How to choose the type, type and size of IKO bearings is varied. In order for the mechanical device to perform as expected, it is essential to select the most suitable IKO bearing. In order to select IKO bearings, it is necessary to analyze a number of factors, and to study and evaluate the procedures for selecting IKO bearings from various angles. There are no special specifications, but the general order is as follows:
1. Master the use conditions of mechanical devices and IKO bearings, etc. 2. Identify the requirements for IKO bearings. 3. Select the type of IKO bearing. 4. Select the IKO bearing configuration. 5. Select IKO bearing size. 6. Select IKO bearing specifications. 7. Selection method of IKO bearing selection IKO bearing use conditions and environmental conditions correctly grasp the IKO bearings in the mechanical parts of the use of parts and conditions of use and environmental conditions is the prerequisite for the selection of suitable IKO bearings. For this, you need to obtain the following data and information:
1. Function and structure of mechanical device 2. Location of IKO bearing 3. IKO bearing load (size, direction)
4, rotation speed 5, vibration, impact 6, IKO bearing temperature (ambient temperature, temperature rise)
7, the surrounding atmosphere (corrosive, clean, lubricative)
The correct use of IKO bearings is a reliable guarantee for reducing IKO bearing failures and extending IKO bearing life, including proper installation and proper lubrication. The following describes the requirements for the use of IKO bearings.
1. Disassembly and assembly of IKO bearings IKO bearings should be cleaned before installation. When installing, use a special tool to press the auxiliary bearing straight and evenly. Do not hit with a hammer, especially for directly hitting the IKO bearing. When the IKO bearing race and the seat hole are loose, the seat hole should be repaired or the IKO bearing should be replaced. Do not use the method of pitting or padding on the IKO bearing mating surface. When removing the IKO bearing, use a suitable puller to pull the IKO bearing out. Do not hit the IKO bearing with a chisel or a hammer.
2, IKO bearing lubrication IKO bearings commonly used lubricants are lubricants and grease. When the peripheral speed of the shaft is less than 4-5m/s, or the part of the car that cannot be lubricated with lubricating oil, it is lubricated with grease. The advantage of grease lubrication is that the sealing structure is simple, the grease is not easy to be lost, and the temperature is not affected much. The grease can be used for a long time.
Lubricating oil has the advantages of low frictional resistance and heat dissipation, and is mainly used for IKO bearings with high speed and high working temperature. The grade of the lubricating oil should be selected according to the requirements of the automobile manual, and the vehicle maintenance cycle should be replaced in time. After the old oil is discharged, the mechanism should be cleaned and then new oil should be added. The fuel should be added to the specified marking line or flush with the filling port. (Depending on the specific structure and requirements of the car), it is not allowed to add more.
There are two problems to be aware of when using grease. First, select the appropriate grade of grease according to the requirements of the car manual. For example, NPO greases are not suitable for automotive water pump IKO bearings because of their poor water resistance. Second, the amount of grease added to the IKO bearing should be appropriate. Generally, only 1/2-l/3 of the IKO bearing cavity is filled. Excessive use is not only useless, but also increases the running resistance of the IKO bearing to make it heat up. Special attention should be paid to the IKO bearing of the automobile wheel hub. It is necessary to promote “empty hub lubricationâ€, that is, only apply an appropriate amount of grease on the IKO bearing. Otherwise, it will not only waste and dissipate heat, but also cause the grease to overflow. May affect braking performance.
