The bearing type, ball type beauty bud is mechanical processing technology application

Type, ball type beauty bud is the bearing machining technology application the bud is the bearing is given priority to with miniature bearing under 22 mm outer diameter, as many as 8500 kinds of product model, in the face of high speed, low noise, low vibration, special environment, such as conditions of use, has the rich solution, product sales account for more than 60% of global market share. The page and the ball bearing is composed of outer ring, inner ring, rolling, rolling retainer, seal ( Dust cover) And spring coil of machining parts. Less than 30 mm outside diameter is called the micro and small ball bearing, is to ensure that the shaft of the rotating equipment with high precision requirements stable operation of the bearing parts and assembly in precision parts. Bud and the bearing is in the United States: the page and also known as a size bearing shaft, bearing is processed from rolling groove in the shaft directly, make up the role of the inner ring, bearing and shaft and shaft sleeve combined with one of a kind of special structure bearing. Mainly used in the camera lens barrel. And often on the bearing assembly 2 ball bearing components, compared to the rotating accuracy are improved greatly. The use of ultra precision machining technology, the bud and the ball bearing is basically composed of outer ring, inner ring, rolling body, cage, seal ( Dustproof set) And spring coil, etc. Decide the bud and the precision of ball bearing is the key is 'ball rolling between the outer and inner ring groove of the roundness, =) and the theory of roundness error 'And' ball sphericity ( =) and the theory of the sphericity error 'And' material 'components. Only completely improve all the above elements of quality requirements, to achieve a higher precision. The bud of the selection of the ball bearing lubrication is grease on the bearing fatigue life, temperature rise, friction, and vibration influence, good lubrication for the bearing work has played a very important positive role. According to bearing damage reason statistics, about 40% of the ball bearing damage reasons are related to bad lubrication. Good lubricating grease is to minimize the friction losses of bearing very effective measures, and the bearing rust and heat dissipation, cushion, seal are also play an important role.
