本発明はシヨートストロークの電磁石を使用し
て電磁石と制動ばねを制動力の作用点上に位置す
るデイスク形電磁ブレーキに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a disc-type electromagnetic brake that uses short-stroke electromagnets to position the electromagnet and brake spring at the point of application of braking force.
従来のデイスク形電磁ブレーキは制動トルクが
比較的小さいブレーキに適用されており、制動ト
ルクが250Kg・ｍ以上になると電磁石が大きくな

高価格であるドラム形電磁ブレーキが使用されて
いる。 Conventional disc-type electromagnetic brakes are applied to brakes with relatively small braking torque, and when the braking torque exceeds 250 kg・m, the electromagnet becomes larger, so it is better for the electromagnet structure, installation method, and braking force operation mechanism. Therefore, drum-type electromagnetic brakes, which are more expensive than disk-type electromagnetic brakes, are used as brakes with large braking force.

欠点があつた。 Figure 1 shows a conventional disc-type electromagnetic brake, in which a disc-shaped disc 2 fixed to a motor shaft 1 is pressed against a brake pad 3a by the force of a brake spring inside a brake unit 3 to generate braking force. The brake unit 3 is attached to the frame 4 from the lateral direction. In such a structure, since the electromagnet must also be made larger to increase the braking force, the frame 4 has the disadvantage of protruding further in the lateral direction, resulting in a larger external shape.
本発明は上記欠点に鑑みなされたもので、横方
向へ突出しないようにして電磁石を大形化し制動

ことを目的とする。 The present invention was made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a disk-type electromagnetic brake in which the electromagnet is enlarged so as not to protrude laterally, and the braking force is increased.

る。 An embodiment of the present invention shown in the drawings will be described below. In Figures 2 and 3, motor shaft 1
The brake pads 3a of the brake unit 3 are attached to the brake springs 1 on both sides of the disc-shaped disc 2 that is fixed to the brake pads 3a of the brake unit 3.
Generates pressing braking force with the force of 2. One brake pad 3a is fixed to the armature 5, the other brake pad 3a is fixed to and faces a pad holder 6, and the pad holder 6 is slidably supported on the frame 4 by a protrusion 6a. Electromagnetic yoke 7
The coil 9 is slidably supported on the frame 4 by pins 8 at a position close to the disk 2, and the rod 5a planted in the center of the armature 5 is connected to the center of the yoke 7 via a non-magnetic collar 10. A brake spring 12 is installed between the collar 10 and a non-magnetic collar 11 that is engaged with the armature 5 and slides on the yoke 7. A guide pin 13 installed in the yoke 7 passes through the armature 5 and the pad holder 6 and is locked with an adjustment nut 14, and a spring 15 is installed between the armature 5 and the pad holder 6. The gap between the end of the rod 5a and the tip of an adjustment bolt 16 attached to the frame 4 is adjusted to 1/2 of the gap δ between the armature 5 and the yoke 7 that occurs when the coil 9 is demagnetized. A spring 17 biases the yoke 7 in a direction opposite to the disk 2.

同様にデイスク２を押しつけて制動を行う。 Next, the action will be explained. When braking, when the electromagnetic coil 9 is demagnetized, the armature 5 is separated from the yoke 7 by the braking spring 12, and the force on the yoke 7 side is transmitted to the guide pin 13, adjustment nut 14, pad holder 6, and brake pad 3a. The force on the armature 5 side is transmitted to the armature 5 and the brake pad 3a to similarly press the disc 2 and perform braking.

キパツト３ａとの間隙をバランスよく保つ。 To release the brake, when the electromagnetic coil 9 is excited, an attractive force is generated in the space between the yoke 7 and the armature 5, and when the attractive force becomes larger than the brake spring 12, the yoke 7 and the armature 5 are attracted to each other. For armature 5, rod 5a is adjustment bolt 1
After the contact, the yoke 7 moves the rest of the way and the brake pad 3a separates from the disc 2, releasing the brake. The spring 17 allows smooth movement of the yoke 7, and the spring 15 maintains a well-balanced gap between the disc 2 and the brake pad 3a.

効果がある。 As described above, according to the present invention, in a disc type electromagnetic brake, the armature that fixes the brake pad by attracting the armature to the electromagnet comes into contact with the adjustment bolt in half of the stroke and stops, and after that the electromagnet does not move. The pad holder that fixes the brake pads is interlocked so that the brake pads are released at the same gap on both sides of the disc, so the brake pads receive the braking force at the center and the functions of transmitting the force and receiving the braking force are divided into two. By doing so, wear on the mechanical parts is reduced and the movement of the brake pad is smooth, and by locating the guide pin that supports the electromagnet below the electromagnet, the lateral protrusion is reduced and the overall size is reduced. It has excellent effects such as being easily adaptable to larger electromagnets.
