Abstract
The utility model relates to a knife tool for the chamfering of an oblique gear, particularly a knife tool for the bilateral chamfering of an oblique gear. The utility model has the technical proposal that the utility model is composed of two knife blades (3, 5), and a knife body (4), wherein, the knife blades (3, 5) are fixed to the knife body (4). The teeth surface at one side of the knife blade is a straight teeth surface which has the same transverse module and the transverse pressure angle with the oblique gear, the other side of the knife blade is an oblique teeth surface, and a cyclotomic helical angle is appreciably bigger than the helical angle of a work piece. Adopting the utility model, the straight teeth surface can make chamfering for the sharp edge of the oblique gear, and the oblique teeth surface can make chamfering for the root edge of the oblique gear. The utility model has the characteristics of reasonable structure, easy use, high production efficiency, long service life of the knife tool, etc. The utility model can simultaneously make chamfering for the root edge and the sharp edge of the oblique gear, and thus the utility model solves the problems of impact and noise generated by that the root edge of the oblique gear is knocked.
Description
Affiliated technical field:
The utility model relates to and a kind of helical gear is carried out the cutter of chamfered edge, particularly helical gear is carried out bilateral chamfering tool.
Background technology:
At present, the cutter of helical gear chamfered edge is had only monolateral chamfered edge cutter, promptly the helical gear sharp edge is carried out the cutter of chamfered edge.This cutter is made up of cutter hub, two blades, copper sheathing, screws, two insert design become modulus, cutter tooth that pressure angle is identical with pressure angle with the helical gear transverse module, the copper sheathing of chamfered edge cutter is fixed on the cutter shaft, and is moving by gear driven chamfered edge swivel, thereby finishes the chamfered edge to the helical gear sharp edge.But, suffer the collision of harder objuct body when helical gear root face after, also can produce burr and swing to the flank of tooth, thereby when gears engaged, produce impact and noise problem; And monolateral chamfered edge cutter can not carry out chamfered edge to helical gear root face, also just can not solve the problem of being collided with and then being produced by the helical gear root face.
The utility model content:
The utility model purpose provides the bilateral chamfering tool of a kind of helical gear, can not only carry out chamfered edge to the helical gear sharp edge, and can carry out chamfered edge to the helical gear root face simultaneously, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is: form the utility model by two blades, cutter hubs, blade is fixed on the cutter hub, blade one lateral tooth flank is and helical gear transverse module, straight-sided flank that transverse pressure angle is identical, and the blade opposite side is a pitch face, and its cyclotomy helical angle is bigger than normal than workpiece helical angle.
Adopt the utility model, straight-sided flank is to helical gear sharp edge chamfered edge, and pitch face can be determined the number of teeth of cutter according to the centre-to-centre spacing of lathe and workpiece to helical gear root face chamfered edge, according to the chamfered edge height of Principles of Gear Connection and workpiece root face and sharp edge, calculate tooth depth, the transverse tooth thickness of cutter then.For the helical gear that some little modulus, whole depth are big, workpiece cyclotomy helical angle is bigger, employing solves the method for designing that cutter removes the part cutter tooth.For example: if workpiece is the odd number tooth, then Tool Design becomes the even number tooth, even number serrated knife tool can be removed a tooth every a tooth.
The utlity model has rational in infrastructure, easy to use, production efficiency is high, cutter uses characteristics such as longevity, simultaneously to helical gear root face, sharp edge chamfered edge, is produced impact and noise problem thereby solve by the helical gear root face back of being collided with.
Description of drawings:
Accompanying drawing is a structural representation among the utility model embodiment.
Among the figure: screw 1, spring washer 2, left blade 3, cutter hub 4, right blade 5, copper sheathing 6.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, the utility model is formed the utility model by screw 1, spring washer 2, left blade 3, cutter hub 4, right blade 5, copper sheathing 6, left side blade 3 and right blade 4 are fastened on the cutter hub 4 by screw 1 and spring washer 2, and copper sheathing 6 is embedded in the endoporus of cutter hub 4 by interference fit.Bilateral chamfered edge cutter blade one lateral tooth flank is and helical gear transverse module, straight-sided flank that transverse pressure angle is identical, and the blade opposite side is a pitch face, and its cyclotomy helical angle is bigger than normal than workpiece helical angle.In the processing work process, bilateral chamfered edge cutter copper sheathing is fixed on the cutter shaft, workpiece is clamped on the main shaft of lathe, the workpiece centre height is consistent with the center cutter height, radial feed chamfered edge cutter, make the cutter tooth of chamfered edge cutter enter into the teeth groove of workpiece, drive the chamfered edge cutter by workpiece cutter tooth and gear are meshing with each other; If helical gear root face and sharp edge chamfered edge height are undesirable, can adjust the centre-to-centre spacing of workpiece and chamfered edge cutter or unclamp the chamfered edge height that the screw turns blade is adjusted root face and sharp edge, thereby finish helical gear bilateral chamfered edge.
Claims (3)
1, the bilateral chamfering tool of a kind of helical gear, have blade (3,5), cutter hub (4), blade (3,5) is fixed on the cutter hub (4), it is characterized in that blade (3, a 5) lateral tooth flank for helical gear transverse module, straight-sided flank that transverse pressure angle is identical, and the blade opposite side is a pitch face, and its cyclotomy helical angle is bigger than normal than workpiece helical angle.
2, according to the bilateral chamfering tool of the described helical gear of claim 1, also have copper sheathing (6) in it is characterized in that forming, copper sheathing (6) is embedded in the endoporus of cutter hub (4) by interference fit.
3, according to claim 1 or the 2 described bilateral chamfering tools of helical gear, also have screw (1), spring washer (2) in it is characterized in that forming, left blade (3) and right blade (4) are fastened on the cutter hub (4) by screw (1) and spring washer (2).
