Description
Technical field
The invention belongs to mechanical technology technical fields, and in particular to a kind of angular gear processing technology.
Background technology
Gear is the colyliform machine components that torque is transmitted by the engagement of tooth.Gear with other dentation machine components by passing
It moves, it can be achieved that changing the functions such as rotating speed and torque, the change direction of motion and change forms of motion.Due to transmission efficiency, transmission
Than the advantages that accurate, power bracket is big, gear mechanism extensive use in industrial products, design is directly affected with manufacture level
To the quality of industrial products.Gear tooth, which mutually clasps gear, can drive the rotation of another gear to transmit power.By two teeth
Wheel separates, and can also drive the gear on both sides using chain, crawler belt, belt and transmit power.
The loaded down with trivial details complexity of entire processing technology of gear, for the higher gear of a few thing strength often also need into
Row Surface heat-treatent such as case-carbonizing etc. enhances the rigidity of teeth portion, then often gear size is caused to become larger after carburizing,
For the high gear of some required precisions, this absolutely not allows for this, therefore must arrange to finish after being heat-treated, essence
Clamping workpiece in process just causes waste product at a difficult problem because careless slightly will crush the gear teeth.In addition, right
In addition to the gear teeth to be processed for some gears, also other machining processes, such as drill, groove milling etc., these are required for
Ensure to carry out reasonable clamping to workpiece in the case of gear teeth health.
