Problems solved by technology
As a special transmission form of the reducer, the planetary gear reducer is widely used in the transmission system of various industries due to its large load capacity, small size and high efficiency. At present, the standard series of our country (including the P series) planetary gear reducer, the first and second-stage internal ring gears adopt structures with different modules and numbers of teeth, and a transition piece is used to connect the first and second-stage internal ring gears in the middle, thus increasing each At the same time, the cumulative error caused by processing is increased, which will eventually affect the transmission performance of the whole machine

Embodiment
[0008] Embodiment: A structure-improved X-type standard planetary gear reducer with combined ring gear, including the first-stage ring gear 1 and the second-stage ring gear 2, the first and second-stage ring gears 1, 2 One-piece molding structure, which greatly reduces the joint surface of each link, makes the structure more compact, has good process performance, and is beneficial to the heat dissipation of the whole machine and the enhancement of load-sharing performance.
[0009] The modulus and number of teeth of the first and second-stage internal ring gears 1 and 2 are the same, and the structure of the first and second-stage internal ring gears 1 and 2 with the same modulus and the same number of teeth can be processed by a gear shaping machine at one time, which improves the The precision of the inner ring gear reduces the cumulative error of the inner ring gear, improves the processing efficiency, and reduces the cost of processing and assembly.

The invention discloses a conjoined inner gear ring for an X type standard planetary reducer with an improved structure. The conjoined inner gear ring comprises a first-stage inner gear ring and a second-stage inner gear ring, wherein the first-stage inner gear and the second-stage inner gear adopt integral forming structures. According to the conjoined inner gear ring, the first-stage inner gear ring and the second-stage inner gear ring adopt integral forming structures with the same moduli and the same tooth number, so that the structure is compact, the processing property is good, the heat radiation of a whole machine is facilitated, and the uniform load property is enhanced.
Description
technical field [0001] The invention relates to a combined inner ring gear for an X-type standard planetary gear reducer, in particular to a combined inner ring gear for an X-type standard planetary gear reducer with improved structure. Background technique [0002] In recent years, the country has gradually increased its investment in the field of infrastructure construction, metallurgy, electric power, construction machinery, energy and other industries have accelerated the development, and the market demand for reducers in related industries has also gradually expanded. As a special transmission form of the reducer, the planetary gear reducer is widely used in the transmission system of various industries due to its large load capacity, small size and high efficiency. At present, the standard series of our country (including the P series) planetary gear reducer, the first and second-stage internal ring gears adopt structures with different modules and numbers of teeth, an...
