Description

Technical Field

[0001] This utility model relates to the technical field of motors, and in particular to an integrated geared stepper motor. Background Technology

[0002] A stepper motor is an electric motor that converts electrical pulse signals into corresponding angular or linear displacement. For each input pulse signal, the rotor rotates by an angle or moves forward one step. The output angular or linear displacement is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. For example, a stepper motor according to prior art publication CN214850671U includes a coil frame, which includes a winding frame. The winding frame has a winding area for winding the coil, and multiple sets of winding frames are connected by a connecting frame, which is injection molded. However, current stepper motors on the market have low torque, cannot achieve precise control, and most do not have a speed reduction function. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an integrated geared stepper motor with higher output efficiency, higher reliability, higher precision, higher cost performance, and longer service life.

[0004] This utility model discloses an integrated geared stepper motor, comprising a housing, a cover plate, a stepper motor assembly, a support component, and a reduction component. The cover plate is installed at the right end of the housing. The stepper motor assembly is installed inside the housing via the support component, and the reduction component is installed inside the housing on the right side. The output end of the stepper motor assembly is connected to the reduction component. The stepper motor assembly is fixedly installed via the support component. The output shaft of the stepper motor assembly generates power, which is output through the reduction component, enhancing torque. The integrated design allows for more complete gear-to-gear engagement between the motor and the reducer, resulting in higher output efficiency and advantages such as high reliability, high precision, high cost-effectiveness, long lifespan, and good control performance.

[0005] Preferably, the support component includes a mounting plate and a support plate. The mounting plate is installed inside the housing on the left side, and multiple support plates are installed inside the housing. The mounting plate and support plates have mounting holes in the middle. The stepper motor assembly is installed in the middle of the mounting plate and support plates. The mounting plate and support plates support the stepper motor assembly, so that there is a gap between the stepper motor assembly and the housing, which facilitates the heat dissipation of the stepper motor assembly.

[0006] Preferably, the reduction component includes a small output gear, two support blocks, a primary shaft, a primary large gear, a primary small gear, a secondary shaft, a secondary small gear, a secondary large gear, and an output assembly. The two support blocks are symmetrically installed on the upper and lower sides of the rear end of the housing. The primary shaft is rotatably mounted on the support blocks, with its left and right ends rotatably mounted between a support plate and a cover plate, respectively. The small output gear is mounted on the output shaft of the stepper motor assembly. The left and right ends of the secondary shaft are rotatably mounted between the support plate and the cover plate, respectively. A secondary large gear is coaxially mounted on the outer wall of the secondary shaft, meshing with the primary large gear. A primary small gear is coaxially mounted on the right side of the primary large gear, meshing with the secondary large gear. A secondary small gear is also mounted on the right side of the secondary large gear. The stepper motor assembly outputs power to drive the small output gear to rotate. The small output gear drives the primary large gear to rotate the primary shaft. The primary shaft drives the secondary large gear to rotate via the primary small gear. The secondary large gear drives the secondary shaft to rotate, and the secondary shaft outputs power via the secondary small gear.

[0007] Preferably, the output assembly includes a support base, an output gear, and an output shaft. The support base is installed in the middle of the cover plate, and the output shaft is rotatably installed in the middle of the support base. An output gear is installed on the left side wall of the output shaft, and the output gear meshes with a secondary pinion. A positioning clearance hole matching the output shaft of the stepper motor assembly is provided on the left end of the output shaft. The secondary pinion drives the output gear to rotate, causing the output shaft to rotate and output power. A groove is provided on the output shaft to facilitate connection with the equipment and avoid slippage.

[0008] Preferably, there are two primary gears: a primary large gear, a primary small gear, a secondary shaft, a secondary small gear, and a secondary large gear. The two primary shafts are diagonally arranged, and the two secondary shafts are symmetrically arranged. The primary large gear and the primary small gear are mounted on the outer wall of the primary shaft, and the secondary small gear and the secondary large gear are mounted on the outer wall of the secondary shaft. Both secondary small gears mesh with the output gear. The output gear drives the two primary shafts to rotate through the primary large gear. The primary shafts drive the primary small gear to rotate. The primary small gear drives the secondary shaft to rotate through the secondary large gear. The secondary shaft drives the secondary small gear to rotate. The two secondary small gears synchronously drive the output gear to rotate, so that the output gear drives the output shaft to rotate and transmit power. The diagonally distributed secondary small gears can ensure stable power output and improve service life.

[0009] Preferably, it also includes two connecting ears and a connecting seat. The two connecting ears are symmetrically distributed and installed on the outer wall of the cover plate. The connecting ears are provided with connecting holes. The connecting seat is installed on the bottom of the housing. The connecting seat has a connector for connecting to the stepper motor assembly. The connecting ears facilitate the installation and fixation of the housing and are convenient to use. The connector in the connecting seat can be connected to the controller via a data cable to control the operation of the stepper motor assembly, resulting in good control performance.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the stepper motor assembly is fixedly installed by the support component, the output shaft of the stepper motor assembly generates power, and the power is output through the reduction component, which enhances the torque. The integrated design makes the gear-to-gear engagement between the motor and the reducer more complete, thus making the product output efficiency higher. This gives the stepper motor advantages such as high reliability, high precision, high cost performance, long life and good control performance. Attached Figure Description
