المواد والعمليات
The following eccentric shaft material and process notes support specification checks and replacement assessment.
34CrNiMo6 Alloy Steel
The eccentric shaft is a precision forging subject to cyclic loading. 34CrNiMo6 is a candidate quenched and tempered alloy steel; confirm the grade, section size, strength, toughness and hardness against the machine drawing.
Heat Treatment
Specify quenching and tempering, local hardening and non-destructive testing for the material, section size and drawing. Control forging defects, fatigue-critical areas and heat-treatment distortion.
Comparison of Similar Material Grades
Compare 34CrNiMo6 with nominally similar national grades by composition, hardenability, section properties and inspection standards. Do not assume unconditional equivalence.
Bearing Seat Accuracy
Inspect bearing-seat cylindricity, surface finish, coaxiality and eccentricity against the machine drawing. Eccentricity directly affects the swing jaw stroke.
Wear and Replacement Criteria
The following eccentric shaft wear patterns and replacement guidance support maintenance planning.
Main failure modes
Common damage includes bearing-seat and shoulder wear, fatigue cracks and bending. Determine repair or replacement from dimensional inspection, non-destructive testing and operating condition.
Replacement Criteria
Inspect for bearing-seat wear causing a loose fit, fatigue cracks or spalling on journals, and shaft bending beyond the drawing tolerance.
Recommended Actions
Monitor bearing temperature and vibration, maintain the lubrication system and regularly check bearing clearance and fits.
Information Needed for an Inquiry
المعدات model (such as C200), part number, material requirement (34CrNiMo6), forging class, non-destructive testing requirements and quantity. Provide the original drawing to confirm dimensions.
