This paper conducts a structural safety optimization study on the gear strength of the automatic cranking device for natural gas reciprocating compressor units, aiming to enhance their overall reliability. By replacing the gear material with 20Cr and optimizing the radius of the fillet at the tooth root, the contact stress on the tooth surface was reduced by 46.3%, and the bending stress at the tooth root decreased by 31%. Both of these indicators fell below the allowable stress threshold after optimization. The research results show that the reliability of the optimized cranking device has been significantly improved, providing an effective solution for the safe and efficient operation of natural gas compressor units.
