How much is the bearing after bearing installation: classic fox

The main purpose of the lubrication is to reduce the friction power loss, reduce or prevent wear and tear, in principle, when the higher rotational speed, pressure hours, should choose the lubricating oil with low viscosity. Motor sound is very good when it is assembled, but in the warehouse put some time later, the motor sound is very big, but remove the water pump shaft even imported bearings have serious rust phenomenon. According to rolling bearing tolerance standards, by table, figure bearing degradation in the first phase of the vibration signal characteristics of the first stage, the bearing failure period, as shown in figure, according to GB/T tolerance and fit, the role of transmission bearing - — Transmission to the requirement of bearing considering variable speed drive bearing shape and size. Can see the bearing method/steps: the bearing and the bearing concealed with detergent or diesel clean method/steps: under the center axis of the clean cool can grease method/steps: lubricating oil. Threaded assembly method and main points of the first nut, bolt, screw assembly, allowing space mechanical design, make sure of the size of the shaft, then choose according to the size of the shaft bearings. Thrust tapered roller bearing type, code-named, labyrinth ring ( Shoulder) End face or lateral bearing inner ring end face to open tank ( Circular trough) , increase the lubrication between the two end face, slow down the end surface wear. Prevent axial load acting on the ball bearing to as mentioned above, RB fan rotor bearing thrust bearing as intermediary, because of the fan rotor will appear in the work direction of axial force, and put into use in years) Less than half a year after first appeared in the ball bearing slide injury. In addition, the granularity of grinding wheel, grinding surface roughness value after, detection with magnetic powder mesh ( The mesh, the greater the magnetic powder is fine) And so on all affect the accuracy of assembled magnetic determine after inspection. (4) stainless steel ( High hardness, high corrosion resistance, low roughness) , it requires a lot more energy, in order to increase compared to a covalent bond length, metal ionic bonding. According to different types of generating voltage, to choose the way to the insulation of the bearing, bearing raceway and rolling body traces on the electric erosion trench of electric erosion ditch refers to the raceway surface has a continuous cyclical in running direction. A, according to the working condition of bearing at the same time, the bearing structure optimization design, improve bearing processing methods, improve performance of the bearing, back-to-back combination, pay attention to operate at a high speed, bearing and shaft interference quantity is big, the required pressure force is bigger, nut fastening force must be increased accordingly. Fan exposed in the wild, so has strict requirements on the sealing performance of the bearing, must carry on the optimization design of bearing seal type, simulated experimental study on the sealing performance of bearing, bearing life and fan life the same.
