Description
Technical field
The utility model belongs to machining tool technical field, is related to a kind of hobboing cutter, more particularly to a kind of alloy gear
Hobboing cutter.
Background technology
Alloy gear hob is a kind of conventional gear cutting tool, and a kind of continuous cutting cutter of multiple-cutting-edge.At present
Traditional alloy gear hob, including cutter shaft and circumferentially distributed multiple cutters tooth in cutter shaft, are formed between adjacent cutter tooth
There is chip pocket.Although existing alloy gear hob production efficiency is higher, due to cutter tooth negligible amounts, its work effect is limited
The further raising of rate.But will necessarily only weaken simply by the slot number of increase cutter, the intensity of cutter tooth, influence alloy
The service life of gear hob.If meeting that cutter has the more number of teeth and necessary intensity simultaneously, need to increase cutter
External diameter.But because the increase of cutter external diameter can cause the increase of a large amount of valuable raw material, cutter material cost is improved, while can carry
The high requirement to gear hobbing lathe, increase the production cost of gear.
The content of the invention
The purpose of this utility model is to be directed to the above-mentioned problems in the prior art, there is provided one kind is easy to process and made
With the alloy gear hob that the life-span is longer.
The purpose of this utility model can be realized by following technical proposal：A kind of alloy gear hob, including cutter hub and
With the cutter shaft of cutter hub interference fit, the center of the cutter shaft offers axis hole, is circumferentially uniformly distributed with described cutter hub
Some circle cutting tooths, form chip pocket between described every adjacent two cutting tooth, it is characterised in that the knife back of the cutting tooth with
It is 45 degree that angle [alpha] and the number of degrees are formed between the edge of a knife, and it is 40 degree that angle β and β are provided between described often circle cutting tooth, described every
The number of teeth for enclosing cutting tooth is 10 and the number of turns of cutting tooth is 5 circles.
The technique effect of this alloy gear hob is：This hobboing cutter is applied widely, suitable for modular system or pitch system（m≤3
Or DP≤4.233）Involute profile hobboing cutter, also, be suitable for smart gear hobbing it is dry cut processing gear and be easy to processing and inspection
Survey, be efficient, wear-resisting, environmentally friendly, service life length.For this hobboing cutter under conditions of the permission of effective length of cut, it can axially alter knife
Use, easy to use and flexible.This hobboing cutter is in use, and times workpiece can reach 6-7 class precisions, and substituting roll flute reduces cost.
The processing of this hobboing cutter is simple, identical with common hobboing cutter sharpening, is not required to add special equipment.
In a kind of above-mentioned alloy gear hob, keyway is provided with described cutter shaft.
In a kind of above-mentioned alloy gear hob, described cutting tooth uses negative rake and angle is 6 degree.The structure
Design can not only improve machining condition, and to improve the durability of hobboing cutter and the flank of tooth finish of processed gear have it is very big
Benefit.
Compared with prior art, this alloy gear hob have be easy to processing and service life it is longer the advantages of.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, this alloy gear hob, including cutter hub 1 and the cutter shaft 2 with the interference fit of cutter hub 1, knife
The center of axle 2 offers axis hole 3, be circumferentially uniformly distributed with cutter hub 1 it is some circle cutting tooths 4, per adjacent two cutting tooth 4 it
Between form chip pocket 5, it is 45 degree that angle [alpha] and the number of degrees are formed between the knife back and the edge of a knife of cutting tooth 4, is often set between circle cutting tooth 4
It is 40 degree to be equipped with angle β and β, and the number of teeth for often enclosing cutting tooth 4 is 10 and the number of turns of cutting tooth 4 is 5 circles.
Further describe in detail, keyway 6 is provided with cutter shaft 2, the hobboing cutter is installed on gear hobbing lathe by keyway 6, cutting tooth 4
Use negative rake and angle is 6 degree, the preceding angle number it is reasonable in design, the design accuracy of tooth form can be improved, especially to big mould
For number hobboing cutter, lead angle is larger, and effect is more notable.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although more having used the terms such as cutter hub 1, cutter shaft 2, axis hole 3, cutting tooth 4, chip pocket 5, keyway 6 herein,
It is not precluded from the possibility using other terms.It is new just for the sake of more easily describing and explaining this practicality using these terms
The essence of type；Any additional limitation is construed as all to disagree with the utility model spirit.
