Many customers know that angular contact ball bearings are generally used in pairs, so what are the specific steps for pairing angular contact ball bearings? This article will give you a detailed introduction, the following steps are suitable for universal matching angular contact ball bearings. Step 1: Ensure that the installation environment, shaft, bearing seat and other components are cleaned; Step 2: Accurately measure the specifications of the shaft and bearing seat, cylindricity, vertical angle of the collar, etc. Step 3: Turn on angular contact The outer packaging of the ball bearing, wipe off the anti-rust oil on the inner and outer rings, and carry out the appearance inspection of the bearing; Step 4: The installation position of the angular contact ball bearing needs to be installed correctly, and it must be installed back-to-back; Step 5: Use an electric heater to add Warm bearing to ensure that on the inner ring of the temperature measurement camera, two paired double-row angular contact ball bearings should be heated together; in general, the ambient temperature of the bearing is 70°C higher than that of the shaft, and the maximum ambient temperature of the bearing cannot exceed 120°C . (The bearing must be demagnetized) Step 6: Install angular contact ball bearings, and install 2 pairs of single-row bearings together; Step 7: Use a wrench and a lock nut to manually lock the bearing to a suitable position to ensure that the inner circle is tightened on the shaft Shoulder, the inner circles of the two paired angular contact ball bearings are in close contact with each other; (the lock nut is not added at this time) Step 8: Wait for the bearing to cool down to the room temperature; Step 9: Remove the lock nut and install it Lock the nut, and then install the nut, the standard allows, you can apply a layer of floating oil on the rounded corner of the lock nut; Step 10: Install the nut to the appropriate position, lock it with a wrench, and manually screw it. In this case, you can use a hammer to tighten another 1/8 - 1/4 turn to remove the gap formed in the whole refrigeration process; Step 11: Find the lock nut foot closest to the lock nut groove, if not two To align the ends, it is not necessary to loosen the lock nut to align the lock grooves at both ends. You can lock the nut again to align with the two ends of the recent sealing ring feet, and then bend the sealing ring feet to the groove body; Step 12: Installation , Rotate the bearing manually to check whether there is poor operation, excessive torque, unstable torque, etc. The thirteenth step: If the next step is not carried out immediately, cover and protect the parts to prevent debris from entering. Step 14: For the angular contact ball bearing with back-to-back layout, the outside fixation can be relatively loose and stable in the bearing seat, preferably with a radial side clearance of 0.00~0.05mm. The torque is accurate, in order to turn stable!
