【摘要】：目前在工程中廣泛使用著的普通V帶大多是三層、實(shí)心式V帶結(jié)構(gòu),這種V帶在結(jié)構(gòu)上存在著諸多的不足與缺陷,如V帶的斷面為三層組合式結(jié)構(gòu),它的上下層是膠體、中間是抗拉體,V帶在位于帶輪處進(jìn)行彎曲運(yùn)動時(shí),V帶組合結(jié)構(gòu)中抗拉體與膠體的接觸層處容易產(chǎn)生滑移錯(cuò)位;V帶的彎曲柔性相對差、彎曲應(yīng)力大;V帶的無效質(zhì)量相對多、離心應(yīng)力大;V帶與帶輪間相對摩擦力小、V帶的傳動能力低。另外在很多權(quán)威教科書、獲獎(jiǎng)教材中對V帶傳動進(jìn)行設(shè)計(jì)計(jì)算時(shí)參數(shù)確定的設(shè)計(jì)步驟也存在著不足,V帶傳動設(shè)計(jì)結(jié)果與工程實(shí)際應(yīng)用有較大差異;設(shè)計(jì)的V帶傳動大都沒能實(shí)現(xiàn)理論所期望的嚴(yán)格數(shù)值下的過載打滑,沒有真正起到V帶傳動“安全保護(hù)器”的作用。針對普通V帶結(jié)構(gòu)和教科書中V帶參數(shù)設(shè)計(jì)步驟的不妥,本研究提出了一種兩層、空心、磁性包布式的新型V帶結(jié)構(gòu),并給出了V帶傳動最佳設(shè)計(jì)參數(shù)確定的設(shè)計(jì)步驟。本研究的主要內(nèi)容有以下兩大部分:V帶結(jié)構(gòu)改進(jìn)性研究:將V帶的三層實(shí)體結(jié)構(gòu),改為兩層空心式結(jié)構(gòu),降低了V帶制造成本,改善了V帶加工制造的工藝性;V帶中性層最優(yōu)設(shè)計(jì),將中性層確定在抗拉體與膠體的分界線上,有效地發(fā)揮了V帶抗拉體的承載能力,減少V帶抗拉體與膠體滑移脫落的危險(xiǎn);將V帶的內(nèi)層膠體處適度間隔設(shè)計(jì)為數(shù)排圓柱孔,減輕了無效膠體的重量,增加了V帶的彎曲柔性,有效地減少V帶傳動的離心拉應(yīng)力;V帶包布采用磁性橡膠材料,除了固定抗拉體與膠體外,能增加V帶與帶輪的吸附力,增加V帶的承載能力。在V帶結(jié)構(gòu)改進(jìn)、理論分析的同時(shí),采用了ANSYS軟件進(jìn)行建模,進(jìn)行了應(yīng)力模擬測試,給出了測試結(jié)果,從而在理論上對V帶的新理論、新設(shè)計(jì)提供了支持依據(jù)。V帶傳動的最佳設(shè)計(jì)方法與設(shè)計(jì)步驟:本研究改變了原來V帶設(shè)計(jì)中,率先查圖盲目確定V帶型號,然后再確定其它參數(shù)的設(shè)計(jì)步驟。而是依據(jù)工作機(jī)應(yīng)用特點(diǎn),先確定大離散性的參數(shù),如帶的根數(shù),然后再協(xié)調(diào)確定帶的型號、帶輪直徑和帶長,并可以按不同的帶的根數(shù),得到諸多個(gè)方案提供優(yōu)選,從而為V帶傳動設(shè)計(jì)的最優(yōu)化提供了很好的保障。本設(shè)計(jì)理念及設(shè)計(jì)步驟能保證設(shè)計(jì)結(jié)果恰好近似達(dá)到理想的設(shè)計(jì)臨界狀態(tài),真正實(shí)現(xiàn)V帶傳動起到“過載保護(hù)器”的作用。通過對V帶結(jié)構(gòu)、性能的分析與研究,本文設(shè)計(jì)出一種兩層、多孔式磁性新型V帶,并且改進(jìn)了V帶的計(jì)方法和步驟,提出了最佳設(shè)計(jì)的方法步驟。從而解決了傳統(tǒng)的三層、實(shí)心式普通V帶的缺陷與不足,解決了教科書中V帶傳動設(shè)計(jì)步驟存在的不妥。
[Abstract]:At present, most of the common V-belt used widely in engineering is three-layer, solid V-band structure. There are many shortcomings and defects in the structure of this V-band. For example, the section of V-belt is a three-layer composite structure, and its upper and lower layers are colloids.In the middle, when the tensile V band is bending at the wheel of the belt, the contact layer between the tensile body and the colloid is easy to produce the relative poor bending flexibility of the slip dislocation V band, and the failure mass of the V band with large bending stress is relatively high.The driving capacity of the V belt with high centrifugal stress is lower than that of the belt wheel with low relative friction force.In addition, in many authoritative textbooks, the design steps of determining the parameters of V-belt transmission design in the award-winning textbooks are also different from the actual engineering application.Most of the V-belt drives can not realize the overload slip under the strict value expected by the theory, and do not really play the role of "safety protector" of V-belt transmission.In this paper, a new type of V-belt structure with two layers, hollow and magnetic wrapping is proposed, and the design steps for determining the optimum design parameters of V-belt transmission are given.The main contents of this study are as follows: the three-layer solid structure of V-band is changed into two-layer hollow structure, which reduces the manufacturing cost of V-belt.The optimum design of V-belt neutral layer is improved, the neutral layer is determined on the dividing line between the tensile body and the colloid, the bearing capacity of the V-band tensile body is effectively brought into play, and the danger of V band tensile body and colloidal slippage is reduced.In order to reduce the weight of the ineffective colloid and increase the bending flexibility of the V-belt, the appropriate interval between the colloid in the inner layer of V-belt is designed as several rows of cylindrical holes. The magnetic rubber material is used to effectively reduce the centrifugal tensile stress of V-belt transmission.In addition to the fixed tensile body and colloid, the adsorption force of V-band and belt wheel can be increased, and the load-carrying capacity of V-band can be increased.At the same time of the improvement of V-band structure and the theoretical analysis, the ANSYS software is used to model the model, the stress simulation test is carried out, the test results are given, and the new theory of V-band is theoretically analyzed.The new design provides the best design method and design steps for supporting .V belt drive: this study changes the original V belt design, first looking up the diagram blindly to determine the V belt model, and then determining the design steps of other parameters.On the basis of the characteristics of the work machine application, the parameters of large dispersion, such as the root number of the belt, and then the model of the belt, the diameter and length of the belt wheel can be determined in coordination, and many schemes can be obtained according to the root number of the different bands.Thus it provides a good guarantee for the optimization of V belt transmission design.The design idea and the design steps can ensure that the design result exactly reaches the ideal design critical state, and the V-belt drive plays the role of "overload protector".Based on the analysis and study of the structure and performance of V-band, a new type of V-band with two-layer, porous magnetic is designed, and the counting method and step of V-band are improved, and the method and step of optimum design are put forward.Thus, the defects and shortcomings of the traditional three-layer, solid ordinary V-belt are solved, and the improper design steps of V-belt transmission in textbooks are solved.
