Abstract: Experimental results on anti-seizing property of spiroid gearing with a combination of steel-steel materials had been presented. Goal of investigations is to obtain scuffing criterion and to build on its base method for calculating spiroid gears. This will to establish scuffing conditions, so that even at the design stage to prevent it. Thus, there will be the possibility of manufacturing spiroid gears of more efficient materials that increase their prevalence and might better realize the benefits of spiroid gears to other gears worm class. Investigations were conducted on a laboratory-scale plant. Its basis is the disk-roller friction unit, which is a physical model spiroid gear. Scuffing criterion used for evaluation anti-seizing property of spiroid gears had been offered for research. Procured nondimensional criterion takes into account two groups of factors: temperature effect and load carrying capacity of the oil film. The test results are received characteristic curves friction coefficient of sliding velocities, nominal pressures and temperature for spiroid gearing with a combination of steel-steel materials. Scufing criterion received characteristic of nominal pressures to step sliding velocities and temperature had been brought.
