Publication number: 20230272601Abstract: The invention relates to an adapter and a wear element of a shovel of an earth moving machine attached to one another by means of a pin, wherein the pin is positioned at a point such that, as there is relative rotation between the wear element and the adapter, due to the application of both a force according to direction Y applied on a point B1 and directed towards a point B2 and a force according to direction Y applied on point B2 and directed towards point B1, the support surfaces of the adapter and of the wear element contact one another before the pin is subjected to stresses. The stresses the pin must withstand are thereby reduced.Type: ApplicationFiled: June 10, 2021Publication date: August 31, 2023Inventors: RAUL TORRES MONTALVO, Albert GIMENO TORDERA, Fermin SÁNCHEZ GUISADO

Patent number: 10294637Abstract: A tooth for attachment to the lip of a bucket of a working machine via an adaptor, having a cavity for receiving a portion of the adaptor, the cavity extending between first and second opposed outer working surfaces (12, 14) from an open end (104) to a bottom end (105); the cavity (103) delimited by an inner wall (102) having first and second facing inner walls (106, 107), and opposing side walls (108), interconnecting the first and second inner walls (106, 107). The cavity defines a back portion (BP) along the Y axis and between the plane spanned by the X and Z axes and the open end of the cavity, a front portion (FP) along the Y axis and between the plane spanned by the X and Z axes and the bottom end of the cavity; and a stepped portion (SP), interconnecting the back portion and the front portion.Type: GrantFiled: April 29, 2014Date of Patent: May 21, 2019Assignee: Volvo Construction Equipment ABInventors: Francisco Perez Soria, Fermin Sanchez Guisado, Javier Rol Corredor, Jorge Triginer Boixeda
