齿轮

The helix angle is the same on each gear, but one gear must have a right-hand helix and the other a left-hand helix.

螺旋角度是相同的在每个之上齿轮，但是一齿轮一定有一个用右手的螺旋和另一个一个左侧的螺旋。

However, when the helix angle are not equal, the gear with the larger helix angle should be used as the driver if both gears have the same hand.

然而，当节面角不是相等的时，应该使用与更大的节面角的齿轮作为司机，如果两个齿轮有同一只手。

However, when the helix angle are not equal, the gear with the larger helix angle should be used as the driver if both gears have the same hand.

但是，当螺旋角不相等，则齿轮与大螺旋角应作为司机，如果这两个齿轮具有相同的手。

The points-line meshing gear is different from involute gear in choice of helix angle.

点线啮合齿轮螺旋角β的选择，改变了渐开线齿轮为凑中心距或者从优化角度来选取β值的情况。

The helix angle is the same on each gear, but one gear must have a right-hand helix and the other a left-hand helix.

节面角在每个齿轮上相同，但是一个齿轮必须有一个右手螺旋和其他一个左手螺旋。

Apply to calendar herringbone gear、automobile spring、mining machinery、such as winch and high load,low speed friction parts of lubrication,the range of working temperature:-10℃-60

适用于压延机人字齿轮、汽车弹簧、起重机齿轮转盘、矿山机械、绞车和钢丝等高负荷、低转速摩擦部位的润滑；使用温度为：-10℃-60

The contacting simulative analytical model of a pair of herringbone gear used in warship was established,and let the result of calculation be compared with Hertz theory,therefore explained the accuracy,effectiveness and reliability of the contacting element on gear contact stress analysis.

建立了一对舰用人字齿轮接触仿真分析模型，并将计算结果与赫兹理论比较，说明了接触单元在齿轮接触应力分析上的精确性、有效性和可靠性。

Citroen in 1900, Andre Citroen invented the herringbone gear. In 1912, andriy Citroen started employing glyph gear as Citroen company product trademarks.

雪铁龙 1900年，安德烈·雪铁龙发明了人字形齿轮。1912年，安德列·雪铁龙开始用人字形齿轮作为雪铁龙公司产品的商标。

Based on the research on the meshing between hobs and gears the optimum proflie design method of the pre-gringding hob is given,and the optimum profile of the pre-gringding hob used to cut the quasi high-speed locomotive traction gear has been designed according to the application of the traction and their proceeding technolog.

通过对刀齿啮合关系的研究，提出了磨前滚刀齿形优化设计方法，针对准高速机车牵引齿轮的应用和加工工艺特点，对准高速机车牵引齿轮磨前滚刀齿形进行了优化设计。

While most developments evolve over time, some are revolutionary. Ten years ago, helical gears for automobiles were machined from round forgings or bar stock. Today, high-volume gears are cold-extruded or hot-forged with gear teeth in a finished or nearly finished geometry.

大部分产品开发需要时间，有些是一场革命。10年前，汽车用螺旋齿轮还是利用圆锻件或棒材经过机加工制成，可是今天大体积的齿轮都是经过冷挤压或热锻造制作，轮齿的几何图形一次成型或接近成型。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.
