Abstract
The invention provides a drive bevel gear machining method. The method includes the steps of blank making, rough and fine machining of a wheel blank and the installation connecting portions, gear cutting, heat treatment, fine machining of the installation connecting portions, gear grinding, phosphorization and pairing. The blank is formed through a die forging method, the forged blank is subjected to normalizing treatment, the forging stress is eliminated, the hardness value after normalizing is carried out is 156-207 HBS, and the forged blank is cleaned in a shot blasting or shot blasting mode after being subjected to the normalizing treatment. The wheel blank is machined by a multi-axis lathe through centralized processes or machined by a lathe and a centralized through disperse processes. Gear cutting is carried out in a face milling mode or face rolling mode. The heat treatment adopts a carburizing and quenching heat treatment technology. The process of the drive bevel gear machining method is optimized, the process takt time is shortened greatly, the technological process is shortened, the stock of goods in process is reduced, and beneficial experience is provided for turning of similar axis parts.
Description
Technical field
The present invention relates to a kind of drive bevel gear processing method, belong to field of mechanical technique.
Background technology
Traditional turning process adopts the technique based on copying lathe, and not only operation is many, long flow path, and quality control and logistics management all can not meet the requirement of Lean Manufacturing.There is following shortcoming in original production line: what machine tool equipment fell behind the employing of original processing technology is copying lathe, the clamping position that processing dimension relies on operator manually to adjust cutter completely controls, not easily, quality fluctuation is comparatively large, can only adopt the technique that thick finish turning separates for cutter changing; Piece-holder mode causes the normally first holding workpiece one end of the how original turning process of operation, the processing other end, then exchanges the mode of processing, altogether needs two procedures just can complete processing; The blank of the large workpiece of blank removal amount is forging part, and average allowance is 2.5MM, must be divided into repeatedly feed, not only time-consuming, and waste of material is also very large.
Summary of the invention
The invention provides a kind of drive bevel gear processing method, operation reduces, and flow process end, production time per piece shortens greatly.
For solving above technical problem, the invention provides following technical scheme: a kind of drive bevel gear processing method, process route comprises: the fine finishining-gear lapping-phosphatization-pairing of the Roughing and fine machining-cutting-heat treatment-installation connecting portion of base-wheel blank and installation connecting portion; Blank is made up of the method for die forging, and forging stock is through normalized treatment, and eliminate forging stress, the hardness number after normalizing is 156-207HBS, clears up after forging stock normalized treatment, and the method for cleaning adopts ball blast or pickling processes; The method that wheel blank processing adopts multiple spindle lathe operation to concentrate or the method adopting lathe and copying lathe operation to disperse; The cutting process that cutting adopts is that method is rolled in facing cut method or face; Wherein heat treatment adopts carburizing and quenching technique, and case hardness is 58-64HRC, and tooth root centre hardness is 30-45HRC; Anti-seeping technology is carried out at installation screw, the jump-ring slot position of bevel gear; In fine grinding bevel gear the heat treatment of dish type bull wheel after carry out grinding location endoporus.
Further, wherein normalized treatment adopts isothermal normalizing process.
This sleeve flange processing method that the present invention relates to, process optimization, shortens technological process, improves product serviceability.
