Abstract
The invention discloses an electric brush assembling method for a brush motor. After an electric brush (3) is pre-pressed into a brush box (4), a torsional spring (2) is in failure, so that a rotor (5) can be mounted in a brush frame ring (1) quite conveniently; after the rotor (5) is mounted, the electric brush (3) is shifted slightly, and the torsional spring (2) can enable the electric brush (3) to pop up to enter a working state; a groove is formed in a contact part between the electric brush (3) and the torsional spring (2); the torsional spring (2) is directly clamped in the electric brush (3) to prevent from separating out; a matching structure of the electric brush and a spring comprises the brush frame ring (1), the torsional spring (2), the electric brush (3) and the brush box (4), wherein the torsional spring (2) is assembled on one side of the brush box (4); openings, including an opening in the upper side and openings in two sides, are formed in the three sides of the brush box (4); the torsional spring (2) is fixed by the brush frame ring (1); a torsional arm, which props against the brush frame ring (1), of the torsional spring (2) is made into a bending shape; a groove is formed in the back side of the electric brush (3); and the torsional arm of the torsional spring (2) is pressed into the electric brush (3).
Description
Technical field
The present invention relates to the fit structure of the brush assembly method and its brush of a kind of brush motor and spring, the structure can
Suitable for all brushed DC small machines.
Background technology
The brush assembling structure adopted by existing brush motor is pressurizeed using compression spring, and compression spring produces pressure for flexible
Power, therefore motor brush rocker ring must leave sufficient space and make its work, increased brush carrier ring external diameter so that motor entire outer diameter
Increase, and compression spring freely stretches in the case where pressurizeing without external force and can interfere rotor, cause assembling inconvenience.Install
Brush applying power need to be first given during rotor so as to rotor is reinstalled in indentation brush box, brush is decontroled afterwards, spring is freely ejected,
Whole process flow process is complicated, affects efficiency of assembling.
The content of the invention
It is an object of the invention to provide the cooperation of the brush assembly method and its brush of a kind of brush motor and spring is tied
Structure, the method and structure overcome disadvantages mentioned above, the outward appearance to product, are redesigned in terms of reliability, i.e., attractive in appearance, and
It is reliable, that is, assemble flow is simplified, installation time is saved again.
The purpose of the present invention and solve its technical problem underlying and employ the following technical solutions to realize：One kind has brush electricity
The brush assembly method of machine, after in advance be pressed into brush in brush box, rotor so very easily can be filled by torque spring failure
Enter in brush carrier ring, rotor gently dials brush after installing, and brush can be ejected by torque spring so as to enter working condition；Brush with
Torque spring contact portion has individual groove, torque spring that abjection is prevented in directly snapping in brush.
The fit structure of brush and spring in a kind of brush assembly method of above-mentioned brush motor, including brush carrier ring,
Torque spring, brush and brush box, torque spring are assemblied in brush box side, and three side of brush box is open respectively, upper opening and both sides
Opening；Torque spring is fixed by brush carrier ring itself, torque spring support the torque arm of brush carrier ring make it is curved；It is provided with recessed on rear side of brush
Groove, torque spring torque arm press-in brush.
During use, after in advance be pressed into brush in brush box, rotor so very easily can be loaded by torque spring failure
In brush carrier ring, rotor gently dials brush after installing, and brush can be ejected by torque spring so as to enter working condition；Brush and torsion
Power spring contact portion has individual groove, torque spring that abjection is prevented in directly snapping in brush.
The present invention has clear advantage and beneficial effect compared with prior art.From above technical scheme, this
It is bright to have the characteristics that：
1st, for outward appearance, pressurizeed using torque spring, torque spring is located at brush side, torque spring is solid by brush carrier ring itself
It is fixed, do not increase volume, effectively utilizes space structure reduces the external diameter of brush carrier ring, elegant in appearance, more reasonable utilization space.
2nd, for reliability, increase notch on rear side of brush, by designing torque spring torque arm so as to which rationally press-in is electric
Brush, can also make torque spring fail when brush is completely forced into brush box, by this point, can be before assembling rotor in advance by electricity
Brush is pressed in brush box, makes rotor be directly loadable into motor, gently brush can be made it into working condition for one group afterwards, effectively letter
Change assemble flow.
3rd, in working order under provide pressure by torque spring, wherein three side of brush box is open respectively, upper opening be in order to
Brush shunt welding is facilitated to move freely, the opening of both sides is to prevent from interfering with torque spring.Torque spring supports the torsion of brush carrier ring
Arm make it is curved, be conducive to assembling, it is also possible to prevent torque arm abjection and cause spring failure.
4th, rotor loads the process of brush carrier ring, and after in advance be pressed into brush in brush box, torsionspring failure so can be very
It is convenient to load rotor in brush carrier ring, assemble flow is simplified, installation time is saved, rotor is gently dialled brush after installing, is reversed
Brush can be ejected by spring so as to enter working condition.
5th, brush and torsionspring contact portion have individual groove, torsionspring that abjection is prevented in directly snapping in brush.
