Take a look at these spur gears we regularly refurbish for one of our customers! These include a 38-tooth 1-1/2DP 20° pressure angle spur gear and a 24-tooth 1-1/2DP 20° PA spur gear, both crafted from 8620 steel with hardened teeth for durability and performance.
Refurbishing spur gears involves several steps to restore them to optimal condition, typically focusing on wear, surface damage, or alignment issues. Here’s an brief scope of our process:
Inspection and Assessment: Each gear is thoroughly inspected for wear, cracks, surface pitting, and other damage. Measurements are taken to determine if critical tolerances are still met, ensuring the gear can be salvaged.
Cleaning and Preparation: Gears are cleaned to remove any debris, oil, or old coatings.
Repairing Worn or Damaged Teeth: Depending on the level of wear, teeth may be repaired by welding or by building up material in worn areas. For minor imperfections, grinding or machining can restore the gear tooth profile.
Hardening or Re-Hardening: If the teeth have lost hardness from wear, they may undergo re-hardening, especially for gears like those made from 8620 steel.
Re-Grinding and Re-Finishing: Helps correct tooth profile and pitch to ensure smooth meshing.
This refurbishment process helps gears perform like new, extending their service life while providing cost savings compared to complete replacement.
