Thin metal ring for metal belt type nonstep variable-speed transmission

摘要

Thin metal rings for a nonstep variable-speed transmission including a drive pulley and a driven pulley having variable effective diameters to change speed change ratio. The thin metal rings (30) are layered to form layered ring structures (31), a plurality of blocks (32) are arranged along and supported on the layered ring structures (31) to form an endless metal belt (15), and the endless metal belt (15) is extended between the drive and the driven pulley.
