.... Their tooth forms are similar to those of spur and helical gears except that the teeth point inward toward the center of the gear. Common applications for internal gears include rear drives for heavy vehicles, planetary gears, and speed-reducing devices. Internal gears are sometimes used in compact designs...

... unnecessary for maximum surface hardness and that carbon steels could be used in place of alloy steels. Caterpillar subsequently purchased a 500 kW, 9.6 kHz motor generator set for induction hardening their final drive gear with a 642 mm (25.7 in.) diameter by a 125 mm (5 in.) wide face. In an article...

... of 40 to 50 mm (1.57 to 1.97 in.) thickness, depending on the size of the rollers. The three scrapers positioned in between the rollers push the sand towards the rotating rollers, blending the sand, bentonite clay, and water. The central roller carrier is driven by a reduction gear drive and motor, like...

... of friction, because without sliding friction, these surfaces would not wear. The need to control friction is the driving force behind its study. In many cases low friction is desired (bearings, gears, materials processing operations), and sometimes, high friction is the goal (brakes, clutches, screw...

..., as in aircraft landing gear, beryllium coppers such as ASTM International B194 alloy C17200 age hardened to 40 HRC are used lubricated against hard steel. If galling is an issue, aluminum bronzes such as ASTM International B148 alloy C95300 (86 Cu, 1 Fe, 10 Al) have shown galling resistance against hard steels...

... that traction is a force tending to drive, and friction is a force tending to retard motion. The high-speed reciprocating test (SRV/HFRR) is a reciprocating pin-on-flat, but the oscillation frequency is high and the stroke is small, usually only 1 mm. These tests will be described in detail in Chapter 5...
