GANG TYPE ANGLE HEAD FOR A SHELF, CAPABLE OF MAINTAINING PRE-PRESSURE OF A BEARING BY PREVENTING THE VIBRATION OF A SHAFT OF THE BEARING

摘要

PURPOSE: A gang type angle head for a shelf is provided to maintain pre-pressure of a first bearing and a second bearing even if a spin rotates at a high speed, by fixing an inside diameter unit and an outside diameter of the first and second bearings in a shaft direction.;CONSTITUTION: A gang type angle head for a shelf comprises a first bearing(45) and a second bearing(50). An outer diameter unit(45a) of the first bearing is fixed by a first protrusion(31) and a spindle cap(75), and an inner diameter unit(45b) is fixed by a collar(70) and a body cap(60). The acute angle of the first bearing is fixed so that the pre-pressure of the first bearing can be regularly formed. An outer diameter unit(50a) of the second bearing is fixed by a second protrusion(32) and a support ring(65), and an inner diameter unit(50b) is fixed by a support protrusion(56) and a flange(80). The acute angle of the second bearing is fixed so that the pre-pressure of the second bearing can be regularly formed. Therefore, a spindle(55) can rotate at a high speed.;COPYRIGHT KIPO 2013
