The advantages and disadvantages of five methods for repairing the high-speed shaft of planetary reducer are as follows:
Advantages: low price.
Disadvantages: small contact area, short service life and large equipment bounce.
2. Brush plating and spraying
Advantages: small thermal stress, relatively small damage to materials.
Disadvantages: limited wear size, unable to repair on site, easy delamination and high cost.
3. Copper plug
Advantages: low price, fast maintenance.
Disadvantages: small contact area, short service life and large hidden danger.
4. Machining after repair welding
Advantages: low maintenance cost.
Disadvantages: unable to repair repeatedly; Major accidents caused by easily broken shaft; Large hidden danger and high comprehensive cost.
5. Sorey Carbon Nanopolymer Material Technology
Advantages: no thermal stress, unlimited wear, short maintenance cycle, low maintenance cost, simple operation, online repair or offline repair. Its scope of application includes: wear repair of various bearing positions, bearing chambers (seats), keyways, threads, etc; Casting defects, cracks, transformer oil leakage; Protection of pumps, turbines, tanks, condensers, etc.
