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 retainingring (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) ismountedon 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). Thevibration damping structure further includes a vibration damping washer (14)mounted on the end cover (9). The washer (8) is disposed between the vibrationdamping washer (14) and the axial retaining ring (12). The vibration dampingwasher (14) separates the washer (8) from the bearing (10) and the end surface(19) of the bearing seat (20) axially. The vibration damping structure canreducevibrations through buffering and have a longer operating life.
