Interestingly, the paddle wheel or propeller style movement creates lift and thrust. In this case lift adds to thrust.
这个很有意思，明轮推水或者桨叶方式的推水产生了上举力和向前的推力，在这种情况下上升力和推力会叠加在一起。
The motors are fitted inside each wheel while the wheel rim is designed to work as a propeller for cooling it off.
马达装有内的每个车轮，而车轮轮辋的设计工作作为一项螺旋桨冷却将它关闭。
It serves to replace or complement the propeller, wheel, jet engine, solid fuel, etc, in the area of transportation and use in space travel.
它在运输和太空旅行应用领域中，用来取代或补充推进器、轮盘、喷气发动机、固体燃料等。
In this paper the author emphasizes the importance of balancing the rotating parts, such as crankshaft, flywheel, propeller shaft, wheel and tyre, etc. during automobile repair.
分析了汽车维修中曲轴、飞轮、传动轴、车轮、轮胎等旋转零件进行平衡试验的重要性。

纸箱类：裁纸横切刀、修边刀、开槽刀、风车碎纸机刀、散桨机刀。流水线单刀片及CBN砂轮等。
BMW Corporation of West Germany has developed a torsion rig for universal joint propeller shaft and axle shaft for the use of testing four-wheel-drive cars.
联邦德国的BMW公司开发了一种万向节传动轴与半轴的扭转试验台，专供四轮驱动型桥车试验用。
The invention is characterized by the combination of the blades of a propeller and the wheel rim or ring rib of a flywheel, and has dual functions of a flywheel and a rotor wing or a propeller;
本发明是一种旋轮翼，它具有缘肋和桨叶，其特征是：把旋翼或螺旋桨的桨叶和飞轮的轮缘及加强环肋结构有机地结合成为一个整体，使之具有飞轮与旋翼或螺旋桨的双重功能；
The forming apparatus includes motor, belt wheel, spiral propeller, material bin, piston driving system, piston, mold, pedestal, forming barrel and other parts.
其成型设备包括：电机、皮带轮、螺旋绞龙推进器、料斗、活塞驱动系统、活塞、锥模、凸模、法兰、机座、推杆、成型筒等。
The hypoid gear is in common use today due mainly to the fact that the offset pinion allows the propeller shaft to be set below, (for cars) or above, (for commercial vehicles) the crown wheel center.
现在的主减速器普遍使用准双曲面圆锥齿轮，这主要是因为 主动锥齿轮的偏移允许轿车上传动轴布置得比从动锥齿轮低 一些，而商用车上又允许布置得比从动锥齿轮高一些。
