Pressure Ring of Locomotive Motor In Railway

Introduction of Pressure Ring of Locomotive Motor

 In the precision of rail transit equipment architecture, the motor system is like a beating heart, while a seemingly ordinary motor compression ring maintains the “heart,” the key to the steady beat device. As the core pressure-bearing component of the modern locomotive power system, this ring-shaped component with a diameter of no more than tens of centimeters shoulders the important mission of ensuring the efficient operation of the traction motor.

The Material of Pressure Ring of Locomotive Motor

Mechanical aesthetics of the essence of the design of industrial aesthetics; the ring structure is not simple geometric shapes. Engineers found through finite element simulation that a continuously closed circular ring can uniformly distribute the load in the 360° direction, reducing local stress concentration by 37% compared with polygonal structures. This bionic design is inspired by the ring-shaped skeletal structure of crustaceans in nature, achieving a golden balance between mass and strength while ensuring structural rigidity.

Materials science, the modern press circle uses S355J2G3 more special alloy steel, after vacuum degassing treatment of material with amazing mechanical properties. Its yield strength reaches 355MPa, the elongation exceeds 22%, and it can still maintain excellent impact toughness in a low-temperature environment of -40℃. Even more ingeniously, material engineers injected 0.02% niobium into the steel matrix through microalloying technology, refining the grain size to ASTM grade 10 and effectively suppressing the fatigue crack propagation caused by long-term vibration.

The Manufacturing Technology of Pressure Ring of Locomotive Motor

Manufacturing technology of metal processing technology. In the precision forging workshop, a 10,000-ton hydraulic press shapes the fiery red steel billets, and the mold temperature needs to be precisely controlled within±5℃. In the subsequent CNC machining process, the five-axis linkage machine tool carves the toothed positioning surface with a positioning accuracy of 0.01mm, and the surface roughness Ra value is strictly controlled below 1.6μm. The final ion nitriding treatment process makes the surface hardness reach 800HV, forming a 50μm thick strengthening layer, which is like putting a diamond armor on the pressure ring.

The Function of Pressure Ring of Locomotive Motor

With the wisdom of the dynamic guard at 350 km/h, under the condition of pressure ring to carry 83 revolutions per second centrifugal load and temperature rise test of 200℃. The newly developed intelligent pressure ring is implanted with a micro-optical fiber sensor, which can monitor the strain distribution status in real time. When the local stress exceeds the preset threshold, the control system will automatically adjust the motor output torque. This active protection mechanism extends the component life by 2.8 times. After applying this technology to a certain type of plateau locomotive, it set a record of continuous operation for 1.2 million kilometers without failure in a harsh environment at an altitude of 5,000 meters with a temperature difference of 40℃ between day and night.

The Innovation of Pressure Ring of Locomotive Motor

The green manufacturing of innovative practices in the context of carbon neutral, compression ring green revolution is going on manufacturing. The low-temperature near-net-shape forming process developed by a certain enterprise has increased the material utilization rate from the traditional 58% to 92%, reducing steel scrap by 4,200 tons annually. Even more creatively, the scrapped pressure rings, after being repaired by laser cladding, can be re-putted into the secondary use market through a digital re-certification system. This recycling technology has been certified by the IRIS international railway standard. The fact is, these seemingly simple metal rings condensed mechanical engineering, material science, and many domains, such as smart sensing industrial crystallization of wisdom. From the Harmony bullet train on the coast of the Bohai Sea to the Fuxing bullet train on the Qinghai-Tibet Plateau, countless precision pressure rings are quietly safeguarding the steel veins of China’s rail transit. They tell the story of China’s intelligent manufacturing with the tenacity of metal and carry the power of The Times’ progress with the circular inclusiveness – perhaps this is the most poetic expression of industrial civilization.
