Abstract
The utility model discloses a clamping fixture for reducing quenching deformation of a gear ring. The clamping fixture is a flange-shaped member; the main body of the clamping fixture is plugged into a heated gear ring in a normal temperature state; and the flange edge is in clearance fit with a port ring of the gear ring. In the clamping fixture, the outer wall of the main body of the clamping fixture is in fit with small-diameter inner teeth of the gear ring, and the fit clearance is required to be determined within a range of between 0.08mm and 0.10mm according to the diameter and the accuracy of the gear ring. The clamping fixture is plugged into the gear ring which has been heated to quenching temperature to be quenched together, so that the quenching deformation of the gear ring is restrained by the rigid clamping fixture and is guaranteed to be controllable. The clamping fixture has a simple structure, is easy to disassemble and assemble and is particularly suitable for match production and matching.
Description
Technical field
The utility model relates to a kind of mold that reduces the heat treatment of workpieces distortion, and specifically, the utility model relates to a kind of mold that is out of shape when gear ring quenches that reduces.
Background technology
Gear ring commonly used is made transmission component in the big machinery, adopts the method for quenching to improve physical strength and wear resisting property usually for the gear ring that bears heavy lift.Gear ring is a kind of annular member, and structural strength and rigidity are relatively low, and quenching under unconfined situation easily deforms.Quenching strain must reduce the former machining precision of gear ring, makes follow-up supporting downgrade.Gear ring after the quenching is higher because of hardness, is difficult to revise with conventional method.Prior art adopts to turn presses the technology of quenching can realize reducing the gear ring quenching deformation purpose, the equipment price costliness of this complete sets of Techniques, and it is supporting only to be fit to produce streamline in enormous quantities, and small serial production is incorrect because of the input and output ratio, so be not suitable for supporting.
The utility model content
The utility model is primarily aimed at the prior art support equipment and costs an arm and a leg, and applies difficult problem, proposes a kind of mold that reduces gear ring quenching deformation, and this positioner structure is simple, easy to manufacture, can limit the gear ring heat treatment deformation.
The utility model is achieved through the following technical solutions technical object.
Reduce the mold of gear ring quenching deformation, it is the flange-like member, and its main body is filled under the normal temperature state and installed in the gear ring endoporus that has heated, flange and gear ring choma running fit.Its improvements are: described mold main body outer wall cooperates with the path of gear ring internal tooth, and tolerance clearance is 0.08mm～0.10mm.
In the said structure, mold cooperates with the gear ring that has heated by face of matching and flange, forms an one-piece construction.
The utility model compared with prior art has following positively effect.
1, simple, the low cost of manufacture of the positioner structure of flange-like;
2, the mold of end play shrink-fit structure, heat are installed easily, cooling back convenient disassembly;
3, the corresponding tooth of mold and gear ring meshes the formation one-piece construction jointly, has increased structural strength, significantly reduces the gear ring deflection when quenching with stove, improves the quenching quality.
Description of drawings
Accompanying drawing is the structural representation of engaging tooth engagement in the tooth that is provided with of the utility model gear ring outer wall and the mold endoporus.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Reduce the mold embodiment of gear ring quenching deformation shown in the accompanying drawing, mold is the flange-like member, and its main body is filled under the normal temperature state and installed in the gear ring endoporus that has heated, flange and gear ring choma running fit.Mold main body outer wall cooperates with gear ring internal tooth path in the utility model, and present embodiment gear ring internal diameter is Φ 222.5
0 + 0.29Mm allows distortion 0.10～0.20mm, and setting the interior back lash of mold and gear ring is 0.08～0.10mm.The mold plug installs in the gear ring that is heated to quenching temperature, and because of the gear ring heat expansion, mold is easy to fill in.Plug dress back gear ring quenches under the mold constraint, makes gear ring quenching deformation be controlled in deflection 0.1～0.15mm scope, and this deflection guarantees that ring gear is not overproof after quenching in allowed band.
The utility model is simple in structure, mounting or dismounting easily, it is supporting to be particularly suitable for small serial production.
