The air compressor crankshaft is a very important part of the compressor. There are many demands for compressor crankshafts in life, so it is very important to choose and use compressor crankshafts reasonably. Many manufacturers and consumers have a great demand for compressor crankshafts. What is the out-of-tolerance of compressor crankshaft? How to deal with it?

Out-of-tolerance difference of compressor crankshaft is a concrete manifestation of wear. Generally, when the wear amount is less than or equal to ≤0.05mm, the difference of roundness and cylindricity is eliminated manually; When the wear amount is more than >0.05mm, the difference of roundness and cylindricity is removed by machining, and the machining is carried out on crankshaft grinder and special machine tool, which has high machining precision.

1. measure the direction and position of multi-point roundness and cylindricity difference, and make marks on both sides.

2. File manually with a fine flat file, and measure while filing, knowing that the difference between roundness and cylindricity of journal is less than allowable value.

3. Use a cloth belt with the width equal to the length of the journal, put 0# emery cloth on it, and stick it on the side of the journal to be ground.

4. Two people pull the cloth belt at an angle of 60, cooperate with pulling the cloth belt to make reciprocating motion, grind one side, then grind the other side, and measure the journal. The difference between roundness and cylindricity is less than the allowable value.

5. Wrap double 0# emery cloth around the entire journal and twine it around the emery cloth for several times

6. Two people pull the hemp rope with their hands on both sides, and cooperate to pull the hemp rope to make reciprocating motion and grind the shaft neck

7. Wrap the whole journal with metallographic sandpaper, and wrap the sandpaper several times with hemp rope

8. Two people pull the hemp rope with their hands on both sides, and cooperate with pulling the hemp rope to make reciprocating motion to polish the shaft neck.

Compressor crankshaft is very important for compressor, so it is very important to choose compressor crankshaft reasonably. There is a great demand for compressor crankshafts in life. Reasonable selection has high benefit. The above simply describes the treatment method of compressor crankshaft out-of-tolerance.
