It is identical.
Further, including following technique: the structure of plate-like topping gear chamfering knife is made into grinding wheel material by e., then can be at
For grinding wheel chamfering edge tool, there is same good cutting effect.
F. process to lathe without particular/special requirement, it is easy to operate, after the axial spacing of gear of adjusting and be chamfered, only
Axial microfeed need to be imposed during rotation, rotate for several weeks and chamfered edge processing can be completed.
Plate-like topping gear chamfering knife process principle
The process principle of plate-like topping gear chamfering knife is similar to gear honing, and the filing that cutting process is similar to file is processed.
The axis of chamfering edge tool is parallel with the axis of part to be processed gear.In cutter and Meshing Process of Spur Gear, using between its flank of tooth
Opposite sliding and axial feed pressure carry out the machining of seamed edge.Process is to lathe without particular/special requirement, easy to operate, tune
It is whole to get well and be chamfered after the axial spacing of gear, axial microfeed only need to be imposed during rotation, rotated for several weeks
Chamfered edge processing is completed, plate-like topping gear chamfering knife is that cutting process is not required to cool down, it compressed air can be used to carry out air-cooled,
Main function is the iron filings removed on topping face with piece surface, is conducive to topping face and persistently cuts.
The structure of plate-like topping gear chamfering knife designs
Plate-like topping gear chamfering knife structure is as shown in Fig. 1 ~ 3.Two seamed edges of the same gear teeth of gear processed are two
Forming V-shape cutting face, each section in cutting face are the involute flanks formed by same basic circle, and two flank of tooth are similar to left-handed respectively
With the flank of tooth of dextrorotation cylindric spiral gear.
Whether to spur gear or tooth profile of helical gear chamfered edge, the tooth form modulus and the modulus for the gear that is chamfered of chamfering edge tool are
It is identical, it may be assumed that m knife=m tooth.
To straight-tooth or helical gears chamfered edge, the V-arrangement cutting face angle of chamfering edge tool is different.Straight tooth column tooth processed
When the flank profil seamed edge of wheel, any two cutting face of chamfering edge tool is symmetrical.It is fallen when the flank profil seamed edge of helical gears processed
