VIBRATION DAMPING STRUCTURE FOR MOTOR BEARING SYSTEM

摘要

A vibration damping structure for a motor bearing system includes a washer (8), an end cover (9), a bearing (10), a rotary shaft (11), an axial retaining ring (12) and a cap (13). The bearing is mounted in a bearing seat (20) of the end cover (9). The rotary shaft (11) is supported by the bearing (10). The washer (8) is mounted on the rotary shaft (11) and disposed at one side of the bearing (10). The cap (13) is disposed outside the washer (8) and mounted on the end cover (9). The vibration damping structure further includes a vibration damping washer (14) mounted on the end cover (9). The washer (8) is disposed between the vibration damping washer (14) and the axial retaining ring (12). The vibration damping washer (14) separates the washer (8) from the bearing (10) and the end surface (19) of the bearing seat (20) axially. The vibration damping structure can reduce vibrations through buffering and have a longer operating life.
