High-precision servo speed reducer gear ring

The utility model discloses a high-precision servo speed reducer gear ring, which comprises a gear ring main body, an additional assembly and a wear-resistant ring, the additional assembly is fixedlyconnected outside the gear ring main body, the additional assembly comprises a reinforcing ring and a reinforcing block, the gear block is arranged outside the gear ring main body, and the wear-resistant ring is arranged inside the gear ring main body. According to the high-precision servo speed reducer gear ring, the length of the gear ring body is increased, the problem that the turning time islong when the servo speed reducer gear ring is produced and machined is well solved, due to the fact that the length of an original gear ring body forge piece 120.8 mm is increased by 10 mm, the totalamount is increased by 5%, outer diameter grinding can be omitted during production and machining, and the production efficiency is improved. Therefore, the turning time is reduced by two thirds, theproduction cost is greatly
