Imported bearing installation directly affects its performance and service life

Bearings are one of the important components on construction machinery. Poor installation will affect their use and even cause failure of construction machinery.

If foreign matter such as iron filings, burrs, dust, etc. enters the imported bearings, the imported bearings will generate noise and vibration during operation, and may even damage the raceways and the moving bodies. Therefore, before installing the bearing, it is necessary to ensure the cleaning of the mounting surface and the installation environment.

In order to make the imported bearing perform well, first of all, it is necessary to select a lubrication method suitable for the premise and purpose of use. In addition, increased vibration and friction can greatly increase energy consumption and risk of premature failure. The method of bearing lubrication is divided into grease lubrication and oil lubrication. The thickener is also related to the lubrication function, and the water resistance of the thickener determines the water resistance of the grease. Lubrication has a very important influence on the operation and life of the bearing. Fully sealed imported bearings do not need to be cleaned and refueled.

The surface of the imported bearing is coated with anti-rust oil. It must be carefully cleaned with clean gasoline or kerosene, and then cleaned with high-quality or high-speed high-temperature grease to be installed. The function of the grease is mainly determined by the base oil. In principle, the different greases of the brand cannot be mixed, and even the grease of the same thickener may have a bad influence on each other due to the different additives. Grease is made from base oils, thickeners and additives. Generally, low viscosity base oils are used for low temperature and high speed; high viscosity is used for high temperature and high load.

After the imported bearings have been installed, if the alignment is not carefully performed, alignment may result in additional loads, friction and vibration of the bearings. These may accelerate fatigue and reduce bearing life and may damage the life of other machine parts. The most important component of the bearing piston pump for hydraulic pump is the bearing. Reducing the negative pressure in the imported bearing is the basic requirement to prevent water from entering. The load calculation of the angular contact bearing. The oil supply maintenance of the locomotive bearing is very important.

In operation, imported bearings require accurate relubrication to perfect its performance. These regular inspections will detect latent problems early and will prevent unexpected machine suspensions, enabling production plans, improved plant productivity and efficiency. If only lubrication is considered, the lubricity of oil lubrication prevails. However, grease lubrication has the advantage of simplifying the structure near the imported bearings.

Several methods for rust prevention of imported bearings

1) Surface cleaning: Cleaning must be based on the nature of the surface of the rust-preventing material and the conditions at the time. Commonly used are solvent cleaning, chemical cleaning and mechanical cleaning.

2) Dry and clean the surface, dry it with filtered dry compressed air, or dry it with a dryer at 120~170 °C, or dry it with clean gauze.

Method for applying rust preventive oil

1) Immersion method: Some small items are immersed in anti-rust grease, so that the surface is adhered with a layer of anti-rust grease. The oil film thickness can be achieved by controlling the temperature or viscosity of the rust preventive grease.

2) Brushing method is used for outdoor construction equipment or special shape products that are not suitable for soaking or spraying. When painting, it is necessary to pay attention not to accumulate, but also to prevent leakage coating.

3) Spray method Some large-scale rust-proof materials cannot be oiled by immersion method. Generally, the filtered compressed air with a pressure of about 0.7Mpa is sprayed in an air-cleaning place. The spray method is suitable for solvent-diluted anti-rust oil or thin-layer anti-rust oil, but it must adopt perfect fire and labor protection measures.

What are the main factors affecting metal corrosion?

Metal corrosion is caused by a variety of internal and external factors, which are summarized as follows:

1 the chemical composition and structure of the metal material itself;

2 metal surface finish (oxygen concentration difference battery corrosion);

3 the composition of the solution in contact with the metal surface and the pH value;

4 ambient temperature and humidity;

5 Various environmental media in contact with the metal surface.

Why does hand sweat cause metal corrosion?

Human sweat is a colorless, transparent or light yellow liquid with a salty, slightly acidic pH with a pH of 5-6. In addition to sodium, potassium, calcium and magnesium salts, it also contains a small amount of organic acids such as urea, lactic acid and citric acid. When the sweat comes into contact with the metal, a sweat film is formed on the metal surface, and the sweat film causes an electrochemical action on the metal to corrode the metal. People sweating is inevitable. To prevent rust from sweating, production personnel should wear gloves, finger cots, or take special parts with tools. Do not touch the product with your hands.
