The results showed that the drive efficiency of the worm helical gear can be improved a lot, which nearly reach to the level of the worm and wheel drive, presently, this show us a beautiful prospect of the engineering application of the worm helical gear drive.

结果表明，通过斜齿轮的齿廓修形，可以使蜗杆斜齿轮的传动的效率得到提高，接近甚至达到蜗杆蜗轮传动的传动效率，从而为蜗杆斜齿轮传动的工程应用打下了良好的基础。

It is shown that the symmetric arcuate tooth trace cylindrical gear is a type of highly durable and heavy-load gear.

对称弧线圆柱齿轮作为一种高性能重载齿轮，适用于石油、矿山等重型机械，也能够满足各种机械对齿轮高精度、低噪音以及结构紧凑的要求。

Aiming at the fracture in operation of damageable pump shaft used on locomotive, macroscopic and microscopic analysis of the pattern of fractured cross section in pump shaft is conducted and it is recognized that the fracture is typically caused by combined action of bending and torsion fatigue.

针对机车用水泵轴在使用中容易发生断裂的问题，对水泵轴断口的宏观和细观形貌进行了分析，认为断口为典型的弯扭复合疲劳断口。通过检测水泵轴上装配的齿轮，发现由于齿轮的加工误差过大，在轴的退刀槽根部造成了较大的附加拉应力，最终导致轴的断裂。因此及时消除齿轮的加工误差，同时提高安装精度，是防止此类断裂发生的关键

In the generation of a face gear by a shaper, there is the possibility of undercutting in the dedendum area of inner diameter and the pointing of the teeth in the addendun area of outer diameter.

在面齿轮的加工中，面齿轮在内径处易产生根切，而在外径处易产生齿顶变尖现象，因此面齿轮的齿宽受到了限制。

Ifs use finger shape milling cutter or a dish of shape piece of milling cutter adopt single tooth dispart law cutting time, cans process straight teeth, skewed tooth, a garden of stud gear and bring groove double helical gear or worm gear, this moment was processed gear's dentiform then by cutting tool become shape.

若用指形铣刀或盘形片铣刀采用单齿分度法切削时，可加工直齿、斜齿、园柱齿轮及带槽人字齿轮或蜗轮，此时被加工齿轮的齿形则由刀具成形。
