Description

A kind of internal gear of gluing interlayer

Technical field

The utility model patent relates to a kind of internal gear of gluing interlayer, particularly relates to the internal gear having adhesive layer between sheet parts that a kind of toothed web gear shape part quenched by multi-disc is formed by stacking.

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 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 or special shape gear.

Summary of the invention

The technical problem that the utility model patent 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 the gear having adhesive layer between sheet parts that a kind of toothed web gear shape part quenched by multi-disc is formed by stacking, reach low cost, manufacture the technical purpose of high physical property internal gear fast.

The technological scheme of the utility model patent technical solution problem is:

In order to reach the technical purpose of the utility model patent, the internal gear of a kind of gluing interlayer that the utility model patent provides, comprises internal tooth wheel body, it is characterized in that: internal tooth wheel body is formed by stacking mutually by multi-disc thin slice internal gear parts;

Described thin slice internal gear parts is the thin slice circular pieces that the inside of metal is distributed with the quenching of tooth;

Described thin slice internal gear parts there is more than one attachment hole;

Multi-disc thin slice internal gear parts is superimposed to design thickness mutually;

Attachment hole after the superposition of multi-disc thin slice internal gear parts is overlapped into through hole;

Internal tooth wheel body is fixedly connected into link between attachment hole;

There is the adhesive layer of solidification between each thin slice internal gear parts of internal tooth wheel body and the surface of internal tooth wheel body;

It is that rivet interlacement or screw and nut connect that link is fixedly connected with.

An internal gear for the gluing interlayer be more preferably, 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.

With current gear ratio comparatively, the Advantageous Effects that the utility model patent obtains is: by first being quenched by web gear shape part, then overall immersion adhesive 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, 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 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.
