Planetary hypocycloid speed reducer for carrying welding robot

Abstract

The invention relates to the technical field of speed reducing and provides a planetary hypocycloid speed reducer for a carrying welding robot. The planetary hypocycloid speed reducer comprises a shell body, bearings, an output disk, a bearing seat, a big end cover, a planet and a hypocycloid transmission component. The planetary hypocycloid speed reducer is characterized in that a rigid output cylinder is supported by the bearings in the shell body; the end face of the shell body is connected with the big end cover; the bearing seat is connected in the big end cover; the planet comprises a sun wheel, planet wheels and crank shafts; the planet wheels are connected with the crank shafts; a bearing body is installed on the eccentric shaft head of each crank shaft; a disk is supported by the three bearing bodies; the hypocycloid transmission component comprises a cycloidal wheel and a hypocycloid gear ring; the cycloidal wheel is tightly matched with the excircle of the bearing seat; the hypocycloid gear ring comprises a first hypocycloid gear ring body and a second hypocycloid gear ring body; the first hypocycloid gear ring body is tightly fixed to the risk; the second hypocycloid gear ring body can rotate smaller than 1 degree relative to the first hypocycloid gear ring body; the space between the inner teeth of the hypocycloid gear ring and the teeth of the cycloidal wheel is zero; the big end cover is provided with windows; the inner teeth of the hypocycloid gear ring are obtained by cutting with threads; The planetary hypocycloid speed reducer has the beneficial effects that the return difference can be adjusted; the bearing capacity of a hypocycloid engagement pair is high; when the reduction ratio is equal to 3-4, the first bearing and the second bearing are not too large.

Description
