Description
Technical field
The utility model relates to a kind of tooth mode structure for spiral bevel gear forging near-net-shape.
Background technology
Spiral bevel gear comprises bull wheel and steamboat two parts.The tooth mould of common spiral bevel gear forging and molding adopts three/tetra-axle spark machined or machining center directly to process, and the processing of copper service message pole is nothing more than following two kinds of processing methods: 1. processed copper service message pole by three/Four-axis milling center; 2. by spiral bevel gear tooth milling machine, copper service message pole is processed.When the built-up welding of tooth model chamber being filled after the wearing and tearing of tooth mould, after annealing, use the public electrode machining of copper again.The processing technology production cost of this tooth mode structure and tooth mould is high, the production cycle is long, and the precision of tooth mould is not easy inspection and controls, and high tooth mould surface roughness needs the spark erosion equipment of import and good discharge medium to ensure.
Summary of the invention
The utility model provides a kind of tooth mode structure for spiral bevel gear forging near-net-shape, solves the problems referred to above.
The technical scheme that the utility model is taked: a kind of tooth mode structure for spiral bevel gear forging near-net-shape, it is characterized in that: described tooth mode structure is combination die, comprise profile of tooth assembly, described profile of tooth assembly is made up of the large end of assembly, assembly small end and fan-shaped bracing frame, the large end of assembly and assembly small end respectively have a fan-shaped bracing frame, the covering of the fan angle of fan-shaped bracing frame is the 360/ gear number of teeth, and the profile of tooth assembling components of number identical with the gear number of teeth forms tooth mode structure
Described fan-shaped bracing frame faying face is smooth, and the cylindrical of fan-shaped bracing frame is taper seat, and coning angle and the tooth-formation of gear of taper seat adapt.
The beneficial effects of the utility model:
1, tooth mode structure of the present utility model is combination die, and each profile of tooth is an independent assembly, install and easy to process;
2, the tooth components of wearing and tearing can be changed separately, shorten time to wait;
3, profile of tooth assembly is processed by forging and forming technology, improves the anti-fatigue performance of profile of tooth;
4, profile of tooth assembly can carry out thick fine finishining on three axis machining center, and precision and surface roughness all can control.
Accompanying drawing explanation
Fig. 1 is single profile of tooth modular construction schematic diagram;
Fig. 2 is the tooth mode structure schematic diagram after combination.
In figure: 1. the large end of assembly, 2. assembly small end, 3. fan-shaped bracing frame, 4. profile of tooth assembly.
Detailed description of the invention
Be described in detail of the present utility model below in conjunction with drawings and Examples.
The utility model provides a kind of tooth mode structure for spiral bevel gear forging near-net-shape, described tooth mode structure is combination die, comprise profile of tooth assembly, described profile of tooth assembly is made up of the large end of assembly, assembly small end and fan-shaped bracing frame, the large end of assembly and assembly small end respectively have a fan-shaped bracing frame, the covering of the fan angle of fan-shaped bracing frame is the 360/ gear number of teeth, and the profile of tooth assembling components of number identical with the gear number of teeth forms tooth mode structure
Described fan-shaped bracing frame faying face is smooth, and the cylindrical of fan-shaped bracing frame is taper seat, and coning angle and the tooth-formation of gear of taper seat adapt.
The utility model be in order to forge that near-net-shape spiral bevel gear puts forward a kind of can the tooth mode structure of quick and convenient processing.The face cone of forging steamboat controls material by the inner conical surface of circle stress to flow and is formed, and the forging and molding of bull wheel determines by the shape of assembly after combining.
The large small end of profile of tooth respectively has a fan-shaped bracing frame, and the covering of the fan angle of each fan-shaped bracing frame is the 360 °/gear number of teeth, by assembling N number of identical assembly, just can form tooth mode structure.
Fan-shaped bracing frame faying face is smooth, can ensure coplanar flat on the tooth mould after combining.The cylindrical of fan-shaped bracing frame is taper seat, and can fit tightly with the internal conical surface of circle stress, the coning angle of taper seat is determined according to tooth-formation of gear, is generally not more than 40 °.
Each profile of tooth assembly is identical, can by the mode of forging and molding by assembly dumming, the fine finishining before then carrying out heat according to digital modeling in the heart in three axis machining and after heat.There is profile of tooth wear out failure in forging process, this profile of tooth unit replacement can be fallen.For convenience of dismounting, fixed assembly will determine its built-up sequence.
