The test beds for gear transmissions tests, enable the simulation of real contact conditions, generated on the gear teeth mesh and its behaviour evaluation, under established conditions, reliably fixed and monitored, such as: speed, torque, lubricant temperature, and others. These tests are used for lubrication analysis, wear and major destructive phenomena with negative influence on the gears life. This paper present the design of two test rigs for spur gears assessment, focusing the Contact Fatigue Strength and bending tests, which are the two main design criteria applying to the gears transmissions. These machines allow the behavior evaluation about such phenomena of different materials types, lubricants, additives, geometry modification, and other issues affecting the gears performance. It also establishes a test procedure, and just provides all planes for the machine manufacture and test specimens.

“…Scuffing performance has been measured using many different experimental techniques including the four ball [11], block on ring [21], Amsler [22], Ryder [23], IAE [24] and FZG [9]. Some of these tests employ pure sliding conditions [11,21] and others mixed rolling-sliding [9,23,24]. These techniques have several problems for studying scuffing as discussed in some detail by Peng et al [15].…”

In-Situ Observation of the Effect of the Tribofilm Growth on Scuffing in Rolling-Sliding Contact

General reductions in lubricant viscosities in many machine components mean that the role of lubricant additives in forming tribofilms has become increasingly important to provide adequate surface protection against scuffing. However, the relationship between scuffing and the formation and removal of tribofilms has not been systematically demonstrated. In this study, a step-sliding speed scuffing test based on contra-rotation using MTM-SLIM and ETM-SLIM has been employed to observe concurrently tribofilm thickness and the onset of scuffing. The initial sliding speed used was found to significantly affect scuffing performance since it determines the extent to which a tribofilm can form before critical sliding speed conditions are reached. In general, additives that formed thicker tribofilms, especially ZDDPs and triphenyl phosphate, gave effective protection against scuffing, though their protective tribofilms were progressively removed at higher sliding speeds, eventually resulting in scuffing.
