Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
Fig. 3 is the flow chart of assembly method according to the invention; Mounting structure in conjunction with Fig. 1, electric motor end cap formula sliding bearing shown in Figure 2; Be that said electric motor end cap formula sliding bearing is for dividing body structure; The bearing pedestal of said sliding bearing comprises the bearing seat of honour 3 and bearing base 2, and the bearing shell of said sliding bearing comprises following watt 6 on axle Shang watt 4 and axle, and assembly method according to the invention comprises following steps:
A, bearing base 2 and end cap 5 are installed the seam facing-up;
B, facing-up is carried out in axle on watt 4 and the bearing seat of honour 3, rotating shaft 1, following watt 6 on axle is carried out facing-up with bearing base 2, rotating shaft 1;
C, axle is packed into for following watt 6 in the bearing base 2, installation shaft on watt 4 with the bearing seat of honour 3 and bearing base 2 zoariums, is measured the magnitude of interference between said bearing shell and the said bearing pedestal, and carries out magnitude of interference adjustment;
D, the bearing seat of honour 3 and bearing base 2 are disintegrated; Through sliding scale bearing base 2 is installed; Be about to bearing base 2 lift or sling after with its left-hand thread to rotating shaft 1; The said installation seam of bearing base 2 and the said installation seam on the end cap 5 align, and following 2 on sliding bearing is installed to relevant position on the end cap 5 said seams with bearing base 2; Through following watt 6 of oil lubrication method installation shaft, promptly moderate lubrication oil is smeared at watts 6 the back side under axle, and axle is installed in the bearing base 2 for following watt 6 smoothly; The installation shaft on watt 4 and the bearing seat of honour 3 again;
E, use dish modulation heart method are adjusted the position of said bearing shell in said bearing pedestal, promptly on the spindle nose of rotating shaft 1, screw are installed, and prize screw and make rotating shaft 1 rotation, adjust the position of said bearing shell in said bearing pedestal;
F, the bearing seat of honour 3 is urgent and be fastenedly connected with bearing base 2 location is in place other parts.
Particularly, in the A step, bearing base 2 and end cap 5 are installed the seam facing-up, the end cap 5 and the installation seam contact area of bearing base 2 are increased, can strengthen the stability and the rigidity of said bearing pedestal, reduce bearing vibration;
In the B step,, following watt 6 on axle and bearing base 2, rotating shaft 1 are carried out facing-up through facing-up is carried out in axle on watt 4 and the bearing seat of honour 3, rotating shaft 1; Can improve the distribution of lubricating oil film; Improve the lubrication property of bearing, thereby reduce the possibility of bearing tile kilning, and reduce bearing vibration;
In the C step, high clearance gauge methods such as employing are measured the magnitude of interference between said bearing shell and the said bearing pedestal, are about to the bearing seat of honour 3 and disintegrate with bearing base 2; Axle is packed into for following watt 6 in the bearing base 2, and the position at four angles on bearing base 2 amalgamation faces is placed a clearance gauge respectively, and guarantees four height such as clearance gauge; Then between the axle on watt 4 and the bearing seat of honour 3, put into a galvanized wire, the installation shaft on watt 4 and the bearing seat of honour 3, and between the two, put into a galvanized wire equally; And following watt 6 on lock shaft on watt 4 and axle; Locking action makes the thickness of said galvanized wire that certain variation arranged, and with axle on watt 4 and 3 dismountings of the bearing seat of honour, takes out said galvanized wire again; And the thickness of said galvanized wire measured, through the said magnitude of interference of measuring of outcome measurement.And the situation of the said magnitude of interference of needs adjustment mainly is meant the situation that the magnitude of interference is too small, at this moment, and can be through in-migration under the center of bearing base 2 be adjusted the said magnitude of interference.Through the adjustment of the magnitude of interference, can reduce bearing vibration;
In the D step, through sliding scale bearing base 2 is installed, on the bearing guard of rotating shaft 1, place one of soft silicon rubber slab earlier, can make bearing base 2 be in place through said sliding scale, and avoid the bearing guard of rotating shaft 1 to sustain damage; Through following watt 6 of said oil lubrication method installation shaft, it is easy to operate and do not damage the insulating barrier of said bearing pedestal; When the installation shaft on watt 4 and the bearing seat of honour 3, require to install and lock shaft on watt 4, install but do not lock the bearing seat of honour 3;
In the E step, change centralizing method through said dish and adjust the position of said bearing shell in said bearing pedestal, can reduce the possibility of bearing tile kilning, reduce bearing vibration;
In the F step, urgent with tight between the bearing seat of honour 3 and the bearing base 2 with alignment pin with the bolt handle, other parts are in place.
More than describing is to explanation of the present invention, is not that institute of the present invention restricted portion within protection scope of the present invention, can be done any type of modification referring to claim to the qualification of invention.
