1 magnetic powder brake and magnetic powder clutch using DC24V DC power as the excitation source, the company production of ST-202P, ST-203P, ST-204P power supply designed with the exciting current of 1A-4A, can be used according to the specifications of the size matching.
2 magnetic powder brake and clutch in the transport process often makes the magnetic particle aggregation below, jam the working gap, so that before use will appear occasionally "stuck" phenomenon, this time only the magnetic powder brake and clutch along the circumferential direction of the whole rolling or lever shaft coupling, the magnetic powder dispersed, and then can be running in: the first 20% of rated current operation after a few seconds off again electrify, repeated several times can be normal use.
Magnetic particle in 2000N ¡¤ m above the magnetic powder brake 3 rated torque on the other device, can be in before running or running process by magnetic filling hole gradually into the. Pay attention to add powder can not have the exciting current.
Rings hole magnetic powder brake are powder filling holes, small size brake as its circumference special screw top.
Special tip: add lubricating oil and water into the forbidden powder filling hole.
Magnetic powder brake and clutch 4 natural cooling fan, blower, available for surface cooling, magnetic powder brake 50N m more than a single and double water cooling water cooling and clutch in the operation of colleagues, must be cooled, otherwise the work surface will produce high-temperature, affect the service life.
5 installation of coupling is forbidden to beat. Note the installation adjusting center height, concentric and coaxial degree.
6, please refer to the installation method of formal (the high-speed rotating side as the input side) to the use of magnetic powder clutch. If the mechanical structure to input and output shaft installed, please make sure to 1000R/MIN to use. The input shaft and the output shaft in turn installed you can make the machine long time idling, magnetic powder by mixing, will greatly shorten the service life of the magnetic powder clutch. 2, please pay attention to moisture. Magnetic damp words, performance will become unstable, so be careful, don't let the oil or water penetrated inside. Especially when installed in the gear box, the oil branch through the shaft part penetrated inside, so use film completely sealed.
7, please note that the surface temperature. The highest surface temperature caused by continuous operation for operation below 90 degrees, more than the value, durability will be greatly reduced. Please be sure to the boundary temperature as the standard, when use must keep on the sliding work acceptable rate.
Magnetic powder brake is composed of a transmission unit (input shaft) and a driven unit (output shaft) and merged. In between the two groups of unit space, filled with granular powder (Hugh volume of about 40 microns). When the magnetic coil not conductive, not from the drive shaft torque to the driven shaft, but if the coil is energized, the magnetic force and magnetic hardening phenomenon in attractive, even following the sliding between the torque transmission. The principle and magnetic powder clutch brake is similar, only the drive unit into a fixed unit.
