Abstract
The present invention relates to a kind of installation method of bearing, using the papery adjustment ring of non-close, with the characteristics of tension force is big, damping property is good, simultaneously because papery adjustment ring material property and height lengthen the effect of guiding, while beneficial to installing, overcome completely difficult when press-fiting between traditional bearing and bearing saddle bore because being interference fitted in or because the adjustment ring that magnitude of interference ambassador closes is extruded the problem of cracking, it is ensured that bearing and the fit precision of bore, improve bearing assembling quality and functional reliability.
Description
Technical field
It is particularly a kind of to be easily installed and accurately ensure the bearing coordinated the present invention relates to a kind of installation method of bearing
Installation method.
Background technology
Outer race is generally when coordinating with bearing saddle bore and is directly engaged, have for ensure bearing long-term stable operation
And the stabilization of bearing end-play, design has used the regulation ring along week closing of plastic material in bearing saddle bore, due to axle
Hold and there is the magnitude of interference between outer shroud and regulation ring, outer shroud is difficult because guiding be not just pressed into or sometimes because the magnitude of interference is big in assembling
Cause the regulation ring of plastic material to produce embrittlement, influence the stability of bearing working.
The content of the invention
It is an object of the invention to provide a kind of installation method of bearing, that is, ensure that the cooperation between bearing outer ring and bore will
Ask, be easy to the convenient installation of outer race and bore again.
The present invention concrete technical scheme be：The installation method of described bearing comprises the following steps：
1st, according to the bearing outside diameter D used, the bearing mounting hole of bearing block is processed, the nominal size of described bearing mounting hole is
Increase by 0.4 on the basis of bearing outside diameter nominal size, the tolerance upper deviation is that+0.04, lower deviation is 0；
2nd, design and process adjusting pad, described adjusting pad is a rectangular paper washer, material selects 0.3mm DK100/100
Eleatrical insulating board, the length of adjusting pad is less than the external diameter total length 0.2mm from bearing, and adjusting pad width is in bearing thickness
On the basis of increase by 4~5mm, adjustment mat thickness carry out grinding, nominal value is 0.25mm, according to the bearing mounting hole of bearing block
Tolerance range packet, first group of tolerance is+0.01, and second group of tolerance is group thickness of -0.01, i.e., first (0.24~0.25) mm,
Second group of thickness (0.25~0.26) mm；
3rd, the spacer of the suitable group of bearing mounting hole size selection of bearing block is pressed, the bearing of outer race and bearing block 2 is pacified
The cooperation for filling hole is controlled between (0.06~0.1) mm；
4th, adjusting pad is curved into annular to be put into the bearing mounting hole of bearing block, is allowed to fit with bearing mounting hole inwall, then
Outer race is pressed into in place；
5th, after outer race is installed in place, the part that adjusting pad is higher by bearing surface is reduced with cutter, completes bearing peace
Dress assembling.
The present invention, due to " papery " adjustment ring using non-close, the material is by wood pulp, cotton pulp mixing compacting, tension force
Greatly, damping property is good, simultaneously because " papery " adjustment ring material property and height lengthen the effect of guiding, beneficial to the same of installation
When, overcome difficult when press-fiting between traditional bearing and bearing saddle bore because being interference fitted in or close because of magnitude of interference ambassador completely
Adjustment ring is extruded the problem of cracking, it is ensured that bearing and the fit precision of bore, improve bearing assembling quality and work
Make reliability.
Brief description of the drawings
Fig. 1 is the bearing block structure schematic diagram that embodiment of the present invention is related to；
Fig. 2 is that adjusting pad is loaded into bearing saddle bore and bearing schematic diagram is pressed into；
Fig. 3 is that bearing finally assembles the schematic diagram finished.
Embodiment
As illustrated, the installation method of described bearing comprises the following steps：
1st, according to the outer diameter D of bearing 1 used, the bearing mounting hole of bearing block 2, the nominal chi of the described mounting hole of bearing 1 are processed
Very little is to increase by 0.4 on the basis of the external diameter nominal size of bearing 1, and the tolerance upper deviation is that+0.04, lower deviation is 0；
2nd, design and process adjusting pad 3, described adjusting pad 3 is a rectangular paper washer, material selects 0.3mm DK100/
100 eleatrical insulating board, the length of adjusting pad 3 is less than the external diameter total length 0.2mm from bearing 1, and the width of adjusting pad 3 is in bearing
Increase by 4~5mm on the basis of 1 thickness, the thickness of adjusting pad 3 carries out grinding, and nominal value is 0.25mm, according to bearing block 2
The tolerance range packet of bearing mounting hole, first group of tolerance is+0.01, and second group of tolerance is group thickness of -0.01, i.e., first (0.24
~0.25) mm, second group of thickness (0.25~0.26) mm；
3rd, the spacer 3 of the suitable group of bearing mounting hole size selection of bearing block 2, the bearing of the outer shroud of bearing 1 and bearing block 2 are pressed
The cooperation of mounting hole is controlled between (0.06~0.1) mm；
4th, adjusting pad 3 is curved into annular to be put into the bearing mounting hole of bearing block 2, is allowed to fit with bearing mounting hole inwall, so
The press-in outer shroud of bearing 1 is in place afterwards；
5th, after the outer shroud of bearing 1 is installed in place, the part that adjusting pad 3 is higher by the surface of bearing 1 is reduced with cutter, bearing is completed
1 installs assembling.
