Description
The utility model relates to a kind of electromagnetic clutch power-off brake, especially a kind of electromagnetic clutch power-off brake that does not have slip ring.
Existing electromagnetic clutch power-off brake mostly has been the slip ring type, it is paid by flywheel, yoke, field coil, armature, spring, transmission shaft, braking and forms, yoke is fixedlyed connected with flywheel, the required power supply of field coil imports through brush and slip ring, armature is connected with spline housing with transmission shaft, finishes clutch and braking maneuver by spline housing moving on transmission shaft.In field coil when energising,, the yoke adhesive armature passes to transmission shaft with flywheel power, promotes the armature disconnecting clutch and presses to braking and pay by being fixed on some helical springs in the armature during outage, realizes cutting off main movement and deceleration loading.
The deficiency of this electromagnetic clutch power-off brake is:
1. because the slip ring structure is easy to generate the situation of electrical spark and brush bad connection, thereby can causes the clutch unstable properties, computer and instrument and meter for automation are produced the phenomenon of disturbing;
2. between spline housing and the transmission shaft sliding friction is arranged, cause adhesive, opening velocity slack-off;
3. owing to armature internal fixation helical spring, increased the volume and weight of armature, thereby influenced the sensitivity of clutch brake;
4. helical spring is owing to be subjected to axially, radially and the restriction of armature size, and its spring force is little, thereby influences braking ability;
5. owing to yoke and armature direct friction, field coil intensification, magnetic potential are reduced, thereby reduce the transmitting torque ability of clutch.
In view of above-mentioned, the purpose of this utility model just provides a kind of no slip ring type electromagnetic clutch power-off brake that overcomes above-mentioned deficiency.
For achieving the above object, the utility model is by the following technical solutions:
A kind of no slip ring type electromagnetic clutch power-off brake group, the yoke assembly, armature component, transmission shaft, the braking that comprise flywheel, be made of yoke and field coil are paid, the flywheel swivel bearing is on transmission shaft, yoke assembly, armature component, braking are paid order and are arranged in the flywheel inboard, it is characterized in that:
Folder is established rotor between yoke assembly and the armature component, and rotor and flywheel are fixed, and a relative side with armature component is equipped with friction plate on the rotor;
A yoke and a static fixed block are fixed, and are supported on the rotor through bearing;
Armature component is made of armature, petal dish spring, key cover, and the key cover is connected with transmission shaft, and the dish spring is connected with the key cover and embeds in the groove of armature.
Described rotor is a revolving part that axial cross section is a T shape mesopore, which is provided with the step that 3-6 is used for making groove that rotor uses by the fixing counter sink of bolt and described flywheel, the magnetic cut-off slot that prevents magnet short-cut path, installation friction plate and rigid bearing to use.
Described yoke is provided with installs the step that groove that field coil uses and rigid bearing are used.
Described dish spring is a 3-6 lobe shape belleville spring, has 3-6 to be used for making the dish spring to overlap the circular hole that is connected by bolt with described key on it.
The groove shapes of described armature is corresponding with the shape of dish spring, and the 0.5-2mm gap is arranged between the two.
Rotor is along with flywheel rotates.In field coil when energising,, rotor attracts armature, drives armature rotation by its friction plate, makes transmission shaft that armature connects along with rotor together rotates.Behind the coil blackout, armature is pressed to brake by the dish spring and is paid brake and transmission shaft.Armature does not contact with yoke in attracting process, has only the dish spring to produce axial deformation in the movement process of armature, and the key cover is maintained fixed motionless, does not have the friction that endwisely slips.
The utlity model has following advantage:
1. because yoke assembly adopts no slip ring structure, therefore avoid electrical spark that the slip ring structure produces and caused the clutch unstable properties because of the brush bad connection, and computer and instrument and meter for automation produced the phenomenon of disturbing, also exempted simultaneously the slip ring structure maintenance has been maintained;
2. because of not having friction between key cover and the transmission shaft, so accelerated the adhesive opening velocity of clutch brake;
3. owing to adopted petal dish spring, braking moment is big, so improved the braking ability and the speed of response of clutch brake;
4. after adopting the dish spring, can reduce the volume and weight of armature, so improved the sensitivity of clutch brake;
5. owing to adopt rotor, avoided the friction between armature and yoke, so reduced coil temperature rise.Make the performance of clutch brake more stable;
6. owing to have non-working-gap between rotor and the yoke, so behind the coil blackout, can make that magnetic field collapses sooner, dead electricity is braked rapider.
