④ 跪求！！蝸桿傳動或者鏈傳動 優化設計的外文文獻！！！ 跪求
蝸桿傳動 蝸桿傳動由蝸桿和蝸輪組成，蝸桿一般作主動件，蝸輪作從動件，做減速運動！
蝸桿傳動可用來傳遞空間兩交錯軸之間的運動和動力！
蝸桿傳動是在空間交錯的兩軸間傳遞運動和動力的一種傳動，兩軸線間的夾角可為任意值，常用的為90°。這種傳動由於具有結構緊湊、傳動比i大、傳動平穩以及在一定的條件下具有可靠的自鎖性(Z=1)等優點，它廣泛應用在機床、汽車、儀器、起重運輸機械、冶金機械及其它機器或設備中。
1 蝸輪蝸桿的形成
蝸桿蝸輪傳動是由交錯軸斜齒圓柱齒輪的輪齒分度圓柱面上纏繞一周以上，這樣的小齒輪稱為蝸輪。為了改善嚙合狀況，將蝸輪分度圓柱面的母線改為圓弧形，使之將蝸桿部分地包住，並用與蝸桿形狀和參數相同的滾刀范成加工蝸輪，這樣齒廓間為線接觸，可傳遞較大的動力。
蝸桿蝸輪傳動的特徵：
其一，它是一種特殊的交錯軸斜齒輪其二，它具有螺旋傳動的某些特點，蝸桿相當於螺桿，蝸輪相當於螺母，蝸輪部分地包容蝸桿。 還可以是蝸桿相當於齒條，蝸輪相當於齒輪，與范成法類似。
2 蝸桿傳動的類型
按蝸桿形狀的不同可分：
1．圓柱蝸桿傳動-普通圓柱蝸桿（阿基米德蝸桿、漸開線蝸桿、法向直廓蝸桿、錐麵包絡蝸桿）和圓弧蝸桿。
鏈傳動 鏈傳動是通過鏈條將具有特殊齒形的主動鏈輪的運動和動力傳遞到具有特殊齒形的從動鏈輪的一種傳動方式。
鏈傳動有許多優點，與帶傳動相比，無彈性滑動和打滑現象，平均傳動比准確，工作可靠，效率高；傳遞功率大，過載能力強，相同工況下的傳動尺寸小；所需張緊力小，作用於軸上的壓力小；能在高溫、潮濕、多塵、有污染等惡劣環境中工作。
鏈傳動的缺點主要有：僅能用於兩平行軸間的傳動；成本高，易磨損，易伸長，傳動平穩性差，運轉時會產生附加動載荷、振動、沖擊和雜訊，不宜用在急速反向的傳動中。因此，鏈傳動多用在不宜採用帶傳動與齒輪傳動，而兩軸平行，且距離較遠，功率較大，平均傳動比准確的場合。
常見實例：自行車
若要將自行車速度增大，應該將牙盤半徑增大，飛輪半徑減小，後輪半徑增大。現在的變速自行車就是這樣設計的。

About Sheet Metal Fabrication Services
Sheet metal fabrication services providers manufacture components by cutting, bending, rolling, forming, stamping and welding sheet metal. Components manufactured through sheet metal fabrication services are used in a variety of applications such as enclosures, computer equipment, HVAC components, kitchen and sanitary equipment, machine tools and other instrial applications. Sheet metal fabrication services include a diverse range of processes used to fashion sheet metal into usable procts. These processes may be broken down into three rough categories, cutting, forming, and finishing services.
Sheet metal cutting services includes a number of techniques used to cut metal into smaller pieces so that it can be molded or formed into components. Common types of sheet metal cutting involve shearing, electrical discharge machining (EDM), laser cutting, water jet and abrasive cutting. Shearing uses a specialized machine to cut sheet metal by applying shear stress. This process is used to cut large sheets of metal into smaller parts. Laser cutting machines use laser light to cut or etch holes or profiles. Laser cutting machines are very precise programmable pieces of equipment. Water jets and water abrasive jets rely on highly pressurized water (20,000 - 60,000 psi) flowing through a nozzle or "jewel" approximately 0.010" in diameter. Advantages include almost no material heating ring cutting, low side loads, and ability to achieve complex shapes and tight inside radii. Low fixturing costs and fast setup and programming times make this process very suitable for prototypes or short runs. It is most widely used for two-dimensional cutting; three-dimensional machining is possible in specialty applications
Wire electrical discharge machining (EDM) equipment is used to cut conctive materials using a thin electrode. The electrode is a thin wire (typically .004"-.012") that follows a programmed path. The wire does not physically contact the part. It is charged to a certain level and surrounded by de-ionized water. A spark is generated that jumps the gap and melts a small amount of material on the part.
Sheet metal forming processes include those actions used fashion metal into specific shapes or semi-finished pieces. Common techniques include bending and forming, rolling, stamping, punching, welding, and hardware and fastener creation. Bending and forming processes are used to shape the sheet metal to its final shape. In the rolling process, a series of roll stands is used to progressively shape or bend a strip of flat-rolled metal to a desired cross section. Stamping is the process of impressing surface definition and three-dimensional designs onto materials with pressurized tools and dies. Punching is the process of punching holes in the sheet metal. Welding is the joining of metals and metal parts by melting and re-forming a metal bond between materials, with or without additional filler metal. Hardware and fastener creation is the capability to supply and integrate hardware such as handles, latches and threaded, self-clinching fasteners used to provide threads in sheet metal that is too thin or soft to be tapped.
