【摘要】：全球有超過70%的面積被海洋覆蓋,隨著全球經濟現(xiàn)代化發(fā)展,人們對資源的需求與日俱增,但是陸地上的石油、天然氣、煤炭等能源卻越來越少,這就促使人們將目光轉向資源豐富的海洋。據1995年估計,世界近海已探明的石油資源儲量為379億噸,天然氣的儲量為39萬億立方米,海底蘊藏的油氣資源儲量約占全球油氣儲量的1/3。所以,探索海洋對我國乃至全世界其他國家來說刻不容緩。本文以給深海探測器提供動力的液壓動力源為研究分析對象,研究了動力源的結構以及動力源的傳動聯(lián)接系統(tǒng)。結構方面,本著輕量化的設計理念,液壓泵及液壓閥直接安裝到油箱中(內置式),補償器活塞通過油箱內壁定位,電機與液壓泵共用端蓋。傳動方面,為了節(jié)約空間并保證動力源傳動的可靠性,電機與液壓泵之間采用漸開線花鍵進行傳動,并從接觸強度的角度對花鍵的對中及不對中傳動進行分析,得出了花鍵接觸面的應力分布情況。本文主要包括以下三部分內容：1.結合國內外對深海設備的相關研究,介紹了本文涉及的深海集成油壓動力源的結構布局以及其補償器、液壓泵、電機的選型情況,并對電機的功率、液壓泵流量、補償器的補償量、及傳動軸的攪油損失進行校核。以6kW系列動力源為例,對動力源的漸開線花鍵進行選型,并對所選花鍵進行理論應力校核。2.動力源對中傳動時,通過對花鍵傳動的接觸分析得出花鍵傳動的接觸應力、摩擦剪切應力、法向穿透距離以及切向滑移的分布規(guī)律。同時研究了軸向接觸長度、法向剛度系數以及切向摩擦系數三個因素對花鍵傳動特性的影響,分析得出花鍵傳動最佳軸向接觸長度,并給出了剛度系數和摩擦系數的選擇范圍。3.動力源不對中傳動時,分析了平行不對中及角向不對中對花鍵傳動特性的影響,得出了能夠有效控制花鍵傳動應力的不對中量大小,為動力源傳動的故障檢測提供參照。
[Abstract]:More than 70% of the world's total area is covered by the ocean. With the development of the global economic modernization, people's demand for resources is increasing. However, the energy, such as oil, natural gas, coal and so on, is less and less, which makes people turn to the ocean with abundant resources. According to the estimation in 1995, the proven offshore oil reserves in the world are 379 billion tons, and the reserves of natural gas are 39 trillion cubic meters. The reserves of oil and gas resources on the seabed account for about 1/3 of the global oil and gas reserves. Therefore, the exploration of the ocean is of great urgency to our country and to the rest of the world. This paper studies the structure of the power source and the transmission connection system of the power source, taking the hydraulic power source which provides the power of the deep-sea detector as the research object. In terms of structure, based on lightweight design concept, hydraulic pump and hydraulic valve are directly installed into the tank (built-in type). The compensator piston is positioned through the inner wall of the fuel tank, and the motor and hydraulic pump share the end cover. The transmission, in order to save space and ensure the reliability of power transmission, the motor and hydraulic pump adopts involute spline transmission, and from the angle of the contact strength of the spline transmission and misalignment are analyzed, the contact stress distribution of the spline. This paper mainly includes the following three parts: 1. based on the related research on deep-sea equipment at home and abroad, introduces the structure and layout of the integrated deep-sea oil pressure power source and selection of the compensator, hydraulic pump, motor, and the motor power, hydraulic pump, flow compensator compensation, and the transmission shaft stirring oil loss of check. Taking the 6kW series of power sources as an example, the selection of the involute spline of the power source is selected and the theoretical stress of the selected spline is checked. 2., when the power source is in the middle drive, the contact stress, frictional shear stress, normal penetration distance and tangential slip distribution of spline drive are obtained through contact analysis of spline transmission. At the same time, the influence of three factors, including axial contact length, normal stiffness coefficient and tangential friction coefficient, on the transmission characteristics of spline is studied. The optimum axial contact length of spline drive is analyzed, and the selection range of stiffness coefficient and friction coefficient is given. 3., when the power source is misalignment, the influence of parallel misalignment and angular misalignment on the transmission characteristics of spline is analyzed, and the size of the misalignment size that can effectively control the stress of spline transmission is obtained, which provides a reference for fault detection of power source transmission.
