Abstract
A bearing assembly is provided for supporting a shaft for rotation. The bearing assembly includes a housing, a bearing positioned in the housing and coupled to the shaft, and a mount coupled to the bearing and to the housing. The bearing is configured to support the shaft about an axis. The mount is movable relative to the housing, thereby allowing movement of the bearing relative to the housing.
Claims20
A bearing assembly for supporting a shaft for rotation, the bearing assembly comprising:
- a housing;
- a bearing positioned in the housing and coupled to the shaft, the bearing configured to support the shaft about an axis;
- and
- a mount coupled to the bearing and to the housing, the mount movable relative to the housing, thereby allowing multi-axial movement of the bearing relative to the housing.
A mount configured to support a bearing within a housing, the mount comprising:
- a first member including a mounting portion configured to be coupled to the bearing and a protruding portion extending from the mounting portion;
- a support configured to be secured relative to the housing, the support having an aperture extending therethrough, the protruding portion configured to extend through the aperture;
- and
- a second member coupled to an end of the protruding portion, the second member positioned on an opposite side of the support from the mounting portion.
An idler assembly for a mining machine, the idler assembly comprising:
- an idler shaft including a first end, a second end, and a shaft axis extending therebetween;
- a first bearing assembly supporting the first end of the idler shaft for rotation about the shaft axis, the first bearing assembly configured to support the idler shaft relative to a frame;
- and
- a second bearing assembly supporting the second end of the idler shaft for rotation about the shaft axis, the second bearing assembly configured to support the idler shaft relative to the frame,
- wherein at least one of the first bearing assembly and the second bearing assembly includes a housing, a bearing supported by the housing, and a mount configured to allow relative translational movement and rotational movement between the idler shaft and the housing.
