This hobbing cutter of processing hypodontia gear, including the cutter body that has the axial hole, the surface equipartition of cutter body has along the axially extended tooth row of cutter body, the cutting teeth that has a plurality of even settings on the tooth is arranged, the tooth's socket has between double -phase neighbour's the cutting teeth, if the quantity of cutting teeth is X, it is Y to wait to process the gear teeth number, edentulous quantity is Z in waiting to process the gear, X= (Y so Z, ) Z, one of them cutting teeth is and the tooth, and the thickness of tooth is the thickness of the thickness of two cutting teeths with a tooth's socket. The utility model discloses can effectively improve the machining efficiency of hypodontia gear, have advantages such as low in manufacturing cost, product quality height.
Description
Technical field
This utility model belongs to process tool technical field, relates to a kind of hobboing cutter, a kind of hobboing cutter processing teeth-missing gear.
Background technology
Teeth-missing gear as shown in Figure 1 is widely used in automobile gearbox, tradition teeth-missing gear processing method typically through gear hobbing, draw two steps of tooth, i.e. carry out again four times the gear after gear hobbing drawing tooth just can machine, the wayward size of this processing method and symmetry, the product processed has an obvious step at all, and long processing time, operation is many, efficiency is low, and processing cost is high.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that the hobboing cutter of a kind of processing teeth-missing gear that can be effectively improved teeth-missing gear working (machining) efficiency.
The purpose of this utility model can be realized by following technical proposal:
The hobboing cutter of this processing teeth-missing gear, including the cutter hub with axial bore, the outer surface of described cutter hub is evenly equipped with along the axially extended tooth row of cutter hub, there is on described tooth row some cutting teeth being uniformly arranged, between two adjacent cutting teeth, there is teeth groove, it is characterized in that, if the quantity of cutting tooth is X, the number of teeth of gear to be processed is Y, in gear to be processed, the quantity of hypodontia is Z, so X=(Y-Z)/Z, one of them cutting tooth is and tooth, and described and tooth thickness is the thickness that two thickness cutting teeth add a teeth groove.
Hypodontia in gear the most to be processed occurs the most in pairs, and is tooth.
In the hobboing cutter of above-mentioned processing teeth-missing gear, described Y=36, Z=4, X=8.This utility model is mainly used in the teeth-missing gear in manuscript 1, it is known that the number of actual teeth of teeth-missing gear is 36-4=32, has 4 hypodontia positions, and is uniformly distributed, then cutting tooth can be set to 8, can be effectively improved working (machining) efficiency once by teeth-missing gear molding.
In the hobboing cutter of above-mentioned processing teeth-missing gear, the 8th cutting tooth is and tooth.
In the hobboing cutter of above-mentioned processing teeth-missing gear, described cuts the inclined-plane of both sides before and after tooth includes crest top land and is positioned at crest top land, and described inclined-plane is pressure angle with the angle in cutter hub cross section, and described pressure angle is 20 °.
In the hobboing cutter of above-mentioned processing teeth-missing gear, described tooth row is 12 and is evenly distributed on described cutter hub, if dry cutting tooth Spiral distribution is on described cutter hub, its helical angle is 15 °, and lead angle is 9 °.
Compared with prior art, the hobboing cutter of this processing teeth-missing gear has the advantage that
Can directly process finished product teeth-missing gear by this hobboing cutter, eliminate four times and draw tooth technique, substantially increase production efficiency, and reduce cost, the teeth-missing gear profile processed is complete, and precision is high.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is further described, but this utility model is not limited to these embodiments.
The hobboing cutter of processing teeth-missing gear as shown in Figure 2, including the cutter hub 1 with axial bore 11, the outer surface of cutter hub 1 is evenly equipped with along the axially extended tooth row of cutter hub 1 12, there is on tooth row 12 some cutting teeth 2 being uniformly arranged, between two adjacent cutting teeth 2, there is teeth groove 3, if the quantity of cutting tooth 2 is X, the number of teeth of gear to be processed is Y, in gear to be processed, the quantity of hypodontia is Z, so X=(Y-Z)/Z, one of them cutting tooth 2 is and tooth 4, and the thickness that the thickness of tooth 4 is two cutting teeth 2 adds the thickness of a teeth groove 3.Hypodontia in gear the most to be processed occurs the most in pairs, and is tooth.
Teeth-missing gear as shown in Figure 1, it is known that the number of actual teeth of teeth-missing gear is 36-4=32, has 4 hypodontia positions, and is uniformly distributed, then Y=36, Z=4, X=8, can be set to 8 by cutting tooth 2, can be effectively improved working (machining) efficiency once by teeth-missing gear molding.
As in figure 2 it is shown, the 8th cutting tooth 2 is and tooth 4 from left to right.
As in figure 2 it is shown, cutting tooth 2 includes crest top land 21 and is positioned at the inclined-plane 22 of crest top land 21 both sides front and back, inclined-plane 22 is pressure angle with the angle in cutter hub 1 cross section, and pressure angle is 20 °.
As it is shown on figure 3, tooth row 12 is 12 and is evenly distributed on cutter hub 1, if dry cutting tooth 2 Spiral distribution is on described cutter hub 1, its helical angle is 15 °, and lead angle is 9 °.
Can directly process finished product teeth-missing gear by the hobboing cutter of this processing teeth-missing gear, eliminate four times and draw tooth technique, substantially increase production efficiency, and reduce cost, the teeth-missing gear profile processed is complete, and precision is high.
Specific embodiment described herein is only to this utility model spirit explanation for example.Described specific embodiment can be made various amendment or supplements or use similar mode to substitute by this utility model person of ordinary skill in the field, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
