    Abstract: Embodiments of a thrust bearing that may be used with a crankshaft of a HVAC compressor, particularly a HVAC compressor with a vertical or near-vertical placed crankshaft (e.g. a scroll compressor) are provided. The thrust bearing may generally include a bearing header and an insert. The insert may include an insert surface, which is configured to interact with a shaft surface of the crankshaft. The insert surface of the insert may include surface features that may help create flow behavior of the lubricant by a relative motion between the shaft surface of the crankshaft and the insert surface of the insert. The flow behavior of the lubricant may help separate the insert surface of the insert and the shaft surface of the crankshaft by the lubricant in operation to form the bearing, such as a hydrodynamic bearing.

    Abstract translation: 提供了可以与HVAC压缩机的曲轴，特别是具有竖直或近垂直放置的曲轴（例如涡旋压缩机）的HVAC压缩机一起使用的推力轴承的实施例。 推力轴承通常可以包括轴承头和插入件。 插入件可以包括插入表面，其被配置为与曲轴的轴表面相互作用。 插入件的插入表面可以包括表面特征，其可以通过曲轴的轴表面和插入件的插入表面之间的相对运动来帮助产生润滑剂的流动特性。 润滑剂的流动特性可以有助于在操作中通过润滑剂将插入件的插入表面和曲轴的轴表面分离以形成诸如流体动力轴承的轴承。

    Abstract: A scroll compressor includes one or more stage of compression disposed within a compressor housing. One or more of the stages includes a stationary scroll member including a base and a generally spiral wrap extending from the base of the stationary scroll member. One or more of the stages further includes an orbiting, scroll member including a substantially circular base and a substantially spiral wrap extending from the base of the orbiting scroll member. A coupling is disposed between the first scroll member base and the second scroll member base and in surrounding relationship to the first and second scroll member spiral wraps. At least one stabilizing pad is disposed between the first scroll member base and the second scroll member base and in axial thrust force relationship with the coupling to at least partially prevent tipping of the second scroll member.
