Support device with interchangeable wearing members for a rotary part such as a tubular furnace

摘要

To facilitate the replacement of wearing parts such as rollers (36, 42) on which is received a rotary part (10), a support device (12) is designed in such a way that the wearing parts belong to an interchangeable support member (30) interposed between a fixed body (16) and the rotary part (10). Replacement takes place by coupling to the interchangeable support member (30) a replacement support member (30'), using linking structures (56), and by rotating the assembly of the two members (30, 30') by 180 DEG about the axis (14) of the rotary part. The two members are then uncoupled and the replacement support member linked to the fixed body (16) by locking structures (50).
