Description

Electromagnetic brake

Technical Field

The utility model belongs to the technical field of brakes, and particularly relates to an electromagnetic brake.

Background

The electromagnetic brake is a connector for transmitting the torque force of the driving side to the driven side, can be freely combined, separated or braked according to requirements, and has the advantages of compact structure, simplicity in operation, sensitivity in response, long service life, reliability in use, easiness in realizing remote control and the like.

The electromagnetic brake is an ideal automatic actuating element in modern industry, and mainly plays roles of transmitting power, controlling movement and the like in a mechanical transmission system.

The power-off brake in the electromagnetic brake brakes through the change of a magnetic field, the overall effect is poor, the friction is large, and partial magnetic force needs to be reserved to reduce the friction.

Detailed Description

In order to facilitate an understanding of the utility model, the utility model will now be described more fully hereinafter with reference to the accompanying drawings, in which several embodiments of the utility model are shown, but which may be embodied in many different forms and are not limited to the embodiments described herein, but rather are provided for the purpose of providing a more thorough disclosure of the utility model.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present; when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present; the terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs; the terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model; as used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Example 1

Referring to fig. 1 to 3, the electromagnetic brake of the present embodiment includes a brake body 100, a plurality of connection holes 110 are formed in a back surface of the brake body 100, a magnetic plate 120 is attached to the back surface of the brake body 100, and the magnetic plate 120 is fixed to the connection holes 110 by bolts.

The plurality of connecting holes 110 of the present embodiment are three connecting holes 110, and the three connecting holes 110 are arranged in an equiangular array, and the designed structure keeps the stability of the magnetic plate 120 in high-speed rotation.

The brake body 100 of the present embodiment is a power-off brake.

The back of the brake body 100 of the embodiment is provided with a plurality of circles of shallow grooves 130, the magnetic plate 120 is provided with a notch 140, and the notch 140 is along the radial direction of the shallow grooves 130, so that the design reduces the contact area between the magnetic plate 120 and the brake body 100, and reduces heat conduction.

The slot 140 of the present embodiment passes through the center of the magnetic plate 120, and the slot 140 is matched with the shallow slot 130 to realize the internal air circulation and take away the heat generated by the rotation of the brake body 100.

The above-mentioned embodiments only express a certain implementation mode of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention; it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several variations and modifications can be made, which are within the protection scope of the present invention; therefore, the protection scope of the present patent shall be subject to the appended claims.
