Abstract
The utility model discloses a kind of axle sleeve, including the axial cross section of outer annular groove is symmetrical hexagon on axle sleeve, and the area of hexagon is more than the area of former isosceles trapezoid.The utility model causes outer annular groove axial cross section in the case where ensureing that base angle do not increase, increasing section area, reduction lubricating grease by resistance, after reduction lubricant thickening can not grease up possibility, improve the reliability of linkage.
Description
Technical field
The utility model is related to a kind of axle sleeve, belongs to technical field of engineering machinery.
Background technology
At present, axial rotation is realized usually through axle sleeve in linkage.Existing axle sleeve, is designed generally on the outside of bearing
There is outer annular groove, to form lubricating grease passage.As shown in figure 4, the outer annular groove axial cross section of existing axle sleeve is generally isosceles
Trapezoidal, its base angle size is directly proportional to gland resistance, is directly proportional to outer annular groove area of section；Its go to the bottom edge lengths b and stress
Be directly proportional, high h is inversely proportional with bearing intensity, therefore for the ease of gland, the base angle of outer annular groove axial cross section isosceles trapezoid, under
Base b, high h should not open up excessive, but therefore can cause that outer annular groove axial cross section area is small, and lubricating grease resistance is larger.In addition,
If user's long period not grease up, lubricating grease is easily thickened, lubricating grease stopping up of oil channel when serious, lead to not plus
Note.Oil reserve is less, abrasion aggravation.
The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides outer annular groove axial direction on a kind of axle sleeve, axle sleeve
Area of section increases, and can improve the throughput of lubricating grease, is effectively increased oil reserve, reduces abrasion, and then improve linkage
Reliability.
To achieve these goals, the axial cross section of outer annular groove is on a kind of axle sleeve that the utility model is used, axle sleeve
Symmetrical hexagon, the area of the hexagon is more than the area of former isosceles trapezoid.
Preferably, the hexagon be on the basis of former isosceles trapezoid, the waist of isosceles trapezoid is changed into two sections of broken lines and
Into upper and lower base is parallel, and high size keeps constant.
Preferably, the angle at the hexagon base angle is less than or equal to the base angle of former isosceles trapezoid.
Preferably, hexagon bottom edge lengths keep constant or reduced.
Compared with prior art, the section of the outer annular groove structure of the utility model axle sleeve is hexagon, is not increasing pressure
Resistance is covered, in the case of reducing bearing intensity, increases the logical of lubricating grease in outer annular groove area of section, increase unit section area
It is excessive, increase oil reserve, reduce abrasion, improve the reliability of linkage.

Fig. 1 is the schematic diagram of the utility model axle sleeve outer annular groove structure；
Fig. 2 is Fig. 1 section close-up schematic view example one；
Fig. 3 is Fig. 1 section close-up schematic view example two；
Fig. 4 is the former section close-up schematic view for commonly using axle sleeve outer annular groove structure.
In figure：1st, outer annular groove, α, base angle, h, height, a, upper bottom edge, b, bottom, the angle between β, broken line.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, the axial cross section of outer annular groove 1 is symmetrical hexagon on a kind of axle sleeve, axle sleeve, described
The area of hexagon is more than the area of former isosceles trapezoid.By increasing section area, lubricating grease is reduced by resistance, is reduced
After lubricant thickening can not grease up possibility, improve the reliability of linkage.
Preferably, the hexagon be on the basis of former isosceles trapezoid, the waist of isosceles trapezoid is changed into two sections of broken lines and
Into upper and lower base is parallel, and high size keeps constant.Hexagon after improvement is still symmetrical relative to former isosceles trapezoid line of symmetry.
Wherein, the angle between two sections of broken lines is not fixed.
Preferably, the angle at the hexagon base angle is less than or equal to the base angle of former isosceles trapezoid, now, may be such that outer shroud
The axial cross section of shape groove 1 is ensureing base angle in the case where α does not increase, increasing section area, reduces lubricating grease and passes through resistance, drop
After low lubricant thickening can not grease up possibility, improve the reliability of linkage.
Preferably, hexagon bottom edge lengths keep constant or reduced.
Embodiment one
This example chooses axle sleeve outer annular groove structure, and its axial cross section is hexagon, as shown in Fig. 2 wherein base angle, height h
With bottom b size constancies, α=15 °, h=1mm, b=10.5mm；Upper bottom edge size increase a1=8mm (full size a=
7mm)；Angle β=156.3 ° between two broken lines.Outer annular groove mouthful and axle sleeve rounding R=2mm.Comparison diagram 2 and Fig. 4 are visible, should
The area of hexagon is more than the area of former isosceles trapezoid.
Embodiment two
This example chooses axle sleeve outer annular groove structure, and its axial cross section is hexagon, as shown in figure 3, wherein height h sizes are not
Become, base angle diminishes α 1=25 ° (full size α=30 °), bottom b sizes diminish b1=10mm (full size b=10.5mm)；On
Base size increase a1=8.6mm (full size a=7mm)；Angle β=131.5 ° between two broken lines.Outer annular groove mouthful and axle sleeve
Rounding R=2mm.Comparison diagram 3 and Fig. 4 are visible, and the area of the hexagon is more than the area of former isosceles trapezoid.
In the utility model the base angle of outer annular groove axial cross section, height and bottom respectively with gland when the resistance that is subject to
Power, axle sleeve intensity are inversely proportional.Therefore in the case where not increasing base angle, height and bottom, increasing section area improves lubrication
The throughput of fat, is effectively increased oil reserve, reduces abrasion, improves the reliability of linkage.
