Description
Technical field
The utility model relates to technical field of bearing processing, and in particular to a kind of spherical structure idler wheel Contact stress cubing.
Background technique
Spherical structure roller bearing Contact stress inspection method all causes dispute all the time, and original method is wire cutting ditch
Position template measures ditch position, as shown in Figure 1, this procedure inspection of radius of curvature is but ignored, ditch position template R uses the limit
Lower difference design does not have measurement radius of curvature requirement.Therefore often curvature is all based on negative for convenience when turning, not in drawing
Range is affected to grinding, such as surplus increases.
Utility model content
To solve the above problems, design is reasonable, structure the utility model proposes a kind of spherical structure idler wheel Contact stress cubing
Think it is ingenious, by curvature R piece measure bearing roller ditch curvature in the margin of tolerance of standard curvature.
A kind of spherical structure idler wheel Contact stress cubing, it includes two curvature R pieces, and curvature R piece is disk, one of them
The excircle dimension of curvature R piece is difference R1 in the limit of idler wheel ditch, and the excircle dimension of another curvature R piece is under the limit of idler wheel ditch
Poor R2, the R1 > R2.
Above-mentioned technical proposal is improved further and is refined, the centre of two curvature R pieces is welded to connect by steelframe.
Above-mentioned technical proposal is improved further and is refined, the processing method of the curvature R piece:
(1) column steel billet is chosen as material, and by column steel billet integral quenching.
(2) quenched column steel billet is clamped on grinding machine, by grinding machine, so that column steel billet peripheral dimension etc.
In curvature R piece peripheral dimension.
(3) column steel billet after grinding is clamped on wire cutting machine tool again, is divided column steel billet by wire cutting machine tool
Several thin slices are cut into, thin slice is curvature R piece.
A method of bearing roller ditch curvature, the standard curvature of bearing roller ditch are detected using above-mentioned radius of curvature cubing
For R, go out idler wheel ditch using numerically controlled lathe Milling Machining, the bearing roller ditch curvature is R, it includes the following steps:
(1) the curvature R piece that excircle dimension is R1 is placed in bearing roller ditch, range estimation compares R1 and R.
(2) the curvature R piece that excircle dimension is R2 is placed in bearing roller ditch, range estimation compares R2 and R.
(3) if R1 >=R ' >=R2, R ' R the margin of tolerance；Conversely, then R ' is not in the margin of tolerance of R.
The curvature that idler wheel ditch is detected by radius of curvature cubing, measures bearing roller ditch curvature R ' in the public affairs of standard curvature R
In poor range, then the subsequent grinding allowance of idler wheel ditch of bearing is small, high in machining efficiency；Bearing roller ditch curvature R ' is measured not in standard
In the margin of tolerance of curvature R, the parameter setting of this process numerically controlled lathe is accordingly modified, processes the idler wheel ditch of bearing.
The utility model advantage is that design rationally, is skillfully constructed, and measures bearing roller ditch curvature by curvature R piece and is marking
In the margin of tolerance of quasi- curvature, to reduce the grinding allowance of subsequent processing microstoning idler wheel ditch, production efficiency, section are improved
About production cost.

Column steel billet 1, curvature R piece 2, steelframe 3, bearing outer ring 4 in figure.
Specific embodiment
Such as Fig. 2-3, shown in Fig. 5, a kind of spherical structure idler wheel Contact stress cubing, it includes two curvature R pieces 2, curvature R
Piece 2 is disk, and the excircle dimension of one of curvature R piece 2 is the outer circle of difference R1, another curvature R piece 2 in the limit of idler wheel ditch
Difference R2, the R1 > R2 under the limit having a size of idler wheel ditch；The centre of two curvature R pieces 2 is welded to connect by steelframe 3.
As shown in figure 4, the processing method of the curvature R piece:
(1) it chooses column steel billet 1 and is used as material, and by 1 integral quenching of column steel billet.
(2) quenched column steel billet 1 is clamped on grinding machine, by grinding machine, so that 1 peripheral dimension of column steel billet
Equal to curvature R piece peripheral dimension.
(3) column steel billet 1 after grinding is clamped on wire cutting machine tool again, by wire cutting machine tool by column steel billet 1
Several thin slices are divided into, thin slice is curvature R piece 2.
Such as Fig. 6, a method of bearing roller Contact stress, bearing roller ditch are detected using above-mentioned radius of curvature cubing
Standard curvature be R, go out idler wheel ditch using numerically controlled lathe Milling Machining, the bearing roller ditch curvature is R, it includes following step
It is rapid:
(1) the curvature R piece 2 that excircle dimension is R1 is placed in bearing roller ditch, range estimation compares R1 and R.
(2) the curvature R piece 2 that excircle dimension is R2 is placed in bearing roller ditch, range estimation compares R2 and R.
(3) if R1 >=R ' >=R2, R ' R the margin of tolerance；Conversely, then R ' is not in the margin of tolerance of R.
Due to the finiteness of literal expression, and objectively there is unlimited specific structure, for the common of the art
For technical staff, without departing from the principle of this utility model, several improvement, retouching or variation can also be made,
Above-mentioned technical characteristic can be combined in the right way；These improve retouching, variation or combination, or it is not improved will be real
Other occasions are directly applied to novel conception and technical scheme, are regarded as the protection scope of the utility model.
