Title:
POWER TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/118324
Kind Code:
A1
Abstract:
A bolt hole (34a) having a female threaded section at the closed end is formed in an input cone (34), and a bolt receiving section (34b) is formed in the vicinity of the open end of the bolt hole (34a). A bolt (35) is fitted and inserted into the bolt hole (34a), and a male threaded section at the tip of the bolt (35) is threadably engaged with the female threaded section of the bolt hole (34a), resulting in a compressive force being made to act on the smaller outside diameter portion of the input cone (34). In other words, the compressive force is made to act on the smaller outside diameter section, where the strength is lowest in the input cone (34). Therefore, it is possible to reinforce the region of the input cone (34) where the strength is most insufficient and where reinforcement is needed most. Consequently, as compared with a case where the bolt (35) is not caused to make any compressive force act on the smaller outside diameter portion of the input cone (34), it is possible to reduce the degree of deformation of the input cone (34), said deformation being generated by constriction pressure caused by a constriction pressure adjustment mechanism (50).
