ABSTRACT:
An assembly (10) by which to effect incremental adjustments to the end play, or preloading, to a bearing set (12). Relatively rotatable first and second ring means (25 and 35) have contiguously juxtaposed and interacting ramp surfaces (29 and 36). In addition, the first ring means is operatively secured to the housing (14) in which the bearing set is supported in such a manner as to preclude rotation of the first ring means (25) with respect to the housing (14). A tang (30) presented from the first ring means (25) may interact with a slot (31) in the housing (14) to secure the first ring means (25) against rotation. The second ring means (35) is selectively rotatable with respect to the first ring means (25) to effect axial translation of the first ring means (25) by virtue of the interaction between said opposed, contiguously juxtaposed ramp surfaces (53) and 54). A latch plate (40) is disposed in proximity to the second ring means (35), and a tang (41) is also operative between the latch plate (40) and the housing (14) tro preclude rotation of the latch plate (40). A vernier locking means (45) is incrementally interactive between the latch plate (40) and the second ring means (35) selectively to secure the second ring means (35) against rotation and thereby secure the first lock ring (25) against axial translation.
