Model gk39 high - speed bag sewing closer is adopted a special part, which the needlecan move together with the looper. the machine is equi pped with aluminum alloy house, gear running, needle bar and looper system to form double - thread chain stitch. the main running parts are adopted bearing and the machine has the special design such as automatic oil dripping lubrication system, roller feeding and needle feeding in step having the automatic cutting system
說明：本機gk39為高速封包縫紉機，是唯一採用「紉針機構」針同步的封包縫紉機，採用鋁合金外殼，輪傳動，針桿挑線和彎針勾線，組成雙線鏈式線跡。主要轉動部位採用軸承，並配有自動滴油潤滑油路。 -
Therefore if the closed planetary gear train and the differential plahetary gear train set up a multistage mixed gear train, we will obtain a winch on automobile crane which satisfy the request of double speed, great transmission ratio and small volume
因此將差動和封閉行星輪系組成多級混合輪系，就可得到一種滿足汽車起重機上的卷揚機雙速、大傳動比、小體積要求的傳動機構。 -
Following the successful delivery of new ferry v and new ferry vi from singapore, first ferry ( macau ) commissioned austal ships pty ltd, an australia - based world leader in the construction of high speed aluminum vessels, to build three double deck catamarans with total consideration of hk $ 180 million in 2001. the three new catamarans, namely new ferry lxxxi, new ferry lxxxii and new ferry lxxxiii are designed to gear to passengers demand for first - class service ; speed, smooth and comfortable are their intrinsic values
8億，委託以建造高速雙體船聞名的澳洲澳斯達船廠建造三艘雙層高速雙體船，即新輪捌拾壹、新輪捌拾貳及新輪捌拾? ；三艘新船揉合高速、流暢以及舒適等優點於一身，設計以客為尊，盡顯對乘客的關懷。 -
In addition for raising rise - and - fall - speed of goods when crane is in empty load and light load situation we need a improved double - speed - type transmission based on the original single - speed winch. using the differential planetary gear train that can do movement synthesis precisely can achieve this goal
另外為了提高起重機空鉤和輕載時的貨物升降速度，要求在舊型的單速卷揚機上進行改進實現雙速傳動，而利用差動行星輪系可進行運動合成的特點能達到這一目的。
