Design of a New Type of Mechanical Mechanism Demonstration Teaching Aid

In order to solve the problem of mechanical professional courses classroom boring, designed a new interest linkage mechanical mechanism demonstration teaching aid. The teaching aid comprises five sets of mechanical mechanism, respectively, gear mechanism, Geneva mechanism, slider crank mechanism, an eccentric wheel mechanism and a crank rocker mechanism, the linkage mechanism device to run a series of each mechanism are mounted in a plastic box, the demonstration started general switching power supply, the small ball rolling into the box through the rubber hose, connected circuit, the electromagnetic lock electric lock indent, frame and a mechanism that plate falling, plate engraved with the mechanism of description, teaching effect. The plate falling touch stroke switch, the motor power, operation mechanism, for each mechanism are equipped with relay, so after a period of time will make the organization a power operation, in the same way, until finally a mechanism. The teaching aid has strong interest, is beautiful and practical, easy to use, and has good practical value.
