Hollow Shaft Magnetic Powder Clutch Reverse Input Method

Hollow shaft magnetic powder clutch housing rotary type, including front cover, front cover bushing, rotating drum, rear cover, left side retaining ring of drum, front cover retaining ring, right side baffle retaining ring of drum, dustproof retaining ring The front cover, the front cover sleeve and the rear cover form a drum cavity, and the drum cavity is internally connected with the rotating drum, and the left end surface of the rotating drum has a left retaining ring of the rotating drum, and the left retaining ring of the rotating drum The rotating drum is integrally formed, the circumferential surface of the rotating drum has a plurality of tension grooves, the central portion of the rotating drum is welded with stainless steel, and the right side of the rotating drum is connected with the right side of the rotating drum, and the rotating drum The right side baffle retaining ring has a groove inside, the groove is connected to the inner wool felt sealing ring, the front cover bushing is internally connected with the left outer bearing, and the left outer bearing is connected with the bearing spacer on the right side, the bearing is separated The left inner bearing is connected to the right side of the sleeve, and the dustproof retaining ring is connected to the right side of the left inner bearing.

Low-speed use of optimized hollow shaft magnetic powder clutch reversible input method:
Use the output end (or input end) of the connected magnetic powder clutch to connect the reel, and connect the gear motor or the like at the input end (or output end) and keep it in the opposite direction of rotation of the reel. This ensures a sufficient slip speed for stable torque control. As for the clutch input end and the output end mounting direction, the high speed end is usually connected to the clutch input end. That is to say, when the line speed is slow and the reel speed is low, the input end of the clutch is connected to the motor. The unwinding start diameter is large, and the short rotation at the beginning of the unwinding is slower. When sufficient slip speed is obtained in most of the running time, the output end is connected to the motor.

For the selection of the hollow shaft magnetic powder clutch coupling, the elastic coupling for connecting the load shaft, use a lower coupling such as a chain coupling. (When a highly flexible coupling such as a rubber coupling is used, there is a phenomenon in which the gap transmits torque, resulting in torque inconsistency.) At the same time, increase the rigidity of each part of the machine.



Principle and scope of hollow shaft magnetic powder clutch

Note on the use of hollow shaft magnetic powder clutch:
1. When the relative rotational speed is continuously in a high state, the life expectancy is reduced, so when setting, efforts should be made to reduce the relative rotational speed;
2, please pay attention to warm air: If the magnetic powder is damp, the performance will become unstable, so be careful not to let oil or moisture invade the inside. Especially when it is installed in the gearbox, the oil will penetrate into the inside through the shaft, so it should be completely sealed with the film;
3. Please pay attention to the surface temperature: the highest surface temperature caused by continuous idling, the highest is TL-POC, TL-POD operation is below 90 degrees Celsius, when this value is exceeded, the durability will be greatly reduced. Please use the above-mentioned limit temperature as the standard, and be sure to keep it within the desired sliding work rate when using it;
The hollow shaft magnetic powder clutch is consistent with the working principle of the magnetic powder clutch, but the two are slightly different in structure and design. Please pay attention to the input side and the output side. The hollow shaft magnetic powder clutch is divided into the inner shell rotating hollow shaft magnetic powder clutch and There are two types of housing rotary type hollow shaft magnetic powder clutch. When the magnetic powder clutch and the clutch are used for continuous sliding of winding and unwinding, the product and life are different depending on the conditions of use.

The normal installation method of the hollow shaft magnetic powder clutch uses the adjustment rotating side as the input side to use the iron powder brake clutch, the multi-connected multi-axis, the turret winding and the like, and the continuous idle mode is a high-speed rotation of the output-inside anti-installation. Not recommended for torque characteristics and iron powder life. In addition, the brakes and clutches are used in principle on the horizontal axis and cannot be used in the vertical type.
Application range of hollow shaft magnetic powder clutch: printing machinery, packaging machinery, zipper machinery, food machinery, canning machinery, plastic machinery, winding machinery, woodworking machinery, wire machinery, paper machinery, machine tool factory, photovoltaic equipment, etc. Mainly used in packaging machinery : such as packaging machines, strapping machines, packaging machinery, etc.
