Description

technical field

[0001] The invention relates to a cooling structure in a magnetic powder brake, in particular to a water cooling structure for a magnetic powder brake. Background technique

[0002] Magnetic powder brake is a multi-purpose, high-performance automatic control element, widely used in locomotive start, simulated load, wire and cable, metallurgy, tablet press machine and other winding and tension control, the magnetic powder in the magnetic powder brake produces magnetic linkage under the action of the magnetic force , so that the output shaft and the input shaft rotate as a rigid body, and slip occurs during operation, and the slip causes part of the energy to be converted into heat. Generally, the temperature must be controlled below 75°C during operation. When the temperature exceeds this temperature, it will affect the magnetic powder. service life of the brake.

Examples

Embodiment Construction

[0021] Such as Figure 1 to Figure 4 As shown, a magnetic powder brake water cooling structure includes a rotor assembly 1 that can rotate around an axis and a cooling shaft 2 coaxially and detachably fixed on the rotor assembly 1 . In the present invention, the cooling shaft 2 refers to a piece of workpiece that is detachably connected to the rotor assembly and has friction with the water seal cover 3 . In the prior art, the integrated casting of the rotor assembly and the output shaft is difficult and costly. To ensure power transmission, the rotor assembly and the output shaft are generally forged separately and then welded together. This is obviously different from the design of the present invention which is provided with the cooling shaft 2 and detachably connected to the rotor assembly, and the cooling shaft 2 is generally also a part of the output shaft and cannot be confused with the output shaft.
