Description
Technical field
The present invention relates to actuating unit, refer to a kind of direct connection skew speed reducer particularly.
Background technique
Speed reducer is the device of extensive use in all kinds of machinery, and the quality of Design of Speed Reducer directly affects the transmission performance of machinery.At present, extensive use highi degree of accuracy RV robot retarder, harmonic speed reducer be main, their common features are small volume, big speed ratio, highi degree of accuracy, high moment of torsion.Wherein harmonic wave is relatively simple for structure, but due to the rigidity of flexbile gear not enough, so performance is not good enough in torque transmitting.And the complicated structure of RV retarder, by motor output shaft to input shaft, input shaft is passed to through reducing gear and exports position.
In prior art, the output shaft of motor and the assembly structure complexity of input shaft, repair demolition difficulty, and the various cable putting positions confusions in speed reducer, often because external factor causes cable to use, therefore, need make improvements.
Summary of the invention
Object of the present invention is exactly the deficiency for above-mentioned background technology, provides a kind of structure simple, easy to assembly and the direct connection of cable can be protected to offset speed reducer.
Technological scheme of the present invention is: a kind of direct connection skew speed reducer, comprise the motor and speed reducer be fixedly connected with by adpting flange, it is characterized in that: the output terminal of described motor is set with input gear, the first meshed transmission gear that in described input gear and duplicate gear, diameter is larger, the second gear radial outer periphery that in described duplicate gear, diameter is less is provided with and is symmetrical arranged for a pair and the planet wheel be meshed with it, described planet wheel centrally axle is fixedly set on eccentric shaft, described eccentric shaft is provided with the needle bearing that two have 180 ° of phase differences, two described needle bearing radial outside correspondences are provided with the first cycloid wheel and the second cycloid wheel, described first cycloid wheel and the second cycloid wheel radial outside are provided with gear pin, described gear pin radial outside is provided with output seat, also be fixedly installed a quill shaft in described reducer shell, described quill shaft is provided with through through hole vertically, and described through through-hole wall is provided with its diameter compatible and protective tube for arranging cable, and described duplicate gear is sleeved on protective tube.
Further, two described needle bearings are axially respectively provided with positioning bearing in outside, and described positioning bearing is sleeved on described eccentric shaft.
The present invention is passed to cycloidal-pin wheel reduction gearing mechanism by motor input shaft through duplicate gear and slows down, and it installs simple, and versatility is good, and convenient disassembly, be convenient to safeguard; In addition, in reducer shell, arrange a through protective tube, the various cables in speed reducer can be placed in this protective tube, cable not only can be made to put conditioning in order, can also protect cable, prevent foreign object from causing damage to it.
