The invention relates to a large-bearing-capacity external drive type oscillating tooth cycloid speed reduction and change hub, which is characterized in that a cycloid speed reduction device is used for replacing an original planetary gear for speed reduction, and then a cycloid gear is applied to a speed reduction and change device and is arranged in the hub, so that the control precision of the hub is improved; secondly, the peripheries of the cycloidal teeth of the cycloidal speed reducer are directly used as output ends to drive the hub to rotate, so that the hub can be connected with a tire or is additionally coated with an outer film to form the wheel, the structure is simplified, when the input shaft rotates, the cycloidal gears eccentrically arranged on the input shaft also eccentrically rotate, and as the eccentric directions of the adjacent eccentric parts are opposite, the eccentric parts can rotate eccentrically; therefore, the problem that a single cycloidal gear is unstable during working in the prior art is solved, the cycloidal gear is vertically symmetrical, dynamic balance correction is directly formed on the action of the cycloidal gear, the transmission stability is improved, and compact hub transmission can also be achieved under a transmission structure with a large transmission ratio, high bearing capacity and high precision.
本发明涉及一种大承载力外驱式活齿摆线减变速轮毂,该轮毂通过将摆线减速装置代替原本的行星齿轮减速,进而将摆线轮应用于减变速装置并内置于轮毂内部,提高轮毂的控制精度,其次将摆线减速装置的摆线齿的外周直接作为输出端带动轮毂转动,使轮毂可连接轮胎或另覆外膜形成车轮,精简结构,当输入轴转动时,输入轴上偏心设置的多个摆线轮也将偏心转动,由于相邻的偏心部之间偏心方向相反,进而解决了以往单个摆线轮工作时不平稳的问题,使其上下对称,对其动作直接形成动平衡矫正,提高传动稳定性,使其能在大传动比、高承载、高精度的传动结构下也能实现紧凑的轮毂传动。
