What are the installation of the spherical bearing need to be aware of

Any parts of the machine installation should pay attention to methods and skills, or it will lead to failure or make the normal operation of the machine installation. This article mainly introduce the installation notes in the spherical bearing, hoping to bring some help to the related people. To facilitate the installation of spherical sliding bearing and the pin or shaft and bearing hole edge should be the end of 20 ° 10 ° to the lead tank. Bearing can be easier to pressure into the in place, and bearing tilt to the risk of damage to the fitting surface is very small. When installing a fracture or two parts of outer spherical bearing, joint must be positioned in 90 ° in the direction with the main load position; Otherwise, will shorten the service life, especially in the case of heavy load. In addition, will be placed in the load bearing lubrication hole area, allows allocation of lubricant in the most needed areas. Shall not be bearing ring hammer into place. Only install force imposed on the ring is installed ( That is, if the outer pressure into the shell, the external ring force f; If the inner pressure into the shaft of the inner ring force f) 。 Do not through the bearing force of sliding surface applied to install, it will damage the bearing and seriously reduce its service life. If the bearing on the inner and outer ring are press fit, you should use a special tool into two parts at the same time. Also can use other installation, convenient and heating or cooling, or use the glue, please contact the AST engineering department for further help. Usually, the spherical bearing outer ring pressed into the bearing seat. This makes the fracture keep closed, and prevent the outer ring spinning under heavy rotation or vibration load. The inner ring on the shaft may have interference fitted or clearance fit, depending on the application.
