<p>A rigid internally and peripherally meshed speed reducer comprising a first-level speed-reducing mechanism and a second-level speed-reducing mechanism. The first-level speed-reducing mechanism comprises: an eccentric wheel (101); a first rotary arm bearing (5); a peripherally meshing curved wheel (7); and a wheel pin (8), which is fixed onto a first supporting frame (9) and is peripherally meshed with the peripherally meshing curved wheel (7). The second-level speed-reducing mechanism comprises: an eccentric transmission wheel (14); a second rotary arm bearing (13); an internally meshing curved wheel (11), which is internally meshed and fitted with the wheel pin (8); and, an output disk (16), which is linkedly connected to an output shaft (20). The eccentric transmission wheel (14) is transmissively connected to the peripherally meshing curved wheel (7) via a dowel pin (26). The internally meshing curved wheel (11) is transmissively connected to the output disk (16) via a drive pin (24). A first reinforced frame (6) is arranged at one side of the peripherally meshing curved wheel (7), while a second reinforced frame (23) is arranged at one side of the internally meshing curved wheel (11). The speed reducer has the advantages of a reduced number of teeth, large speed ratio, compact size, high loading capacity, high efficiency, and extended service life, and is particularly applicable as a speed reducer for use in a load-carrying robot.</p> |
