Description

Technical Field

[0001] The utility model relates to the technical field of stepper motor matching reducer equipment, in particular to a stepper motor matching reducer. Background Art

[0002] The reducer used in conjunction with the stepper motor is generally a planetary gear reducer. During installation and use, the stepper motor needs to be installed on one side of the end face of the planetary gear reducer so that the output shaft of the stepper motor is dynamically connected to the input shaft of the planetary gear reducer. The disadvantage of the existing reducer is that when installing the stepper motor, the tool can only be inserted through a small hole, and the output shaft of the stepper motor is connected to the input shaft of the planetary gear reducer through a coupling, and the locking coupling cannot be installed in multiple directions. In addition, the threaded hole on the coupling is pre-processed. After the thread of the threaded hole fails, the coupling can only be replaced, and the cost of use is relatively high.
