Abstract
A support apparatus for a shaft system includes a first shaft, a second shaft, and a bearing arranged between the first shaft and the second shaft. The first shaft is sleeved at an outer peripheral side of the second shaft and is able to rotate relative to the second shaft by means of the bearing. The support apparatus includes: shaft end support members, at least a portion of the shaft end support members being rotatably supported in an axial direction at an outer side of a shaft end face of a first end of the second shaft; and connection assemblies. The connection assemblies in the axial direction of the shaft system are used for being connected between a first end of the first shaft and the shaft end support members.
