Novel wear-resistant driving gear

The utility model relates to the technical field of driving gears, in particular to a novel abrasion-resistant driving gear which comprises a gear ring, evenly-distributed teeth are fixedly connected to the outer side of the gear ring, a ceramic shell is arranged on the outer sides of the teeth, and limiting grooves are formed in the sides, away from the gear ring, of the teeth. The teeth are tightly attached to the tensioning sleeve through the formed limiting grooves, a limiting strip is tightly attached to the interior of the tensioning sleeve, one side of the limiting strip is fixedly connected with the ceramic shell, positioning strips are fixedly connected to the two sides of the interior of the ceramic shell, sliding grooves are formed in the two sides of the teeth, and the positioning strips are arranged in the sliding grooves formed in the teeth. According to the gear, through the arrangement of the teeth, the ceramic shell, the limiting strips, the limiting grooves, the tensioning sleeve, the slidin
