The structure of main components of deep groove ball bearing features

Deep groove ball bearings due to the different purposes and working conditions, its structure change there are many, but the basic structure is composed of inner ring and outer ring, rolling body ( Steel ball) And keep the frame of four parts. A, inner ring ( Also known as inner sleeve or inner ring) 。 Usually fixed on the shaft neck, inner ring together with the axis rotation. On inner ring surface for steel ball or roller rolling groove, called inside groove or inner raceway. Second, the outer ring ( Also known as the coat or outer ring) 。 Usually fixed on the bearing seat or on the shell of the machine, the effect of rolling element bearing steel ball. Has for steel ball or roller in the outer surface of the rolling groove, called inside groove or inner raceway. Third, rolling body ( Steel ball) 。 Each deep groove ball bearings are fitted with a group or several groups of rolling body, between inner ring and outer ring, rolling the heritability of the role. Roller is the load components, and its shape, size and quantity determines the capacity of axial load of each performance of high-speed operation. Four, cage ( Also known as the retainer or isolator) 。 Rolling element bearing in the evenly separated from each other, make each roller rolling normally between inner ring and outer ring. In addition, the cage has the guide roller motion, improve internal bearing lubrication condition, and prevent rolling body falls off, and so on. In thrust ball bearing, cooperate with axial ring is called shaft circle, cooperate with bearing or machine shell ring of the best-selling, shaft ring and seat generally referred to as the gasket. In addition to the above four parts, all kinds of different structure of the bearing and other parts matching. For example, rivets, dust cover, sealing ring, lock washer with, collar and sleeves, etc. On an article: how to choose scientific bearing next up: the precision of the rolling bearing level
