Patent number: 11994128Abstract: A compressor may include first and second scroll members, first and second bearings, and first and second Oldham couplings. The scroll members define compression pockets. The first bearing may define a first rotational axis about which the first scroll member rotates. The second bearing may support the second scroll member for rotation about a second rotational axis that is offset from the first rotational axis. The first Oldham coupling may include a first body and a plurality of first keys extending from the first body. The first keys may engage slots formed in the second scroll member. The second Oldham coupling is separate and distinct from the first Oldham coupling. The second Oldham coupling may include a second body and a plurality of second keys extending from the second body. The second keys may engage slots formed in a surface that rotates about the first rotational axis.Type: GrantFiled: March 6, 2023Date of Patent: May 28, 2024Assignee: Copeland LPInventors: Kirill M.

Patent number: 11959477Abstract: A bearing system for a compressor including an unloader at least partially received within a recess of a driveshaft. The unloader includes an outer surface that is engaged with a bearing. An inner surface of the unloader is curved such that the unloader is pivotable relative to the driveshaft unload forces on bearing caused by deflection of the driveshaft.Type: GrantFiled: September 26, 2022Date of Patent: April 16, 2024Assignee: Copeland LPInventors: Kirill Michailovich Ignatiev, Robert Christopher Stover, Mikhail A.

Publication number: 20230313796Abstract: A compressor includes a shell, a first compression member, a bearing housing and a second compression member. The first compression member is rotatable relative to the shell about a first axis. The bearing housing is coupled to the first compression member and rotatable relative to the shell about the first axis. The bearing housing includes a first pin that extends therefrom. The second compression member is rotatable relative to the shell about a second axis. The second compression member includes a base plate and an arcuate-shaped first pin pocket. The first pin pocket is formed in the base plate and receives the first pin. The first compression member is moveable between a first position in which the first pin is engaged with a surface of the first pin pocket and a second position in which the first pin is disengaged from the surface of the first pin pocket.Type: ApplicationFiled: June 5, 2023Publication date: October 5, 2023Applicant: Emerson Climate Technologies, Inc.Inventors: Kirill M.

Publication number: 20230147568Abstract: A compressor includes a compression mechanism, a driveshaft, and a motor. The compression mechanism is configured to compress a fluid to a discharge pressure. The motor is configured to rotate the driveshaft. The driveshaft is engaged with the compression mechanism and is fixed to rotate with at least a portion of the compression mechanism. The driveshaft includes a longitudinal aperture configured to receive the fluid at a suction pressure, and includes a flange that receives at least a portion of the compression mechanism. The flange and the compression mechanism define a fluid passage therebetween. The fluid at suction pressure is received within the fluid passage from the longitudinal aperture in the driveshaft.Type: ApplicationFiled: November 5, 2021Publication date: May 11, 2023Applicant: Emerson Climate Technologies, Inc.Inventors: Kirill M.

Patent number: 11015598Abstract: A compressor includes a non-orbiting scroll, an orbiting scroll, a driveshaft, a bearing housing and a bushing. The non-orbiting scroll includes a first spiral wrap. The orbiting scroll includes an end plate having a first side and a second side. The first side has a second spiral wrap that extends therefrom and meshingly engages with the first spiral wrap of the non-orbiting scroll. The second side has a hub extending therefrom. The driveshaft has a crankpin that is received in the hub and that drives the orbiting scroll. The bushing includes a first member and a second member. The first member is disposed within the hub of the orbiting scroll between the hub and the crankpin of the driveshaft.
