Rod end joint bearing manufacturer: What is a rod end joint bearing?

The rod end joint bearing manufacturer said that the joint bearing is a spherical sliding bearing. The basic type consists of an inner ring and an outer ring with a spherical sliding spherical contact surface. The joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, and can withstand large loads. Depending on the type and structure, it can withstand radial loads, axial loads, or a combination of radial and axial loads. The rod end joint bearing manufacturer introduced that the rod end joint bearing is a joint bearing with or mounted on the rod end, which belongs to a category of joint bearings.

The rod end joint bearing manufacturer said that the joint bearing is a spherical sliding bearing. The basic type consists of an inner ring and an outer ring with a spherical sliding spherical contact surface. The joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface, and can withstand large loads. Depending on the type and structure, it can withstand radial loads, axial loads, or a combination of radial and axial loads. Because the outer spherical surface of the inner ring is inlaid with composite materials, the bearing can produce self-lubrication during operation. It is generally used for low-speed swinging motion, and can also be tilted within a certain angle range. When the eccentricity between the support shaft and the shaft housing hole is large, it can still work normally. Self-lubricating joints are used in industries such as water conservancy and professional machinery. Because the spherical sliding contact area of the spherical joint bearing is large and the inclination angle is large, most spherical joint bearings use special processing methods, such as surface phosphating, galvanizing, chrome plating or external sliding surface lining, gasket, spraying, etc. Therefore, it has a large load-bearing capacity and impact resistance, and has the characteristics of corrosion resistance, wear resistance, self-aligning, good lubricity or no lubrication dirt pollution, and can work normally even if it is installed misaligned. Therefore, spherical joint bearings are widely used in swinging motion, tilting motion and low-speed rotation motion.

Spherical bearings and rod end joint bearings have various designs and different sliding contact surface combinations. Each design and combination has unique properties, which makes it particularly suitable for certain applications.

Rod end joint bearing manufacturers said that the vibration of the rod end joint bearing is very sensitive to rod end joint bearing damage, such as peeling, indentation, corrosion, cracks, wear, etc., which will be reflected in the measurement of the vibration of the rod end joint bearing. Therefore, a dedicated rod end joint bearing vibration meter (frequency analyzer, etc.) can be used to measure vibration. ), and the specific abnormal situation cannot be inferred by the frequency score. Since the use conditions of the rod end joint bearing or the installation position of the sensor are different, the measured values are also different, so it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.

Generally speaking, the temperature of the rod end joint bearing can be inferred from the temperature outside the rod end joint bearing chamber. If the outer ring temperature of the rod end joint bearing can be directly measured through the oil hole, it is more appropriate. Usually the temperature of the rod end joint bearing starts to rise slowly with the operation of the rod end joint bearing, and reaches a stable state after 1-2 hours. The normal temperature of the rod end joint bearing varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation position are appropriate, the temperature of the rod end joint bearing will rise sharply and abnormally high temperature will occur. At this time, the operation must be stopped and necessary precautions must be taken. The use of a thermal sensor can monitor the operating temperature of the rod end joint bearing at any time, and when the temperature exceeds the specified value, an automatic alarm or shutdown is realized to prevent shaft burning accidents.
