Product Description

Heavy load worm drive slewing gear reduction for mounted truck crane drilling rig,excavator  and other rotation slewing drive

Coresun Drive slewing drives worm gear can be widely used for grapple machines, Aerial platform, forklift ,mobile crane ,Drilling Rig ,solar tracking system, wind turbine and satellite dish.Those products are designed for long life, working in hard environmental conditions.Hourglass worm shaft is used in each sized slewing drive for better efficiency, more torque and smoother rotation by multiple tooth contact with the slewing rings

Slewing drives are perfect for situations requiring both load-holding and rotational torque from the same gearbox.Ttypical applications include solar trackers, wind turbines, satellite and radar dishes, truck cranes, man lifts, utility equipment, hydraulic equipment attachments, oil tool equipment, tire handlers, digger derricks, and automotive lifts.

This increased tooth engagement results in greater strength, efficiency and durability.The slewing drive uses standard worm technology in which the worm on the horizontal The speed ratio of the shaft depends on the relationship between the number of threads on the worm and the number of teeth in the worm gear or gear.The specifications of the drive and gear depend on the material of the gear. However, most of the drives and gears typically used consist of steel and phosphor bronze. According to a wide range of tests,chilled nickel-phosphorus bronze ranks first in terms of Wear resistance and deformability

WH series for heavy duty rotary drive.The surface adopts QPQ treatment process, which can not only increase the surface hardness of the product, but also ensure its wear resistance and corrosion resistance.

On the basis of the original product, 8 bolts are added at both ends of the worm to effectively prevent the worm from being pulled out due to the excessive axial impact force.

Different from the traditional 42CrMo worm material, carbon steel is added to ensure that the worm can bear the input torque of 600-1000N. M

WH14 slewing drive rotary table is widely used in aerial work platform, roadheader, rotating equipment and automatic assembly line.
