摘 要:減速器，又名減速機(jī)、減速箱，主要用于在原動(dòng)機(jī)和工作機(jī)或執(zhí)行機(jī)構(gòu)之間起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用。減速器主要由傳動(dòng)零件(齒輪或渦輪蝸桿)、軸、軸承、箱體以及其他附件所組成，在現(xiàn)代機(jī)械中應(yīng)用極為廣泛，從交通工具的船舶、汽車、機(jī)車，建筑用的重型機(jī)具，機(jī)械工業(yè)所用的加工機(jī)具及自動(dòng)化生產(chǎn)設(shè)備，到日常生活中常見的家電、鐘表等，幾乎都可以見到它的蹤跡，其應(yīng)用從大動(dòng)力的傳輸工作到小負(fù)荷、精確角度的傳輸都要用到減速器。減速器是原動(dòng)機(jī)和工作機(jī)之間的獨(dú)立的閉式傳動(dòng)裝置，用來降低轉(zhuǎn)速和增大轉(zhuǎn)矩，以滿足工作需要，選用減速器時(shí)應(yīng)根據(jù)工作機(jī)的選用條件，技術(shù)參數(shù)，動(dòng)力機(jī)的性能，經(jīng)濟(jì)性等因素，比較不同類型、品種減速器的外廓尺寸，傳動(dòng)效率，承載能力，質(zhì)量，價(jià)格等，選擇最適合的減速器。減速器按用途可分為通用減速器和專用減速器兩大類，兩者的設(shè)計(jì)、制造和使用特點(diǎn)各不相同。 在全液壓頂驅(qū)系統(tǒng)中采用的減速器屬于專用減速器，該裝置采用了高速小扭矩液壓馬達(dá)，兩級(jí)齒輪減速器減速，雙閉環(huán)齒輪傳動(dòng)。動(dòng)力源是由兩臺(tái)軸向柱塞馬達(dá)提供的液壓能，經(jīng)齒輪減速箱減速帶動(dòng)鉆具旋轉(zhuǎn)。 關(guān)鍵詞：液壓頂驅(qū) 減速器 齒輪
ABSTRACT:Reducer, also known as reducer, gear boxes, mainly used in the original motivation and working machine or actuator from the match between speed and torque delivery role. Reducer mainly by the transmission parts (gears or worm), shafts, bearings, housing, and other accessories that consists in the application of modern machinery is extremely broad, from transport ships, automobiles, motorcycles, heavy machinery used in construction, machinery industrial processing of used machinery and automated production equipment, to the daily life of common household appliances, watches, etc., almost all traces of it can be seen, its application from the large to the small momentum transfer work load to be used in the transmission of precise angles reducer. Reducer is the prime mover and working machines closed between independent drive means for reducing speed and increasing torque to meet operational needs, the choice should be based on the work machine reducer selection criteria, technical parameters, power machine performance, economy and other factors, comparing different types of varieties reducer dimensions, drive efficiency, carrying capacity, quality, price, etc., select the most suitable reducer. Reducer use can be divided into general and special reducer reducer two categories, both the design, manufacture and use characteristics of each are not identical. In full hydraulic top drive system used in the reducer is dedicated reducer, the device uses a high-speed low torque hydraulic motors, two gear reducer reducer, double loop gear. Power source is provided by two axial piston hydraulic energy, driven by the gear box reducer drill rotation. Keywords: hydraulic pressure top drive reducer gear |
