Problems solved by technology

Since gear cutting is a brand-new cylindrical gear processing method, there is no related technology and method for the design of gear cutting tools. The movement of gear machining is completely different from the cutting method, which leads to the poor cutting state of the tool designed in this way, low machining efficiency, shortened machine tool and tool life, limited machining range, and affected machining accuracy

Embodiment Construction

[0017] 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 ring of cutter teeth 2 having a conjugate tooth shape with the workpiece gear teeth, and the normal modulus of the cylindrical gear unilateral cutting tool 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 (see image 3 ), flank relief angle α c (see Figure 5 , r in the figure b0 is the radius of the base circle, r is the radius of the indexing circle, α is the pressure angle, N-N is a straight line passing through the intersection point k of the side edge of the tooth and the indexing circle and tangent to the base circle, parallel to the sectional plane of the tooth disc axis), Index circle helix angle, etc., each tooth 2 also has a side edge...

Abstract

The invention discloses a single-side edge tooth cutting tool for a cylindrical gear. The edge tooth cutting tool for a cylindrical gear 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 single-side edge tooth cutting tool for the cylindrical gear is identical with that of a workpiece; 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; 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 gy of a plane M-M of and a front cutter surface of the cutter teeth and a normal plane S-S of the cutter tooth disc, wherein the plane M-M passes any point y on the side edge of a cutter outline of the cutter teeth, is perpendicular to a midline o-o of a front cutter surface of the cutter teeth and is parallel to the axis of the cutter tooth disc; and the inclined directions of the side-edge front angles gamma sc on two adjacent cutter teeth are symmetrically distributed with the midlines of the two cutter teeth as the axes. The single-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 single-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...
