Description
Technical field
The present invention relates to a kind of Electromgnetic seat brakes, especially a kind of to prevent right angle setting from generating harmful friction
Self-balancing brake.
Background technique
Spring pressurization Electromgnetic seat brake is one of numerous type brakes.Since its is small in size, braking moment
Greatly, and installation and debugging are convenient, are widely used in the multiple fields such as lifting equipment, harbour, metallurgy, battery truck, wind-power electricity generation.But
It is this brake since rotor is in free state in the released state, a rotor left side can inevitably occurs in motor rotation
Right swing simultaneously mutually rubs with friction pair face and generates noise, and this problem is particularly acute in the vertical installation of motor, because vertical
The motor of installation, under release conditions, brake rotor is in contact by gravity with flange, when motor rotates, can generate friction
And noise, upshift brakes abrasion improve brake temperature rise, reduce brake service life.
Summary of the invention
The present invention is technical problem present in solution well-known technique and providing one kind can prevent right angle setting from having
The self-balancing brake of evil friction.
The technical scheme adopted by the present invention to solve the technical problems existing in the known art is that one kind can prevent from hanging down
Straight installation generates the self-balancing brake of harmful friction, including the flange, rotor, armature set gradually from the near to the distant apart from motor
And stator, it is embedded with coil and tripping spring on the end face of the armature in the stator, is connected in the rotor
Axle sleeve, the axle sleeve are equipped with the undergauge projecting ends protruded into inside the flange, cover on the undergauge projecting ends of the axle sleeve
Equipped with support spring, in the support spring, the support spring is clamped in the rotor and support portion the rotor supports
Between part, the support member anchor ear is on the undergauge projecting ends of the axle sleeve.
The support spring is wave spring.
The support member is circlip.
The armature is connect using hollow screwed pipe with the stator.
The brake uses the screw across the stator, the hollow screwed pipe and the flange to be packed in motor end face
On.
Friction plate is equipped on two end faces of the rotor.
The advantages and positive effects of the present invention are: rotor is adopted in the state that rotor is released using support spring
It is jacked up with support spring, rotor is made to keep the state disengaged with flange, and then avoid generating friction under rotation status therebetween
And noise, extend brake service life.And it by using anchor ear support member and support spring composite structure, can be realized
Autobalance disengages rotor with flange always in a free state, and keeping gap is the half of brake clearance.The present invention
Using extremely low cost, solves the problems, such as that the vertical application abrasion of brake, noise and temperature increase, greatly improve vertical
The service life of formula application brake.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
In figure: 1, stator, 2, coil, 3, armature, 4, hollow screwed pipe, 5, rotor, 6, screw, 7, axle sleeve, 8, tripping spring,
9, support spring, 10, support member, 11, flange, 12, motor end face.
Specific embodiment
In order to further understand the content, features and effects of the present invention, the following examples are hereby given, and cooperate attached drawing
Detailed description are as follows:
Referring to Fig. 1, a kind of self-balancing brake that can prevent right angle setting from generating harmful friction, including apart from motor
Flange 11, rotor 5, armature 3 and the stator 1 set gradually from the near to the distant, in the stator 1 on the end face of the armature 3
Embedded with coil 2 and tripping spring 8, axle sleeve 7 is connected in the rotor 5, the axle sleeve 7 is equipped with and protrudes into the flange 11
The undergauge projecting ends in portion, are set with support spring 9 on the undergauge projecting ends of the axle sleeve 7, and the rotor 5 is supported on institute
It states in support spring 9, the support spring 9 clamps 10 anchor ear of support member between the rotor 5 and support member 10
On the undergauge projecting ends of the axle sleeve 7.
In the present embodiment, the support spring 9 is wave spring, can also use other springs, such as opening disc spring or tower
Spring etc..The support member 10 is circlip, and for circlip anchor ear on the undergauge projecting ends of the axle sleeve 7, the two relies on frictional force
It forms a fixed connection, is used to support the support spring 9, easy for installation, reliable performance.In the present embodiment, the armature 3 is adopted
It is connect with hollow screwed pipe 4 with the stator 1.The brake is used across the stator 1, the hollow screwed pipe 4 and the flange
11 screw 6 is packed on motor end face 12, reliable and stable.It is equipped with friction plate on two end faces of the rotor 5, can be increased
Strong braking effect.
The working principle of the invention:
When brake, coil 2 is powered off, and armature 3 presses to flange 11 under the action of tripping spring 8, by rotor 5,
And it is deformed wave spring 9, pressure of the rotor 5 by flange 11 and armature 3 generates braking moment, leaves the motor off rotation；When
When brake discharges, coil 2 is powered, and stator 1 overcomes the thrust of tripping spring 8 that armature 3 is attracted to be detached from rotor 5, and rotor 5 is released
It can be rotated with motor.Wave spring 9 restPoses at this time, and jacks up rotor 5, disengages it from flange 11, and gap is brake
The half in gap.
The present invention supports rotor 5 using wave spring 9, overcomes the gravity of rotor 5, rotor 5 is jacked up, and jacking up distance is brake
The half of nominal clearance.Fixed wave spring 9 is supported using axis circlip 10, the coupling mechanism force of circlip 10 needs to be greater than rotor gravity, but
Less than the elastic force of tripping spring 8.When the brake is released, since 10 coupling mechanism force of circlip is greater than the gravity of rotor 5, rotor 5
It cannot move down, while rotor 5 disengages with flange 11 under the action of wave spring screen resilience, prevents rotor 5 from contacting with flange 11
Generate harmful friction and noise.When brake after a period of use, rotor 5 is worn, and brake clearance becomes larger, and when braking, is turned
The displacement of son becomes larger, and the deformation of support spring 9 becomes larger, and support spring 9 pushes circlip 10 to move down, and brake reaches new equilibrium-like
State, therefore the present invention can be realized autobalance, disengage rotor with flange always in a free state, and keeping gap is system
The half in dynamic device gap.
Although the preferred embodiment of the present invention is described above in conjunction with attached drawing, the invention is not limited to upper
The specific embodiment stated, the above mentioned embodiment is only schematical, be not it is restrictive, this field it is common
Technical staff under the inspiration of the present invention, in the case where not departing from present inventive concept and scope of the claimed protection, goes back
Many forms can be made, within these are all belonged to the scope of protection of the present invention.
