Conventionally, this type of device was
There is one described in Publication No. 231031. FIG. 2 shows an example of an electromagnetic brake equipped with this conventional device, in which 1 is a yoke, 2 is a coil, 3 is a friction plate, 4 is an armature having a locking part 10, and 5 is a leaf spring. , 6 is a rivet, 7 is a locking member having a flange portion 9, 8 is an outer hub, 11 is an inner hub, 12
13 is a spline, 13 is a connecting member (such as a spring pin), 14 is a holding member, 15 is an elastic member (in this example, an O-ring), 16 is a plate, and 17 is a braked shaft. Note that G 1 indicates the opposing gap between the magnetic pole portion of the yoke 1 and the armature 4, and G 2 indicates the opposing gap between the flange portion 9 and the locking portion 10.

制動軸１７に制動がかけられる。 In this configuration, when the coil 2 is not energized, the armature 4 is separated from the magnetic pole part of the yoke 1, but when the coil 2 is energized by energization, the armature 4 receives an electromagnetic attraction force. It is attracted toward the magnetic pole part against the spring force of the release leaf spring 5, and the magnetic pole part and the friction plate 3 are brought into pressure contact, and braking is applied to the braked shaft 17.

プライン１２のバツクラツシユに起因するトルク
振動を吸収させるために設けてある。 In the electromagnetic attraction process of the armature 4, when the locking portion 10 of the armature 4 collides with the flange portion 9 of the locking member 7, if there is no wear on the friction surface of the armature 4 (in this case, G 1
= G 2 ), the armature 4 comes into pressure contact with the member facing it, but if wear occurs, a gap corresponding to the amount of wear exists between the armature 4 and the member facing it. The contact friction force of the connecting member 13 with respect to the holding member 14, in other words, the holding force of the holding member 14 with respect to the connecting member 13 is set to be lower than the electromagnetic attraction force in this amateur electromagnetic attraction process, so that the attraction continues. During the suction process of the armature 4, the outer hub 8 moves in the moving direction of the armature 4 together with the connecting member 13. Therefore, the engaging portion 13A of the connecting member 13 that engages with the holding member 14 is pulled out from the holding member 14 against the contact friction force between the connecting member 13 and the holding member 14. Since the return movement amount of the armature 4 when the brake is released is always constant and equal to the gap G1 , the gap between the armature 4 and the member facing it is adjusted to the original gap length. Elastic member 15
is provided to absorb torque vibration caused by backlash of the spline 12 between the inner and outer hubs 11 and 8 during braking.

As described above, this automatic gap adjustment device has a predetermined contact friction force (holding force) between the holding member 14 and the one end (engaging portion) 13A of the connecting member 13 that fits therein. The holding member 14 holds the engaging portion 13A of the connecting member 13, and when a force exceeding the predetermined holding force is applied to the connecting member 13, the force automatically moves the connecting member 13 to the armature 4 side. Therefore, it is important to have a predetermined holding force according to the design value as the above-mentioned holding force. There is a possibility that the mating surface of the member 14 may crack, and when this cracking phenomenon occurs, the desired holding force cannot be obtained, resulting in the need for reassembly or reassembly.

ルクの低下を招くといつた問題があつた。 Furthermore, in the case where the elastic member 15 is provided as in the conventional example, when the elastic member 15 absorbs the torque vibration caused by the backlash, the press-fitted portion of the engaging portion 13A of the holding member 14 and the connecting member 13 has a surface. Pressure vibration occurs, resulting in a phenomenon in which the engagement surfaces of the two are slightly worn (fretting phenomenon), and the above-mentioned holding force increases, leading to loss of air gap adjustment function and reduction in braking torque. It was hot.

的とする。 This idea was made to solve the above-mentioned conventional problem, and the holding force between the connecting member and the holding member into which one end is press-fitted may vary during initial assembly or change during operation. It is an object of the present invention to provide an automatic gap adjustment device for an electromagnetic coupling device that can improve reliability compared to conventional devices without causing problems.

In order to achieve the above object, this invention provides a holding member into which the connecting member is fitted, made of iron-based or copper-based oil-impregnated sintered metal.

This invention is based on the conventional automatic gap adjusting device shown in FIG. 2, in which the holding member 14 is made of an oil-impregnated sintered metal, particularly an iron-based or copper-based oil-impregnated sintered metal, as shown in FIG. This is a member 140. The other configurations are the same as those in FIG. 2 above.

上無くすことができ、組立時、常に所望の接触摩
擦力を確保することができる。 When the connecting member 13 is press-fitted, in the conventional case, the engaging portion 13A of the connecting member 13 gets caught on the fitting surface of the holding member 14, causing strain, but in this embodiment, the holding member 13 Since the member 140 is made of an oil-impregnated sintered metal that is softer than the connecting member 13, when it is press-fitted, the fitting surface exhibits a concave action to fit the maximum diameter portion of the engaging portion 13A, and also has a lubricating action. The above-mentioned squishing phenomenon can be virtually eliminated, and a desired contact friction force can always be ensured during assembly.

可能になる。 In addition, the connecting member 13 at the time of back crushing
The micro-vibration wear caused by surface pressure vibration between the holding member 140 and the holding member 140 is also sufficiently reduced due to the lubricating effect of the oil-impregnated holding member 140, thereby preventing the occurrence of a situation in which the air gap adjustment function is lost during operation. It becomes possible to do so.

As explained above, this device is made of oil-impregnated sintered metal and is made of oil-impregnated sintered metal, so that the holding member is fitted inside one hub and maintains a predetermined contact friction force between it and one end of the connecting member. Since it is possible to eliminate roughness and wear of the press-fitted part between the connecting member such as fretting and the above-mentioned holding member during operation and operation, it is possible to prevent the above-mentioned contact friction force from varying from the time of assembly or changing during operation. It is possible to significantly improve reliability compared to the conventional method.
