Slewing Ring Gear

1.Product Introduction: Slewing bearings with an integrated gear ring structure can directly connect with the motor gears to transmit power without the need for additional transmission components, suitable for large equipment that requires active slewing.
2.Structure Type: The inner and outer rings of the slewing bearing are machined with straight or helical teeth (module 2 - 12) on the circumference. The gears are carburized and quenched. The core consists of the inner and outer rings, steel balls or rollers, and cages, and is integrally forged.
3.Size Range: Outer ring diameter: 500 - 3500mm, gear ring width: 20 - 80mm, height: 30 - 100mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: Tower cranes (slewing drives), portal cranes, large amusement equipment (slewing of observation wheels), port loading and unloading machinery.
6.Key Inspection Items: Gear pitch error, depth of carburized layer, tooth surface hardness (HRC58 - 62).
