Abstract
The invention discloses a method for machining 40Cr high-precision gears. The method is characterized by comprising steps of 1), forging blanks; 2), normalizing the blanks; 3), roughly turning various portions and reserving the allowance of 1.5-2 mm; 4), carrying out finish turning on the various portions, forming inner holes with the total lengths of phi 84.8H7 and reserving the machining allowance of 0.2 mm; 5), inspecting the blanks; 6), carrying out hobbing and reserving the tooth thickness grinding machining allowance of 0.10-0.15 mm; 7), chamfering the blanks; 8), removing burr by the aid of bench workers, 9), carrying out high-frequency quenching on toothed portions; 10), forming key slots; 11), grinding the inner holes until the total lengths of the inner holes reach phi 85H5; 12), grinding teeth; 13), generally inspecting the 40Cr high-precision gears and storing the 40Cr high-precision gears. The method for machining the 40Cr high-precision gears has the advantages that the machining efficiency can be greatly improved, the yield can be greatly increased, the production cost can be reduced, technical effects which are unforeseeable by technicians in the field can be realized, the shortcoming of long-term design set can be overcome, a novel design and machining idea can be provided, and machining effects superior to machining effects in the prior art can be realized.
Description
Technical field
The invention belongs to gear manufacture, the processing method particularly relating to a kind of 40Cr high class gear.
Background technology
Transmission being required, higher field needs to use high class gear, and high class gear is high to manufacture requirements, uses the most traditional manufacture method percent defective high, adds production cost, be unfavorable for the market competition.
Therefore the processing method that those skilled in the art are devoted to develop a kind of high class gear.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide the processing method of a kind of 40Cr high class gear, and the method saves material, easy to process, yield rate is high.
For achieving the above object, the processing method that the invention provides a kind of 40Cr high class gear, comprise the steps: 1) blank forging；2) normalizing；3) rough turn each several part, made allowance 1.5～2mm；4) finish turning each several part, endoporus, to φ 84.8H7 overall length, stays allowance 0.2 mm；5) inspection；6) gear hobbing, transverse tooth thickness stays mill allowance 0.10～0.15 mm；7) chamfering；8) pincers worker deburring；9) teeth portion high-frequency quenching；10) keyseat；11) mill endoporus is to φ 85H5；12) roll flute；13) always check in storehouse.
The invention has the beneficial effects as follows: the processing method of the high class gear of the present invention improves greatly working (machining) efficiency, yield rate, reduce production cost, achieve the unforeseeable technique effect of those skilled in the art, overcome design set for a long time, provide a kind of new design and processing thought, and achieve more more preferable processing effect than prior art.
Detailed description of the invention
The processing method that the technical scheme is that a kind of 40Cr high class gear, comprises the steps: 1) blank forging；2) normalizing；3) rough turn each several part, made allowance 1.5～2mm；4) finish turning each several part, endoporus, to φ 84.8H7 overall length, stays allowance 0.2 mm；5) inspection；6) gear hobbing, transverse tooth thickness stays mill allowance 0.10～0.15 mm；7) chamfering；8) pincers worker deburring；9) teeth portion high-frequency quenching；10) keyseat；11) mill endoporus is to φ 85H5；12) roll flute；13) always check in storehouse.
The processing method of the high class gear of the present invention improves greatly working (machining) efficiency, yield rate, reduce production cost, achieve the unforeseeable technique effect of those skilled in the art, overcome design set for a long time, provide a kind of new design and processing thought, and achieve more more preferable processing effect than prior art.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to the design of the present invention without creative work.Therefore, all technical staff in the art, all should be in the protection domain being defined in the patent claims the most on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
