QWhat is THE BASIC MECHANISM OF SLEWING RING BEARING?

ASlewing drive is usually composed of worm, slewing bearing, shell, motor and other components. Because the core parts are rotary bearings, they can bear axial force, radial force and overturning moment at the same time. There are many forms, but the structure is basically the same. From left and right are (upper part): 1. Outer ring (toothed or toothless); 2. Sealing belt; 3. Rolling body (rolling ball or roller); 4. Oil nozzle from left and right are (lower part): 1. Plug; 2. Plug pin; 3. Inner ring (toothed or toothless); 4. Isolation block or cage; 5. Installation hole (wire hole or smooth hole)

QWhat are THE INSTALLATION STEPS OF THE SLEWING BEARING?

ABefore the installation of the rotary table bearing, the installation surface of the main engine shall be inspected first, and the supporting parts shall have sufficient strength. The joint surface shall be machined and flat without sundries and burrs. If the required flatness cannot be achieved by machining, Special plastics with high injection strength can be used as fillers to ensure the accuracy of installation plane and to reduce vibration. The ring of the rotary table bearing has a quenching soft belt area, which is marked with "s" on the end face of the ring. When the user installs it, he should The soft belt is located in the non load area or non frequent load area (the plug hole is always located in the soft belt). When installing the bearing of the rotary table, the radial positioning shall be carried out first, the mounting bolts shall be tightened crosswise, and the rotation of the bearing shall be checked. Sufficient pre tightening force shall be provided when tightening the bolt, and the pre tightening force shall be 70% of the yield limit of bolt material. Mounting bolts shall be equipped with It is forbidden to use spring washer for tempering flat washer.
