A kind of eccentric input hollow planetary reducer, comprises input shaft, input shaft gear, output shaft, sun gear and reducer shell, also comprises the break output gear shaft and rotary transformer output gear shaft that drive respectively by sun gear engagement.
Further, described output shaft is set to the hollow structure that can hold the guide line such as cable, optical cable.
Further, described sun gear is the different dual gear of modulus, among described dual gear, arbitrary gear engages with input shaft gear, break output gear shaft and rotary transformer output gear shaft respectively, and among described dual gear, another gear is connected with planetary mechanism.
Further, described output shaft is arranged on reducer shell center, and described input shaft, break output gear shaft and rotary transformer output gear shaft equal angles scattering device are circumferentially outward extending at output shaft axis.
Further, described input shaft, output shaft, break output gear shaft and rotary transformer output gear shaft be arranged in parallel.
The beneficial effects of the utility model are:
The utility model is by eccentric setting input shaft and output shaft and engaged by sun gear and drive break output gear shaft and rotary transformer output gear shaft, an input can be realized, three outputs, simultaneously mounted motor, break, encoder (rotary transformer); By parallel axes and equal angles decentralized design, make stable drive, noise is little, and data feedback is accurate; By output shaft hollow design, cable, optical cable can be worn, hidden placement is carried out to various guide line; avoid taking the useful space, manipulator boundary dimension can be reduced, and then alleviate the weight of whole transmission device; meanwhile, the protection of elastic cable paper and the accuracy of data transmission is also conducive to.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by specification below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
