Abstract
The utility model relates to a sealing structure of an alternating current signal electric motor with a brush. The fully sealing structure of the electric motor consists of a dynamic seal and a static seal. The dynamic seal consists of an H-shaped framework, an outer O-shaped sealing ring and an inner O-shaped sealing ring. The outer O-shaped sealing ring is arranged in an outer socket of the H-shaped framework, clinging to an inner hole of a stator so as to prevent the salty fog and humidity from entering into the electric motor through the inner hole of the stator. The inner O-shaped sealing ring is arranged in the inner socket of the H-shaped framework, clinging to an extended axis of the electric motor so as to prevent the salty fog and humidity from entering into the electric motor through the extended axis; and the static sealing ring consists of a patching board, a mulch, two sealing rings and a fastening screw. Two pieces of sealing rings are arranged on the two sides of the patching board respectively and behind the fastening screw, generating a sealing space between the housing end and the mulch. A brush and a slip ring are positioned in the space, insulating from the environment and preventing salty fog and humidity from entering into the electric motor. Therefore, the utility model solves the problem of the corrosion of the brush, the slip ring and the iron core and the short circuit between the rotor windings so as to enhance the reliability of the electric motor, being adequate for the maritime and outdoor environments.
Description
Technical field
The utility model relates to motor, refers to a kind of motor seal structure especially.
Background technology
Control synchro transmitter and control type synchro transformer etc. have brush AC signal motor, are the important control elements of servo system, often need to use with under the environmental condition in salt fog, moist sea.Because problems such as threephase stator winding interturn short-circuit, iron core corrosion, lug plate, terminal screw, brush and slip ring corrosion come off often appear in the long term of severe environmental conditions, motor, have had a strong impact on the use of whole equipment.So the problem that is in use run at motor and the sea of exposure must provide solution with the particularity of condition.Therefore, keeping under the constant substantially prerequisite of motor overall dimension, the utility model has provided a kind of all-sealed structure, stops salt fog, moisture enters motor internal, fundamentally solves the problem that bring to motor with environmental condition in abominable sea.
Summary of the invention
The utility model proposes a kind of control synchro or transformer of all-sealed structure,, can strengthen the resistance to corrosion of motor effectively, reduce the damage rate of motor owing to the all-sealed structure of motor.The motor of all-sealed structure, not only can be in the sea with using for a long time under the environmental condition, even environment uses for a long time in the open, thereby has widened the scope of application that brush AC signal motor is arranged greatly.
For reaching above-mentioned purpose, the utility model is made up of at the static seal of motor leading-out terminal the movable sealing and the design of design in the motor through hole.Described movable sealing is made up of three parts, is respectively H shape stainless steel insert, outer O-ring seals and interior O-ring seals.Outer O-ring seals is installed on the H skeleton in the outer groove, is close to stator inner hole, stops salt fog and moisture to enter in the motor from stator inner hole.Interior O-ring seals is installed in the H skeleton inner groovy, is close to the motor shaft extension, stops salt fog and moisture to enter in the motor from shaft extension; Described static seal is made of the terminal block that brush is housed, stainless steel protecting cover, the annular seal ring that has some holes and stainless steel trip bolt respectively.Two rings shape sealing ring places the both sides of terminal block respectively, after tightening trip bolt, between casing end face and protecting cover, just form a sealed space, this space is placed with brush and collector ring, because this space is hedged off from the outer world, salt fog and moisture all are difficult to enter, and have also just solved the etching problem of brush and slip ring.
Therefore superior effect of the present utility model is: the motor of all-sealed structure, its hermetically-sealed construction can effectively reduce problems such as motor threephase stator winding interturn short-circuit, iron core corrosion, can use in environment and open-air atmosphere in the sea.Strengthen the reliability of motor greatly, widened the scope of application of AC signal motor.
