Abstract
A bearing assembly for a driveshaft that facilitates a swinging movement of a frame of a dragline with respect to a base of the dragline. The bearing assembly includes a housing, a spherical bearing, and a thrust bearing. The housing is fixedly engageable with the frame and defines a cavity to provide rotatable passage to the driveshaft therethrough. The spherical bearing is engageable with each of the housing and the driveshaft for journaling the driveshaft in the cavity and facilitating a rotation of the driveshaft about a longitudinal axis and an angulation of the driveshaft with respect to a reference axis. The thrust bearing is configured to be supported against each of the driveshaft and the housing to accommodate the angulation of the driveshaft and an axial load passing along the longitudinal axis away from the spherical bearing onto either of the housing or the frame.
