Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, and specifically relates to an armature disc. Background Technology

[0002] The armature disc is a key component widely used in electromagnetic devices, typically in electromagnetic clutches, electromagnetic brakes, and electromagnetic brakes for articulated robots. Its main function is to connect or separate mechanical parts through electromagnetic force. Traditional armature discs have a relatively simple structure, usually consisting of an armature disc body and a central hole.

[0003] However, in practical applications, traditional armature discs have poor positioning effects during installation, which reduces the stability of the armature disc installation. The armature disc is prone to vibration and noise when running at high speed and frequently starting and stopping, which affects the stability and service life of the equipment and is not conducive to achieving good braking effect. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an armature disc that offers good positioning, stable installation, reduced vibration and noise, and stable operation.

[0005] The objective of this utility model can be achieved through the following technical solution: an armature disc, comprising an armature disc body, a central hole at the center of the armature disc body, a circular hole on the surface of the armature disc body, a circular groove on the surface of the armature disc body, a through hole on the inner wall of the circular groove, and a conical surface at the connection between the through hole and the circular groove. By providing the central hole, the armature disc body can be easily fitted onto a support shaft, facilitating its installation. The conical surface makes the connection between the circular groove and the through hole smoother. By providing the circular hole, circular groove, and through hole on the surface of the armature disc body, the point of application of electromagnetic force is effectively dispersed, reducing vibration and noise, and improving the operational stability of the equipment.

[0006] In the aforementioned armature disk, there are three circular holes and three through holes, arranged alternately. This alternating arrangement of the circular and through holes helps to distribute the electromagnetic force evenly, increases the heat dissipation area, improves heat dissipation efficiency, prevents overheating, and extends the service life of the armature disk body. Simultaneously, it allows the armature disk to distribute force more evenly when under load, reducing localized stress concentration and improving the load-bearing capacity of the armature disk.

[0007] In the armature disc, the inner wall of the circular groove is provided with a groove, the inner wall of the groove is fixedly connected with a spring, and the side, away from the inner wall of the groove, of the spring extends to the inner cavity of the circular groove and is fixedly connected with a gasket. Through the circular groove and the through hole, the armature disc body is conveniently fixed and installed. Through the groove, the spring and the gasket, the spring generates tension on the gasket, the gasket is in close contact with the bolt, the bolt is tensioned, the bolt is prevented from loosening during long-time use of the armature disc, and the stability and safety of the installation of the armature disc body are improved.

[0008] In the armature disc, the inner wall of the circular groove is provided with a groove, the inner wall of the groove is fixedly connected with a spring, and the side, away from the inner wall of the groove, of the spring extends to the inner cavity of the circular groove and is fixedly connected with a gasket. Through the circular groove and the through hole, the armature disc body is conveniently fixed and installed. Through the groove, the spring and the gasket, the spring generates tension on the gasket, the gasket is in close contact with the bolt, the bolt is tensioned, the bolt is prevented from loosening during long-time use of the armature disc, and the stability and safety of the installation of the armature disc body are improved.

[0009] In the armature disc, the inner wall of the circular groove is provided with a groove, the inner wall of the groove is fixedly connected with a spring, and the side, away from the inner wall of the groove, of the spring extends to the inner cavity of the circular groove and is fixedly connected with a gasket. Through the circular groove and the through hole, the armature disc body is conveniently fixed and installed. Through the groove, the spring and the gasket, the spring generates tension on the gasket, the gasket is in close contact with the bolt, the bolt is tensioned, the bolt is prevented from loosening during long-time use of the armature disc, and the stability and safety of the installation of the armature disc body are improved.
