Yuncheng slewing bearing... / ' (3,3,3) - From the perspective of both users and manufacturers, it is reasonable to install the upper and lower ring soft belts of the slewing bearing in a better position. Therefore, the location requirements for soft belt installation will essentially be to increase the life of the bearing. The manufacturer of the slewing bearing should accurately mark the position of the soft belt of the slewing bearing, and the manufacturer and installer should reasonably install the position of the soft belt of the slewing bearing as needed.
/ ' (3,3,3) - This requires the user who uses and selects the slewing bearing device to reasonably install the position of the soft belt. Four: Because there is a certain possibility of the soft belt on the slewing bearing device. . To improve the service life of bearings. The general principle is to try to install the soft belt in a position where the soft belt will bear the least pressure during load changes. Usually the upper ring soft belt of the slewing device is installed at a position perpendicular to the projection line of the pitch rotation plane. For example, the upper ring soft belt of the slewing device of a ship loader or stacker-reclaimer should be installed at a position perpendicular to the center line of the cantilever and cutting through the center of rotation. , that is, the position facing the left or right side of the cantilever while standing on the center of rotation. In the usual mechanical design, the soft belt does not have the maximum stress state of the support roller of the slewing bearing device at this position. The installation position of the lower ring soft belt of the slewing device should be determined according to the center of gravity of the equipment and the range of rotation angles. If the angle of rotation is left and right degrees, and the maximum center of gravity of the part above the rotation is in the front, it is recommended to install the lower ring soft belt at the rear, that is, in the degree position. If the local center of gravity change position above the slewing bearing is equal in the front and rear positions, the angular position of the lower ring soft belt can be arbitrarily set.
