摘   要

      往復(fù)式給煤機(jī)在我國煤礦，選煤廠及其它行業(yè)應(yīng)用已幾十年。生產(chǎn)實(shí)踐證明，給煤設(shè)備的可靠性,直接影響整個(gè)生產(chǎn)系統(tǒng)的正常運(yùn)行。現(xiàn)有的往復(fù)式給煤機(jī)的具有生產(chǎn)能力小、安裝和拆卸不方便、受力不均勻等缺點(diǎn)，因此,改進(jìn)并擴(kuò)大現(xiàn)有Ｋ型往復(fù)給煤機(jī)的產(chǎn)量是完全必要的。
本說明書主要論述研究了：往復(fù)式給煤機(jī)的發(fā)展概況；工用、組成；工作原理、特點(diǎn)；使用中存在的問題及改進(jìn)措施，安裝和維護(hù)等內(nèi)容。
本說明書設(shè)計(jì)主要是：先通過設(shè)計(jì)計(jì)算給煤機(jī)的主要運(yùn)動(dòng)部件即給煤槽的運(yùn)行速度和所受的運(yùn)行阻力來求得電動(dòng)機(jī)功率。用電動(dòng)機(jī)功率來設(shè)計(jì)減速器。然后在設(shè)計(jì)出曲柄連桿機(jī)構(gòu)，給煤槽，拖滾組件等主要運(yùn)行部件。最后設(shè)計(jì)給煤機(jī)箱體，傳動(dòng)平臺(tái)等輔助部件。最后完成給煤機(jī)的總體裝配。在本次往復(fù)式給煤機(jī)的設(shè)計(jì)過程中，著重對減速器、傳動(dòng)平臺(tái)、曲柄連桿機(jī)構(gòu)、托輥進(jìn)行了分析和設(shè)計(jì)。對重要的部件進(jìn)行了受力分析、強(qiáng)度的校核，根據(jù)其常見失效形式、影響因素及基本設(shè)計(jì)要求，給出了重要部件的受力分析、強(qiáng)度和剛度的設(shè)計(jì)方法。

ABSTRACT

Reciprocating feeder in China's coal mines, coal preparation plant and other industry application has been for several decades. Practice has proved that the reliability of equipment to the coal, a direct impact on the whole production system the normal operation. Reciprocating the existing feeder with small production capacity , installation and removal of inconvenient, Shouli Bu uniform, and other shortcomings Therefore, the improvement and expansion of existing K-Reciprocating coal feeder is completely necessary.
    The statement focuses on the study: Reciprocating to the development of coal, the use, composition, working principle and its characteristics, the use of the existing problems and improvement measures, installation and maintenance, and other content. Electric motor power to design reducer. And then design a crank linkage to the coal shafts, drag roller components, and other major components operation
The design specification is: first through the design calculations for coal is the main moving parts to the coal shafts running speed and suffered the motor running resistance to achieve power. To the final design of coal chassis, transmission platforms, such as auxiliary components. Coal-to finalize the overall assembly. Reciprocating in this coal to the design process, focusing on reducer, transmission platform, crank linkage, Idler for the analysis and design. Important components of the stress analysis, strength check, in accordance with its common failure mode, Factors and basic design requirements, is an important component of the stress analysis, strength and stiffness of the design method.

Keywords : Reciprocating to the coal; Reducer; Crank linkage;Suppling coal shaft.
