Description

Technical Field

[0002] Geared motors are power devices that integrate electric motors and speed reduction devices. They drive mechanical systems by reducing speed and increasing torque. The core components are various types of motors and speed reducers, and they are widely used in industrial equipment, automation, home appliances, and automobiles.

[0003] 1. In existing technologies, some geared motors experience significant wear during operation due to poor internal lubrication and insufficient internal rotating connecting parts. Prolonged use can lead to internal malfunctions in the geared motor.

[0004] 2. In existing technologies, some speed reduction devices attract dust during operation due to factors such as electrostatic effects, airflow, changes in heat and humidity, material properties, and environmental factors. Dust accumulation on the surface hinders heat dissipation, leading to overheating; dust entering the gearbox contaminates the lubricating oil, accelerating wear; and dust adhering to the windings reduces insulation, potentially causing short circuits, increases frictional resistance in moving parts, raising energy consumption, and may corrode sealing structures. All of these factors are detrimental to the long-term use of the speed reduction motor. Utility Model Content

[0027] Reference Figure 1-4 This utility model embodiment discloses a low-wear dustproof geared motor, which includes a mounting base 1, a dustproof device 2 disposed on the top of the mounting base 1, a drive motor 3 fixedly connected to the rear of the mounting base 1, and a reduction device 4 disposed in front of the mounting base 1. The dustproof device 2 includes a frame 21, dustproof nets 22 fixedly connected around the frame 21, a fixing block 23 fixedly connected to the front of the front dustproof net 22, a stabilizing bearing 24 disposed in the middle of the fixing block 23, a fan 25 fixedly connected to the middle of the left dustproof net 22, a fan 25 fixedly connected to the middle of the right dustproof net 22, and a first mounting block 26 fixedly connected to the four lower corners of the frame 21.

[0028] The above structure, by being equipped with a dustproof net 22, is able to block external dust during operation.

[0029] By incorporating a fan 25 that blows air outwards, the air inside the frame 21 is propelled to the outside, thus preventing dust from entering the working environment of the drive motor 3 and the reduction gear 4 during the deceleration process. A stabilizing bearing 24, with its inner ring fixedly connected to the output rod 414, provides support for the rotation of the output rod 414 and prevents excessive friction between the output rod 414 and the fixed block 23.

The inner ring of the front first bearing 44 is fixedly connected to the input rod 42, and the outer ring of the front first bearing 44 is fixedly connected to the first bracket 45. The inner ring of the rear second bearing 48 is fixedly connected to the auxiliary rod 47, and the outer ring of the rear second bearing 48 is fixedly connected to the housing 41. The inner ring of the front second bearing 48 is fixedly connected to the auxiliary rod 47, and the outer ring of the front second bearing 48 is fixedly connected to the second bracket 49. A second drive gear 410 is fixedly connected to the front of the auxiliary rod 47. A third bearing 411 is fixedly connected to the front and rear sides of the auxiliary rod 47. A third bracket 412 is fixedly connected to the upper part of the inside of the housing 41. A second driven gear 413 meshes below the driven gear 410. An output rod 414 is fixedly connected to the middle of the second driven gear 413. Fourth bearings 415 are fixedly connected to the front and rear sides of the output rod 414. A fourth bracket 416 is fixedly connected to the middle of the housing 41. The inner ring of the third bearing 411 is fixedly connected to the auxiliary rod 47, and the outer ring of the third bearing 411 is fixedly connected to the third bracket 412. The inner ring of the fourth bearing 415 is fixedly connected to the output rod 414. The outer ring of the fourth bearing 415 at the rear is fixedly connected to the fourth bracket 416, and the outer ring of the fourth bearing 415 in the middle is fixedly connected to the fourth bracket 416. The fourth bearing at the front... The outer ring of 415 is fixedly connected to the housing 41. The four lower corners of the housing 41 are fixedly connected to the second mounting block 417. The oil change pipe 418 is installed at the bottom of the housing 41. The front of the housing 41 is fixedly connected to the first dust cover 419. The rear of the housing 41 is fixedly connected to the second dust cover 420. The top of the housing 41 is threadedly connected to the cover 421. The right side of the housing 41 is provided with an observation window 422. The input rod 42 is rotatably connected to the second dust cover 420. The input rod 42 is fixedly connected to the output end of the drive motor 3. The output rod 414 is rotatably connected to the first dust cover 419.

[0031] The above structure, by providing a first bearing 44, can protect the input rod 42 from wear during rotation, thus preventing excessive wear of the input rod 42 during operation.

[0032] By providing a second bearing 48 and a third bearing 411, the rotation of the auxiliary rod 47 is protected from wear, thus preventing excessive wear of the auxiliary rod 47 during operation.

[0034] The cover 421 allows the operator to add lubricating oil to the inside of the housing 41 after opening the cover 421.

[0035] By incorporating a first driving gear 43, with a first driven gear 46 meshing above it, and the first driving gear 43 having fewer teeth than the first driven gear 46, the first driven gear 46 initially reduces speed and increases torque under the drive of the first driving gear 43. Furthermore, the first driven gear 46 and the second driving gear 410 are located above the same auxiliary rod 47, ensuring that the axial rotational speed of the second driving gear 410 is the same as that of the first driven gear 46. A second driven gear 413 meshes below the second driving gear 410, allowing the second driven gear 413 to undergo a second reduction in speed and increase in torque under the drive of the second driving gear 410. In other words, the rotation of the output rod 414 is reduced twice.

[0036] By providing a first dust cover 419 and a second dust cover 420, dust can be prevented from entering the rear first bearing 44, the rear second bearing 48 and the front fourth bearing 415.

[0037] Working principle: When using this low-wear dustproof geared motor, first turn on the drive motor 3, then add lubricating oil to the inside of the housing 41 and observe through the observation window 422 to keep the lubricating oil at a good level. Then install the dustproof device 2 on the outside of the drive motor 3 and the gear reduction device 4, and then turn on the drive motor 3 and the fan 25 to start using it.

[0038] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
