Method of construction of composite pulleys and the resulting pulley assembly

摘要

A composite pulley assembly comprises a plurality of individual disc pulleys (1) spaced apart by spacers (6) and connected together between end flanges (7 and 8) by means of bolts (13) passing through bores (17 and 12) in the outer end flange (7) and pulleys (1) respectively. The bolts (13) are screwed into threaded bores (20) in butt end flange (8) which comprises interengaging inner and outer annular members (9 and 10) provided with tapering cooperating surfaces. IMAGE
