Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
Fig. 1 show the structural schematic diagram of common hobboing cutter, which has isodiametric cutting cutter tooth, this kind of equal diameter knife
Tool can because head number is more, helical pitch is big cause to the worm gear surface of processing cause it is larger transform into error, and worm gear surface is gradually opened
Line is irregular, so as to cause worm gear galloping, generates loud noise.As shown in Fig. 2, being one kind provided by the utility model
The schematic diagram of whole tangential hob, which includes hobboing cutter body 1, the cutting cutter tooth 11 that is connected as one with hobboing cutter body 1 and
The knife bar 2 being connected as one with hobboing cutter body 1, cutting cutter tooth 11 are helical form, and one end of knife bar 2 is equipped with knife bar taper shank portion 21, knife
The other end of bar 2 is equipped with knife bar support portion 22, and cutting cutter tooth 11 includes taper cutter tooth portion 111 and parallel cutter tooth portion 112, taper knife
Teeth portion 111 axially has taper along it and forms small end and big end, the small end in taper cutter tooth portion 111 close to knife bar taper shank portion 21,
The big end in taper cutter tooth portion 111 and parallel 112 integrally connected of cutter tooth portion, cutting cutter tooth 11 are dextrorotation, and appearance is offered on hobboing cutter body 1
