Vertical magnetic powder brake

Abstract

The invention provides a vertical type magnetic powder brake, relating to the field of an electromechanical brake. The vertical type magnetic powder brake comprises a rotor, an upper magnetic pole and a lower magnetic pole, wherein the rotor comprises a rotor shaft and a rotor body for the coaxial fixation of the rotor shaft; the rotor body is in the shape of an annular stage provided with a high level part, a low level part and a settlement transition zone; the upper magnetic pole and the lower magnetic pole are sheathed on the rotor shaft; a first cavity and a second cavity exist between the upper magnetic pole and the lower magnetic pole; the internal shape of the first cavity is arranged in a manner of corresponding to the shape of the rotor body; the rotor body is located in the first cavity; magnetic powder is arranged in gaps between the first cavity and the rotor body; the second cavity is an annular cavity located on the outer side of the first cavity; and exciting coils are arranged in the second cavity. The vertical type magnetic powder brake is scientific and simple in structure, so that the magnetic powder can not easily enter a bearing; additionally, the vertical type magnetic powder brake can be installed in the vertical direction; and moreover, the service life of the vertical type magnetic powder brake is prolonged.

Description

technical field [0001] The invention relates to the field of electromechanical brakes, in particular to a magnetic powder brake. Background technique [0002] In the current commonly used magnetic powder brakes, the magnetic powder working chamber and the rotor are on the same parallel plane in terms of structural design, so they can only be installed horizontally. If vertical installation is required, the magnetic powder will fall into the side of the magnetic powder working chamber. , and it is easy to enter the rotating shaft, the torque performance is poor, and the magnetic powder brake is easy to be damaged. Contents of the invention [0003] The object of the present invention is to provide a magnetic powder brake that solves one or more of the above-mentioned problems in the prior art. [0004] The invention provides a vertical magnetic powder brake, comprising: a rotor, including a rotor shaft and an annular boss-shaped rotor body coaxially fixed to the rotor shaf...
