Processing Technology of Thrust Disk of Large Shielded Motor

Abstract

The invention relates to a processing technology of a thrust plate of a large-scale shielded motor: a. Rough turning of the welded parts of the thrust plate on a lathe; b. Finish turning of the rough-processed thrust plate; c. Clamping of the thrust plate to a grinding machine for work On the table, grind the inner hole of the thrust disc; d. heat and install the thrust disc on the tool plug; e. place the thrust disc where the tool plug is installed on the thrust disc grinding tire for grinding; f. use three coordinates to work on the thrust disc Check the surface and non-working surface; g. Remove the thrust plate from the tool plug, clean it and store it for subsequent use. The invention improves the motor processing and assembly quality, ensures the stability of the thrust disc under the running state of the motor, and supports the thrust disc by using the ground contour support nails to ensure the processing accuracy of the thrust disc and improves the qualified rate of the product , and standardized the inspection method of the thrust disc, which improved the operability.

Description

Technical field: [0001] The invention relates to the processing technology of the thrust disk of a large-scale shielded motor. Background technique: [0002] Due to low efficiency, shielded motors were only used in small equipment in the past, but as the country vigorously promotes nuclear power projects and the development of nuclear power main pump motors, shielded motors have higher safety and longer service life. High-power shielded motors have been developed and produced successively. As the power of shielded motors increases, the thrust discs of shielded motors also become larger. The processing requirements are also getting higher and higher. [0003] In the past, the structure size of the thrust disc of the small shielded motor was very small, and it was easy to meet its size requirements during processing. However, the thrust plate of a large shielded motor is also a kind of thin-walled part due to its structural change, and it is easy to deform during the process...
