Anti-Loose Treatment Of Threaded Fasteners During Assembly Of Electric Locomotive

Manufacturing technology Anti-loose treatment of threaded fasteners during assembly of electric locomotives Measures for loosening of fasteners. With the continuous improvement of railway locomotive speed requirements for electric locomotives, the quality of threaded connections is becoming more and more important for the safe operation of trains.

With the continuous improvement of railway locomotive speed requirements for electric locomotives, the quality of threaded connections is increasingly important for the safe operation of trains. In the assembly work of electric locomotives, the threaded connection is an important process, and the anti-loose treatment of the threaded fasteners is also very necessary.

Threaded connection features and requires threaded connection to obtain a large connection force, easy to assemble and disassemble, low cost, and interchangeable, widely used in electric locomotives. With the development of electric locomotives in the direction of high speed, high power, precision, small size and light weight, higher requirements are placed on the performance and fastening work of threaded fasteners: the performance of threaded fasteners is predictable and the dispersion is small. The relationship between tightening torque and bolt elongation is accurate and stable; the nut will not loosen after tightening, will not be killed when disassembled, and can be reused.
