Product perpendicularity and levelness, make gear product be heat-treated in stabilization it is controllable, so as to reduce hot backgear contact zone noise, carry
Height engagement stationarity, extend the frock bin of the service life of gear.
Background technology
Change can all be produced to gear teeth face helical angle, pressure angle, the bounce of bearing footpath, transverse tooth thickness after gear heat treatment carburizing and quenching
Change, deformation too conference causes flank of tooth grinding difficult, has influence on the meshing performance and flank of tooth spot of the gear teeth, makes meshing noise value liter
Height, the abnormal sound of gear is caused early to grind.Therefore, strict control and stable heat treatment deformation, stable deformation energy is answered to improve engagement
Stationarity, circular tooth contact noise can be reduced, extend the service life of gear.
The machining accuracy before gear thermal, on the premise of Technology for Heating Processing solidification ensures, it is desirable to which gear is quenched in heat treatment carburizing
During fire, control deformation, ensure that gear shifting quadrant texturing is small, should set about from heat treatment material rest angle, control the change of heat treatment material rest
Shape, the process stability is lifted by the design to heat treatment material rest and improvement, and ideal use is not yet found by retrieval
In the versatility of control driving gear heat treatment deformation and turnable heat treatment tooling bin for use.
Utility model content
The purpose of this utility model is that gear can be deformed in heat treatment process in order to solve at this stage, is influenceed follow-up
The shortcomings that processing, and a kind of gear heat treatment frock bin of the raising gear NVH mass proposed.
To achieve these goals, the utility model employs following technical scheme：
A kind of gear heat treatment frock bin for improving gear NVH mass, including base, one group is connected on base and is stood
Bar, be connected at least one support bin between vertical rod, is socketed in each vertical rod between two neighboring support bin
One sleeve, one group of adapter is connected on each support bin.
On the basis of above-mentioned technical proposal, there can be technical scheme further below：
The base is a square framework, and each side of framework is formed by connecting by cross section for the plate of " Ω " shape.
The support bin is square framework, one group of cross bar and montant arranged in a crossed manner is provided with the inside of framework, every
The junction of individual cross bar and each montant is equipped with through hole, and an adapter is all connected with each through hole.
The adapter includes siphunculus, and one group of attachment strap is provided with the outside of siphunculus.
One group of screw is provided with the base, screw rod is equipped with the downside of each vertical rod, each screw rod is right
It should be connected in corresponding screw.
The utility model has the advantage of：The present apparatus is simple in construction, in light weight, easy to disassemble, versatility is good, and base can
Upset, is effectively guaranteed flatness, each part is made of medium temperature wax hot investment casting, its any surface finish, and charging tray surface is thick
Rugosity is good, and precision is high, and each part uses " Ω " shape structure, reduces stress deformation in heating process, reduces driving gear and add
The charging tray external force of thermal process influences the heat treatment deformation of gear；Support bin universal hole to ensure appropriate distance, avoid between workpiece
Collide with and deform；The positive and negative design of base is the same, can arbitrarily may be reversed, increase service life, ensure the stability of product,
The cost of buying bin is saved simultaneously；Private adapter is used on support bin, reduces body supports bin input, difference production
Product need to only select private adapter, ensure the versatility of main body material frame structure, different product adapter selectivity, ensure all productions
It is stable in product heat treatment process；Stacked by the reasonable cooperation of the support of driving gear and adapter, the smooth of support, bin
Perpendicularity, the cycle of bin are easier to control using stable, deformation；Easily taken by light adapter driving gear and easily put, kept away
Matter weight body supports bin free of replacement, reduces operator's labor intensity；The use of this heat treatment tooling avoids gear heat treatment
Between collide with, control and the heat treatment deformation of stable gear, protect hot the post-processing precision and roughness of the flank of tooth, reduce gear
Contact zone noise, engagement stationarity is improved, extend the service life of gear, while the universal two sides design structure combined improves
The life-span of bin.
