Description
Technical field
The utility model belongs to bearing technical field of heat treatment, and in particular to carburizer is used in a kind of bearing ring heat treatment
Dress.
Background technology
To the bearing ring that raw material are mild steel, Carburization Treatment, mesh need to be carried out in heat treatment to improve material property
Preceding we carry out the heat treatment carburizing of double-row conical bearing lasso on double continuous gas carburizing production line, process fashionable dress
Material method is：Often disk fills two layers, every layer of inner ring of 4 outer rings 8（1 outer ring and 2 inner rings are placed in together to be a set of）, layer with
Separated with iron wire filter between layer, separated between the inner ring of set and outer ring with tripod, but existed in real work following
Several technical disadvantages：
1）Charging tray is separated with iron wire filter between layers so that ring face directly contacts with iron wire filter, in stove
In thorax at a high temperature of 930 DEG C or so, by lasso own wt（Outer ring substance 11.58Kg, inner ring substance 6Kg）Effect, lasso
End face easily produces iron wire impression.The especially outer ring of the bottom, is subjected to the weight of upper two layers lasso, and the end face of outer ring
Width relative narrower（Only 2~2.5mm）, this allows for easily producing deeper impression in end face in process, caused
Waste product is produced when grinding and processing.
2）Do not fix when lasso is placed on charging tray, easily slided in charging tray is with conveyer belt traveling process, made adjacent outer
The outer diameter contact of circle, cause contact site carburized layer shallower or without carburized layer.
3）Though separated between set Internal and external cycle with tripod, in charging tray in progradation, two inner rings and tripod
Still can arbitrarily it move about, inner ring large-flange external diameter easily contacts with outer ring raceway, causes outer raceway local carburzing layer shallower or nothing is oozed
Carbon-coating.
4）Inner ring can move about when travelling together with tripod, and the cusp on the outside of tripod can withstand on the central diameter of outer ring
On, easily cause central diameter card wound.
In summary, existing bearing ring heat treatment carburizing frock is to ensureing that the crudy of product has hidden danger, especially
It is that local carburzing layer occur shallower or when causing lasso entirety carburized layer uneven without carburized layer, the on the one hand phosphatization after mill is processed
When lasso surface piebald occurs, have a strong impact on product appearance quality；On the other hand carburized layer is measured after secondary quenching being influenceed
The accuracy of depth, if more seriously there is the region without carburized layer in the working face of lasso, to the service life of bearing with
And safe to use it can cause strong influence.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose that carburizer is used in a kind of bearing ring heat treatment
Dress.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
Carburizing frock is used in a kind of bearing ring heat treatment, and described carburizer's harness has every disk and to separate bearing ring
Inner ring, the tripod of outer ring；Described is the mesh type frame structure formed by casting heat resistant steel every disk；Every each described on disk
Grid in place a bearing ring, and four are each respectively provided with the grid to the bearing holder (housing, cover) that is placed on it every disk
The outer ring of circle carries out spacing annular groove；The outer ring of the bearing ring is located in the annular groove of corresponding grid, by annular groove
Internal diameter or external diameter the outer ring of bearing ring is carried out it is spacing；It is described to be provided with column I every the corner of disk, neighbouring two
Connected as one between disk by column I, and the height of the column I is more than the height of bearing ring.
Described tripod is welded by three fine steel ribs, and one end of the every fine steel rib has what bending formed
Arc section；The fine steel rib has summit of the one end as tripod of arc section, and the arc section institute of three finer wires
Shape diameter of a circle is more than the inner ring external diameter of bearing ring, less than the outer ring internal diameter of bearing ring；Described three drift angles of tripod
Inner side is respectively welded the column II set perpendicular to triangle；Three place diameter of a circles of column II are less than bearing ring
Inner ring internal diameter.
The utility model proposes a kind of bearing ring heat treatment carburizing frock, interlayer is designed as grid every disk
Formula, ensure that carburizing atmosphere fully circulates to reserve space as big as possible；4 annular grooves are designed with the grid every disk,
In order to avoid unicity occurs in frock, we design according to the outer ring of common several type products of processing for the size of annular groove,
The internal diameter of annular groove is slightly less than the age of a draught animal size of minimum outer ring, external diameter is slightly larger than the external diameter of maximum outer ring, and such annular groove can be with
It is adapted to several models general, when cycle surface is placed in annular groove, outer ring can be entered by the internal diameter or external diameter of annular groove
Row is spacing, makes it micro travelling in groove, so would not arbitrarily slide, avoid in charging tray is with conveyer belt traveling process
Outer diameter contact, which occurs, in adjacent outer ring causes carburized layer uneven；Meanwhile assigning 4 columns every four angles of disk, and with set
Cylinder and column coordinate branch overhang required for interlayer a height, make lasso upper surface and upside every disk keep space no longer connect
Touch, the space of each self-forming independence, the weight of itself need to only be undertaken by so allowing for lasso lower surface, be no longer influenced by upper strata lasso
The pressure of weight, avoid generation end face impression in carburizing process at high temperature；Under this configuration, when can be by carburizing simultaneously
It is three layers that often the lasso of disk, which puts quantity increase, to improve operating efficiency；The designed arc-shaped appearance at the cusp end of tripod ensure that not
Card can be caused to hinder to outer ring central diameter；
In summary, the utility model is relatively fixed position between the inner ring of a set of product and outer ring, is advanced in charging tray
During, it is ensured that uniform gap is remained between two inner rings and outer ring and between inner ring and inner ring, it is ensured that carburetted gas
Atmosphere fully circulates, and improves the uniformity of carburized layer.
