Abstract
The invention discloses a kind of straight bevel gear and manufacturing process, including bevel gear body and axis, the bevel gear body and axis are wholely set, and the bevel gear body has from root cone the first external gear teeth outstanding, and the axis has multiple second external gear teeths outstanding far from the end surface of bevel gear body.Teeth portion of the present invention is flexible, and the bending stress convenient for generating when teeth portion engagement sufficiently discharges, so that teeth portion mesh impact is small, to achieve the purpose that weaken teeth portion mesh vibration and noise；The structural strength of bevel gear body of the present invention is high, can effectively weaken stress concentration phenomenon, and the bearing capacity and anti-pressure ability of external gear teeth are good, external gear teeth not easy tooth-breaking, long service life.
Description
Technical field
The invention discloses a kind of manufacturing process of straight bevel gear, are related to field of mechanical technique.
Background technique
Bevel gear is also bevel gear, is widely used in industrial drive apparatus, differential for vehicles, locomotive, steel mill and rail
The fields such as road.Existing bevel gear load is larger, higher to processing request.
Now, gear manufacture quotient only passes through scrap build, process modification and the means such as manufacturing quality of keeping under strict control, and is likely to give birth to
Output meets the matched straight bevel gear of Designing Passenger Car Differentials.Although gear manufacture quotient takes above-mentioned measure effective, feasible, Neng Gouda
To expected purpose, but high-precision straight bevel gear manufacture difficulty obviously increases, and thus increases manufacturing cost.
Summary of the invention
The present invention provides offer and provides a kind of 4136 type straight bevel gears, this hair for the defects of above-mentioned background technique
It is bright to reduce overall weight, integrated carrying ability is improved, not easy tooth-breaking is engaged.
To achieve the above object, The technical solution adopted by the invention is as follows: a kind of straight bevel gear, including bevel gear body and
Axis, the bevel gear body and axis are wholely set, and the bevel gear body has from root cone the first external gear teeth outstanding, institute
Stating axis has multiple second external gear teeths outstanding far from the end surface of bevel gear body.
Further, the diameter of the bevel gear body is 180.5mm, and the diameter of the axis is 150.5mm.
Further, first external gear teeth is consistent with the gear direction of the second external gear teeth.
A kind of manufacturing process of straight bevel gear,
1) according to the structure of straight bevel gear, bar is forged；
2) it is machined；
3) cutting；
4) it is heat-treated；
5) gear, polishing are refined.
Further, the heat treatment successively carries out high tempering to straight bevel gear workpiece, quenching, it is ice-cold processing and
Lonneal.
Further, the high tempering is 2~3h of heat preservation at 650~670 DEG C.
Further, the quenching uses 780 ~ 800 DEG C of oil quenchings.
Further, the ice-cold processing is 1 ~ 1.5h of heat preservation under (- 70 DEG C) ~ (- 40 DEG C).
Further, the lonneal is 2~3h of heat preservation at 150~170 DEG C.
The utility model has the advantages that 1. the configuration of the present invention is simple, are easy to make.
2. teeth portion of the present invention is flexible, the bending stress convenient for generating when teeth portion engagement sufficiently discharges, so that teeth portion engagement punching
Hit it is small, to achieve the purpose that weaken teeth portion mesh vibration and noise.
3. the structural strength of bevel gear body of the present invention is high, it can effectively weaken stress concentration phenomenon, the bearing capacity of external gear teeth
It is good with anti-pressure ability, external gear teeth not easy tooth-breaking, long service life.
Detailed description of the invention
Fig. 1 the structural representation of present invention.
Specific embodiment
The implementation of technical solution is described in further detail with reference to the accompanying drawing.Following embodiment is only used for more clear
Illustrate to Chu technical solution of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figure 1, a kind of straight bevel gear is present embodiments provided, including bevel gear body 1 and axis 2, the cone tooth
Wheel body 1 and axis 2 are wholely set, and the bevel gear body 1 has from root cone the first external gear teeth 3 outstanding, and the axis 2 is separate
The end surface of bevel gear body 1 has multiple second external gear teeths 4 outstanding.
The diameter of the bevel gear body 1 is 180.5mm, and the diameter of the axis 2 is 150.5mm.
First external gear teeth 3 is consistent with the gear direction of the second external gear teeth 4.
A kind of manufacturing process of straight bevel gear,
1) according to the structure of straight bevel gear, bar is forged；
2) it is machined；
3) cutting；
4) it is heat-treated；
5) gear, polishing are refined.
Further, the heat treatment successively carries out high tempering to straight bevel gear workpiece, quenching, it is ice-cold processing and
Lonneal.
The high tempering is 2~3h of heat preservation at 650~670 DEG C.
The quenching uses 780 ~ 800 DEG C of oil quenchings.
The ice-cold processing is 1 ~ 1.5h of heat preservation under (- 70 DEG C) ~ (- 40 DEG C).
The lonneal is 2~3h of heat preservation at 150~170 DEG C.
The configuration of the present invention is simple is easy to make.
Teeth portion of the present invention is flexible, and the bending stress convenient for generating when teeth portion engagement sufficiently discharges, so that teeth portion mesh impact
It is small, to achieve the purpose that weaken teeth portion mesh vibration and noise.
The structural strength of bevel gear body of the present invention is high, can effectively weaken stress concentration phenomenon, the bearing capacity of external gear teeth and
Anti-pressure ability is good, external gear teeth not easy tooth-breaking, long service life.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
