INA bearing

wallpapers News 2021-06-17
INA bearing is a kind of bearing which adopts dilute grease and oil mist lubrication method, and is an important part of modern machinery and equipment. The main function is to support the mechanical rotating body, reduce the coefficient of friction during its movement, and ensure its rotation accuracy. It is mainly divided into cylindrical roller bearings and self-aligning ball bearings.
Application of INA bearings
The industries involved in INA bearings include: agricultural machinery industry, construction industry, hydraulic and wind engineering industry, construction machinery industry, machine tool and manufacturing machinery industry, material handling and packaging industry, port engineering industry, power tool industry, gearbox industry, semiconductor Industry, pump and fan industry, industrial robot and automation industry, rubber, plastic and chemical industry, textile industry, tractor industry, woodworking machinery industry, etc. In these industries, INA bearings have been widely used.
Installation of INA bearings
1. Before installing the bearing on the shaft, you must first unplug the fixing pin of the bearing housing, and at the same time polish the surface of the journal smoothly, and apply oil to the journal to prevent rust and lubricate (allow the bearing to rotate slightly on the shaft).
2. Apply lubricating oil on the mating surface of the bearing seat and the bearing, and install the INA bearing in the bearing seat. Then put the assembled bearing on the shaft together with the bearing seat. Push to the desired location for installation.
3. Do not tighten the bolts that fix the bearing seat, but allow the bearing housing to rotate in the bearing seat. Also install the bearing and seat on the other end of the same shaft, rotate the shaft a few times, and let the INA bearing automatically correct its position. Then tighten the bearing seat bolts.
4. Install eccentric sleeve. Put the eccentric sleeve on the eccentric step of the bearing inner sleeve first, and tighten it by hand in the direction of rotation of the shaft. Then insert the small iron rod into or against the counterbore on the eccentric sleeve. Knock the small iron rod along the axis of rotation with a hand hammer. Install the eccentric sleeve firmly, and finally tighten the hexagon socket screws on the eccentric sleeve.
Lubrication method of INA bearings
General working INA bearings adopt thin grease and oil mist lubrication methods. These lubrication methods have their own characteristics. However, to meet the working requirements of modern high-speed, high-load work roll bearings, oil and vapor lubrication can be considered more appropriate.
Lubrication has an important impact on the fatigue life and friction, wear, temperature, vibration, etc. of INA bearings. The most outstanding feature of ceramic bearings is that without normal lubrication, the bearing cannot work. Analysis of the causes of bearing damage shows that about 40% of bearing damage is related to poor lubrication. Therefore, good lubrication of INA bearings is an effective measure to reduce bearing friction and wear. In addition, the lubrication of the bearing is also affected by heat dissipation, rust prevention, sealing, and impact mitigation.
Under high-speed and high-temperature conditions, oil lubrication can be used when the INA bearing combination position and clearance adjustment scheme is not suitable for grease lubrication. Through the circulation of lubricating oil, a lot of heat can be taken away. Viscosity is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of the oil film formed between the friction surfaces. The viscosity of lubricating oil at the working temperature of the bearing is generally 12-15cst. The higher the speed, the lower the viscosity, the heavier the load, the higher the viscosity. Commonly used lubricants include mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, and cylinder oil.
The internal clearance of the INA bearing increases due to wear during operation. The increase in the bearing clearance will reduce the load bearing area inside the bearing and increase the running noise and other unfavorable factors. Therefore, when considering the re-use standard of bearing clearance, the bearing with increased clearance should be used first according to the working conditions of the main engine.
Lean rolling bearing technology, advanced production plants, and superior quality standards make INA bearings famous and enduring in the world. It has been fully proven in millions of practical applications. INA bearing products are reliable mechanical parts with both cost and benefit.
