education system utilizing the powertrain

摘要

DC motor rotation -> shaft rotation -> chain and timing belt rotation -> chain rotation V belt and round belt -> timing belt actuating ball screw according to LM guide -> coupling axis The rack and pinion are operated -> Anti-backlash gear, Geneva gear, and gears in the gearbox are rotated. HMI tells the location of each power element through a lamp and explains each power element. Operating principle Operates HMI by distributing PLC, which is an electric element. Benefits You can see the power trains shown in the text and photos in action. By using hmi and plc, you can bring an effect that can be recognized at a glance. V belts, chains, couplings, timing belts, racks and pinions, ball screws, Geneva gears, anti-backlash gears, and many more types of power units are gathered in one place. After the operation using the HMI controller, it became possible to operate through the PLC. The bearing housing and Geneva gears processed with precision using a machining center, When the axis processed with the base and CNC lathe presses the power button through the PLC, the DC module The motor rotates forward and the axis connected to the bevel gear rotates and is connected to the motor through the bevel gear. The power is transmitted in the direction perpendicular to the rear axis, and the other axis rotates through the coupling. Power is transmitted to the smaller shaft, and the shaft is also the sprocket of the chain and the timing belt. The chain and timing belt are operated by transmitting power to the pulley. Turn the pulley to operate. At this time, due to the circular belt and timing belt that operate, the ball screw As a result of the rotation, the LM Guide makes a reciprocating motion. Also connected with the timing belt another The other axis rotates the bevel gear to operate the worm gear with a reduction ratio, so that the speed is slower than before. It activates the lek and pinion, and also activates the zero backlash gear, and the gears are interlocked. By operating another worm gear, a large bevel gear is operated to transmit power to the large bevel gear. Transmits power in two directions. One of the two power sources is the operation of six spur gears (spur gears). The Geneva gear is connected to another bevel gear and moves in the other direction. Works. In addition, both ends of the LM guide are A limit switch is installed in the front and reverse rotation before the rake is removed. The rotation direction is changed by forward rotation, and the DC motor rotates when there is an abnormality when the gears are engaged. It is set to stop the rotation of the DC motor when pressing the emergency switch to stop the motor. All. Also, by making forward and reverse rotation buttons, the power transmission elements rotate forward and reverse respectively. I made it possible to see how they do.
