BEARING PRE-LOAD SPRING WITH A VISCOELASTIC BODY COATING LAYER COMPRISING A VISCOELASTIC BODY COATING LAYER PREVENTING THE GENERATION OF NOISE

摘要

PURPOSE: A bearing pre-load spring with a viscoelastic body coating layer is provided to form a viscoelastic body coating layer in a bearing pre-load spring, thereby minimizing the vibration of the bearing pre-load spring.;CONSTITUTION: A bearing pre-load spring with a viscoelastic body coating layer comprises a pre-load spring(500) and a viscoelastic body coating layer(510). The pre-load spring is imposed in between a first bearing(200) and a second bearing(210), and upper case(100) and a lower case, thereby pre-loading the first and second bearings. It is allowed in between the first bearing(200), the second bearing(210), the upper case(100) and lower case(110) and the preloading spring pre-loads the first bearing and the second bearing. The viscoelastic body coating layer is formed in the exterior of the pre-load spring.;COPYRIGHT KIPO 2012
