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.

We all know that there are many types of raw materials for related bearings, and different industries have different types of applications. The commonly used raw materials for bearings include three categories: metal composite materials, porous structured metal composite materials, and non-metallic materials.

The noise of bearings not only affects the quality of use, but also brings a lot of trouble to mechanical equipment. In general, there will be some noise during the use of bearings, and the invasion of foreign substances can directly cause certain noises during the operation of bearings, or improper lubrication, inadequate installation, etc., which can cause various noises from the bearings. What methods can make the use of bearings less noisy?

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.

Assembly of sliding bearings: Sliding bearings are a type of bearing with sliding friction properties, characterized by smooth operation, reliability, low noise, and the ability to withstand heavy loads and large impact loads. They can be divided into integral, split, and tile types according to different structural forms. (1) The assembly of integral sliding bearings, commonly known as shaft sleeves, is also the simplest form of sliding bearings. It is mainly assembled by pressing and hammering, and in special cases, hot fitting is used. Most shaft sleeves are made of copper or cast iron, and assembly should be careful. Wooden hammers or hammers can be used to hit wooden blocks during assembly. When the interference size tolerance is large, a press is used to press in. Regardless of whether it is knocked in or pressed in, it is necessary to prevent tilting. After assembly, the oil tank and oil hole should be in the required position.

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.

Cause analysis:

It can be generated by the vibration and collision between the retainer and the rolling element, regardless of the type of lubricating grease, and is more likely to occur when subjected to torque, load, or large radial clearance.

Cage, also known as bearing cage, refers to a bearing component that partially wraps all or part of the rolling element and moves with it, used to isolate the rolling element. It usually guides the rolling element and keeps it inside the bearing.

Rolling bearings use various mechanical equipment, and the increasingly stringent market requirements for imported bearings require equipment and other properties, resulting in increasingly diverse performance. To select the most suitable bearing from a large number of structures, sizes, and requires different angles. When choosing imported bearings, it is generally believed that the difficulty arrangement of installation and removal, the size of imported bearings, and the market for bearings, as well as the space allowed, generally determine the structure of imported bearings. Comparative research on the design lifespan of various machinery and the limitations of various durable imported bearings, while determining the bearing size.

The world's smallest steel ball bearing is located in Tokyo, Japan. Meibei Co., Ltd. announced that its steel balls have been awarded the Guinness World Record for the smallest commercial steel ball bearing. Representatives from Guinness World Records Co., Ltd. have certified that the outer diameter of its steel balls is only 1.4978 millimeters. Maybella has been trying to prove its ability to produce the smallest mass-produced bearings.

Using a sound meter to check the size and sound quality of the rolling sound of the running bearings, even if there is slight peeling or other damage to the bearings, abnormal and irregular sounds can be distinguished by using a sound meter.

Using auditory perception to identify irregular movements is a common method. For example, using an electronic stethoscope to detect abnormal noise in a certain part is often a method used by experienced operators. If the bearings are in good continuous operation, they will emit a low whining sound. If sharp hissing, squeaking, and other irregular sounds are emitted, it often indicates that the bearing is in poor continuous rotation condition.

Bearings are an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. With the increasing demand for bearings, problems such as premature damage and short lifespan of bearings are troubling every mechanical enthusiast.

The equipment manufacturing industry is the foundation of a country's industrial development and a core component of the manufacturing industry, responsible for providing production technology and equipment for the national economy and defense construction. Establishing a strong equipment manufacturing industry and achieving the localization of high-end equipment is the fundamental guarantee for improving China's comprehensive national strength and achieving modern industrialization.

1. Requirements for monitoring rolling bearings using magnetic plugs

(1) Magnetic plugs are only suitable for monitoring critical main bearings lubricated with oil and returned through dedicated pipelines.

(2) The magnetic plug should be installed as close as possible to the main bearing being monitored, on the main channel for oil return, without the obstruction of a filter screen, oil pump, or other hydraulic components in the middle.

(3) In order to improve monitoring efficiency, a rotary oil storage tank with return oil inlet and outlet can be made. The oil reservoir should be designed in an inverted conical table shape, and the magnetic plug should be installed at the bottom of the oil reservoir. The oil inlet of the oil reservoir should be tilted at a certain angle to allow lubricating oil to enter from the tangential direction. This is beneficial for the separation of abrasive particles from the lubricating oil that circulates, settling at the bottom, entering the magne
