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.
