TL;DR: In this paper, an investigation into the effect of fiber reinforcement on the friction and wear of PA66 in rolling-sliding contact is reported, and three types of short fiber composites were examined with the composites running against identical materials in a twin disc machine.

TL;DR: In this paper, an extensive investigation of polymer gear (acetal and nylon) friction and wear behavior was presented. But the most interesting observation from the experimental work is the significant difference in wear behaviour when running acteal against nylon gears, especially the low wear rate when acetal is used as the driver gear.

TL;DR: In this article, the behavior of polymers and polymeric composites in non-conformal contact is discussed and it is shown that friction-generated heat has a major influence on the materials' performance and that the use of acetal in spur gears is controlled by the temperature rise.

TL;DR: In this article, the wear behavior of three typical gear materials is examined and it is shown that the wear characteristics differ greatly and that there is a sharp rise in wear as the transmitted torque is increased, effectively limiting the torque that can be transmitted by an Acetal gear pair.

TL;DR: In this article, the authors examined the design of hydrostatically balanced bearings as used in the slippers of high pressure axial piston pumps, and outline a design procedure whereby the slipper behaviour, minimum film thickness and loss of high-pressure fluid can be estimated.
