Abstract
The invention relates to a method for processing a high-voltage motor bearing sleeve, which comprises the following steps: roughly lathing the inner circle of a bearing sleeve by a lathe and then processing an end cover by the lathe; connecting the bearing sleeve and the end cover by a bolt and a gasket to form a connecting body; positioning by adopting an end cover stopper opening as a reference; finely lathing the inner circle of the bearing sleeve by the lathe; finally connecting the connecting body and a bearing and connecting the an inner cover of the bearing and an outer cover of the bearing for assembly. The invention ensures the concentricity of the inner circle of the bearing sleeve and the end cover stopper opening by the method for processing the bearing sleeve and the end cover together, positioning by adopting the end cover stopper opening as the reference and finely lathing the inner circle of the bearing sleeve, reduces the vibration and the noise of the bearing and has simple and compact structure and obvious effect.
Description
Technical field
The present invention relates to motor, be specifically related to the bearing holder (housing, cover) of high-voltage motor.
Background technology
Motor is the device that converts electric energy to mechanical energy, is widely used in the modern various machinery as drive unit.Particularly high-voltage three-phase asynchronous motor can directly apply to high-voltage fence, does not need equipment such as transformer, advantage such as have simplified apparatus, reduce investment outlay, cut down the consumption of energy.But bear vibration and noise are the principal elements that influences the high-voltage three-phase asynchronous motor quality, for a long time, how to reduce bear vibration and noise, are one of problems of generally being concerned about of technical staff.The traditional reduction high-voltage three-phase asynchronous motor bearing noise and the method for vibration are that machining bearing overlaps and end cap respectively, guarantee its machining accuracy as far as possible, but do like this, can only both nonconcentricity of limited reduction, can't accurately guarantee the concentricity after bearing holder (housing, cover) connects end cap.
Summary of the invention
Be connected the problem that the back concentricity can't guarantee with end cap at existing high-voltage motor bearing sleeve, the applicant improves through research, a kind of processing method of high-voltage motor bearing sleeve is provided, guaranteeing under the qualified condition of electromechanics performance characteristics, utilize simple and effective measure, guarantee the concentricity of bearing holder (housing, cover) and end cap.
Technical scheme of the present invention is as follows:
A kind of processing method of high-voltage motor bearing sleeve may further comprise the steps:
Useful technique effect of the present invention is:
The present invention is not changing structural material, with under assurance electromechanics performance characteristics acceptance condition, by bearing holder (housing, cover) and end cap method for processing together, blocking the end cap seam with support, is that benchmark positions with the end cap seam, thus circle in the finish turning bearing holder (housing, cover), guaranteed the concentricity of interior circle of bearing holder (housing, cover) and end cap seam, reduced bear vibration and noise, simple in structure, compact, effect is obvious.
Description of drawings
Fig. 1 is a flow chart of the present invention.
Fig. 2 is the bearing arrangement schematic diagram after machining.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Fig. 1 shows idiographic flow of the present invention, the bearing arrangement schematic diagram after Fig. 2 shows and machines.As shown in Figure 1 and Figure 2, at first in step S101, with the interior circle 8 of the rough turn bearing holder (housing, cover) 3 of lathe; Then in step S102, with machined into end cap 4; All the other parts process by drawing; Next in step S103, the end cap 4 that processes among the bearing holder (housing, cover) 3 that processes among the step S101 and the step S102 is linked together by bolt 6, packing ring 5, form a connector; In step S104, be benchmark with the connector that processes among the step S103 with the seam on the end cap 9, block the location with support, use machined into again, the interior circle 8 of finish turning bearing holder (housing, cover) 3; At last in step S105, the connector of the end cap 4 that processes among the step S104 and bearing holder (housing, cover) 3 and bearing 2, internal bearing cover 1, bearing end cover 7 are linked and packed by prior art, flow process so far of the present invention finishes.
Fig. 2 shows the bearing arrangement schematic diagram that adopts after the present invention machines.As shown in Figure 2, this bearing is made up of internal bearing cover 1, bearing 2, bearing holder (housing, cover) 3, end cap 4, packing ring 5, bolt 6, bearing end cover 7, and there is seam 9 at the edge of end cap 4, and this bearing arrangement is identical with bearing arrangement of the prior art.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
