Abstract
A novel electrical eddy current brake relates to the electrical eddy current brake technical field. An end cover (2) is arranged on a base (1). The central part of the end cover (2) is provided with an excitation coil (5). A rotor (3) is arranged on the central part of the excitation coil (5). A left armature body (4) and a right armature body (6) are symmetrically arranged above the excitation coil (5). The outer wall center of the end cover (2) is provided with a bearing cap (7). A water inlet (8) is arranged on the left armature body (4). A water outlet (9) is arranged on the right armature body (6). The novel electrical eddy current brake with a simple structure is convenient to operate. A magnetic field generated by an eddy current and an original air-gap magnetic field generate braking torque. The energy using cost is lowered. Furthermore, the novel electrical eddy current brake has great braking effects.
Description
Technical field:
The utility model relates to electric eddy current brake technical field, is specifically related to a kind of Novel electric eddy-current brake.
Background technology:
Brake is exactly brake appts.The machine components that make the movement parts in machinery stop or slowing down.Be commonly called as brake, lock.Brake is mainly made up of brake bracket, brake component and operating device etc.Some brake is also equipped with the automatic regulating apparatus in brake component gap.In order to reduce braking moment and physical dimension, brake is contained on the high speed shaft of equipment conventionally, but the main equipment higher to security requirement (as mine hoist, elevator etc.) should be contained near on the slow-speed shaft of equipment working portion.
Existing electric eddy current brake complex structure, complex operation, and braking effect is general, and the energy cost that braking consumes is high.
Utility model content:
The purpose of this utility model is to provide a kind of Novel electric eddy-current brake, and it is simple in structure, easy to operate, and magnetic field and former air-gap field that eddy current produces have produced braking moment, have reduced energy use cost, and its good braking effect.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises base, end cap, rotor, left armature body, magnet exciting coil, right armature body, bearing cap, water inlet, delivery port; End cap is arranged on base, in the middle of end cap, is provided with magnet exciting coil, and the centre of magnet exciting coil is provided with rotor, the top of magnet exciting coil is arranged with left armature body and right armature body, the center of end cap outer wall is provided with bearing cap, and left armature body is provided with water inlet, and right armature body is provided with delivery port.
The utility model operation principle: in the time being connected with direct current with the magnet exciting coil of rotor coaxial assembling, the magnetic flux that device produces forms magnetic closed-loop path through armature body, ring of eddy, air gap and rotor, because rotor outer ring face is braked into equally distributed tooth and groove, therefore the magnetic field that produces density interphase at an air gap ring of eddy inner surface, therefore, in the time that rotor is dragged rotation, producing alternation in the magnetic field of any point of ring of eddy inner surface changes, induce thus " eddy current ", the magnetic field that " eddy current " forms again with former air gap magnetic field interaction, on rotor, just produce braking moment, the power of engine output is converted to the equivalent caloric value that " eddy current " on ring of eddy produces, this heat is taken away by entering continual cooling water in ring of eddy bosh.
The utlity model has following beneficial effect: it is simple in structure, easy to operate, magnetic field and former air-gap field that eddy current produces have produced braking moment, have reduced energy use cost, and its good braking effect.
Brief description of the drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the right view of Fig. 1.
Embodiment:
Referring to Fig. 1 and Fig. 2, this embodiment by the following technical solutions: it comprises base 1, end cap 2, rotor 3, left armature body 4, magnet exciting coil 5, right armature body 6, bearing cap 7, water inlet 8, delivery port 9; End cap 2 is arranged on base 1, in the middle of end cap 2, be provided with magnet exciting coil 5, the centre of magnet exciting coil 5 is provided with rotor 3, the top of magnet exciting coil 5 is arranged with left armature body 4 and right armature body 6, the center of end cap 2 outer walls is provided with bearing cap 7, left armature body 4 is provided with water inlet 8, and right armature body 6 is provided with delivery port 9.
This embodiment operation principle: in the time being connected with direct current with the magnet exciting coil of rotor coaxial assembling, the magnetic flux that device produces forms magnetic closed-loop path through armature body, ring of eddy, air gap and rotor, because rotor outer ring face is braked into equally distributed tooth and groove, therefore the magnetic field that produces density interphase at an air gap ring of eddy inner surface, therefore, in the time that rotor is dragged rotation, producing alternation in the magnetic field of any point of ring of eddy inner surface changes, induce thus " eddy current ", the magnetic field that " eddy current " forms again with former air gap magnetic field interaction, on rotor, just produce braking moment, the power of engine output is converted to the equivalent caloric value that " eddy current " on ring of eddy produces, this heat is taken away by entering continual cooling water in ring of eddy bosh.
This embodiment has following beneficial effect: it is simple in structure, easy to operate, and magnetic field and former air-gap field that eddy current produces have produced braking moment, have reduced energy use cost, and its good braking effect.
