Description
Technical field
The utility model relates to one the combined internal 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 internal 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 common internal gear for form copyings 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: → tempering that blanking → material forges (eliminate material fracture and pore) (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 the common internal gear of tooth processing 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 the common internal gear of lost wax casting method precision casting tooth processing, 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: the common internal gear of metallic dust die casting machine casting tooth processing 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.
Summary of the invention
The technical problem that the utility model solves is: complex process during in order to solve prior art machining interal, long processing time, difficulty of processing are large, processing cost high-technology defect, a kind of internal gear is provided, particularly relate to that a kind of toothed thin slice 1/2 gear shape part quenched by multi-disc is formed by stacking and fill dwell set mould assembly internal gear with metal layer, reaching low cost, manufacturing the technical purpose of high physical property internal gear fast.
The technological scheme of the utility model technical solution problem is:
In order to reach technical purpose of the present utility model, the one that the utility model provides has the combined internal gear of metal sandwich, comprises combination internal tooth wheel body, it is characterized in that: combination internal tooth wheel body is formed by stacking mutually by multi-disc sheet parts;
Described sheet parts is the circle that thin slice 1/2 internal gear parts of two panels quenching is spliced into relatively;
Sheet parts repeats to stack to internal gear design thickness, and misplacing 90 ° between relative two-layer sheet parts stacks;
Described multi-disc sheet parts superposition, forms combination internal tooth wheel body, connects, soldering point at least two between multi-disc sheet parts with spot welding;
There is metal layer between each sheet parts of combination internal tooth wheel body and the surface of combination internal tooth wheel body;
Metal layer is selected from following any one: lead layer, tin layers, layers of copper, aluminium lamination.
Compare with current internal gear, the Advantageous Effects that the utility model obtains is: by first being quenched by web gear shape part, then overall immersion metallic solution after formative gear, the single individuality of part is little, be convenient to quenching technical, be convenient to produce heavy parts, compared with prior art overall gear quenching technical, reduce the volume of hardening furnace, especially the large gear that thickness is large, during prior art quenching, warm-up time is very long just can make whole gear heat to the temperature required for quenching, therefore, web gear shape part carries out the technique of quenching, shorten warm-up time, be convenient to control of product quality, reduce the difficulty of quenching technical, between sheet parts and the surface of gear mass is all flexible metallic material, after stressed extruding, flexible metal can be extruded from the flank of tooth or simply remove, be convenient to control product design precision, do not affect tooth face hardness and flank of tooth physical parameter, add and adopt vacuum processing technology man-hour, vacuum state can discharge the gas in metallic solution, rapid pressure and fast decompression process hocket, metallic solution produces motion in gear mass, in accelerating gear body, air is discharged, make in gear mass finer and close, improve gear mass mechanical property, the utility model patent simplified processing process, shorten process time, reduce difficulty of processing, reach low cost, the technical purpose of the high physical property gear of quick manufacture, complex process when solving prior art machining gears, long processing time, difficulty of processing is large, processing cost high-technology defect, and produce the more outstanding above-mentioned technological deficiency of large gear, practicability is large.
