Abstract
The invention discloses a manufacturing method for bevel gears of agricultural cultivators, which relates to the technical field of gear manufacturing. A bevel gear kinematic pair is provided with a big bevel gear and a small bevel gear which are engaged with each other. The manufacturing method includes the following steps: (A) respective forging of the gear blanks of the big bevel gear and the small bevel gear; (B) annealing of the gear blanks of the two gears; (C) respective machining of the gear blanks of the big bevel gear and the small bevel gear; (D) heat treatment; (E) tempering. Compared with the prior art, the manufacturing method solves the problem that the teeth of the conventional bevel gear kinematic pair can easily crack in the process of transmitting power.
Description
Technical field
The present invention relates to gear machining technology field, especially a kind of processing method of the conical gear kinematic pair for agricultural ploughing machine.
Background technology
Conical gear kinematic pair is one of commonplace Poewr transmission mechanism adopting on farm machinery, it
Both the direction that power transmits can be changed, the rotating speed of power output can be changed simultaneously.Have a kind of conical gear kinematic pair of agricultural ploughing machine, its large conical gear and small conical gear are all to be processed by lower bar.There are the following problems in process of production for this processing method: tooth phenomenon easily appears collapsing in conical gear kinematic pair in transferring power process.
Summary of the invention
Problem to be solved by this invention is to provide a kind of processing method of agricultural ploughing machine conical gear, to solve the moving secondary problem that easily collapses tooth in transferring power process of existing conical gear.
In order to address the above problem, the technical solution used in the present invention is: a kind of processing method of agricultural ploughing machine conical gear, and conical gear kinematic pair has a pair of intermeshing cone gear and cone pinion, and it comprises the following steps:
A, forge respectively the tooth base of described cone gear and described cone pinion;
B, the described tooth base of two kinds of gears is carried out to annealing in process;
The described tooth base of C, the respectively described tooth base to described cone gear and described cone pinion is processed:
1) the described tooth base processing of described cone gear is comprised:
The large end end face-car of the drill centers-car small end end face-car conical surface-garland key;
Use fixture to carry out Gear Milling and obtain described cone gear completing the conical surface of described tooth base of described cone gear of turning processing;
2) the described tooth base processing of described cone pinion is comprised:
The large end end face-car of car small end end-car conical surface;
Use fixture to carry out Gear Milling and obtain described cone pinion completing the conical surface of described tooth base of described cone pinion of turning processing;
