Abstract: A novel gear well (200) for a crusher (1) may be characterized in that the recess (210) comprises a helical, non-uniform depth recess having a high point (212A) and a low point (212B). The gear well (200) may be further characterized in that rather than extending to a sharp corner transition (112) and then to an orthogonal sidewall (126), the floor (211) of the recess (210) may instead intersect or blend with the pinion clearance floor (222) adjacent the low point (212B). The helical, non-uniform depth recess (210) is preferably configured for improving the strength of a gear well (200) and/or configured for mitigating oil frothing within the gear well (200), without limitation.

Abstract: A vane having a profile capable of formation by pultrusion is disclosed. The vane can be used for removing liquids entrained in a gas stream. The vane includes a main curved section oriented generally parallel to the gas stream and curved to reorient the gas stream, the main curved section causing a first and a second change of direction of the gas stream; a first air pocket formed on a first side of the main curved section, the first air pocket sized and oriented into the gas stream where the gas stream first changes direction; and a second air pocket formed on a second side of the main curved section, the second air pocket smaller than the first air pocket and sized and oriented into the gas stream where the gas stream makes the second direction change.
