【摘要】：自20世紀(jì)80年代至今,ZL50型輪胎式裝載機(jī)一直是中國國內(nèi)裝載機(jī)的主力機(jī)型。滾柱式超越離合器與液力變矩器聯(lián)合使用在裝載機(jī)上,具有車輛通過性強(qiáng)、自動無級變速、自動防止發(fā)動機(jī)過載等諸多優(yōu)點(diǎn),是裝載機(jī)傳動系統(tǒng)的最常見結(jié)構(gòu)之一。 本文簡單介紹了超越離合器的相關(guān)背景知識和裝載機(jī)的相關(guān)知識,簡單介紹了滾柱式超越離合器的工作過程以及滾柱式超越離合器在裝載機(jī)傳動系統(tǒng)中的作用。 對于滾柱式超越離合器的設(shè)計及工藝分析,最常見的假設(shè)都是超越離合器的滾柱和內(nèi)環(huán)凸輪均勻受力。而在實際工況中,超越離合器的所有滾柱按照理想狀態(tài)均勻受力是很少存在的,并且,超越離合器的微觀上的受力不均勻,往往是導(dǎo)致早期疲勞源的主要原因。 本文介紹了有限元法的相關(guān)知識,然后對ansys和ansys workbench軟件進(jìn)行簡單介紹,并根據(jù)裝載機(jī)傳動系統(tǒng)的實際工況,以地面附著條件將導(dǎo)致輪胎打滑限制發(fā)動機(jī)動力的發(fā)揮為條件確定了工作載荷,通過動力匹配計算,系統(tǒng)地對滾柱式超越離合器進(jìn)行了受力分析；在此基礎(chǔ)上對超越離合器滾柱均勻受力和不均勻受力都進(jìn)行了有限元分析。 本文介紹了滾柱式超越離合器的主要失效形式,然后通過對滾柱式超越離合器失效反饋數(shù)據(jù)和制造過程制造過程的分析,總結(jié)影響滾柱式超越離合器失效產(chǎn)生的因素。最后分析了結(jié)構(gòu)參數(shù)和制造誤差對離合器失效的影響。 本文在對滾柱式超越離合器的失效分析與受力分析的基礎(chǔ)上,在結(jié)構(gòu)設(shè)計、材料設(shè)計、工藝設(shè)計等方面提出了提高超越離合器可靠性的措施。通過內(nèi)環(huán)凸輪和隔離環(huán)的材料、加工工藝等提出改進(jìn)措施,提高它們的可靠性,并對隔離環(huán)和彈簧定位進(jìn)行結(jié)構(gòu)優(yōu)化,改善它們的受力狀態(tài),使之更加趨于合理。 通過大量的實踐和改進(jìn),ZL50型超越離合器的故障率大幅度的下降,由異常波動時期的4%-5%下降到1%甚至0.5%以內(nèi),并且進(jìn)一步通過了過程穩(wěn)定控制,達(dá)到了ISO 9000國際標(biāo)準(zhǔn)的產(chǎn)品性能要求。
[Abstract]:Since 1980 s, ZL50 tire loader has been the main type of domestic loader in China. Combined use of roller overrunning clutch and hydraulic torque converter in loader has many advantages, such as strong vehicle passing, automatic stepless speed change, automatic prevention of engine overload, and so on. It is one of the most common structures of loader transmission system. This paper briefly introduces the background knowledge of overrunning clutch and the relative knowledge of loader, and briefly introduces the working process of roller overrunning clutch and the function of roller overrunning clutch in the drive system of loader. For the design and process analysis of the roller overrunning clutch, the most common assumption is that the roller and the inner ring cam of the overrun clutch are subjected to uniform force. However, in the actual working conditions, all the rollers of the overrunning clutch are rarely subjected to uniform forces according to the ideal state, and the uneven force on the micro level of the overrunning clutch is often the main cause of the early fatigue source. This paper introduces the knowledge of finite element method, and then introduces the software ansys and ansys workbench simply, and according to the actual conditions of the loader transmission system, The working load is determined under the condition that the ground attachment condition will lead to the tire skidding and limiting the engine power. The force analysis of the roller overrunning clutch is carried out systematically through the dynamic matching calculation. On this basis, the finite element analysis of uniform force and uneven force on the roller of overrunning clutch is carried out. This paper introduces the main failure forms of the roller overrunning clutch, and then summarizes the factors that affect the failure of the roller overrunning clutch through the analysis of the failure feedback data and the manufacturing process of the roller overrunning clutch. Finally, the effects of structural parameters and manufacturing errors on clutch failure are analyzed. On the basis of failure analysis and force analysis of roller overrunning clutch, this paper puts forward some measures to improve the reliability of overrunning clutch in the aspects of structure design, material design, process design, etc. Through the material of inner ring cam and isolation ring, processing technology and so on, the improvement measures are put forward to improve their reliability, and the structure of isolation ring and spring positioning are optimized to improve their stress state and make them more reasonable. Through a great deal of practice and improvement, the failure rate of the ZL50 type overrunning clutch has been greatly reduced from 4- 5% in the abnormal fluctuation period to 1% or even 0.5%, and the process stability control has been further passed. Meet the ISO 9000 international standards of product performance requirements.
