Arrangement structure of shaft and hub used in automobile applications, has shaft-hub connection portion for connecting shaft and hub such that two portions of teeth of shaft are extended on surface of shaft at specific angle

摘要

The arrangement structure has a shaft-hub connection portion (5) for connecting a shaft (6) and a hub (4). The shaft is axially extended from the hub, such that teeth (2) of shaft are engaged with teeth (1) of hub to transmit rotational torque. Tooth flanks (8a,8b) of teeth of the hub are extended rectilinearly. Two portions (12,13) of teeth of the shaft are extended on surface of shaft at specific angle (16).
