Introduction
Joint bearing is an important component in machinery and an indispensable part of machinery and equipment. A joint bearing is a kind of bearing that converts the axis rotation or tilting movement between the two connecting parts. Joint bearings are widely used in automobiles, helicopters, ships, agricultural machinery and other machinery. Compared with the general rolling bearing, the joint bearing has its own characteristics, and its application range is also very wide. The following describes the characteristics and application of joint bearing.
Characteristics of Joint Bearings
1. Joint bearing can bear large load, joint bearing has good bearing capacity, it can bear great load, meet the requirements of high speed rotation and cope with the motion of swing shaft components.
2. Joint bearing has reliable sealing performance, using reliable dust-proof, rain-proof and corrosion-proof sealing performance to prevent lubricating oil from being added to the bearing, which can prevent dust, water and other liquid impurities from entering into the bearing and reduce the bearing failure rate.
3. Joint bearing has good radial runout accuracy, radial runout accuracy direct affect the normal operation of the bearing, joint bearing can effectively ensure the radial runout accuracy and reduce the vibration of bearing.
4. Joint bearing has strong adaptability. The bearing is designed with appropriate preload and can make the bearing move reliably, which can ensure the secure operation of the bearing.
5. Joint bearing has simple structure. Its inner and outer raceways have good self-aligning ability and its friction coefficient is small, which simplifies the components and reduces the problems caused by assembly.
Application of Joint Bearings
1. Automotive. Joint bearings are widely used in automotive industry, such as drive axle, transmission axle, steering axle, suspension and so on.
2. Aerospace. Joint bearings are widely used in the landing gear of aircraft, the pitch adjusting shaft and the gyro.
3. Shipbuilding. Joint bearings are widely used in marine main engine, marine auxiliary machine and many other parts of ship.
4. Engineering Machinery. Joint bearings are widely used in engineering machinery such as cranes, excavators, loaders, rollers, etc.
5. Agricultural Machinery. Joint bearings are widely used in tractors, agricultural machinery and other fields.
Conclusion
The joint bearing has its own characteristics, can bear greater load, has good dust-proof, rain-proof and corrosion-proof sealing performance, good radial runout accuracy, strong adaptability and simple structure, and its application range is very wide. It is widely used in automotive, aerospace, shipbuilding, engineering machinery and agricultural machinery. Joint bearing is an important component of machinery and equipment, and plays an important role in normal operation of machinery.
