Description
Technical field
The present invention relates to bevel gear making technical fields, and in particular to a kind of bevel gear machining method.
Background technique
Sector is the radially outer semicircular arc-shaped rack structure of the flank of tooth, and along the processing of same axis, there are two radial at both ends
Hole is mainly used in servo-control system, controls the direction of motion of object, makes to be controlled object always to just another object,
For the afterbody of multi-stage speed-reducing, there is axially and radially two completely self-contained freedom degrees, to reach two movement between not mutually
Interfere (component motion zero), then needs to guarantee two radial holes and sector is axially vertical and two radial holes are coaxial, axial bore and outside
The outer circle of circle concentricity, the female coaxial at both ends and both ends is coaxial；The method that the prior art processes sector is usual are as follows: blanking-is thick
Vehicle-smart car-processing tooth form-is heat-treated-is machined to finished product, due to that can generate machining stress in Tutrning Process, at product heat
Deflection is larger after managing and being cut into semicircle, leads to poor product quality, and qualification rate is low.
Therefore, it is necessary to a kind of sector processing methods, and the deflection after reducing product heat treatment guarantees product quality, improves
Qualification rate.
Summary of the invention
Goal of the invention: in view of the deficiency of the prior art, the present invention provides a kind of bevel gear machining method, can subtract
Deflection after miscellaneous goods heat treatment, guarantees product quality, improves qualification rate.
Technical solution: to achieve the above object, the present invention adopts the following technical scheme:
A kind of bevel gear machining method, includes the following steps:
Step 1: base；
Step 2: wheel blank and the Roughing and fine machining for installing connecting portion；Using the method that numerically-controlled machine tool process is concentrated to wheel blank
It is processed；
Step 3: to wheel blank cutting on gear cutting machine；
Step 4: wheel blank being heat-treated using carburizing and quenching technique；
Step 5: gear lapping；
Step 6: phosphatization；
Step 7: skin processing；
Step 8: pairing.
Preferably, the base includes the following steps:
Step 2.1: die forging cone of support gear blank；
Step 2.2: bevel gear blank is subjected to normalized treatment；
Step 2.3: the oxide skin of removal bevel gear blank surface.
Preferably, in step 2.3, using the oxide skin of ball blast or pickling removal bevel gear blank surface.
Preferably, in step 3, the gear cutting machine include slightly cut bull wheel, fine cut bull wheel, slightly cut steamboat, fine cut steamboat concave surface,
5, fine cut steamboat convex surface etc. gear cutting machine.
It preferably, step 4, well include Anti-seeping technology process after the heat treatment.
The utility model has the advantages that lower production costs and save material, simple process and it is easily manipulated, applied widely, Neng Gouman
The demand for development of sufficient current enterprise；Deflection after product heat treatment can be reduced, guarantees product quality, improves qualification rate.
Specific embodiment
Further explanation is done to the present invention below with reference to embodiment.
A kind of bevel gear machining method, includes the following steps:
Step 1: base；
Step 2: wheel blank and the Roughing and fine machining for installing connecting portion；Using the method that numerically-controlled machine tool process is concentrated to wheel blank
It is processed；
Step 3: to wheel blank cutting on gear cutting machine；The bevel gear produced in pairs first processes gear wheel, reprocesses pinion gear.
Step 4: wheel blank being heat-treated using carburizing and quenching technique, has reached that tooth surface is hard and center portion is tough
Performance requirement.Surface hardness is 58-64HRC.Tooth root centre hardness is 30-45HRC.
Step 5: gear lapping；Gear lapping can improve meshing quality, reduce tooth-face roughness and meshing noise.
Step 6: phosphatization；Tissue looseness's store oil of phosphate coating is conducive to gear pair in running-in period and places early stage sharp wear,
Gear beauty, anti-corrosion after phosphatization.
Step 7: skin processing；Skin processing is to keep transmission more flat to improve the precision of the flank of tooth, surface roughness etc.
Surely.
Step 8: pairing.Pairing process is the final inspection of meshing quality in bevel gear manufacturing process.With checking machine, pacifying
The routine inspection that contact zone, sideshake and sideshake variation and meshing noise are carried out under the conditions of dress, is allowed to dispatch from the factory in pairs.
Preferably, the base includes the following steps:
Step 2.1: die forging cone of support gear blank；
Step 2.2: bevel gear blank is subjected to normalized treatment；
Step 2.3: the oxide skin of removal bevel gear blank surface.
Preferably, in step 2.3, using the oxide skin of ball blast or pickling removal bevel gear blank surface.
Preferably, in step 3, the gear cutting machine include slightly cut bull wheel, fine cut bull wheel, slightly cut steamboat, fine cut steamboat concave surface,
5, fine cut steamboat convex surface etc. gear cutting machine.
It preferably, step 4, well include Anti-seeping technology process after the heat treatment.
According to following embodiments, the present invention can be better understood.However, as it will be easily appreciated by one skilled in the art that real
It applies specific material proportion, process conditions and its result described in example and is merely to illustrate the present invention, without that should will not limit
The present invention described in detail in claims processed.
