齿轮

To avoid the new thinking of Copernicus that the sun is the center and the earth moves around it once a year and turns on itself once a day, to keep the old thinking of Ptolemy, earth at the center, you need this complicated system of interlocking spheres and gears.

为了排除哥白尼的新理论，也就是：太阳的宇宙中心，地球每年绕日公转一周每天自转一周，并维护托勒密旧学说也就是：以地球为中心，你需要这套球体与齿轮纠缠的复杂系统。

但是，每当我把一道题目塞到他的手里，就能感觉到他大脑里的无数个齿轮开始飞快转动。

The moment load is calculated by multiplying the total payload mass by the acceleration (due to gravity and due to the robot/gantry) by the distance of the payload's center of gravity to the rotating pinion.

弯矩负载的计算式：工作负载质量×加速度（由重力和机器人/门架系统引起）×负载重心到旋转齿轮的距离。

A double helical gear is equivalent to two helical gears of opposite hand, mounted side by side on the same shaft.

双斜齿轮是与反向的并排地装在同一轴上的两个斜齿轮等效。

There is on difference between a crossed helical gear and a helical gear until they are mounted in mesh with each other.

交错轴斜齿轮与斜齿轮之间在被安装后互相捏合之前是没有任何区别的。

Particularly bearing steel, gear steel, spring steel, the steel mold, seamless steel tubes, and other leading products in domestic and international reputation, there are 35 products were Guoyou, Buyou, provincial distinctions, which, carburizing bearing steel, high carbon Chromium bearing steel and steel gear at the national Jinpai Jiang, single-sided Dual Chamber of flat steel country Silver Spring; GCr15 chromium bearing high-carbon steel products physical quality reached the international advanced level; G20 carburizing steel bearing the identification of Japan and Japan Co., Ltd., That reached the international advanced level, the Beijing plant south of locomotives and rolling stock as Mianjian products;∮ 130 mm specifications over four mooring chain is the only steel through the American Bureau of Shipping, Det Norske Veritas, Lloyd's Register, and other well-known international classification societies of the certification and licensing production of varieties.

特别是轴承钢、齿轮钢、弹簧钢、工模具钢、无缝钢管等主导产品在国内外享有盛誉，有35项产品获国优、部优、省优，其中，渗碳轴承钢、高碳铬轴承钢和齿轮钢分获国家金牌奖，单面双槽弹簧扁钢获国家银奖；GCr15高碳铬轴承钢产品实物质量达到国际先进水平；G20渗碳轴承钢经日本东洋株式会社鉴定，认为达到了国际先进水平，被北京南口机车车辆厂视为免检产品；∮130mm规格以上四级系泊链钢是国内唯一在通过美国船级社、挪威船级社、英国劳氏船级社等国际著名船级社的认证和许可批量生产的品种。

文中还对放热系数和输入摩擦热的理论计算作了一些介绍，并通过对一典型齿轮传动的温度计算，初步探讨了求解直齿轮体积温度的若干问题。

In the design of main Reducer and differential gear meshing with are based on the principle of mechanical design and gear transmission design theory and vehicle design, and associated with the intensity check and life calculated.

在主减速器与差速器齿轮啮合设计中主要依据机械设计及齿轮设计理论和汽车传动系设计相结合，并进行相关强度校核与寿命计算。

The differential case supports the differential-pinion gear on a shaft, and this gear meshes with the two bevel gears.

差速器壳支承在行星齿轮轴上，行星齿轮与两个半轴齿轮相啮合。

The machine could add and subtract six-digit numbers, and indicated an overflow of this capacity by ringing a bell; to add more complex calculations, a set of Napier's bones were mounted on it.

当定位齿轮朝9转动时，棘爪便逐渐升高；一旦齿轮转到0，棘爪就&咔嚓&一声跌落下来，推动十位数的齿轮前进一档。
