GEAR TRAIN Russian patent published in 1997 - IPC

FIELD: mechanical engineering; gearings. SUBSTANCE: gear train for use in disintegrator has driving wheel 1 and driven wheel 3 with wear-resistant material applied to working surfaces of wheels. Material is applied in uniform layer 2 on driven wheel and in form of projecting parts of wear-resistant material 4 on driving wheel. With gear wheels rotating, projecting parts of wear-resistant material on driving wheel, engaging with wear-resistant coating of driven wheel, take up most portion of load. Thanks to it wear of base material of driving wheel is reduced. EFFECT: improved wear resistance of gearing and increased service life. 2 dwg
