Abstract

The utility model relates to a welding machine base for a pulse flow traction motor, which is formed by welding and assembling a magnet, a commutator chamber, an axle hung upper support and some other upper parts, wherein the commutator chamber is also formed by welding and assembling a plurality of parts. The structure of the machine base after being assembled and welded is identical with that of the existing casting machine base, the utility model just changes the existing casting integration machine base into a machine base formed by welding and assembling a plurality of parts, and each split part has corresponding structure on the existing casting machine base; therefore, when the machine base of the utility model is assembled and welded, the relation between relative positions of parts is known and the parts can be assembled and welded according to the existing casting machine base. The welding machine base for a pulse flow traction motor has the advantages of stable dimension of the machine base, homogeneous wall thickness of the magnet, good performance of conducting magnet of motors and centralized rate characteristics, can be loaded without rate matching, enhances appearance quality of motors, prevents the machine base from cracking in use, saves much maintenance cost and enhances the competitive power of products.

Description

The welding frame of pulsating current traction motor

Technical field

The utility model relates to the support of pulsating current traction motor, is specially a kind of welding frame of pulsating current traction motor.

Background technology

The pulsating current traction motor (ZD12) that China railways electric locomotive SS4G adopts at present, its support is cast frame, and magnetic property is poor, and the motor speed characteristic is disperseed, and needing classification to join speed can use in entrucking; Simultaneously the support cracking phenomena often taking place in use, cause locomotive to stop and return weldering, causes a hidden trouble to railway security; In addition, the cast frame presentation quality is poor.

Summary of the invention

The utility model solves the problem that the pulsating current traction motor cast frame exists, and a kind of welding frame of pulsating current traction motor is provided.

The utility model is to adopt following technical scheme to realize: the welding frame of pulsating current traction motor, be welded by magnet, commutator chamber, seize upper support and all the other some upper-part assemblings, and wherein the commutator chamber also is to be welded by some component-assembled.Support described in the utility model, structure after its assembling welding is identical with existing cast frame, just with existing casting integrated formula support, change into by some split component-assembled and being welded, each divides body component (as the component parts of support, seize upper support and commutator chamber etc.) that corresponding with it structure is all arranged on existing cast frame, therefore, support described in the utility model is when the assembling welding, mutual alignment relation between each parts is known, promptly assembles and weld according to existing cast frame to get final product.

The welding frame of this pulsating current traction motor, the support dimensionally stable, the magnet wall thickness is even, and the motor magnetic property is good, and speed characteristic is concentrated, and need not join speed and get final product entrucking; Improved the presentation quality of motor; The prevention support in use ftractures, and saves a large amount of maintenance costs; Strengthened competitiveness of product.
