Abstract
The utility model provides a magnetic field isolation device of an electromagnetic power-off brake, which is arranged at the rear end of a whole magnetic pole and is a magnetic isolation ring. The magnetic isolation ring is arranged at the rear end of the whole magnetic pole, a high magnetic field generated by the magnetic isolation ring to the whole magnetic pole is utilized to perform effective isolation and shielding, and normal running work of an additionally installed shaft end encoder can be guaranteed. The magnetic field isolation device of the electromagnetic power-off brake is compact in structure in the axial dimension and is arranged reasonably and practically.
Description
Technical field
The utility model relates to the structure field of electromagnetism power-off brake, is specifically related to a kind of magnetic field isolation mounting of electromagnetism power-off brake.
Background technique
The electromagnetism power-off brake is that a kind of energising breaks away from (release); The frictin braek of spring to break braking; It has compact structure, easy for installation, wide adaptability, noise is low, frequency of okperation is high, be active in one's movements, brake advantages such as reliable, is a kind of desirable automation executive component.Along with the raising gradually of mechanical automation degree, need in the electromagnetism power-off brake, install the axle head encoder additional, be used for the rotating speed of measurement mechanical.But common electromagnetism power-off brake is after energising, and its field structure part promptly constitutes magnetic, has disturbed the magnetic field of encoder, causes the encoder can't proper functioning.
The model utility content
To the problem that exists in the above existing technology, the utility model provides a kind of electromagnetism power-off brake magnetic field isolation mounting that can guarantee newly-increased axle head encoder stable operation.
The utility model is realized through following technological scheme:
The magnetic field isolation mounting of electromagnetism power-off brake is arranged at whole trailing pole-tip, and said magnetic field isolation mounting is a magnetism resistent ring.
Said magnetism resistent ring is a ly12 aluminum alloy circle.
The beneficial effect of the utility model is: in whole trailing pole-tip magnetism resistent ring is set, the high magnetic fields that utilizes magnetism resistent ring that whole magnetic pole is formed is effectively isolated and is shielded, and can guarantee the axle head encoder normal operation work of installing additional.The utility model is compact structure on axial dimension, is provided with reasonable and practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 is whole magnetic pole; 2 is magnetism resistent ring.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is explained further details.
The utility model provides a kind of magnetic field isolation mounting of electromagnetism power-off brake, is to be provided with to whole magnetic pole 1 formed high magnetic fields, so the utility model employing magnetism resistent ring 2, is placed in whole magnetic pole 1 rear end as the magnetic field isolation mounting.Magnetism resistent ring more than 2 adopts ly12 aluminum alloy circle.
The utility model is provided with magnetism resistent ring 2 in whole magnetic pole 1 rear end, and the high magnetic fields that utilizes 2 pairs of whole magnetic poles 1 of magnetism resistent ring to form is effectively isolated and shielded, and can guarantee the axle head encoder normal operation work of installing additional.The utility model is compact structure on axial dimension, is provided with reasonable and practical.
Claims (2)
