In other words, an optimal reducer is

3、 generally not an assembly of components optimized in isolation, a fact overlooked by many conventional design heuristics. For instance, the impact of a certain choice of gear width and center distance may yield a minimum mass gearing, but the selection of this gearing may cascade through subsequent

4、 steps of the design process (sizing of shafts, further stages, bearings, housing, etc.) to ultimately lead to a heavier reducer than if a slight compromise had been made on the choice of that first gearing.A typical example might be that selecting a smaller than optimal gear diameter (and a corresp

5、ondingly greater contact width) could yield a somewhat heavier gearing,but a more compact layout and therefore a much lighter housing; it is worth mentioning though that in reality the impact on the overall objective tends to be much less direct and therefore much more obscure than in this example.O

6、f course, in all but a few trivial cases, it is impossible to tell what that first compromise should have been, let alone what any subsequent choices should have been made with the overall goal in mind, instead of concentrating on the subsystem in hand. The chief reasons impeding a truly holistic re

7、asoning at every step of the design heuristic are the sheer number and the highly non-linear nature of the constraints and the objectives, the large number of design variables and the complexity of the interactions between them. Additionally,analytical models may not be available for these interacti

It possesses the merit of involute gear that can be manufactured easily and separately. It also possesses

9、 the feature of high contact strength of arc gear wheel. Thus it has greater power, lower noise, and higher efficiency to bear the weight. Not only has single point-line meshing gear (similar to single arc gear wheel) and double point-line meshing gear (similar to double arc gear wheel) been develop

In this article, the meshing theory, design calculation, sealing graph of the parameter selection, manufacturing, bearing ability test and the example of its applications in various places are introduced.

12、ission can be divided into two types. Type I is the line meshing gear. When they are meshing, the contact curve is a line or an arc line, such as involute or cycloid gear. Because its manufacture technology is simple, the involute gear is widely used in industry, and becomes dominant. But the main a

13、pplication of involute gear is the meshing between convex profiles, where the contact stress is very large and the load capacity is low. Type II is the point meshing ransmission such as circular-arc gear. In the 1950s, circular-arc gear technology was imported from the Soviet Union. Circular-arc gea

14、r consists of two basic components: concave contour and convex contour. The contact curve is a point when meshing, and the curve after loading distortion is a surface meshing. Then the contour stress becomes smaller, and its load capacity becomes larger. But its manufacturing technology is more comp

15、lex, it needs the special hob, and the load capacity will descend when centre distance error exists. The pinion in the point-line meshing gear is a special modified short teeth. The top of the gear wheel is the convex contour of involute, its bottom is the concave contour of the transitional curve. When they are meshing, there exists not only line meshing (the contact curve is a line) but also point meshing (the meshing is between concave and convex contour). So we call th
