IDLER ROLLER AND THE MANUFACTURE OF SUCH AN IDLER ROLLER |
摘要 |
The invention relates to an idler roller particularly for conveyor belt support and comprises a prefabricated core member about which is moulded an abrasion and impact resistant load bearing synthetic plastic shell. The shell includes a tubular load bearing wall and integral side walls for the accommodation of bearings which receive the idler shaft. By the utilisation of a relatively inexpensive core which does not require to possess load bearing properties, and utilising this core as a former about which the load bearing shell is moulded, a satisfactory idler roller structure can be constructed relatively inexpensively. The shell should be moulded from a non-foamed polyurethane elastomer material to give high quality abrasion resistance coupled with impact resistance. |
