The utility model relates to the technical field of sealing structures, in particular to a combined sealing structure and a speed reducer, and the combined sealing structure comprises a sealing ring main body which is arranged between two structures in sealing fit and is positioned in a mounting groove on one surface of the two structures; and the sealing ring gaskets are mounted between the sealing ring main body and the side walls of the two sides of the mounting groove respectively, and are used for separating the sealing ring main body from the side walls of the mounting groove. By using the sealing ring gasket, a gap is formed between the sealing ring main body playing a sealing role and the right-angle position where the sealing ring main body is easily damaged, the sealing ring gasket can be made of the same material as the sealing ring main body or can be made of a material different from the sealing ring main body, and only proper flexibility of the sealing ring gasket needs to be guaranteed.
