Abstract
The utility model relates to technical field of motors, especially a kind of permanent magnetic brushless, including motor housing, motor housing inside are equipped with rotor and motor stator, and motor housing surface is equipped with elastic washer component.A kind of permanent magnetic brushless of the utility model, elastic washer component is installed in motor housing outer surface, it is fixed in a part of motor housing surface as motor, during the motor used, elastic washer component is in motor housing and between electric drilling match equipment, play the role of damping vibration when motor itself shakes, avoids the problem that motor shakes and then shakes loose components, extend the service life of motor and electric drilling match equipment.
Description
Technical field
The utility model relates to technical field of motors, especially a kind of permanent magnetic brushless.
Background technique
Vibration is all devices generally existing phenomenon in the process of running, and motor is operating as other equipment
Different degrees of vibration can occur in the process.Vibration is mainly manifested in the following aspects to the harm of motor: consumption energy,
Making the efficiency of motor reduces；Motor bearings is directly injured, accelerates the abrasion of motor bearings, the ordinary life of bearing is made to contract significantly
It is short；Rotor magnetic pole is loosened, causes stator and rotor mutually to wipe and touches, so as to cause rotor bending, fracture: (4) make motor
End wiring loosens, and causes End winding phase mutual friction, and insulation resistance reduces, and insulation life shortens, and insulation is caused to hit when serious
It wears；Make basis or be affected with the operating of the other equipment of electric drilling match, causes certain loose-parts, or even make some parts
It damages, causes the accident because of fatigue.
Utility model content
In order to overcome the shortcomings of existing motor shake outfit facility easy to damage and cause components loosen, the utility model
A kind of permanent magnetic brushless is provided, elastic washer component is installed in motor housing outer surface, is fixed in motor housing table
The a part of face as motor, during the motor used, elastic washer component is in motor housing and and electric drilling match
Between equipment, play the role of damping vibration when motor itself shakes.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of permanent magnetic brushless, including motor
Shell, motor housing internal-internal are fixed with motor stator, are connected with rotor by bearing inside motor housing, outside motor
Shell outer surface is fixed with elastic washer component.
Further, including elastic washer component is made of at least four elastic washers.
Further, the caulking groove for inlaying elastic washer is equipped with including motor housing surface.
Further, the quantity including caulking groove is consistent with the elastic washer quantity of gasket assembly.
The utility model has the beneficial effects that a kind of permanent magnetic brushless of the utility model, in motor housing outer surface
Elastic washer component is installed, a part of motor housing surface as motor is fixed in, during the motor used,
Elastic washer component is in motor housing and between electric drilling match equipment, plays the work of damping vibration when motor itself shakes
With, avoid the problem that motor shake so that shake loose components, extend the service life of motor and electric drilling match equipment.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of Fig. 1.
1. motor housing in figure, 2. motor stators, 3. rotors, 4. elastic washer components, 5. caulking grooves.
Specific embodiment
If Fig. 1 is the structural schematic diagram of the utility model, a kind of permanent magnetic brushless, including motor housing 1, motor housing
1 internal-internal is fixed with motor stator 2, is connected with rotor 3 by bearing inside motor housing 1, outside the motor housing 1
Surface is fixed with elastic washer component 4.
As illustrated in fig. 1 and 2, elastic washer component 4 is made of at least four elastic washers.1 surface of motor housing, which is equipped with, to be used
In the caulking groove 5 for inlaying elastic washer.The quantity of caulking groove 5 is consistent with the elastic washer quantity of gasket assembly 4.
In use, opening up at least four caulking grooves 5 on motor housing before this, fixed glue is applied in caulking groove 5, then by bullet
Property washer is embedded on caulking groove 5, and making it through fixed glue is fixed in the caulking groove 5 on 1 surface of motor housing, is fixed on outside motor
The eye on 1 surface of shell becomes blind a part of gasket assembly 4 as motor, and during the motor used, elastic washer component 4 is in
Motor housing and between electric drilling match equipment, plays the role of damping vibration when motor itself shakes, avoid motor shake into
And the problem of shaking loose components, extend the service life of motor and electric drilling match equipment.
It is described above to be merely exemplary for the utility model, and not restrictive, those of ordinary skill in the art
Understand, in the case where not departing from spirit and scope as defined in the appended claims, many modifications can be made, change or wait
Effect, but all will fall within the protection scope of the utility model.
