Description
Technical field
The utility model relates to the stepping motor technical field, and especially a kind of shaft has the stepping motor of dust reduction capability.
Background technology
Stepping motor is widely used in automatic control at present, light of stage, and textile machine, Medical Instruments, machining etc. industry, because the machining accuracy of stepping motor is high, step angle is less, belongs to high-precision motor, and use occasion is that requirement for environmental conditions is higher.Development along with the applied science technology, the chemical industry that some environment for use conditions are more severe, outdoor workplace, as monitoring, The Cloud Terrace etc. also needs to use the high accuracy stepping motor, because the degree of protection of the mechanical structure of present stepping motor is not high, therefore use present stepping motor under adverse circumstances, often dust can enter from the shaft of motor motor bearings and motor internal, motor bearings is very easily damaged, inner part is corroded, motor performance descends, rotor is stuck, the insulating motor coil grade reduces, cause coil inside to puncture or short circuit etc. situation, cause motor very short time to sustain damage, therefore equipment damage, cause very big loss.
The dust protection that how to improve stepping motor is a urgent problem.Some improve the method for the dust protection of stepping motor, as outside motor covering protective casing, at bearing chamber, add elasticity oil sealing etc., although can improve the dust degree of protection of motor, but because electric machine structure is huge, expense increases, and this is not a kind of design of cost performance preferably.
The structure of stepping motor end cap, find that most of dust is to infiltrate motor bearings and motor internal at stepping motor shaft and bearing place basically at present.Therefore solve the stepping motor dust and infiltrate problem and take more corresponding measures, the dust degree of protection of stepping motor can be improved greatly, can make stepping motor among severe dust atmosphere, as dust atmosphere, and field operation etc. occasion.
The utility model content
In order to overcome the poor deficiency of existing stepping motor dirt exclusion capabilities, the utility model provides a kind of shaft to have the stepping motor of dust reduction capability.
The utility model solves the technical scheme that its technical problem adopts: a kind of shaft has the stepping motor of dust reduction capability, comprise motor stator, front end housing, bearing, axle and bearing chamber, described motor stator front side is provided with front end housing, be provided with bearing chamber in described front end housing, be provided with bearing in described bearing chamber, described axle is through the through hole on bearing, described bearing packing washer makes packing ring compress dust-proof seal ring, make the end face of dust-proof seal ring be close to the bearing locular wall, inner ring and the bearing of dust-proof seal ring are fitted tightly, the rear end cap of described motor list shaft is provided with sealant.
According to another embodiment of the present utility model, further comprise, the diameter of the endoporus of described dust-proof seal ring is less than the external diameter of axle.
According to another embodiment of the present utility model, further comprise, described packing ring is wave washer or plain washer.
According to another embodiment of the present utility model, further comprise, described sealant is sealed paper or sealing plate.
According to another embodiment of the present utility model, further comprise, described axle 3 is the two shafts in single shaft or both sides.
The beneficial effects of the utility model are: this shaft has the stepping motor of dust reduction capability, conventional structure to existing stepping motor has carried out the design of dust waterproof construction, the shaft of stator and bearing place have designed very simply has the elasticity dust-proof seal ring, and the shaft and the bearing place that have changed conventional stepping motor do not fill containment member or the hermetically-sealed constructions such as oil sealing are housed.After having increased a kind of shaft and thering is the dust reduction capability sealing ring, reach the dust degree of protection that improves stepping motor, realized the dust reduction capability of stepping motor.
This shaft has the Step Motor Design advanced person of dust reduction capability, and exclusion seal is simple and reasonable, reliable, with low cost, the advantages such as good manufacturability.Can be generalized on the end cap of existing various stepping motors, the degree of protection of existing stepping motor is stepped to a new level.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
