The three-ring speed reducer is characterized in that three identical internal tooth ring plates drive an external tooth gear to output, so that the three-ring speed reducer is called as a three-ring speed reducer, belongs to a parallel shaft and one-shaft gear transmission speed reducer, and gear meshing motion belongs to a shaft gear train, has the characteristic of planetary transmission with small tooth difference, is arranged between an output shaft and an input shaft in parallel, and has the characteristic of a parallel shaft cylindrical gear speed reducer.

The traditional flexible transmission device three-ring speed reducer is connected with the main speed reducer by adopting an expansion sleeve, and when the torque is increased due to abnormal reasons, the expansion sleeve slips, thereby playing a role in mechanical protection. However, in the actual use process, the fault rate of the two matched front-stage three-ring speed reducers is extremely high, the service life is only about one year, and the damage is an internal bearing. In normal operation, the shaft sleeve is often slipped, the shaft and the shaft sleeve are adhered together for a long time, a damaged speed reducer cannot be removed, the shaft sleeve at the expansion sleeve part is required to be removed at the moment, if the shaft sleeve is adhered on the side of the main speed reducer, the speed reducer is required to be disassembled on site, the shaft sleeve on the inner side is required to be removed, and the maintenance time is extremely long, and generally 24 hours are required. According to analysis, the damage of the three-ring speed reducer is caused by small bearing selection, however, due to the compact structure of the three-ring speed reducer, the type of the bearing cannot be changed, only the bearing with better quality and brand can be selected for replacement, meanwhile, the shaft and the shaft sleeve are intended to be improved, the radial transmission torque of the expansion sleeve is changed into the transmission torque of an end cross block, the mechanical protection is cancelled, and the electric setting system is used for protecting the expansion sleeve.
