Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic brakes, in particular to an electromagnetic brake housing. Background Art

[0002] Usually, the magnetic shell of the electromagnetic brake needs to have magnetic conductivity. The conventional material is usually cast iron or carbon steel. Its main feature is that after the coil placed inside the magnetic shell is energized, the magnetic shell will be magnetized to generate a stable electromagnetic force. However, with the development of the industry, the performance requirements of the magnetic shell are getting higher and higher. It is difficult to rely solely on forging and machining, and it is easy to have holes, perforations, and shape and position tolerances that do not meet the requirements. In addition, various materials of traditional steel are uniform and consistent, and hardness, density, electromagnetic properties and other parameters cannot be adjusted on a large scale according to actual applications to meet the electromagnetic performance requirements of the electromagnetic brake. Therefore, a new electromagnetic brake shell has become an urgent problem that technicians in this field need to solve. Utility Model Content

[0021] The housing 1 is a powder metallurgy integral forming structure.

[0022] It should be noted that in the present application, the housing 1 is a regular hexagonal prism, and the interior of the housing 1 is a pore passage opened in sequence. A stable hole 12 is directly opened at one end of the housing 1 to set a connecting fixing key 6, and the housing 1 is connected to an external device through the connecting fixing key 6 to keep the housing 1 stable. Moreover, the outer side of the housing 1 has six sides of a regular hexagonal prism. During the braking process, the six sides form a strengthening structure to keep the housing 1 stable, so that the housing 1 of the electromagnetic brake can brake a rotating shaft 11 rotating at a higher speed.
