Abstract
The utility model relates to a stepping type motor comprising an upper casing of the motor and a lower casing of the motor. The stepping type motor is characterized in that a boss is arranged on the upper casing of the motor, a first installing hole of a rotating shaft of a rotor is arranged on the boss, the lower casing of the motor is correspondingly provided with a second installing hole of the rotating shaft of the rotor, the rotating shaft of the rotor is installed in the first installing hole and the second installing hole, and the rotor with a gear is arranged on the rotating shaft of the rotor.
Description
Technical field
The utility model relates to a kind of stepper motor.
Background technology
In the prior art, the gear of stepping motor is fixed on the output shaft, output shaft and gear hole interference fit, and this kind structure is higher to the parts processing request, and processing cost is high.
The utility model content
The goal of the invention of the utility model is to provide a kind of stepper motor, is easy to processing, effectively solves the problem that the output shaft and the gear hole magnitude of interference are difficult for assurance.
Realize the technical scheme of the utility model goal of the invention:
A kind of stepper motor; Comprise motor upper shell and motor lower house; It is characterized in that: the motor upper shell is provided with boss, and boss is provided with rotor shaft first installing hole, and the corresponding motor lower house is provided with rotor shaft second installing hole; Rotor shaft is installed in aforementioned first installing hole and second installing hole, and the rotor of band gear is housed on the rotor shaft.
The rotor center position of band gear has through hole, and rotor shaft is contained in this through hole.
The beneficial effect that the utlity model has:
The utility model motor upper shell is provided with boss; Boss is provided with rotor shaft first installing hole; The corresponding motor lower house is provided with rotor shaft second installing hole, and rotor shaft is installed in aforementioned first installing hole and second installing hole, and the rotor of band gear is housed on the rotor shaft.Gear and rotor are integrative-structure, and directly injection molded during installation, only needs to be contained on the armature spindle with the rotor of gear to get final product, and does not need to adjust the magnitude of interference of output shaft and gear hole again, and parts are easy to processing, and assembly technology is simple.
