Device method: Before the TIMKEN bearing slewing bearing device; first check the device surface of the main machine; the required support member should have the required strength; the connecting surface should be machined; the appearance is smooth without debris and burrs. The flatness of the demand; the special plastic with high writing strength can be used as the filler; to ensure the accuracy of the plane of the device and to reduce the vibration. The ferrule of the TIMKEN bearing slewing bearing has a hardened soft zone; this is at the end face of the ferrule The symbol "S" is provided on the device; the device should be placed in the non-load zone or the very normal load zone (the plug hole is always located at the soft belt). When the slewing bearing is installed; the radial direction should be advanced; Install the bolt; and check the reverse condition of the bearing. The tightening force should be satisfied when tightening the bolt; the pre-tightening force should be 70% of the bolt material's compliance limit. The bolt should be equipped with a smoothing washer and the spring is prohibited. washer.
Protection: TIMKEN bearing slewing bearing installed and put into operation after 100 hours of continuous operation; should check all the pre-tightening torque of the device bolt to meet the demand; in the future, repeat the above-mentioned inspection once every 500 hours. The slewing bearing device should be filled at the end. Excessive grease; and the bearing should be reversed while filling to make the grease evenly distributed. After the slewing bearing is in operation for a period of time; inevitably, a part of the grease will be lost; therefore, the slewing bearing in normal operation is 50-100 per distance. After a few hours, you should make up one grease.
Storage: TIMKEN bearings should be placed horizontally in a dry, ventilated and flat place; should be separated from chemicals and other corrosive materials during storage. If multiple sets of bearings are required to be stacked, each set should be circumferentially Evenly place more than three height-flat wooden blocks; and the upper base blocks are placed together. Bearings that need to be continuously stored beyond the anti-rust period should be removed from the head and rust-proofed.
