Analysis of Composite Worm Gear Ring Wear and Lubrication Conditions Due to Torque Testing

The unknown thickness of wear between the 3D-printed worm gear ring composite and the steel worm in the reduction gear of the torque testing machine with various lubrication conditions is a problem. Research methods include removing a new brass worm gear ring, 3D scanning, modifying cloud data, creating working drawings, 3D printing composites (worm gear rings) of Onyx and Onyx+10%CF materials, installing the composite on holder steel wheels, placing the steel worm axle into the reduction gear, torque testing with three lubrication conditions dry, SAE 10W-30 Oil, and Castrol Lithium Grease (CLG) with 180 steel specimens, and preparing Scanning Electron Microscope (SEM) photograph specimens. The results of the research are wear between steel tooth with Onyx composite from largest to smallest value in oil worth 0.1300 mm, dry worth 0.0943 mm, and CLG worth 0.0650 mm; wear between the Onyx+10%CF composite on the worm gear ring from the largest to the smallest value for oil worth 0.0970 mm, dry worth 0.0630 mm, and CLG worth 0.0030 mm; and there is an interaction between the composite and the oil which changes the color of the used oil to become darker.
