Micro DC geared motor gearbox
The micro DC geared motor gearbox includes a box body, an output shaft rotated in the box body, an output gear sleeve pressed on the output shaft, and a gear set meshing with the output gear. The gear set includes multiple gears meshing in sequence. Assemblies, a plurality of rotating gear shafts arranged in the box body, each gear assembly is respectively sleeved on a gear shaft, and the two ends of each gear shaft are respectively connected to the box body through oil-impregnated bearings, and the oil-impregnated bearings The gearbox plays the role of lubricating the gear shaft. During the operation of the motor, the gear shaft rotates in the oil-impregnated bearing, which can prevent the phenomenon of seizure and prolong the service life of the whole machine. At the same time, the gear shaft rotates in the oil-impregnated bearing to reduce frictional resistance , thus improving the transmission efficiency and saving energy.
