What are the steps in the auto water pump bearing of bearing installation when installation, must equal pressure on the circumference of the ring width, to press the ring into, can not use ð ¨ + top tools directly on bearing face, in order to avoid damage
Clearance value should be used according to different conditions and cooperate with the amount of interference and specify the size.
When necessary, shall be tested to determine.
At the same time, nut or other appropriate method is applied to tighten the bearing, in order to prevent the bearing width after cooling contraction and make the ring gap between shoulder and produce single row circular cone roller bearings installed last should undertake clearance adjustment.
Fashionable, should guarantee the outer end face and the shell shoulder end face, inner ring end face and the shaft shoulder end face pressure, there is no gap.
Running test normal rear deliverables.
When large amounts of interference, can use oil bath heating or sensor heating method to install the bearing, the heating temperature range of 80 ℃ -
More than 120 ℃, 100 ℃, the highest can't.
Bearing installation should rotate after the test, first of all to the axis of rotation or bearing box, without exception, with a power of no load, low speed, then according to the condition of operation gradually increase the speed and load, and detection noise, vibration and temperature rise, found abnormal, should stop and check.
