【摘要】：隨著液壓技術(shù)的不斷發(fā)展，對(duì)液壓馬達(dá)的種類和性能提出了更多和更高的要求。當(dāng)實(shí)際工況需要馬達(dá)有多個(gè)穩(wěn)定轉(zhuǎn)矩、轉(zhuǎn)矩的輸出時(shí)，現(xiàn)有的定量馬達(dá)是不能實(shí)現(xiàn)的。針對(duì)這個(gè)不足，從馬達(dá)基本原理出發(fā)，研制出了一系列基于雙轉(zhuǎn)子結(jié)構(gòu)的新型液壓馬達(dá)。在雙轉(zhuǎn)子結(jié)構(gòu)中，一個(gè)定子與兩個(gè)轉(zhuǎn)子分別相互配合，在不改變馬達(dá)輸入流量且沒(méi)有復(fù)雜變量機(jī)構(gòu)的條件下，這種新型馬達(dá)通過(guò)不同輸入進(jìn)、出油口的連接可以輸出多種不同的轉(zhuǎn)速和轉(zhuǎn)矩，實(shí)現(xiàn)了在一個(gè)殼體內(nèi)，多個(gè)馬達(dá)同步工作且相互獨(dú)立的功能。如果當(dāng)作泵來(lái)使用，則可以不用減壓閥同時(shí)工作在不同壓力下同時(shí)輸出多種不同流量以滿足系統(tǒng)需要，這樣就可以在液壓系統(tǒng)中節(jié)省泵、馬達(dá)和閥的使用數(shù)量，同時(shí)節(jié)省了能量消耗。 本文首先對(duì)等寬曲線雙轉(zhuǎn)子偏心殼轉(zhuǎn)多速馬達(dá)的結(jié)構(gòu)和工作原理進(jìn)行了詳細(xì)的介紹，然后借助SolidWorks建立該馬達(dá)的實(shí)體模型和動(dòng)態(tài)運(yùn)動(dòng)過(guò)程。通過(guò)對(duì)馬達(dá)運(yùn)動(dòng)特性的理論分析，建立了滾柱連桿的位移、速度、加速度數(shù)學(xué)模型，同時(shí)分析了等寬曲線雙轉(zhuǎn)子偏心殼轉(zhuǎn)多速馬達(dá)的扭矩特性，，建立了瞬時(shí)扭矩?cái)?shù)學(xué)模型，并對(duì)其數(shù)學(xué)模型進(jìn)行了模擬，得出了雙轉(zhuǎn)子馬達(dá)的扭矩脈動(dòng)規(guī)律。 通過(guò)SolidWorks軟件建立雙轉(zhuǎn)子馬達(dá)的三維實(shí)體模型；對(duì)其物理模型在MATLAB中進(jìn)行仿真分析計(jì)算，得到了連桿滾柱馬達(dá)相應(yīng)零件的速度和加速度仿真曲線。經(jīng)過(guò)對(duì)這些仿真曲線的分析可以得到影響等寬曲線雙轉(zhuǎn)子偏心殼轉(zhuǎn)多速馬達(dá)運(yùn)動(dòng)學(xué)的因素。從而為設(shè)計(jì)出更合理的該馬達(dá)提供依據(jù)。 本文的研究為今后優(yōu)化設(shè)計(jì)，進(jìn)一步提高工作效率、降低生產(chǎn)成本、擴(kuò)展運(yùn)用范圍提供較詳細(xì)的依據(jù)，并為該馬達(dá)未來(lái)的定型生產(chǎn)提供了較詳細(xì)的理論依據(jù)。
[Abstract]:With the development of hydraulic technology, more and more requirements are put forward for the type and performance of hydraulic motors. When the actual working condition requires the motor to have multiple stable torque, torque output, the existing quantitative motor can not be achieved. In order to solve this problem, a series of new hydraulic motors based on double rotor structure are developed based on the basic principle of motor. In a two-rotor structure, one stator and two rotors cooperate with each other, without changing the input flow rate of the motor and without complex variable mechanism, the new motor enters through different inputs. The connection of the outlet can output a variety of different rotational speed and torque, and realize the function of synchronous and independent operation of multiple motors in one shell. If it is used as a pump, it is possible to work at different pressures without reducing the pressure and simultaneously output a variety of different flows to meet the needs of the system, thus saving the use of pumps, motors and valves in the hydraulic system. At the same time, the energy consumption is saved. In this paper, the structure and working principle of the multi-speed motor with double rotor eccentricity shell with equal width curve are introduced in detail, and then the solid model and the dynamic motion process of the motor are established by means of SolidWorks. Based on the theoretical analysis of motor motion characteristics, the mathematical models of displacement, velocity and acceleration of roller connecting rod are established. At the same time, the torque characteristics of eccentric shell and multi-speed motor with double rotor with equal width curve are analyzed, and the instantaneous torque mathematical model is established. The mathematical model is simulated and the torque pulsation law of double rotor motor is obtained. The three-dimensional solid model of the double-rotor motor is established by SolidWorks software, and the simulation curves of velocity and acceleration of the corresponding parts of the roller motor are obtained by the simulation and calculation of the physical model in MATLAB. Through the analysis of these simulation curves, we can get the factors that affect the kinematics of double rotor eccentricity shell to multi-speed motor with equal width curve. Thus, a more reasonable basis for the design of the motor is provided. The research in this paper provides a detailed basis for further optimization design, further improvement of work efficiency, reduction of production cost, expansion of application range, and provides a more detailed theoretical basis for the future finalized production of the motor.
