The adjusting device of internal space ring and external space ring as shown in Figure 1 when angular contact bearing of the present invention " face-to-face " was installed: device comprises base 13, digital display type pull and push dynamometer 17, bearing block 9, warm-air drier 10, thermometric RTD 2, heating plate 3, pretightning force balancing weight 4 and push rod 1.Bearing block 9 is connected connection by mat insulation 12 usefulness screws 11 with base, digital display type pull and push dynamometer 17 is contained on the slide plate 14,13 guide rail is connected on slide plate 14 and the base, eccentric wheel handle 15 is connected on the base 13 by bearing pin 16, breach on the warm-air drier 10 aiming axis bearings 9,2 thermometric RTDs 2 and 2 heating plates 3 are attached to respectively on bearing block 9 and the pretightning force balancing weight 4, push rod 1 is placed in the middle of the bearing block 9 of hollow, one disk is arranged on the push rod, and disk can promote bearing inner spacer 7 when push rod swings.Upper bearing (metal) 5 and lower bearing 8 are placed in the middle cavity of bearing block, lay cone spacer 7 and outer ring spacer 6 between upper bearing (metal) 5 and the lower bearing 8, are pressed with pretightning force balancing weight 4 on whole bearing is right.Described pretightning force balancing weight 4 comprises calibration balancing weight 4-1 and adjusts balancing weight 4-2 that the weight of wherein adjusting balancing weight 4-2 is 2 times of calibration balancing weight 4-1.
The method of adjustment of angular contact bearing internal space ring and external space ring comprises that step is as follows:
1) opens warm-air drier 10 and heating plate 3, bearing to being heated to predetermined temperature, and was stablized 20 minutes;
2) demarcate first the relation of axial pre tightening force and spacer ring frictional force, timing signal, pair of bearings and cone spacer 7 are contained on the bearing block, calibration balancing weight 4-1 is pressed in bearing to upper, the digital display type pull and push dynamometer promotes push rod and swings, disk on the push rod drives the cone spacer slippage, thereby records the demarcation frictional force of corresponding cone spacer under one times of pretightning force;
3) add dress outer ring spacer 6, and be pressed in bearing to upper with the adjustment balancing weight 4-2 of two times of weights, the power of two times of reprovision pouring weights divides two the tunnel to transmit: the one tunnel to cone spacer 7, another road is to outer ring spacer 6, repeating step 1, behind the temperature stabilization, the digital display type pull and push dynamometer is measured the frictional force of cone spacer again;
4) less than demarcating frictional force if again measure the frictional force of cone spacer, repair thin outer ring spacer 6, otherwise, repair thin cone spacer 7;
5) remeasure the frictional force of cone spacer, if frictional force with to demarcate frictional force inconsistent, repeating step 4 is if the frictional force of surveying is adjusted end with to demarcate frictional force identical.
The invention has the advantages that:
Because the frictional force of spacer ring is very responsive for pretightning force (normal pressure), so poor more accurate with the method check cone spacer and outer ring spacer thickness.This verifying attachment is simple in structure, lightweight, volume is little, reliability is high.
