field [0001] The invention belongs to the technical field of motor production and processing, and particularly relates to a combined diesel motor rotor workpiece and an assembling method thereof. Background technique [0002] The rotor iron core is a punched lamination structure. At present, in order to improve the mechanical strength of the rotor iron core, the rotor iron core will be fastened together by means of rivets after lamination. For longer diesel generators, the length of the rotor iron core used will also be longer, and the current lamination process is difficult to laminate the rotor iron core into an integral type, so the rotor iron core generally adopts a segmented design . The rotor core of the traditional segmented motor is fastened by rivets for each segment, so there will be a gap between the two adjacent rotor cores, and the length of this gap is the length of the ineffective electromagnetic action, which eventually leads to an increase in the ...

AI Technical Summary

Problems solved by technology

[0004] However, this segmented motor rotor core still has disadvantages when it is used. First, the direction of rotation of the thread groove is the same as the working direction of the rotating shaft, which will easily lead to loosening of the locking ring for a long time; second, it is not conducive to automatic assembly.
