High temperature bearing installation work of technical application skills

High temperature bearing installation work of technical application skills bearing assembly is provided with high temperature washing and drying work ( Work) The nature of the. Especially the subminiature and ultra high temperature ball bearing if the component that greatly affect performance of high temperature bearing dust intrusion, and therefore should be stopped in a clean room, dimensional accuracy and the necessary high temperature bearing test field device ( Accuracy) And shape accuracy of luminosity, confirmation of these measures is within the allowed tolerance. In addition to the above items, other should pay attention to the following matters: ( 1) And cooperate with the surface of the shell ( A) The axis of the burrs, bruised, projecting part, iron mold, and the oil removal, in addition, the face a short period of time to be smooth, they painted in oil such as Spindle oil will easier to insert the data. As shown in figure 9 - the operation and programming 2. High temperature effect with high temperature bearing device shaft bearings, such as a hammer to tap directly lead to bearing high temperature as well as between the end face with high temperature may cause damage to the bearing, and therefore must exert an equal society on the ring circumferential stress come into the ring. And, as one side of the enterprise's ring ( For example, For example, like) Outer ring) A certain pressure, through to the other side of the roller ring ( Such as inner ring) Pressure were raceway surface indentation will attack or scars, shall be supported to prevent. ( 2) Assembly with tools use assembly tools, such as stamping press or choose the right size and high temperature bearing contact position ( Bearing) ； Tools must be removed dirt ( The soil) , edge, chip, etc. The application of high temperature bearing cleaning environment of high temperature bearing is very important. Circular surface and rough surface precision of the rolling element is about 1/10 mu m, so the lubrication of ball if the pollution of appearance, the impact is very serious. In order to obtain high temperature bearing low friction torque, high rigidity and good rotating accuracy, using small diameter steel ball. The use of hollow shaft to ensure the lightweight and wiring space. Thin wall high temperature bearing finished to a very thin cross section of high temperature bearing, also finished product miniaturization, lightweight. The diversity of products to expand the scope of its use. ( 3) High temperature bearing bearing temperature must be just opened in front of the protection device. Again, the high temperature lead to bearing is very clean in the process of the high consumption level in the fine chemical products, please don't make any other processing, such as cleaning. ( 4) Small amount of interference of high temperature bearing ( 轴承) The high temperature influence of the interference amount smaller bearing ( 轴承) Assembly, clear can distinguish roughly for pressure into the shaft, shell ( A) And equal pressure into the shaft and the shell ( A) , assembly method is the application of sleeve under pressure of the ring width, the high temperature by the sleeve to causes the bearing pressure and pressure force ( 角色) In high temperature, and the center of the bearing ( When high temperature to bearing device shaft, applying pressure shall be within a circle; High temperature through bearing to device in the shell ( When applying pressure to outer ring at the university) To make full circle average pressure into the ring; But if the bearing temperature protection, control device requires a lot of research is use hand press or hydraulic press. The separation bearing type high temperature equipment shall be at the same time can load the shaft and the shell ( A) , with the shim will equal inside and outside the circle pressure into the shaft and the shell ( A) 。 A: a common failure mode and countermeasures under a high temperature bearing: none
