Patent number: 10982672Abstract: A light-weight, high-strength compressor component is formed via additive manufacturing that has controlled stiffness and/or deflection levels. The component may have at least one interior region comprising a lattice structure that comprises a plurality of repeating cells. A solid surface is disposed over the lattice structure. The interior region comprises the lattice structure in the body portion of the light-weight, high-strength compressor component. The lattice structure may be used to globally or locally control stiffness and/or deflection levels of the compressor component. Additive manufacturing provides flexibility in forming compressor components with desirably improved strength-to-weight ratios while exhibiting high levels of control over stiffness and/or deflection. Methods of making such compressor components via additive manufacturing processes are also provided.Type: GrantFiled: December 1, 2016Date of Patent: April 20, 2021Assignee: Emerson Climate Technologies, Inc.Inventors: Marc J.

Patent number: 10974317Abstract: Methods for making a tribological bearing wear surface for a compressor component are provided. Such methods involve semi-solid metal casting, where an admixture of solid lubricant particles and a metal alloy material is heated to melt the metal alloy material, while the lubricant particles remain in a solid phase. The alloy material and solid lubricant have substantially different densities. The metal alloy material may be a copper, iron, or aluminum alloy, for example. The method further comprises mixing and cooling the admixture to form a semi-solid slurry admixture. Next, the method comprises introducing the semi-solid slurry admixture into a die. Finally, the semi-solid slurry admixture in the die is solidified to form a solid component having the solid lubricant particles homogenously distributed within a metal alloy material matrix, thus forming a metal matrix composite. Compressor components made from such methods are also provided.Type: GrantFiled: July 18, 2017Date of Patent: April 13, 2021Assignee: Emerson Climate Technologies, Inc.Inventors: Roxana E. L.

Patent number: 9957963Abstract: Scroll members for scroll compressors made from one or more near-net shaped powder metal processes, either wholly or partially fabricated together from sections. In certain variations, the involute scroll portion of the scroll member has a modified terminal end region. The terminal end region may include an as-sintered coupling feature comprising a tip component that forms a contact surface for contacting an opposing scroll member during compressor operation. The tip component can be a tip seal or a tip cap received by the as-sintered coupling feature. The tip cap may be sinter-bonded or otherwise coupled to the terminal end region. In other variations, a terminal end region may comprise a second material including a tribological material that forms a contact surface. Methods of making such scroll members for scroll compressors are also provided.Type: GrantFiled: September 26, 2014Date of Patent: May 1, 2018Assignee: Emerson Climate Technologies, Inc.Inventors: Robert C.

Publication number: 20150147012Abstract: Methods for improving bearing performance in compressors, especially for those that use high energy refrigerants or that have a high-side design, are provided. The compressor comprises a bearing that is substantially free of lead. The bearing comprises copper and at least one lubricant particle type selected from a group consisting of: molybdenum disulfide (MoS2), calcium fluoride (CaF2), tungsten disulfide (WS2), zinc sulfide (ZnS), hexagonal boron nitride, polytetrafluoroethylene (PTFE), carbon fiber, graphite, graphene, carbon nanotubes, carbon particles, thermoset polyimide, and combinations thereof. The compressor processes a high energy refrigerant and a lubricant oil comprising a sulfur-based additive. The sulfur-based additive reacts with the copper in the bearing to enhance lubricity and improve performance of the bearing in the compressor machine. Compressors having such features and improved bearing performance are also contemplated.Type: ApplicationFiled: November 24, 2014Publication date: May 28, 2015Inventor: Marc J. SCANCARELLO

Patent number: 8955220Abstract: Methods of forming scroll compressor components are provided. The methods include forming at least one component of a scroll member from a powder metallurgy technique and joining the component with another distinct component via a sinter-brazing process. For example, a baseplate having a spiral scroll involute is joined to a hub via a joint interface having brazing material to form a braze joint with superior quality. At least one component is formed from a powder metal material including carbon and at least one species that reacts with or binds carbon to prevent migration during brazing of the sinter-brazing heat process. Optionally, during the powder metallurgy process, an alloy with a lower concentration of carbon is selected, which may be incorporated into a crystal structure with the species that prevents carbon migration.Type: GrantFiled: March 10, 2010Date of Patent: February 17, 2015Assignee: Emerson Climate Technologies, Inc.Inventors: Marc J.
