Single row spherical roller bearing: shielding pump bearing detector principle

The bearing of the motor ( The following are the rolling bearing) Is important support between stator and rotor parts, used to protect motor air gap and uniform load, and so on, the correct selection and application of the bearing is an important part of motor design. Insert ball bearing type code for u, however, where possible, the better solution is to use only the kind of grease, it should be compatible with sealing material. Spindle materials and heat treatment abroad carburizing spindle accounted for %, ceramic bearing and the advantages and disadvantages of the ceramic bearing: ceramic bearing atomic structure, inherent covalent bond, not of metal. Remove the bearing inspection: if bearing a serious fault and fever for some reason, the bearing should be removed, identify the cause of fever; If the bearing fever accompanied by noise, may be bearing cover and shaft wipe dry or lubricating grease. CPU fan is also known as the cooling fan is a kind of used to CPU cooling fan, provide for the use of the radiator and chassis, is to use their fast heat conduction from the CPU and blown into the air near the cooling effect. Rolling bearing compared with sliding bearing, however, each have advantages and disadvantages, each set of applicable occasions, therefore, they cannot fully replace each other, and to decide the direction of development, expand their areas. To the rear, code-named K, K taper hole spherical roller bearings, installed on the suitable set set, became the rear code-named K + H and K + H the bearing. Solution: clean, before bearing assembly, not card master roll diameter, roll under the dynamic is curved, straight cylindrical column bearing clearance can't satisfy the more amount of deflection. With quiet operation, low cost, can carry on the radial load and axial load, the advantages of low friction, low calorific value, high speed turn; The drawback is that unable to bear impact load or radial and axial load. Rolling bearing and sliding bearing first appearance on the structure, the difference between a rolling bearing is supported by the rotation of the roller axis of rotation, and the contact area is a point, the more rolling body, nine more contact point; Sliding bearing is to rely on a smooth surface to support the axis of rotation, so contact area is a plane. Because of bearing bearing cover and bearing assembly quality is not very good, commissioning, speed drop shaft vibration particularly big, wear and tear of the bolt screw thread; The overspeed test ( Speed up to r/min - Methyl amino acetonitrile) #, bearing the axial vibration of a sudden increase, cause bearing cover fixed bolt out, busbar loss; On the bearing and oil baffle ring after the take-off, and are unable to offer lower bearing lubricating oil, # a bearing. The manufacture craft is exquisite; From the point of appearance, bearing is just a 'big iron'; However, this 'big iron' contains the massive technical details. Such as structural strength, load capacity and transmission efficiency and so on.
