Publication number: 20180155898Abstract: A method of manufacturing a bucket by casting includes determining a volumetric capacity of the bucket. A modular mold assembly is configured by selecting a cope box and a drag box from multiple cope boxes and drag boxes based on the volumetric capacity of the bucket. Further, a first core is selected from multiple first cores based on the volumetric capacity of the bucket. The cope box, the first core, a second core, and the drag box are assembled such that the cope box, the first core, the second core, and the drag box together define a bucket-shaped mold cavity. A volume of the mold cavity depends on the selection of the cope box, the first core, and the drag box. A molten material is poured in the mold cavity and the cast bucket is removed after solidification of the molten material from the modular mold assembly.Type: ApplicationFiled: December 7, 2016Publication date: June 7, 2018Applicant: Caterpillar Inc.Inventors: Kadirvel Muthusamy, Gopalakrishnan Kanniappan, Ashok Rajendran

Patent number: 9896824Abstract: A wear plate assembly for a ground engaging system. The wear plate assembly includes a wear plate, a connection plate, and a lock cavity. The wear plate has a back surface and a front surface spaced from the back surface along a first direction. The connection plate extends from the front surface at least partially in the first direction. The connection plate has an inner surface and an outer surface spaced from the inner surface along a second direction. The lock cavity is formed by the connection plate. The lock cavity extends from a first opening that opens to the inner surface to a second opening that opens to the outer surface. The first opening has a first diameter and the second opening has a second diameter that is smaller than the first diameter.Type: GrantFiled: August 24, 2015Date of Patent: February 20, 2018Assignee: Caterpillar Inc.Inventors: Gopalakrishnan Kanniappan, Kadirvel Muthusamy, Venkatesh Madeshi, Gregory Seljestad, Anuop Udayakumar, Ashok Rajendran
