Abstract
The utility model relates to a kind of bearing roller, proposes a kind of taper datum end face tapered roller.The outer round surface (5) of a kind of taper datum end face tapered roller proposed is conical surface; The small end face (7) of tapered roller is plane; The large end face of described tapered roller is taper datum end face (3), and described taper datum end face (3) is conical surface; The middle part of taper datum end face (3) has depression 1, and is circular arc chamfering I (2) between depression (1) and taper datum end face (3); It is circular arc chamfering II (4) between taper datum end face (3) and outer round surface (5).The utility model increases the area of contact of tapered roller large end face and lasso large-flange, improves the axial carrying capacity of tapered roller, decreases the wearing and tearing of tapered roller large end face and lasso large-flange, improves the working life of bearing.
Description
Technical field
The utility model relates to a kind of bearing roller, particularly relates to a kind of taper datum end face tapered roller.
Background technique
The tapered roller used in existing tapered roller bearing, its big end surface is spherical; This surface is all the reference level of axially locating when adding man-hour and work, usually it is called spherical datum end face; Operationally, the spherical datum end face of tapered roller contacts with the large-flange of inner ring, bears thrust load.Because the contact form of the spherical datum end face of tapered roller and the large-flange of inner ring is point cantact, area of contact is very little, and therefore axial carrying capacity is restricted; In addition, there is larger friction between the spherical datum end face of tapered roller and inner ring large-flange, under point cantact situation, wearing and tearing are very fast, affect the working life of bearing.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model proposes a kind of taper datum end face tapered roller.
The utility model adopts following technological scheme for completing above-mentioned purpose:
A kind of taper datum end face tapered roller, the outer round surface of described tapered roller is conical surface; The small end face of described tapered roller is plane; The large end face of described tapered roller is taper datum end face, and described taper datum end face is conical surface; The middle part of described taper datum end face has depression, and is circular arc chamfering I between depression and taper datum end face; It is circular arc chamfering II between taper datum end face and outer round surface.
It is circular arc chamfering III between the small end face of described tapered roller and outer round surface.
The plain line of described taper datum end face is the straight line with certain convexity, and convexity amount is 3 ~ 5 μm.
The utility model proposes a kind of taper datum end face tapered roller, the large end face of tapered roller adopts conical surface, at Bearing inner, the contact of tapered roller and inner ring large-flange is made to become linear contact lay from point cantact, increase the area of contact of tapered roller large end face and lasso large-flange, thus improve the axial carrying capacity of tapered roller, decrease the wearing and tearing of tapered roller large end face and lasso large-flange, improve the working life of bearing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. depression, 2. circular arc chamfering I, 3. taper datum end face, 4. circular arc chamfering II, 5. outer round surface, 6. circular arc chamfering III, 7. small end face.
Embodiment
In conjunction with the drawings and Examples provided, the utility model is illustrated.
As shown in Figure 1, a kind of taper datum end face tapered roller, the outer round surface 5 of described tapered roller is conical surface; The small end face 7 of described tapered roller is plane; The outer round surface 5 of described tapered roller is being working surface, and the small end face 7 of described tapered roller is non-working surface; Be circular arc chamfering III 6 between the small end face 7 of described tapered roller and outer round surface 5; The large end face of described tapered roller is taper datum end face 3, and described taper datum end face 3 is conical surface, and the plain line of taper datum end face 3 is the straight line with certain convexity, in order to reduce the wall and corner effect produced when taper datum end face 3 contacts with inner ring large-flange; The maximum axial that the convexity amount of the plain line of the taper datum end face of described tapered roller is born according to roller is determined, general control is within the scope of 3 ~ 5 μm; The middle part of described taper datum end face 3 has depression 1, and is circular arc chamfering I 2 between depression 1 and taper datum end face 3; It is circular arc chamfering II 4 between taper datum end face 3 and outer round surface 5.
Claims (2)
1. a taper datum end face tapered roller, the outer round surface (5) of described tapered roller is conical surface; The small end face (7) of described tapered roller is plane; It is characterized in that: the large end face of described tapered roller is taper datum end face (3), and described taper datum end face (3) is conical surface; The middle part of described taper datum end face (3) has depression (1), and is circular arc chamfering I (2) between depression (1) and taper datum end face (3), is circular arc chamfering II (4) between taper datum end face (3) and outer round surface (5).
2. a kind of taper datum end face tapered roller according to claim 1, is characterized in that: the plain line of described taper datum end face (3) is the straight line with certain convexity, and the convexity amount of plain line is 3 ~ 5 μm.
