Abstract
The utility model relates to the stepping motor end cover technology field, and especially relates to a stepping motor end cover possessing the waterproof function. The stepping motor end cover includes an end cover, and the periphery of the end cover is provided with screw holes. The inside of each screw hole is provided with a recess. The edge of the recess is provided with an external stopping mouth. The stepping motor end cover possessing the waterproof function is advanced in design, simple, reasonable and reliable in protection and sealing structure, low in cost and excellent in usability, and can be applied to the end covers of various conventional stepping motors to improve the protection level of the conventional stepping motors.
Description
Technical field
The utility model relates to a kind of electric motor end cap, relates in particular to a kind of stepping motor end cap with water-proof function.
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, 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 abominable, open-air workplace, such as monitoring, The Cloud Terrace, underwater instrument 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 under adverse circumstances, use present stepping motor, often steam, corrosive gas can locate to enter motor internal by screw hole of motor etc., the part of motor internal is corroded, and motor rotor magnetic steel is oxidized, and motor performance descends, rotor is stuck, the insulating motor coil grade reduces, and causes coil inside to puncture or short circuit etc. situation, causes motor very short time to sustain damage, therefore equipment damage, and causes very big loss.
The degree of protection that how to improve stepping motor is a urgent problem.Some improve the method for the degree of protection of stepping motor, and such as outside motor covering protective casing, although can improve the degree of protection of motor, because electric machine structure is huge, expense increases, and this is not a kind of design of preferably cost performance.
Analyzed the structure of stepping motor end cap both domestic and external, found that most of water or steam are that the infiltration in other places can solve with corresponding seepage control measure at the screw place infiltration motor internal of the hold-down screw of stepping motor end cap basically.Therefore solve the stepping motor fixing screw hole water the infiltration problem and take more corresponding measures, the degree of protection of stepping motor can be improved greatly so, stepping motor is used among the rugged environment, such as chemical industry, field operation, underwater operation etc. occasion.
Summary of the invention
The technical problems to be solved in the utility model is: the problem that existing stepping motor fixing screw hole has water to infiltrate provides a kind of stepping motor end cap with water-proof function.
In order to overcome the defective that exists in the background technology, the utility model solves the technical scheme that its technical problem adopts and is: this stepping motor end cap with water-proof function comprises end cap, is provided with screw hole around the end cap, is provided with depression in the described screw hole; Described concave edges is provided with male half coupling.
According to another embodiment of the invention, further comprise and be provided with packing ring and O shape rubber seal in the described depression.
According to another embodiment of the invention, further comprise and place screw in the described screw hole, and screw compresses described packing ring and O shape rubber seal.
According to another embodiment of the invention, comprise that further described depression is bowl-shape.
The beneficial effects of the utility model are: this stepping motor end cover designs advanced person with water-proof function, exclusion seal is simple and reasonable, reliably, 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.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model end cap screw hole;
Wherein: 1, end cap, 2, screw, 3, packing ring, 4, O shape rubber seal, 5, depression, 6, male half coupling, 7, extraneous sepage, 8, the gap, 9, screw hole.
Embodiment
As depicted in figs. 1 and 2, comprise end cap 1 among the figure, be provided with screw hole 9 around the end cap 1, described screw hole 9 front ends are provided with depression 5,5 outsides of caving in are male half coupling 6, are provided with packing ring 3 and O shape rubber seal 4 in the depression 5, are provided with screw 2 in the screw hole 9, insert and fully tighten connection from packing ring 3, O shape rubber seal 4 with screw hole is connected, described O shape rubber seal 4 closely is connected with depression 5 inwalls.The installing hole design of stepping motor end cap has the depression 5 of high-protection level, male half coupling 6 is arranged on the limit, 5 in-built pads 3 and O type rubber seal 4 cave in, because the pressuring action of screw 2 makes the isolated outside motor of O type rubber seal and inside, thereby this stepping motor end cap is reached have water-proof function, the function of high-protection level.
Be provided with gap 8 between screw 2 and the end cap 1.
