Abstract
In today's world of economic globalization, States of comprehensive national strength and competitiveness embodied in mechanical product design capacity. Because the manufacturing sector is the soul of the design, and manufacture and the manufacture of machinery is the soul, So modern institutions of the studies is the manufacturing base.
This article mainly elaborated has utilized modern vanguard technology in the ring-like leacher transmission system design from in the original traditional pure mechanical foundation---PLC，Causes it to become integration of machinery。
The traditional ring-like leacher machinery control device is by gravity control, because welds the reason can appear the welding deformation frequently, causes it to create the material mouth jamming, needs to open the material gate artificially. As well as the machinery control also has the attrition compared to in a big way, maintains the trouble in a big way, the labor intensity and so on the shortcomings. But PLC has the reliability to be high, ant jamming ability, compatible, the application is flexible, the programming is convenient, the ease of operation, easy to use, the control system design installs the debugging to be convenient, the service is convenient, characteristics and so on function consummation. Thus has made up the shortcoming which the machinery controls, has manifested the integration of machinery merit truly.
The this article primary coverage is composed by two parts: First, the mechanical drive part, mainly spoke the electric motor choice as well as two level of reduction gear transmission design and the ring-like lecher main axle intensity examination. Second, the PLC part, mainly said has controlled the automatic material gate with PLC the switch, as well as the safekeeping of security function and the equipment always stopped.
Keywords：Integration of machinery Transmission device Two level of reduction gear The electrical machinery opens stops controls and Material position PLC controls
