摘要： A cartridge includes a body, an aperture extending through the body sized to receive a pivot pin, and a spherical bushing disposed within the body. The cartridge also includes a first internal seal disposed axially on one side of the bushing and a second internal seal disposed axially on an opposite side of the bushing. The cartridge also includes an end cap disposed at least partially within the aperture that abuts the bushing and prevents the bushing from moving axially in a first direction within the aperture.

摘要： A rope shovel has a boom and a hoist rope. The boom has a first end and a second end. The hoist rope extends over the second end of the boom. A digging assembly for the rope shovel includes a shaft, an elongated member supported for movement relative to the boom, an attachment, and a drive link. The shaft is positioned between the first end and the second end of the boom and transverse to the boom, and the shaft includes at least one pinion gear. The elongated member includes a first end and a second end. The attachment is coupled to the first end of the elongated member and is configured to be coupled to the hoist rope. The drive link includes a rack engaging the pinion gear of the transverse shaft such that rotation of the pinion gear moves the drive link and actuates the attachment.

摘要： A snubber for a machine is provided. The snubber includes a frame that is mounted on an implement of the machine, a shaft that is operatively coupled to a movable component of the implement and a housing that is coupled to the shaft and rotatably received within the frame. The housing defines a cavity that is configured to store a fluid therein in a sealed manner. The snubber also includes at least one brake disc disposed within the housing and configured to rotate with the shaft and at least one brake pad disposed within the housing and configured to frictionally engage with the at least one brake disc to oppose rotational movement of the housing relative to the frame. The fluid is configured to at least partly remove heat generated due to the frictional engagement between the at least one brake disc and the at least one brake pad.

摘要： A hydraulic system for a power shovel is disclosed. The hydraulic system may have a cylinder operatively connectable to a dipper door of the power shovel, a reservoir located at and fluidly connected to the cylinder, and an accumulator located at and fluidly connected to the cylinder in parallel with the reservoir. The hydraulic system may further have a control valve disposed between the cylinder, the reservoir, and the accumulator. The control valve may be movable to selectively direct fluid from the cylinder into the accumulator and fluid from the reservoir into the cylinder.
