The construction and manufacture of non-circular gears is one of the most difficult issues in
machine technology. Due to the limited technological capabilities of traditional machines …

In this paper, the authors present the design of a suitable gear transmission with the
continuously changing gear ratio in the range from 0.5 through 1.0 to 2.0 and back during …

Current research of non-circular gear processing mainly focuses on gear hobbing. However,
this method has many limitations including being unable to process internal gears or non …

Indexing mechanism is one of the most important mechanisms in automated machineries.
Various kinds of indexing mechanisms have found existence in application, including cam …

In view of the disadvantages of the current grinding method for profile modified spur face-
gear, a progressive grinding method is developed. The third action principle of modified spur …

Face-milling cutting method, widely used in the generation of spiral bevel gear, can also be
applied to cylindrical gear fabrication. This paper, generalizing the method to non-circular …

非圆齿轮最早可追溯到14 世纪左右, 如今已有700 多年历史. 然而非圆齿轮的研究历史却并不
那么久远, 受限于非圆齿轮特殊的几何特性及落后的工业技术水平, 非圆齿轮在过去一直未被 …

One of the main disadvantages of gear mechanisms is the occurrence of noise and
vibrations. This study investigated the applicability of non-circular gears for preventing …

Large flow ripples restrict the development and application of high-order elliptical gear
pumps badly. A new approach is proposed to reduce the flow fluctuations effectively by …

Currently, researches on planar gears (including cylindrical gear, noncircular gear) are
primarily concerned with those of fixed center distance, that is, the center distance between …
