Abstract
The utility model discloses a hoist wheel that flange part is hardened, include: it is straight to outside part to inside subtotal. Inside part is rotatory around the rotation axis, and it comprises the main part. Outside part has respective inside surface including a working face and first, two flanges, first, two flanges, and the inside surface of working face and flange has constituted the wearing parts of wheel. The inside separately of flange keeps toughness respectively, strengthens the main part of wheel, has strengthened the impact strength of flange. Extended and to the counterpart separately of every flange in the working face below by sclerosis part for every flange is hardened completely, improves the toughness and the wearability of wheel. The utility model discloses the problem and the beneficial effect that solve are: the wearing parts of selectivity sclerosis wheel, reduction in production cost, the toughness and the wearability of improvement wheel improve impact strength. Reduce material conversion volume in the hardening process, reduce the possibility of wheel thermal fragment line.
Description
Technical field
The utility model relates to a kind of wheel for overhead traveling crane thermomechanical components, is specifically related to the crane wheel that flange section is hardened, and improves resistance to abrasion and the toughness of wheel.
Background technology
As everyone knows, the continuous problem of crane locomotive foot wheel abrasion and fault is all subject to along the separation parallel orbit crane in bridge type travelled on wheel, at such crane in bridge type, wheel rolls along raceway surface, crane wheel part is contacted with raceway surface, thus makes this crane wheel part wears.Can be highly brittle after the flange of a crane wheel is completely hardened, reduce the overall strength under shock of flange, such wheel is more easily damaged.And flange region is when being hardened, thermal crack often occurs in the flange region of wheel, causes the major part of flange region to be separated wheel, causes wheel not operate, and be in a kind of situation of danger.
Utility model content
The technical problems to be solved in the utility model is the wearing part of selective sclerosing wheel, improves toughness and the resistance to abrasion of wheel, improves strength under shock.Reduce material converting amount in hardening process, reduce the possibility of wheel heat crackle, reduce productive costs.
In order to solve the problems of the technologies described above, the utility model employing technical scheme is: the crane wheel that flange section is hardened.
The crane wheel that flange section is hardened, comprising: a radial inner portion and a radially outer part.Described interior section rotates around S. A., and it is made up of main body.Described exterior section comprises a driving surface and first and second flange, and first and second flange has respective interior surface, and the interior surface of driving surface and flange constitutes the wearing part of wheel.The respective inside of first and second flange keeps toughness respectively, strengthens the main body of wheel, enhances the strength under shock of first and second flange.Be hardened part to extend below driving surface and to the respective corresponding part of first and second flange, cured section is a parabolic shape, and cured section is when heat treatment, the heat treatment degree of depth is maximum in the center of driving surface, reduce gradually towards first and second flange, cured section equals the half of first and second flange end thickness in the degree of depth of first and second flange end, makes first and second flange like this and non-fully is hardened, and improves toughness and the resistance to abrasion of wheel.
Advantage to be solved in the utility model and beneficial effect are: the wearing part of selective sclerosing wheel, improve toughness and the resistance to abrasion of wheel, improve strength under shock.Reduce material converting amount in hardening process, reduce the possibility of wheel heat crackle, reduce productive costs.
Accompanying drawing explanation
Accompanying drawing 1: the cross-sectional schematic of the crane wheel that flange section is hardened.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further: the crane wheel that flange section is hardened, comprises: a radial inner portion (1) and a radially outer part (2).Described interior section (1) rotates around S. A. (3), and it is made up of main body (4).Described exterior section (2) comprises a driving surface (5) and first and second flange (6,7), first and second flange (6,7) there is respective interior surface (6a, 7a), the interior surface (6a, 7a) of driving surface (5) and flange constitutes the wearing part of wheel.The respective inside (6b, 7b) of first and second flange (6,7) keeps toughness respectively, strengthens the main body (4) of wheel, enhances the strength under shock of first and second flange (6,7).Be hardened part (8) in the extension of driving surface (5) below and to first, two flanges (6, 7) respective corresponding part (6c, 7c), cured section (8) is a parabolic shape, and cured section (8) is when heat treatment, the heat treatment degree of depth is maximum in the center of driving surface (32), towards first, two flanges (6, 7) reduce gradually, cured section (8) is first, two flanges (6, 7) degree of depth of end equals first, two flanges (6, 7) half of end thickness, make first like this, two flanges (6, 7) and non-fully be hardened, improve toughness and the resistance to abrasion of wheel.
