Equipment installation requirements of rolling bearing apparatus

Pre-installation of rolling bearings, bearing scale cooperation should be measured, according to the way rust bearings composite bearings to select the appropriate way to wash clean; bearings should be no damage, no rust, no scrolling should be sensitive and abnormal movement.
2. Use temperature difference method when installing bearings, bearing sliding bearing temperature should not be heated above 100 ℃; cooling temperature is not lower than / 80 ℃.
3. Skills equipment Rules document bearing outer ring and bearing housing bore or cooperation should be fit. About split housings or open tank, split joints should be no gap; bearing outer ring and bearing center line of symmetry in size and bearing cap 120 ° in 90 ° symmetrical centerline of scale should be uniform touch, and should be used 0.03mm feeler, stuffing length should be less than 1/3 of the length of the outer ring. You must not have room bearing outer ring and bearing housing or open the folder with the help of mixed hole appearance.
4. The bearing and shaft shoulder or shoulder bearing profile should try to be; tapered roller bearings and angular contact ball bearings and shaft shoulder gap no larger than 0.05mm, the gap with the other bearing must not be greater than 0.1mm. Bearing cap and flat washers necessary, and should be evenly close to the end face of the bearing. When the device files skills regularly, according to the rules leave gaps.
5. Install the shaft ends with radial clearance is not adjustable, axial displacement and the axis of the head cover is restricted when the two radial bearings, should stay out of the gap. When the device file no skill rules, leaving gaps desirable 0.2 ~ 0.4mm.
6. The radial bearings, needle bearings, roller screw should be sensitive after rolling bearings installed. When selecting the bearing grease in the bearing cavity should be raised after the installation of 65% to 80% of the cavity volume of cleaning grease, but oil lubrication of bearings, lubrication can not.
7. A single row radial ball bearings, radial thrust tapered roller bearings, angular contact ball bearings mounted on the journal bearing and axial preload level within the (axial pre-interference), should be standardized or bearing rule device files skills to perform.
