Abstract

The invention discloses an Archimedes helicoid worm gear hobbing and shaving precision detection method. The method comprises the following steps: 1) constructing a tooth surface equation and a tooth surface normal vector equation of an Archimedes worm; 2) constructing a tooth surface equation and a tooth surface normal vector equation of an Archimedes worm gear according to the meshing relationship between the Archimedes worm gear and the Archimedes worm; 3) simplifying the tooth surface equation and the tooth surface normal vector equation of the Archimedes worm gear according to an orthogonal relation between a relative motion velocity vector and a normal vector of the Archimedes worm gear and the Archimedes worm at any contact point; 4) selecting a plurality of grid points on the tooth surface of the worm gear by adopting a dot-matrix measurement method, calculating theoretical coordinates and normal vectors of grid points respectively by utilizing the simplified tooth surface equation and tooth surface normal vector equation of the Archimedes worm gear, and measuring by using a measuring head to obtain measurement coordinates at the grid points; and 5) calculating the machining error of the Archimedes worm gear tooth surface by using the theoretical coordinates, the normal vector and the measurement coordinates of the grid points.

Description

Technical field [0001] The invention belongs to the technical field of mechanical error analysis, and is specifically a method for detecting a spiral surface wheel machining accuracy. Background technique [0002] The worm gear drive is a transmissive type with a compact, high speed ratio, commonly used to deliver motion and power between the two intensive shafts, and is widely used in modern industries. The worm gear is generally used with hobbed machine, mainly with two methods of rolling toothing and flying knife. When manufacturing a precision worm wheel, a refined processing such as shaving, helper or teeth can be performed after rolling tooth or cut teeth. [0003] The tumble is used to cut the toothed shape as the working worm as the working worm, and cut out the toothed shape according to the principle of the exhibition (see gear machining). If the radial feedback roll is used, the hob rock and the workpiece are pulled by Z2 / Z1 (Z1 as the number of working worm threaded...
