3 thoughts on “What are the issues of bearing? Pay attention to?”
Beulah
There is a saying in the bearing industry: “Three -point bearing, seven points”. You must know that the bearing is not installed properly, and the bearing with good quality is also white. The life of the bearings is closely related to manufacturing, assembly, and use. In particular, you need to pay attention to the following aspects in order to make the bearing in the best operating state, thereby extending the life of the bearing. Shang Mobi.com understands more bearing knowledge and master real -time bearing supply and demand information. The choice of tolerance of the shaft and bearing room to the tolerance The bearing should be flexible and unobstructed after pressing the axis. If it is not flexible, it means that the size of the axis is too large, and the tolerance should be reduced. If the shaft pressure is rotated after the axis is in the shaft, it may be a significant “rustling” feeling, which may be that the tolerance of the shaft may be too large or the roundness of the axis is not good. Therefore, the circularity must be controlled when controlling the tolerance of the shaft and bearing room to avoid excessive loss of the bearings. The assembly method of bearing Because the bearing is a high -precision product, it is easy to cause damage to the bearing channel if the assembly is improper, causing bearing damage. The bearing should have a dedicated mold when assembly. You cannot knock at will. When pressing into the axle, you can only stress in a small circle. When the lap is crushed, you can only stress in large circles. When assembling, it is required to use air or hydraulic pressure. The upper and lower molds should be outside the horizontal state during the pressure. The prevention of foreign objects The bearings are prone to residual foreign objects when assembly. In order to assemble for easy assembly, some manufacturers apply some oil or oil to lubricate effects in the bearing room during assembly, but it is often difficult for operators to control the amount. It is easy to enter the bearing along the shaft. Try not to apply oil or fat as much as possible, and ensure that there are no residues in the bearing room when applying it. The prevention of paint rust This rust is mainly issued in the sealing motor. The motor sounds good when assembly, but after some time in the warehouse, the abnormal noise of the motor becomes louder, and the bearing is removed and the bearings are removed. It was found that there was severe rust. Many manufacturers will think that it is a problem of bearing, but the actual reasons have nothing to do with the quality of the bearings. The problem is mainly due to the corrosive substances formed by the acidic substances volatilized by insulating paint in a certain humidity environment, which corrodes the bearing channel and causes the bearing to damage. The prevention method is also very simple, select the well -insulated paint, and assemble it after ventilation after drying.
I do n’t know from which angle you are It, I will say a few points. If you are a practical unit: The authenticity of the bearings is the overall requirements of the quality. It ’s because you do n’t take the high price yourself to buy bad quality. What is harmful to your own brand is that your own products. In addition, you must pay attention to the technical techniques of the bearing in the installation. Be sure to use heating bearing to use . If you are a installation unit, you should pay attention: The price of products requires high quality and low -cost products. Market inspection capabilities need to always grasp the market market of this product at the lowest price to buy your most suitable products. Remember to help prevent high -performance products using inferior equipment such as imported bearing. The use of the volume of the vehicle, the compliance of the magnification, hopes to understand . If you are an engineering researcher, you should pay attention: The in -depth understanding of product performance is all supplemented by everything else. Is I hope that my 7 -year -old man who has been engaged in this industry can help you. Thank you
