Description
Technical field
The utility model relates to the tooth bar that a kind of many sheet parts have metal-to-metal adhesive adhesion coating therebetween, particularly relates to that a kind of toothed sheet parts quenched by multi-disc is formed by stacking and fills the tooth bar in gap with metal-to-metal adhesive adhesion coating.
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 straight toothed spur 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 straight toothed spur 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 straight toothed spur 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 straight toothed spur 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 tooth bar, 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 the large-scale tooth bar of production.
Summary of the invention
The technical problem that the utility model solves is: complex process during in order to solve prior art manufacturing gear strip, long processing time, difficulty of processing are large, processing cost high-technology defect, a kind of tooth bar is provided, particularly relate to that a kind of toothed sheet parts quenched by multi-disc is formed by stacking and with the tooth bar in metal-to-metal adhesive adhesion coating filling gap, reach the technical purpose of low cost, the fast high physical property tooth bar of manufacture.
The technological scheme of the utility model technical solution problem is:
In order to reach technical purpose of the present utility model, a kind of many sheet parts that the utility model provides have the tooth bar of metal-to-metal adhesive adhesion coating therebetween, comprise toothed thin slice rack-shaped part, tooth bar body, it is characterized in that:
Described thin slice rack-shaped part is the toothed sheet metal of the rack-shaped of the sheet of quenching;
Described tooth bar body is formed by stacking mutually by multi-disc toothed thin slice rack-shaped part;
Described multi-disc thin slice rack-shaped part superposition, connects with spot welding between multi-disc thin slice rack-shaped part, soldering point at least two;
There is the adhesive layer containing metal powder of solidification between described each sheet parts and the surface of tooth bar body, is the gluing interlayer of metal;
Metal powder is selected from following any one: lead powder, glass putty, copper powder, aluminium powder.
The many sheet parts be more preferably have a tooth bar for metal-to-metal adhesive adhesion coating therebetween, it is characterized in that: adhesive layer is the adhesive layer that solidifies of the adhesive layer of epoxy resin adhesive solidification containing metal powder or the quick-drying structure glue containing metal powder or the adhesive layer of the Structural Hardware adhesive curing containing metal powder.
The many sheet parts be more preferably have a tooth bar for adhesive layer therebetween, it is characterized in that: adhesive layer is the adhesive layer of epoxy resin adhesive solidification, or the adhesive layer of quick-drying structure glue solidification, or the adhesive layer of Structural Hardware adhesive curing.
Compare with current tooth bar, the Advantageous Effects that the utility model patent obtains is: by first being quenched by thin slice rack-shaped part, then overall immersion adhesive after forming tooth bar, the single individuality of part is little, be convenient to quenching technical, be convenient to produce heavy parts, compared with the overall rack quenching technique of prior art, reduce the volume of hardening furnace, especially the large-scale tooth bar that thickness is large, during prior art quenching, warm-up time is very long just can make whole tooth bar heat to the temperature required for quenching, therefore, thin slice rack-shaped part carries out the technique of quenching, shorten warm-up time, be convenient to control of product quality, reduce the difficulty of quenching technical, add and adopt vacuum processing technology man-hour, vacuum state can discharge the gas in adhesive, rapid pressure and fast decompression process hocket, adhesive produces motion in tooth bar body, accelerate air in tooth bar body to discharge, make in tooth bar body finer and close, improve tooth bar body mechanical property, add metal powder in adhesive, metal powder solidifies the adhesive layer forming metal-containing powder together with adhesive, makes in tooth bar body finer and close, improves tooth bar body mechanical property, the utility model patent simplified processing process, shorten process time, reduce difficulty of processing, reach low cost, manufacture the technical purpose of high physical property tooth bar fast, complex process when solving prior art manufacturing gear strip, long processing time, difficulty of processing are large, processing cost high-technology defect, and produce the more outstanding above-mentioned technological deficiency of large-scale tooth bar, practicability is large.
