Problems solved by technology

The flexible spline of the harmonic reducer must not only produce flexible deformation, but also bear a large alternating load. However, the existing flexible spline of the harmonic reducer is usually made of cast iron, and its surface hardness is low, the roughness is large, and it is not resistant to Corrosion, low fatigue strength, can not meet the application needs of the chemical industry

Abstract

The invention discloses a preparation process of a harmonic reducer flexible gear. The preparation process mainly comprises the following steps: (1) a low-carbon alloy steel basal material is molten as alloy soup in inert gas; (2) the alloy soup, prepared in the step (1), is poured in a harmonic reducer flexible gear casting mold for cooling molding, is molded through die-casting extrusion, and is thermally treated and annealed to form a harmonic reducer flexible gear blank; (3) the harmonic reducer flexible gear blank, manufactured by the step (2), is turned and punched as circular pieces; (4) the circular pieces, manufactured by the step (3) are spun at 400-450 DEG C, and are protected by inert gas to manufacture a harmonic reducer flexible gear prototype; and (5) the harmonic reducer flexible gear prototype is finished and polished to remove burrs on the surface; the laser heat treatment is performed for the surface layer to realize carbonitriding; the thickness of a carbonitriding layer is 0.08-0.12 mm; and the finished harmonic reducer flexible gear is manufactured. The manufactured harmonic reducer flexible gear is excellent in wear resistance and high in corrosion resistance and fatigue resistance.

Description

technical field [0001] The invention relates to a harmonic reducer, in particular to a preparation process of a harmonic reducer flex spline. Background technique [0002] The harmonic reducer is composed of a fixed internally toothed rigid wheel, a flex spline, and a harmonic generator that causes radial deformation of the flex spline. It has the advantages of high precision and high bearing capacity. Compared with ordinary reducers, The material used is 50% less, and the volume and weight are reduced by at least 1 / 3. It is widely used in electronics, aerospace, robotics and other industries. Due to its unique advantages, its application in the chemical industry is gradually increasing. The flexible spline of the harmonic reducer must not only produce flexible deformation, but also bear a large alternating load. However, the existing flexible spline of the harmonic reducer is usually made of cast iron, and its surface hardness is low, the roughness is large, and it is not r...
