摘要： A damper for dampening rotation of a dipper door relative to a dipper body of a mining shovel includes a shaft, an arm, and a high pressure fluid seal. The shaft supported for rotation about a shaft axis, and rotation of the shaft is dampened by fluid in an enclosed chamber. The high pressure fluid seal engages an outer surface of the shaft at a position between the first end of the shaft and the second end of the shaft. The high pressure fluid seal engages an outer surface of the shaft and includes a low pressure side and a high pressure side adjacent a shaft cavity. The arm includes a first end coupled to the first end of the shaft, and a second end coupled to the dipper door or the dipper body such that rotation of the dipper door drives the arm to rotate the shaft.

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 dipper having an inlet and an outlet. The dipper includes a front wall and an opposite back wall extending between the inlet and the outlet. The front wall has a substantially linear inner surface between the inlet and the outlet. The dipper further includes two side walls connected between the front wall and the back wall and extending between the inlet and the outlet. Further, the dipper has a lip coupled to the front wall and extending outwardly from the inlet in a direction away from the outlet, the lip having a lip inner surface arranged generally parallel with the substantially linear inner surface of the front wall.

摘要： A dipper for a mining shovel includes a back wall, a first side wall extending from the back wall, a second side wall extending from the back wall, a front wall disposed opposite the back wall and extending between the first and second side walls, and a dipper door pivotally coupled to a bottom end of the dipper. The dipper door is movable between a latched and an unlatched position relative to the dipper. The dipper door is angled relative to the front wall at an acute angle when the dipper door is in the latched position.
