The difference between the high speed bearings and plain bearings

General high speed bearing is the speed reached 60 meters per second bearing. Bearing high-speed, medium-speed and low-speed but not with the speed given at a line speed given. Quick to turn tens of thousands of small bearings is not high-speed bearings, large bearings even a few hundred turn high-speed bearings. Sliding bearings, hydrostatic bearings, hydrodynamic bearings, aerostatic bearing, the gas dynamic pressure bearing are suitable for high-speed rotation. Adaptation and general rolling bearing rotational velocity in low,If you use a high-speed rotation of rolling bearings requires special requirements. Above the national standard bearings are easily found in the bearing, it is reasonable to choose their models based on the use of the load and other factors.

Ferris wheel to take "sub-assembly method with" Install

Ferris wheel to take "sub-assembly method with" Install. Firstly the spindle and the ferris wheel bearing installation, which is the dot whole Ferris wheel; followed by the installation of the wheel and cockpit, wheel outside the racking several transparent cockpit, which can concept for hundreds of people; and finally electric drive mounting device, which is located in the Ferris wheel and bridge binding place, after opening the Ferris wheel can be controlled uniform rotation, revolution needs about 30 minutes to reach the highest point, with sweeping views of the surrounding, you can see within a radius of 40 km views. Ferris wheel means no gear wheel bearings four point contact ball slewing bearing, a separate type of bearings, it can be said that a two-way bearings can withstand axial load angular contact ball bearings.

Wheel bearings applied ferris wheel bearing

turntable bearing can withstand a large axial load, radial load and overturning moment, such as integrated load, set bearing, large bearing rotation, transmission, fixed and other functions in a special structure. Under normal circumstances, transfer All with their own plate bearing mounting holes, lubricants and seals, to meet the different needs of a variety of different types of work working conditions hosts; on the other hand, wheel bearing itself has a compact, convenient rotation guide, installation Simple and easy maintenance, etc., are widely used in material handling equipment (ferris wheel bearing), mining machines, construction machinery, port machinery, wind energy, medical equipment, radar and missile launchers and other large rotary device.

ship loader bearing

ship loader bearing is used for bulk loading dock used for large bulk handling mechanical bearings. Usually by the boom belt loading machine, the transition belt conveyor, telescopic chute, tail car, running gear, mast, tower, tilt device, slewing drives and other components, a large bulk shipment port equipment, energy, electric power, metallurgy, ports and other industries, especially some large bulk distribution center speed, stability, collection efficiency, rolling development, plays an important role. Installed generally continuous loading operation. Therefore, there must be a complete set of equipment to provide a continuous flow of material loading machine can make continuous shipment. Such as feed grain terminal barn, yard Coal Terminal in bucket wheel reclaimer continuous feeding feeder like.

Acoustic emission technology

Acoustic emission (ae) technology as one of the early detection of material injury powerful tool has been widely used in petroleum, petrochemical, power, aviation, aerospace, metallurgy, railway, transport, coal, construction, machinery manufacturing and other processing, at low speed Overload device diagnostics field acoustic emission-line monitoring for port Crane (mobile crane bearing), providing more accurate information to the low-speed rolling bearing fault diagnosis, discussed the application of acoustic emission sensors to monitor the speed (10 ~ 1850) r / min angular contact bearing, found at low speed acoustic emission sensors in each pair of bearing balls bearing concentrated loads caused by small strain responsive, further evidence of the effectiveness of the acoustic emission technique.

Roller coaster

Roller coaster on our common observation wheel will need at least two large spindle bearing, this bearing applications we called ferris wheel bearing, each side needs to custom design a spherical roller bearings, which sealed spherical roller bearings almost unprecedented weight and size. Each bearing the weight of about 8800 kg, it is designed to be an outer diameter of 2300 mm, an inner diameter of 1600 mm, and 630 mm in width, while the use of advanced lubrication, sealing and online condition monitoring system and lead monitoring bearings.

What materials are used in wheel bearings

Rolling bearing steel is mainly used in the manufacture of rolling elements and rings. Since the bearing should have a long life, high-precision, low heat, high speed, high rigidity, low noise, high wear resistance and other characteristics, thus requiring bearing steel should have: high hardness, uniform hardness, high elastic limit, high contact fatigue strength, toughness necessary, certain hardenability in atmospheric corrosion lubricant. To achieve the above performance requirements, bearing steel chemical composition uniformity, non-metallic inclusion content and type, carbide size and distribution of decarbonization and other demanding. Bearing steel development to quality, performance and overall direction of many varieties. To meet the high-temperature, high-speed, high load, corrosion, anti-radiation requirements, the need to develop a series of new bearing steel called special bearing with special properties. Along with economic development and industrial technological progress, expand the scope of application of the bearing; and the development of international trade, but also to promote the development and application of bearing steel to international standards and new technologies, new processes and new equipment, high efficiency, high quality, cost Low of supporting technology and process equipment came into being.
