Slewing bearing device /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Before the slewing bearing device; first check the surface of the main unit; the required support should have the required strength; the joint surface should be machined; the surface is smooth without debris and burrs. The machine can not be machined to the required flatness. It can be used as a filler with special plastic with high writing strength; to ensure the accuracy of the plane of the device and to reduce vibration.
The ferrule bearing ferrule has a quenching soft belt zone; this has the symbol "S" on the end face of the ferrule; the device should be placed in a non-load zone or a very normal load zone (the plug hole is always soft) With).
When installing the slewing bearing; it should be positioned in the radial direction; insert the tightening device 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 data yield limit. Bolts shall be fitted with tempered flat washers and the use of spring washers shall be prohibited.
2 protection of slewing bearings
After 100 hours of continuous operation, the slewing bearing that is installed and put into operation should check whether the pre-tightening torque of the device bolt meets the requirements; in the future, repeat the above-mentioned inspection once every 500 hours.
The slewing bearing device should be filled with excess grease at the end; 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; The bearing should make up one grease after 50~100 hours per distance.
3 The slewing bearing transport and storage bearings are in the process of transport; should be placed horizontally on the vehicle; there should be ways to avoid slipping and avoid oscillation; if necessary, add auxiliary support.
The bearings should be placed horizontally in a dry, ventilated and leveled place; they 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 placed evenly along the circumferential direction. More than one level of 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-proof disposal.
