齿轮

Following is the important part of automatic transmission: planetary gear sets.

下面就是自动变速器的最主要的机构------行星齿轮机构。

Fluid strength torque converter although can stepless change the torque in certain scope compared to, but because it exists changes turns between ability and the efficiency contradiction, at present the application fluid strength torque converter generally changes turns the coefficient insufficiently to be all big, satisfies the automobilism request with difficulty, therefore on the high-quality passenger vehicle, widely uses is fluid strength torque converter and the gear type transmission gearbox union composition fluid strength mechanical type variator.

液力变扭器虽然能在一定范围内无级地改变扭矩比，但由于它存在着变扭能力与效率之间的矛盾，目前应用的液力变扭器一般变扭系数都不够大，难以满足汽车使用要求，故在高级轿车上，广泛采用的是液力变扭器与齿轮式变速器联合组成液力机械式无级变速器。

The annual production of rear axle hyperboloidal gear of autotruck is 150,000 sets .

其中汽车后桥主被动齿轮年生产能力15万套。

And in the case of bevel gears, the rotational axes are not parallel to each other.

在斜齿轮情况下，并且，旋转的轴不是互相平行的。

Mass, size and location of each payload component with respect to the axis of rotation and pinion surface.

相对于旋转轴和齿轮表面的每个负载元件的质量，尺寸和位置

The reason for this, in the case of helical gears, is that the teeth are not parallel to the axis of rotation.

因此，在斜齿轮的情况下，其齿向是不平行于回转轴线的。

Since the teeth are inclined to the axis of rotation, helical gears create an axial thrust.

由于牙齿倾向于向旋转轴，螺旋齿轮创造一个轴向推力。

Because there is a box-hole processing machine tool, gear and other processing error, the tool axis of rotation of the drive space is too large, large amount of so-called open.

因为有一个盒子，孔加工机床，齿轮等加工误差，驱动器的空间旋转刀轴过大，大量的所谓公开的金额。

The axles run in two-row self aligning ball bearings on the gear side, and a standard sealed ball race on the other end in the sprung axle box, both 12mm bore.

两轴运行的排调心方对球轴承齿轮，和一个标准就在轴箱弹簧的另一端密封球的比赛，两个12毫米口径。

Multi-axle box design includes: mapping the original basis for the design of multi-axle box diagram, the spindle diameter and gear modulus determination and power calculation, multi-drive axle box design, drawing more than Axlebox an important component of general layout, as well as the intensity of checking.

多轴箱设计包括：绘制多轴箱设计原始依据图、主轴直径和齿轮模数的确定及动力计算、多轴箱传动设计、绘制多轴箱总图以及重要部件的强度校核。
