  Check the operation of the Roller Bearing

  After the installation of the Roller Bearing, 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, poor installation of the installation of the rotating torque is uneven, by the clearance is too small, the installation of the error caused by sealing friction and so on The If there is no exception, you can start the power operation.

  Because the large machine can not manually rotate, so no load immediately after the power off, the 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 increasing to the rated condition rated operation. Check the operation of the inspection, whether there is abnormal sound, Roller Bearing 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 Roller Bearing inspection.

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