Differential gear used in vehicle, has insertion elements that are fitted to drive gears to form guide structure, and are supported by bearing rings of roller bearings

摘要

The differential gear has roller bearings (L1, L2) for supporting a planet carrier (3) rotated around a rotational axis (X). The drive gears (1,2) are arranged coaxially to rotational axis and equipped with drive gear teeth (1a,2a). A circulation planetary arrangement (P) has circulation planetary gears (P1, P2) that are coupled with drive gears in opposite directions, and rotated relative to planetary gear shafts (XP1, XP2). The insertion elements (E1,E2) are fitted to drive gears to form guide structure and supported by bearing rings (L1i, L1a, L2i, L2a) of roller bearings.
