In addition, our tooth surface adopts segmented induction hardening, which avoids the soft belt docking problem easily caused by traditional full-circle quenching and ensures the 360-degree hardness of the gear."],"comparison_points_description1":["The stress concentration of the tooth root was eliminated by optimizing the radius of the tooth root fillet and strengthening the tooth root by shot peening. With the high toughness of 42CrMo material, the problem of tooth breakage caused by excessive instantaneous impact load is completely solved when the excavator is digging hard rock or strong crushing."],"comparison_points_description2":["In view of the problem of sticking caused by the peeling of the old bearing raceway, we adopted the optimized raceway curvature design and high-precision steel ball selection. This not only reduces the friction heat between the raceway and the steel ball, but also effectively prevents the metal debris generated by fretting wear from jamming the raceway, and solves the problem of unsmooth rotation."],"comparison_points_description3":["In view of the oil leakage problem caused by the aging of the sealing strip, the labyrinth groove combined with the double lip seal structure is adopted.
