The 3D simulation of the reducer is based on the regular polygonal axis distribution and the micro reducer is a series structure. This scheme is easy to serialize, and the layout of each axis is clear and simple. Based on the micro-reducer of the regular hexagonal axis distribution, the center line of the input shaft and the five output shafts are evenly distributed in the hollow cylinder box on each side of the regular hexagon and its extension line, and the angle of each axis is 120b. However, the output ratios of the output shafts are not equal. The design calculates the size of the regular hexagon of the axis distribution, which in turn leads to the size of the box and the positional dimensions of the inner and outer mounting holes. The center points of the inner and outer mounting holes are located on the center line of the corresponding axis. Due to the structural characteristics of the reducer itself, the housing is simple to manufacture and easy to install. The single-stage reduction gear ratio is i=2, 3, 4, 5, and 6, in order.
For the reducer with different gear ratios, the interference between the driving wheel and the driven wheel is a key issue for further research in the future. It can be solved by studying the formula for calculating the size of the reducer. The single-stage reduction gear ratio of each axis is i=10 based on the distribution of the micro-reducer based on the regular pentagon axis. The interference problem between the transmission mechanisms no longer exists, and the structure is more simple and clear. The two types of reducers listed have an overall size in the range of 100 mm, meeting the requirements of small mechanical dimensions.
The micro-reducer based on the distribution of the regular polygonal axis has the following characteristics: each axis is mounted with a regular polygon as the base, and three regular polygons are nested; the types and quantities of the components on each axis are basically the same, the structure is clear, the parts are simple to install, and the appearance is beautiful; The transmission ratio is large. In a small space, the single-stage transmission ratio can reach 20:1 or above; the number of regular polygon sides N satisfies N3; the series transmission ratio can be directly obtained, and N-1 outputs are realized, and the output directions are different; Light weight, small size and few parts; the space curve meshing wheel is simple to manufacture and install, and the cost is low; the transmission is continuous and stable, but limited to small power transmission.
