It is said that damage when installing motor deep groove ball bearings accounts for 20% of bearing damage. How can we reduce damage when installing bearings?The following is a detailed introduction to the specific requirements for the site when installing bearings. The site must be kept dry and clean, and iron filings, sand, dust, moisture, etc. must be prevented from entering the bearings.Commonly used installation tools for motor deep groove bearings include hand hammers, copper rods, sleeves, special backing plates, screw clamps, presses, etc. The tools include vernier calipers, micrometers, dial indicators, etc., but they need to be selected according to different bearing models. Tool of.After choosing and using the correct tools, you can install the bearing. During installation, pay attention to whether there are bruises, rust layers, abrasive chips, sand, dust and mud. If there are any, it will cause installation difficulties. You must keep them imported. Bearing mounting surface

Wind turbines are generally divided into doubly fed, direct drive, and semi direct drive types. Various types of motor bearings are widely used in wind turbines, and the traditional doubly fed wind turbine has the largest number and most complete types of bearings. A wind turbine can use up to 32 sets of bearings. So choosing the right bearings is very important to ensure the safe and stable operation of wind turbines. Wind turbines are installed in areas with high wind and sand or humidity in the wild. The working conditions of wind turbine bearings are very harsh, and they need to withstand a wide range of temperature, humidity, and load changes. Especially the yaw and pitch bearings need to withstand significant axial forces and overturning moments, while the gearbox bearings need to withstand significant impact loads during start-up and braking. At the same time, it is also required that the gearbox bearings of the fan have low friction torque and high operation during low-speed st

When installing the inner ring of a bearing on a deep groove ball bearing, the position of the bearing is usually fixed on one side by the shaft shoulder, while the other side is fixed with nuts, stop washers, or spring retaining rings, etc. The dimensions of the contact part between the shoulder and axial fixed parts and the inner ring of the bearing can be determined according to the installation dimensions of various types of bearings listed in the bearing size table.

Deep groove ball bearings are suitable for high-speed or even extremely high speed operation, and are very durable without frequent maintenance. This type of bearing has a low coefficient of friction, high limit speed, diverse size range and forms, and is widely used in industries such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery. It is the most widely used type of bearing in the mechanical industry. It mainly bears radial loads and can also withstand a certain amount of axial loads.

The detailed configuration of motor bearings not only involves the motor bearings themselves, but also other related accessories such as shafts and bearing seats, which are all key components of the motor bearing system. In addition, lubricants and hydraulic seals are also very important components. To fully utilize the characteristics required for a bearing in all aspects, it is necessary to apply suitable lubricants and a reasonable sealing system software to prevent air pollutants from entering the bearing. After many years of certification, cleanliness poses a significant threat to the service life of bearings, which is the key reason why standard bearing manufacturers extended their business scope to lubrication and sealing products many years ago.

Deep groove ball bearings are the most common rolling bearings. Its structural features are relatively simple, convenient to use, durable, and it plays many functions, with the most common technological applications in various industries. Next, Lutai Bearing Co., Ltd. will explain in detail its technical application in motors. Deep groove ball bearings are the most frequently used bearing type in motors. Its key function is to bear axial loads, but when expanding the axial clearance of rolling bearings, it has the necessary characteristics of angular contact ball bearings and can bear radial and radial synergistic loads. When the rotational speed is relatively high and it is not suitable to use thrust ball bearings, they can also be used to bear pure radial loads.

Bearings are components used to support and also to support rotating parts on the shaft. The types of bearings are classified according to their friction properties: sliding bearings and rolling bearings; Classified by the direction of load bearing: radial bearings, thrust bearings, radial thrust bearings, etc. Our three light wire cutting machine tool requires a lot of assembly of bearings, and understanding this knowledge is very helpful for the maintenance and assembly of the machine tool.
