Embodiment Construction

[0016] See Figure 1 to Figure 5 , the profile of cutter of the present invention is similar to gear shape cutter (referring to figure 1 ), including the cutter disc 1, which is provided with a circle of cutter teeth 2 which have a conjugate tooth shape with the workpiece gear teeth, and the normal modulus of the double-sided cutting gear cutter of the cylindrical gear and the normal modulus of the workpiece In the same way, each tooth 2 must have an angle suitable for the cutting state, so each tooth 2 has a rake angle γ and an addendum relief angle α e , side edge relief angle α c (see figure 1 , image 3 , image 3 middle r b0 is the radius of the base circle, α is the pressure angle, r is the radius of the indexing circle, N-N is the intersection point k of the side edge of the tooth and the indexing circle and is tangent to the base circle and parallel to the axis of the tooth disc), and Degree circular helix angle, etc.; each tooth 2 also has a side edge rake angle...

Abstract

The invention discloses a double-side edge tooth cutting tool for a cylindrical gear. The double-side edge tooth cutting tool comprises a cutter tooth disc, wherein the cutter tooth disc is provided with a circle of cutter teeth having a conjugated tooth shape with a workpiece gear set; the normal modulus of the double-side edge tooth cutting tool for the cylindrical gear is identical with that of a workpiece; and the cutter teeth comprise a front angle gamma, a tooth top rear angle alpha e, a side-edge rear angle alpha c and a spiral angle. The double-side edge tooth cutting tool is characterized in that each cutter tooth is also provided with a side-edge front angle gamma sc; the side-edge front angle gamma sc is an intersection angle between an intersection line y1g1 of a plane M1-M1 and the front cutter surface of the cutter teeth and the normal plane S-S of the cutter teeth, wherein the plane M1-M1 passes any point y1 on the side edge of the cutter teeth, is tangent to a circle passing the point y1 on the cutter tooth disc and is simultaneously parallel to the axis of the cutter tooth disc; and the inclined directions of the side-edge front angles gamma sc corresponding to the toothed surfaces at two sides of each cutter tooth are opposite and inclined from the side edges of the cutter teeth to the midlines of the cutter teeth and the inside of a cutter body respectively. The double-side edge tooth cutting tool disclosed by the invention has reasonable cutting parameters in the processing process, optimized cutting states and formed favorable cutting precision and surface quality.

Description

technical field [0001] The invention belongs to the field of mechanical processing cutters, and in particular relates to a double-side cutting cutter for cylindrical gear cutting. Background technique [0002] In the field of machining, the processing technology from blank to cylindrical gear tooth profile surface is divided into two types based on generating method and forming method in principle. Currently widely used processing technologies such as gear hobbing, gear shaping, and shaving belong to the generation method, and forming milling and broaching belong to the forming method. According to different processing methods, cylindrical gear processing tools are divided into gear processing tools based on the generation method such as hobbing cutters, gear shaper cutters, and gear shaving cutters, and gear processing tools based on the forming method such as forming milling cutters and broaches. Cutting gear processing belongs to the generating method. The cutting gear p...
