Description
Technical field
The utility model relates to one the combined cone inclined gear of metal sandwich, particularly relates to that a kind of toothed thin slice 1/2 gear shape part quenched by multi-disc is formed by stacking and fills dwell set mould assembly cone inclined gear with metal layer.
Background technique
Gear refers to, and wheel rim has tooth can engage the mechanical component transmitting motion and power continuously, the initial gear transmission of China was brought into use from the period of Three Kingdoms, started there is gear-driven record at B.C. 300 years abroad, therefore, gear transmission at mechanical field from ancient times with regard to extensive use.
Common gear can be divided into cross section to be circular gear, the non-circular special shape gear of tooth bar and cross section from outward appearance.
Conventional gear working method is generally divided into form copying and generating cutting, such as: gear hobbing machine gear hobbing process, milling machine Gear Milling, slotting machine Gear Shaping, cold forging machine forge the methods such as tooth processing, the processing of gear generator gear-shaping, the processing of accurate casting tooth, the processing of gear grinding machine roll flute, the processing of die casting machine casting tooth, gear shaving machine processing.
Such as: produce ordinary conical helical gear for the form copying such as gear hobbing machine gear hobbing process, milling machine Gear Milling, slotting machine Gear Shaping, the processing of gear generator gear-shaping, the processing of gear grinding machine roll flute, gear shaving machine processing, processing technology must have: blanking → material forges (eliminating material fracture and pore) → tempering (reduce and cut difficulty) → outer garden profile and interior garden profile cut → line → calibration profiling Gear shape process → keyway processing → quenching → flank of tooth honing fine finishing → inspection → warehouse-in is carried out to each tooth.
Such as: forge tooth processing ordinary conical helical gear for cold forging machine, processing technology must have: (technique is loaded down with trivial details, slightly to forge Mould Machining.) → heating materials → forge processing → gear surface roughing → heat treatment → gear surface fine finishing → inspection → warehouse-in; Each mould can only produce the gear of a model.
Such as: for lost wax casting method precision casting tooth processing ordinary conical helical gear, processing technology must have: (technique is loaded down with trivial details, slightly for the processing of metal wax-pattern.) → wax-pattern is shaped, and (technique is loaded down with trivial details, slightly.) → sand mo(u)ld shaping → sand mo(u)ld dewaxing → metal melt → cast → the demoulding → sand removal → gear surface fine finishing → inspection → warehouse-in; Cast gear is generally not suitable for heat treatment process, and therefore, the strength of gear of production is little, generally can not heat treatment further, and each mould can only produce the gear of a model.
Such as: metallic dust die casting machine casting tooth processing ordinary conical helical gear is example, and processing technology must have: (technique is loaded down with trivial details, slightly for Mould Machining.) → metallic dust die casting machine casting tooth → gear surface fine finishing → inspection → warehouse-in; Cast gear is generally not suitable for heat treatment process, and therefore, the strength of gear of production is little, generally can not heat treatment further, and each mould can only produce the gear of a model.
In order to ensure physical accuracy and the mechanical strength of gear, no matter adopt above arbitrary processing method, all have that actual processing technology complexity, long processing time, difficulty of processing are large, processing cost high-technology defect, these technological deficiencies are more outstanding when production large gear.
