Abstract
The utility model relates to a high-voltage motor bearing bush structure capable of guaranteeing concentricity and belongs to the technical field of motors. The high-voltage motor bearing bush structure comprises a bearing bush and an end cover. The outer circle of the bearing bush is connected with the end cover through a bolt. The outer circle of the end cover is provided with a spigot. The high-voltage motor bearing bush structure is simple, compact, reasonable and obvious in effect. Under the situation that structure materials are not changed, under the condition that motor mechanical performance characteristics are qualified, the bearing bush and the end cover are machined together, the concentricity of the inner circle of the bearing bush and the end cover spigot is guaranteed, and bearing vibration and noise are lowered.
Description
Technical field
The utility model relates to a kind of high-voltage motor bearing sleeve structure that can guarantee concentricity, belongs to technical field of motors.
Background technology
Motor is the device that converts electric energy to mechanical energy, is widely used in modern various machinery as driving.Particularly high-voltage three-phase asynchronous motor, can be directly used in high-voltage fence, does not need the equipment such as transformer, and it has simplified apparatus, reduces investment outlay, reduces many advantages such as energy consumption.But bear vibration and noise are the factors that affects high-voltage three-phase asynchronous motor quality, for a long time, how to reduce bear vibration and noise, be one of problem of being generally concerned about of technical staff.The method that general high voltage threephase asynchronous reduces bearing noise and vibration is difference machining shaft bearing sleeve, end cap, guarantees its machining accuracy as far as possible, but does like this, can only reduce nonconcentricity, cannot guarantee that bearing holder (housing, cover) connects the concentricity after end cap.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of high-voltage motor bearing sleeve structure that can guarantee concentricity is provided, and is guaranteeing, under electromechanics performance characteristics acceptance condition, to guarantee the concentricity that bearing holder (housing, cover) and end cap are installed.
The technical scheme providing according to the utility model, the high-voltage motor bearing sleeve structure that can guarantee concentricity comprises bearing holder (housing, cover) and end cap, bearing holder (housing, cover) inner ring is installed bearing, bearing holder (housing, cover) both sides are connection bearing inner cap and bearing end cover respectively, internal bearing cover and bearing end cover by bearing seal in bearing holder (housing, cover), it is characterized in that: bearing holder (housing, cover) outer ring is bolted end cap, end cap outer ring is provided with seam.
Further, between end cap and bolt, be provided with packing ring.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure, and action effect is obvious; The in the situation that of change structure material not, guaranteeing that under electromechanics performance characteristics acceptance condition, bearing holder (housing, cover) is processed together with end cap, guarantee the concentricity of bearing holder (housing, cover) inner circle and end cap seam, reduce bear vibration and noise.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals: 1-internal bearing cover, 2-bearing, 3-bearing holder (housing, cover), 4-end cap, 5-bolt, 6-packing ring, 7-bearing end cover, 8-seam.
Embodiment
The utility model is further described in connection with the embodiment in accompanying drawing below:
As shown in Figure 1, the utility model mainly comprises bearing holder (housing, cover) 3 and end cap 4, and bearing holder (housing, cover) 3 outer rings connect end cap 4 by bolt 5, between end cap 4 and bolt 5, are provided with packing ring 6.
Described bearing holder (housing, cover) 3 inner rings are installed bearing 2, and bearing holder (housing, cover) 3 both sides are connection bearing inner cap 1 and bearing end cover 7 respectively, and internal bearing cover 1 and bearing end cover 7 are sealed in bearing 2 in bearing holder (housing, cover) 3.
Described end cap 4 outer rings are provided with seam 8, take seam 8 as machining benchmark on lathe, and machining shaft bearing sleeve inner circle can guarantee the concentricity of end cap and bearing holder (housing, cover).
Bearing holder (housing, cover) of the present utility model is rough turn inner circle on lathe first, and all the other process by drawing, after end cap processes on lathe, link together by bolt, packing ring with bearing holder (housing, cover), and then on lathe, to take the seam of end cap is benchmark finish turning bearing holder (housing, cover) inner circle; Then, the connector of end cap and bearing holder (housing, cover) is assembled together with bearing, internal bearing cover 1, bearing end cover.Owing to take the seam of end cap, be benchmark finish turning bearing holder (housing, cover) inner circle, just guaranteed the concentricity of end cap and bearing holder (housing, cover), the reduction bearing noise and the vibrating effect that obtain are obvious.
