Abstract
The utility model relates to the technical field of stepping motors, and especially relates to a stepping motor structure with a waterproof function. A front end cover is provided with an end cover screw hole, and a screw seal ring is disposed at the end cover screw hole. A rear end cover is provided with a no-through screw hole. A screw passes through the end cover screw hole and the no-through screw hole to be connected the front end cover, the rear end cover, and a stator. The joint of one side of the stator with the front end cover, and the joint of the other side of the stator with the rear end cover are respectively provided with an elastic seal ring. The outer side of the stator is coated with an epoxy-resin layer. The interior of the front end cover is provided with an elastic oil seal and a bearing. The rear end cover is provided with a waterproof cable connector. According to the utility model, a stepping motor is provided with the waterproof sealed structure, thereby preventing water from permeating into the motor from a motor fixed screw when the motor works underwater, achieving the purpose of improving the protection level of the motor, and enabling the motor to be capable of working in a severe environment or underwater.
Description
Technical field
The utility model relates to a kind of stepping motor, relates in particular to a kind of stepping motor structure 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, and use occasion is that requirement for environmental conditions is higher.Along with the development of applied science technology, the chemical industry that some environment for use conditions are more severe, outdoor workplace, as monitoring, The Cloud Terrace, underwater instrument etc. also needs to use 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 the screw hole of motor etc., the part of motor internal is corroded, motor rotor magnetic steel is oxidized, motor performance declines, rotor is stuck, 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 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 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 good cost performance.
The structure of stepping motor end cap both domestic and external, find that most of water or steam are the screw at the hold-down screw of stepping motor end cap substantially, gap between the stator punching of stator outer surface, axle and bearing contact-making surface, bearing chamber and bearing outside diameter contact-making surface and draw lead-out wire place infiltrate motor internal.Therefore solve stepping motor fixing screw hole water infiltration problem and take more corresponding measures, the degree of protection of stepping motor can be improved greatly so, can make stepping motor among rugged environment, 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 structure of stepping motor end cap both domestic and external, find that most of water or steam are the screw at the hold-down screw of stepping motor end cap substantially, gap between stator outer surface stator punching, axle and bearing contact-making surface, bearing chamber and bearing outside diameter contact-making surface and draw lead-out wire place infiltrate motor internal, a kind of stepping motor structure with water-proof function is provided.
In order to overcome the defect existing in background technology, the utility model solves the technical scheme that its technical problem adopts: this stepping motor structure with water-proof function comprises front end housing, rear end cap and stator, stator is placed between front end housing and rear end cap, be fixedly connected with by screw, described front end housing is provided with end cap screw hole, and place is provided with screw sealing ring at end cap screw hole, described rear end cap is provided with the screw hole not penetrating, screw is connected front end housing by end cap screw hole with the screw hole not penetrating, rear end cap and stator, one side of stator and front end housing junction, and opposite side and rear end cap junction are provided with elastic seal ring, the outer surface of described stator scribbles one deck epoxy resin, in described front end housing, be provided with elasticity oil sealing and bearing, elasticity oil sealing and bearing are placed in the both sides of axle, described rear end cap is provided with Waterproof cable joint, described axle is the two shafts in single shaft or both sides.
The beneficial effects of the utility model are: the utility model be at Step Motor Design hermetically-sealed construction that can waterproof, when motor is worked under water, can contact contact position, motor lead-out wire infiltration motor internal with end cap from outer surface, back end cover for motor screw hole, the motor stator of motor hold-down screw, Motor Shaft, stator by anti-sealing.Thereby reach the object that improves motor degree of protection, can make stepping motor under rugged environment or work under water.The utlity model has advanced design, the advantages such as exclusion seal is simple and reasonable, reliable, good manufacturability.
