发明名称 Shaft liner assembly
摘要 A shaft liner assembly has a series of layers of arcuate segments, the segments in each layer forming a circle, and each side edge portion of each segment being outwardly reversely bent. A series of connecting brackets each have a longitudinally-extending base portion with wing portions extending from opposite sides thereof and inclined towards one another, each bracket being in sliding engagement with adjacent reversely bent portions of respective laterally adjacent segments in two vertically adjacent layers of segments. The wing portions of each connecting bracket are on the opposite side of the respective reversely bent portions of the segments to the base portion to secure laterally and verticaly adjacent segments together.
