摘要：Various embodiments relate to a bearing assembly including a support ringconfigured to reduce thermal warping under operational temperature conditions, a

bearing apparatus that may utilize such a thrust-bearing assembly, and applications thatincorporate the disclosed bearing apparatuses such as downhole motors in subterraneandrilling systems, directional drilling systems, and many other apparatuses. In anembodiment, a bearing assembly includes a plurality of superhard bearing elementsdistributed circumferentially about an axis. The thrust-bearing assembly further includesa support ring having the plurality of superhard bearing elements mounted thereto. Thesupport ring includes at least one thermal-warping-reducing feature configured toreduce a radial moment, compared to if the at least one thermal-warping-reducingfeature were absent from the support ring, which is thermally induced in the support ringwhen the support ring and the plurality of superhard bearing elements are exposed tooperational temperature conditions.
