A second external gear teeth, the root portion of first external gear teeth are linked to be the interconnecting piece of a circle on wheel body, outside adjacent described first
Root portion between the opposite flank of tooth of the gear teeth includes two identical interconnecting pieces, and the interconnecting piece is that side is semicircular arc-shaped, and two
One end of a interconnecting piece connects, and the root portion of the first external gear teeth of two other ends connected and two sides connects.
Further, the diameter of the bevel gear body is 160.5mm, and the diameter of the axis is 150.5mm.
Further, the outer end face of the external gear teeth is in plane, and the side of external gear teeth is raised to two sides, the side of external gear teeth
Face is connect with interconnecting piece.
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, rapid cooling and low temperature
Tempering.
Further, the high tempering is 2~3h of heat preservation at 650~670 DEG C.
Further, the quenching refers to that temperature is directly passed through cooling medium in 650~670 DEG C of bevel gear is cold
But, the cooling medium is water, salt water, kerosene or air.
Further, the rapid cooling is for straight bevel gear to be placed in air then while air-cooled to bevel gear
The combined cooling of spray, the rapid cooling mode duration is on 0 .5 hours.
Further, the lonneal is 1~2h 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, the heat treatment process of bevel gear is greatly simplified, simultaneously
Processing cost can also be reduced.
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.
