Bearing seal ring: bearing model is not the same as the same size

Method: check the suction pipe and the bottom valve, plug leakage gas source; Clean up the water inlet of silt or plugs; Bottom valve must be greater than the water depth of the inlet pipe diameter. The preparing work before assembly, shaft neck after coated with red lead, mount bearing shell, turn two laps; Then take out the bearing shell, can be seen that the highlights on the bearing shell has red lead yan. To do a good job of preparation, that is, the removal of equipment, tooling processing, related tools and the preparation of personnel to ensure enough space construction and safe working environment; 。 In the system of wind power equipment maintenance is also important, bearing internal structure parameters and the structure of cage, the bearing has good performance and life. Analysis of the problems existing in the vibrating screen remain the state of vibration in the process of production, so the sieve sieve body on the installation components are prone to loose, such as vibrator housings, vibrator shield, sieve plate, etc. , the vibrator as source of vibrating screen, its fastening bolt looseness are more likely to happen. Shoulder fillet is too big or too small can cause what problem actually, made it clear in machine design teaching material: the radius is too big, round hole part of the bearing chamfer may be small, so the rounded and chamfering is interference, the bearing and the shaft shoulder depend on is not tight, use in the easy to cause vibration; Radius is too small, easy to produce stress concentration, shaft shoulder will affect the strength of the shaft. Raceway tilt spalling flake is tilted on the surface of the bearing work band, bearing is inclined in a state of work, when the tilt Angle to achieve or exceed the critical state to early formation of abnormal wear and spalling sharply. Huey long mechanical small make up remind everybody to use bearing should pay attention to the time, the bearings of knowledge: bearing clearance, however, clearance is too large will change the dynamic characteristics of bearings, rotor caused by unstable operation. Times the length of ~ mm, now to analyze the related factors influencing service life of bearing some conditions, as well as the bearing lubrication effect on the bearing life and use it. Adjusting nut should be used according to satisfy the spindle accuracy requirement, and the principle of bearing temperature rise is not high, you should check the spindle axis neck and taper error or replace new bearing. Selection criteria and considerations for high temperature and high temperature grease grease commonly known as 'heat butter', selects the inappropriate heat butter there will be a loss, become sticky, carbon, coking, accelerated wear and even lead to corrosion, abnormal equipment, interrupt production, production accident and other serious consequences. If in the process of running FAG bearing inner ring temperature higher than axis, cooperate will become loose and exceed allowable values, so it is necessary to choose tighter fit, for example with alternative k m.
