Patent number: 10837487Abstract: A bearing assembly is disclosed. The bearing assembly includes a first race. Further, the bearing assembly includes a second race disposed concentric to the first race, where the second race has a radius that changes along an axial length of the bearing assembly. The bearing assembly also includes a housing disposed around the second race and operatively coupled to the second race. Moreover, the bearing assembly includes a plurality of support structures configured to detachably couple the second race to the housing, where the plurality of support structures are configured to disengage the second race from the housing to allow motion of the second race when a torque on the second race is greater than a threshold torque value.Type: GrantFiled: March 27, 2019Date of Patent: November 17, 2020Assignee: Transportation IP Holdings, LLCInventors: Mandyam Rangayan Sridhar, Ravindra Shankar Ganiger, Dinesh R. Rakwal, Ajith Kuttannair Kumar, Bret Dwayne Worden

Patent number: 10480474Abstract: A method and system for determining remaining useful life of an in-use injector of a reciprocating engine is disclosed. The method includes determining nozzle wear relationship data for different duty cycles of the in-use injector, and using the nozzle wear relationship data together with operating parameters for the reciprocating engine, and emission relationship data to determine actual emission levels for the in-use injector based on the wear relationship data and the emission relationship data. The method and system further include determining remaining useful life of the in-use injector based on actual emission levels and the nozzle wear relationship data; and controlling an operation of the reciprocating engine based on the actual emission levels.Type: GrantFiled: April 6, 2018Date of Patent: November 19, 2019Assignee: GE Global Sourcing LLCInventors: Amit Chandrakar, Rahul Srinivas Prabhu, Mandyam Rangayan Sridhar, Manoj Prakash Gokhale

Publication number: 20190056291Abstract: A method for estimating life of a piston ring includes obtaining a reference profile of the piston ring. The reference profile comprises a plurality of reference fiducials. The method further includes receiving a measured profile of the piston ring. The measured profile comprises a plurality of measured fiducials. The method further includes aligning the measured profile with the reference profile based on one or more of the plurality of reference fiducials and one or more of the plurality of measured fiducials. The method also includes determining one or more wear parameters based on the aligned measured profile and the reference profile. The method also includes generating a wear model based on the one or more wear parameters. The method also includes estimating a life of the piston ring based on the wear model.Type: ApplicationFiled: July 16, 2018Publication date: February 21, 2019Inventors: Mandyam Rangayan SRIDHAR, Savio Sebastian KATHAYANATT, Harsha Kikkari ANANTHA RAO, Souvik MATH, Praveen HOLANI
