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.
