[摘要]渐开线少齿差传动卷扬机是诸多传动形式卷扬机中的一种。利用少齿差传动机构的优越性可改进和提高建筑机械等设备的传动结构技术性能，将渐开线少齿差行星齿轮传动应用于建筑卷扬机的动力传输系统，可以减小机构尺寸，提高传动质量，同时它的传动比大、承载能力大、寿命长，也降低了制造成本。但是在渐开线少齿差内啮合传动中,由于内齿轮和外齿轮的齿数差少,在切削和装配时常常会产生各种干涉,以致造成报废。因此,为了保证内啮合传动的正常运转,设计时要满足几个条件，主要的两个限制条件是，即要保证不发生齿廓重迭干涉和啮合率不小于1。少齿差内啮合的设计非常烦琐,尤其是齿廓重迭干涉验算最为麻烦，这也是解决设计问题的核心所在。在设计过程中多次变换变位系数和齿顶高系数以满足条件。
本文主要对少齿差行星齿轮传动的设计计算进行了说明。其中包括工作原理、参数选择、几何计算等。并根据结构尺寸设计零件、选择标准件，然后再进行强度或者寿命校核计算。

[Abstract] Involute gear transmission with small tooth number difference hoist is one kind of transmissions forms hoist. It can improve and enhance the transmission structure technical performance of the construction machinery using the of small tooth number difference planetary transmission. If the involute gear transmission with small tooth number difference transmission will apply for construction hoist transfer system, it can increased besides a reduction ingear size, and no interference will occur, and improves the transmission quality simultaneously its velocity ratio is big and the load capacity is big too, the life is long, and it also can reduce the production cost. But in the mesh inside of forma small tooth number difference transmission, because of the difference of annular gear and the external gear is few. It ofter causes interference in the cutting and the assembly, so that it may be waster. Therefore, in order to in guarantee meshes the transmission noramal work, the design must satisfy several conditions. The two main limiting condition is that it must guarantee does not have the tooth outline overlap interference and meshing rate smaller than 1.The design of the mesh inside of forma small tooth number difference is troublesome, extremely the checking computations of the tooth outline overlap difference. It is also the core of the solution in the design. It need to transform the dislodgement coefficient and the gear addendum coefficient many times to satisfy the condition in the design process.
This paper describes the method which is used for designing the drive of the few difference in number of teeth. Including principle of work, parameter choice, geometry computation and so on. Choose the standard letter on the basis of the structure size design components, then carry on the computation of the intensity or the life examination.
