Therefore, under heavy load operation, the pitting is very easy to cause fatigue and wear and repair failure. For another example, if the coaxiality of the installation is not enough, it will cause the bearing to vibrate, cause the shaft to bend, increase the load, cause the bearing to fail, increase the number of times of bearing replacement, affect the dimensional tolerance of the bearing and the shaft or hole, and destroy its relationship. I hope that when you encounter such a failure problem, you must find the correct cause and use it according to the specific situation. The negative impact on the equipment is very large. This repair method is also an ideal repair plan.
It aggravates the wear and tear of the matching parts, and even charges for serious damages to the equipment and reduces the accuracy of the machine; Its advantage is that it can be repaired online, but its disadvantages are very obvious.. The reason why the bearing runs on the outer ring: The matching of bearings and shafts (holes) requires very strict requirements on shafts, holes, bearing machining accuracy,non-standard bearings factory fit tolerances, installation and assembly accuracy, materials, and use and maintenance. Its disadvantages are that the thermal stress causes great damage to the material, and it is easy to break the shaft during operation, which can cause shutdown or production stop accidents. Use structural adhesive XHI1-13 or AR-5 wear-resistant adhesive to mix evenly, and evenly spread it on the inner diameter of the hot-air-dried bearing after processing, the thickness of the glue is 1.
What is a bearing running jacket? The outer ring of the bearing can also be called the outer ring of the bearing. Based on the understanding of bearing knowledge, the following detailed answers are provided. The radial runout does not exceed 7 and the cylindricity of the bearing chamber does not exceed 7. The end cover can be heated, and the steel ring can also be cold-shrinked. Jam the bearing housing. This kind of treatment is to add pads on one side of the bearing, which will increase the axial pressure of the original structure bearing, which will easily lead to increased noise and vibration, and accelerate the damage of the bearing. Replace the end cap with the original manufacturer.
What is a bearing inner sleeve? The bearing inner sleeve can also be called the bearing inner ring, which usually means that there is a gap between the inner circle of the bearing and the shaft, which causes the phenomenon of asynchronous rotation with the shaft. These have industry standards. Summary: The above is an introduction to the problem of bearing running laps, and a detailed answer is given to the common causes and solutions of the inner and outer running laps. The brush plating process of the brush plating process is limited by the amount of wear.2mm. Different types of bearings should be made of suitable bearing steel, with high strength and rigidity, good wear resistance, and low friction coefficient of the bearing alloy, so as to ensure the normal use of the bearing and reduce the possibility of running circles.
The bearing and end cover are axially cushioned with wave spring washers to adjust the axial gap to reduce bearing noise and vibration, as shown in the figure. Used for short-term emergency repairs. If this happens, the operation should be stopped as soon as possible according to the actual situation and maintenance should be arranged.6～6×3.5mm. When the amount of wear is greater than 0.1. Different specifications, precisions, stress conditions, and use environments have different requirements for fitting tolerances. The locking parts of the bearing, such as the lock nut, clamp ring, end cover, etc. At the same time, pay attention to control the coaxiality of the bearing chamber and the stop. The hazards of bearing running circles: Note that the plane flameproof clearance between the inner cover and the end cover should be less than or equal to 0.
