I believe you are no stranger to roller bearings. In fact, roller bearings mainly rely on the rolling contact between parts to support rotating parts. Then different roller bearings bear different axial and radial forces, so the use environment has a great impact on roller bearings. Let Zhejiang roller bearing factory talk about the impact of the environment on roller bearings. Selecting the size and accuracy of the gauge according to the service position, service conditions and environmental conditions, and matching appropriate bearings are the premise to ensure the service life and reliability of angular contact ball bearings. Angular contact ball bearing is suitable for bearing the combined radial and axial load dominated by radial load. It is usually used in pairs with two sets of bearings. It is mainly used in the transmission parts of automobile, such as front and rear hubs, driving bevel gears, differential, reducer and so on. Under the condition of correct installation and good lubrication, it is allowed to be 0.3-0.5 times of the bearing limit speed. Under normal conditions, it is appropriate to use 0.2 times of the limit speed. Tapered roller bearings generally do not allow the shaft to tilt relative to the housing hole. If there is an inclination, it shall not exceed 2 '.

Bearing is very important for mechanical equipment. If there is no bearing, it will directly affect the operation of the equipment. Have you ever heard of deep groove ball bearing? This is a common one. The processing procedures of deep groove ball bearings have been improved in quality, which can improve the beauty of bearings and reduce friction. The following is a brief series to share the processing steps of deep groove ball bearings:

The smooth processing of mechanical equipment is inseparable from the assistance of bearings. The failure of machinery during normal operation is likely to be caused by bearing failure. Therefore, it is very important to learn how to store, install and disassemble bearings. Today, I will tell you about the skills of installing and disassembling bearings.

1. Pay attention to the operation of one-way bearing during use. In case of noise, impact and sudden increase in power, stop the machine immediately for inspection, eliminate the fault, and dismantle it for inspection if necessary. 2. Under the general strip plane bearing inspection parts, the one-way bearing shall be lubricated once every 60 hours of operation. In tropical areas, areas with high humidity, much dust, large temperature changes and continuous operation, the lubrication frequency shall be increased. New grease must be added before and after the machine stops running for a long time. Slowly rotate the one-way bearing during grease filling to fill the grease evenly. 3. Check the plane bearing frequently. Check the plane bearing to see if the seal is in good condition. If the plane bearing is found damaged in the plane bearing inspection, it shall be replaced in time. If it is found to fall off, it shall be reset in time. The tooth surface shall be replaced with grease regularly according to the working environment. During use, the user shall refill with new grease according to different working conditions. 4. Prevent the unidirectional shaft from being directly exposed to the sun during use. It is forbidden to directly flush the one-way bearing with water to prevent water from entering the raceway, and strictly prevent hard objects from approaching or entering the gear plane bearing to check the meshing area. The four aspects that should be paid attention to in the daily maintenance of one-way bearings need to be paid great attention. Through the above introduction, I believe you should have some understanding of our maintenance precautions for using one-way bearings. In fact, no matter what equipment or parts are in use, you must remember to carry out maintenance, We need to remember that we must not use water to flush the bearing directly, so there will be a big problem in plane bearing inspection, which will lead to equipment shutdown and even more serious plane bearing inspection. Therefore, we must pay attention to finding regular personnel for maintenance during maintenance.

Bearing is not only widely used in various machinery, but also plays a very important role in automobile wheels. It is mainly to make it run normally. So how to judge the quality of bearing from its appearance? The following points should be paid attention to in the appearance inspection: (1) Various cracks, such as raw material cracks, forging cracks, heat treatment cracks and grinding cracks, will become the source of stress concentration and expand rapidly in the later operation of the bearing, resulting in bearing fracture, which has a great impact on the service life and work safety of the bearing.

There are bearings in many engines. As long as the bearings fail, they will stop running and the work can not be carried out. If you want to improve the reliability of the engine, you need to start with the bearings. Next, I will introduce in detail the five measures to improve the reliability of the engine bearings.

Bearing steel is the raw material of traditional bearings. According to the production materials, bearings can be divided into bearing steel bearings and stainless steel bearings, as well as some less used aluminum alloy bearings. Bearing steel has very strict chemical composition requirements, so the chemical properties of bearing steel bearings are very stable, and there will not be much difference in mass production. Today, Xiaobian will introduce to you what is bearing steel bearing and its performance!
