What are joint bearings
Joint bearing is a kind of spherical plain bearing, its sliding contact surface is an inner sphere and an outer sphere, which can rotate and swing at any Angle when moving. It is made of surface phosphating, blasting, inserts, spraying and other special processing methods. Joint bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and so on.
Characteristics of joint bearings
Joint bearings can bear large loads. Depending on its type and structure, it can bear radial load, axial load or a combination of radial and axial loads. Because the outer sphere of the inner ring is inlaid with composite material, the bearing can produce self-lubrication in operation. Generally used for low speed swing movement, and low speed rotation, can also be in a certain Angle range for inclined movement, when the supporting shaft and shaft shell hole is not concentricity is large, it can still work normally. Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.
Method for loading and unloading and lubrication of joint bearings
1. loading and unloading: the loading and unloading of plain bearings should follow the following principle, that is, the force exerted by assembly and disassembly cannot be transferred directly through the spherical sliding surface. In addition, auxiliary loading and unloading tools, such as sleeves and dismounters, should be used to directly and evenly apply the loading and unloading force imposed by the outside world to the matched rings, or use auxiliary methods such as heating for loadless loading and unloading. When assembling joint bearing series, it is necessary to pay special attention to the position of the outer ring dividing surface. In order to avoid the load acting directly on the segmentation surface, the segmentation surface should be maintained at right angles to the coincidence direction.
2. Lubrication: when the load and the speed generated by the swing movement are very small, the oil feeding type joint bearing can be operated without lubrication. However, it is generally necessary to supplement fats regularly. In the initial installation operation, it is recommended that the lubrication period be moderately shortened. No oil feed type plain bearings can be used in the case of no lubrication. However, if lithium soap-based grease is added before operation, the service life of joint bearings can be extended more. If grease is injected into the space around the bearing, the joint bearing will be more effective in preventing the invasion of dust and foreign bodies.
