GEAR WHEEL Russian patent published in 2018 - IPC F16H55/12 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering and can be used in gears lubricated with solid lubricants in powdery dispersed phase. Gear wheel contains a body in form of a disk and a toothed crown with teeth. At both ends of the teeth, a pair of ring linings is reinforced. Length of lateral surfaces of teeth is equal to length of working sections of lateral surfaces of teeth calculated for this wheel. According to the outer perimeter of the body in the region of the bases of the crown rims, along the entire width of the body, radially oriented cutouts are made. Lateral surfaces of cutouts oriented radially are interfaced with lateral surfaces of teeth, and the bottom surfaces of the notches are oriented perpendicular to the ends of the body.

EFFECT: it is ensured that the powdery lubricant is not accumulated and compacted in the region of the bases of the crown rims.
