Check The Operation Of The Slewing Bearings

  Check the operation of the Slewing Bearings

  After the installation of the Slewing Bearings, in order to check whether the installation is correct, to carry out the operation check, small machinery can be rotated to confirm whether the rotation is smooth. Check the project due to foreign body, scars, indentation caused by poor operation, due to poor installation, the installation of poor machining and the resulting rotation torque uneven, by the clearance is too small, the installation of the error caused by friction and other large torque The If there is no exception, you can start the power operation.

  Because the large machine can not manually rotate, so immediately after the start off the load without power, inertia operation, check whether the vibration, sound, rotating parts are contact, etc., to confirm no abnormal power into the operation.

  Power running, starting from the no-load low speed, slowly raised to the rated conditions rated operation. Check the operation of the test, whether there is abnormal sound, Slewing Bearings temperature transfer, lubricant leakage and discoloration and so on. In the test run if you find abnormal, should immediately stop running, check the machine, if necessary, to remove the Slewing Bearings inspection.

  The Slewing Bearings temperature check is generally known from the appearance of the housing. But the use of oil hole, direct measurement of Slewing Bearings outer ring temperature, more accurate. Slewing Bearings temperature operation began to rise gradually, if no abnormalities, usually 1 to 2 hours after the stability. If the Slewing Bearings or installation and other bad, the Slewing Bearings temperature will rise sharply, abnormal high temperature. The reasons such as excessive lubricant, Slewing Bearings clearance is too small, poor installation, sealing device friction is too large and so on. High-speed rotation of the occasion, the choice of Slewing Bearings lubrication method is also the reason for the wrong.
