Large Size Armature Heat Sleeve Double Commutator

Recently, we received the armature repair task of Texas DC Motor JH-166, which is a challenge and an attempt for us. Because it must be processed in strict accordance with the production requirements and standard procedures of marine motors. So this task is a challenge for us! It's very difficult. In fact, every new thing is to say no to the impossible! We did it this time.

It's not easy to learn from paper, but it's necessary to do it by oneself. DC product craftsmen and professional craftsmen cooperation, from the commutator processing to the hot sleeve pressure mounting to dynamic balancing, painting the whole process are rigorous and careful combing of the new row process and processing methods. Especially the hot set of the commutator is the most important, due to the DC armature has never processed such a large product, and finally decided to heat set the commutator in the machine on the high-pressure 315-ton four-column hydraulic press. Its process method, whether from the material, tooling equipment, process preparation, processing, etc. are careful. 

Please look at this armature, this armature core outer diameter is 1.2 meters, the thickest part of the shaft 0.51 meters, a total height of 2.57, a total weight of nearly 4.5 tons, just this head can be imagined its difficulty. The motor armature for the hollow shaft, lifting with false mandrel and both ends of the plug, the commutator is a vertical hot set process, due to the rotor shaft is particularly long to be completed at a height of 3 meters, armature core turning process can not land. Can think of its process difficulties, not only to ensure the size of the press-fit and to ensure the absolute safety of people and products.

Each processing step, process personnel are personally on-site to guide the operation, commutator pressure mounting, the operation of more than a dozen workers in close cooperation with the operation, very tacit understanding, stable commutator hot set success!

Simo motors craftsmanship has the heritage, the staff is worthy of the great national craftsmen!
