[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] The utility model embodiment discloses an internal gear transmission reduction motor.

[0025] The utility model provides Figure 1-3 An internal gear transmission reduction motor shown includes a gearbox 1, both sides of the gearbox 1 are provided with first through holes, the insides of the two first through holes are respectively rotatably connected with an input shaft 2 and an output shaft 3, one side of the gearbox 1 is fixedly connected with a motor 4, one end of the input shaft 2 is fixedly connected to the output end of the motor 4, a reduction mechanism is arranged between the input shaft 2 and the output shaft 3, a support rod 5 is fixedly connected to the inside of the gearbox 1, a second through hole is provided on the upper surface of the support rod 5, a first rotating rod 6 is rotatably connected to the inside of the second through hole, a fan blade 7 is fixedly sleeved on the rod wall of the first rotating rod 6, a transmission mechanism is arranged between the first rotating rod 6 and the motor 4, the motor 4 drives the first rotating rod 6 to rotate through the transmission mechanism, and heat dissipation holes are arranged on the upper and lower surfaces of the gearbox 1.

[0026] Start the motor 4, and then the first rotating rod 6 can be rotated through the transmission mechanism, and then the first rotating rod 6 drives the fan blades 7 to rotate, and then air can enter from the heat dissipation holes below and be discharged from the heat dissipation holes above, thereby playing a role in heat dissipation, so as to increase the service life of the device.

[0027] In order to achieve the deceleration effect, Figure 1-2 As shown, the reduction mechanism includes two first gears 8, two second gears 9 and a second rotating rod 10. The second rotating rod 10 is rotatably connected to the inside of the gear box 1. The two first gears 8 are respectively fixedly sleeved on the rod walls of the input shaft 2 and the second rotating rod 10. The two second gears 9 are respectively fixedly sleeved on the rod walls of the output shaft 3 and the second rotating rod 10. The two first gears 8 are respectively meshed with the corresponding second gears 9.

[0028] The sizes of the two first gears 8 are both smaller than the size of the second gear 9. Then the motor 4 is started, and the output shaft 3 can be rotated through the transmission of the two first gears 8 and the second gear 9, and the rotation speed is much lower than the rotation of the input shaft 2.

[0029] In order to make the first rotating rod 6 rotate, Figure 1-3 As shown, the transmission mechanism includes two third gears 11, one of which is fixedly sleeved on the rod wall at one end of the input shaft 2, and the other is fixedly sleeved on the rod wall of the first rotating rod 6, and the two third gears 11 are meshed with each other.

[0030] The motor 4 is started. When the input shaft 2 rotates, the first rotating rod 6 can be rotated by the transmission of the two third gears 11. Here, the third gears 11 are all bevel gears.

[0031] To prevent dust from entering, Figure 1-2 As shown, the insides of the two heat dissipation holes are fixedly connected with filter screens 12.

[0032] The two filters 12 can prevent dust from entering the interior of the gear box 1 .

[0033] In order to facilitate the cleaning of the filter screen 12, Figure 1-2 As shown, the lower end of the first rotating rod 6 penetrates the upper surface of the corresponding filter screen 12 and is fixedly connected with a scraper 13 , which matches the corresponding filter screen 12 .

[0034] Because the air moves from bottom to top, the surface of the filter screen 12 below is easily contaminated with dust. At this time, the rotation of the first rotating rod 6 drives the scraper 13 to rotate, so that the scraper 13 can scrape off the dust on the surface of the filter screen 12.

[0035] Finally, in order to facilitate air entry, Figure 1-2 As shown, a plurality of two support blocks 14 are fixedly connected to the lower surface of the gear box 1 .

[0036] The gear box 1 can be raised by using the two support blocks 14 , so that air can easily enter the interior of the gear box 1 .

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
