FIELD: mechanical engineering. ^ SUBSTANCE: gear wheel comprises standard parts or standard and nonstandard parts. The engagement angle of the standard parts is chosen to allow the wheel to be changed for, e.g. the standard wheel to be repaired. The values of coefficients of face or total overlapping of the teeth decrease with respect to the nominal coefficients of overlapping. The nonstandard parts are made with an inclination to the thickening of the tooth with respect to the standard shape. ^ EFFECT: prolonged service life. ^ 6 cl, 5 dwg |
