【摘要】：薄煤層滾筒式采煤機(jī)對保證煤礦高產(chǎn)高效生產(chǎn)至關(guān)重要。牽引部是采煤機(jī)的重要組成部分,它的性能決定著滾筒式采煤機(jī)的適應(yīng)性、可靠性、穩(wěn)定性。由于受到煤層厚度的限制,在狹小的工作空間里,設(shè)計(jì)滿足工作要求的牽引部是必須要解決的問題,本文通過現(xiàn)代設(shè)計(jì)方法,優(yōu)化牽引部的性能參數(shù),最終設(shè)計(jì)出薄煤層牽引部大傳動比牽引驅(qū)動裝置和具有大模數(shù)行走輪的牽引機(jī)構(gòu)。滿足了采煤機(jī)對牽引部的要求。本文以某煤礦工作面的煤層賦存情況及產(chǎn)量要求為依據(jù),設(shè)計(jì)了采煤機(jī)總體參數(shù);按照“三機(jī)配套”原則,確定了牽引部的外形尺寸,傳動系統(tǒng),牽引驅(qū)動裝置軸系的相關(guān)參數(shù),進(jìn)行了傳動比分配,討論了牽引驅(qū)動裝置的傳動形式及布置方式,介紹了牽引部附屬裝置的功能及設(shè)計(jì)方法;接著對牽引驅(qū)動裝置的傳動齒輪和軸承進(jìn)行受力分析及強(qiáng)度校核;并以傳動裝置中外形尺寸最大的行星傳動機(jī)構(gòu)體積最小為優(yōu)化目標(biāo),進(jìn)行了優(yōu)化設(shè)計(jì),運(yùn)用MATLAB中的最小函數(shù)求解,最終確定了牽引驅(qū)動裝置的相關(guān)參數(shù);利用三維軟件建立了行走驅(qū)動裝置有限元模型,并對受力最復(fù)雜的行走輪進(jìn)了有限元設(shè)計(jì)。最終解決了在有限空間內(nèi),采煤機(jī)大傳動比行走裝置的設(shè)計(jì)問題。按國家標(biāo)準(zhǔn)要求,利用專業(yè)試驗(yàn)平臺對牽引部進(jìn)行了型式試驗(yàn),并通過實(shí)時(shí)監(jiān)控系統(tǒng)監(jiān)控試驗(yàn)過程并實(shí)時(shí)采集了試驗(yàn)數(shù)據(jù),通過試驗(yàn)數(shù)據(jù)分析,設(shè)計(jì)的牽引部傳動效率高、工作可靠穩(wěn)定,并通過了薄煤層滾筒式采煤機(jī)的整機(jī)試驗(yàn);通過整機(jī)工業(yè)性試驗(yàn),驗(yàn)證了牽引部設(shè)計(jì)合理性、滿足了采煤機(jī)工作的性能要求。
[Abstract]:The thin coal seam drum shearer is very important to ensure the high production and high efficiency of coal mine. The traction part is an important part of the shearer, and its performance determines the adaptability and reliability of the roller shearer. Stability. Due to the limitation of coal seam thickness, it is necessary to solve the problem of designing traction parts that meet the requirements of work in the narrow workspace. This paper optimizes the performance parameters of traction parts by modern design method. Finally, the large ratio traction drive device of thin coal seam traction part and the traction mechanism with large modulus walking wheel are designed, which meet the requirements of the shearer for the traction part. This paper is based on the coal seam occurrence and production requirements of a coal mining face. The overall parameters of the shearer are designed, and according to the principle of "three machines matching", the shape and size of the traction part, the transmission system and the relevant parameters of the shaft system of the traction driving device are determined, and the transmission ratio is allocated. This paper discusses the driving form and arrangement of the traction drive, introduces the function and design method of the accessory device of the traction part, and then analyzes the force and the strength of the driving gear and bearing of the traction drive. Taking the minimum volume of the planetary transmission mechanism with the largest shape in the transmission device as the optimization objective, the optimization design is carried out, and the relevant parameters of the traction drive device are finally determined by solving the minimum function in MATLAB. The finite element model of walking drive device is established by using three dimensional software, and the finite element design of walking wheel with the most complicated force is designed. Finally, the design problem of large driving ratio walking device of shearer in finite space is solved. According to the requirement of national standard, The type test of the traction department is carried out by using the professional test platform, and the test process is monitored by the real-time monitoring system and the test data are collected in real time. Through the analysis of the test data, the designed traction part has high transmission efficiency and reliable and stable operation. Through the whole machine test of thin coal seam drum shearer and the industrial test of the whole machine, the rationality of the design of the traction part is verified, and the performance requirement of the shearer is satisfied.
