| PURPOSE:To increase the extent of transfer torque without requiring any grinding operation by setting the strength of material so as to make the side of a worm increase in abrasion loss relatively, and forming each of irregularities and chemical conversion treatment coatings on each tooth surface of the worm and a worm wheel. CONSTITUTION:A worm reduction gear is made up of a combination of relatively hard materials between a worm 2 consisting of cast iron or steel and a worm wheel 4 consisting of cast iron. In this case, a contact surface 7 of the worm wheel 4 is machined in the tooth trace direction U, and irregularities consisting of a crest C and a root diameter D are formed in the tooth depth direction V. In addition, the contact surface 7 is machined, and a tip point of the crest C is rounded, while a chemical conversion coating film F takes place after forming the crest C and the root diameter D are formed in the tooth trace direction as well. On the other hand, likewise as the abovementioned, the irregularities consisting of the crest C and root diameter D and the chemical conversion coating film F are applied to a tooth surface of the worm 2 as well. Then, each material of the worm 2 and the worm wheel 4 is selected so as to make a side of the worm 2 increase in abrasion loss of the tooth surface relatively. | ||||||

| PURPOSE:To form the cutting edges with high precision by setting the center line of the hob to be a tangent line of the base cylinder for the involute curves to form cutting edges and to be parallel to the slopes of the helical grooves and by feed-shifting following the helical grooves in the direction parallel to the rotation of the cutter. CONSTITUTION:In the state in which the contact points of a hob 11, with a lead equal to the interval of the points where an arbitrary tangent line T to a base circle D of involute curves I intersects each involute curve I, and the slopes of helical grooves of a cutter 3 are made to coincide with the tangent line T, cutting edges 2 are notched successively. The slopes of helical grooves of the cutter 3 are not perpendicular to its center line O, and so the center line of the hob 11 is in parallel with the slopes being tangent to the base cylinder D. After setting the position of a hob head 25 to go up and down with respect to a column 24 and the position of the column 24 to turn with respect to a saddle 23, when the motor is operated, the cutter 3 rotates and the hob 11 also rotates simultaneously with this cutter and moves following grooves 1; thus a cutting edge 2 is formed on the slope of the groove. | ||||||

| The invention relates to a method for determining the profile of a substantially involute worm grinding wheel used for generation grinding of helical tooth gear wheels in a continuous diagonal generation method, wherein the axle distance of the worm grinding wheel to the gear wheel changes to create crowning and the engagement angle of the worm grinding wheel changes over the length thereof to eliminate process-caused interlacing and for creating specific interlacing. According to the invention, the continuously running generation grinding method replicates (simulates) based on the penetration principle in a first iteration method, the grinding movement being broken into a plurality of discrete method steps, wherein a section curve is formed by intersecting the sleeve body of the worm grinding wheel with the flanks of the gearwheel and the resulting cut on the tooth flank is determined by calculation and the profile of the worm grinding wheel or a dresser is adjusted to eliminate the calculated cut in a second, subsequent iteration method. | ||||||
