Abstract
The utility model discloses a solid lubricating copper base bearing with a groove structure. The solid lubricating copper base bearing comprises a base body made of copper alloy, wherein a lubricating layer is also arranged at the inner surface of the base body; intersected inclined grooves are also arranged on the inner-diameter surface of the base body; the inclined grooves can be in a spiral structure; the copper alloy can select high-strength brass alloy of which the hardness is greater than 260HB; a solid lubricating gent is molybdenum disulfide and tungsten disulfide; the intersection angles of the inclined grooves are 45-70 degrees; the intervals of the fine grooves are 3-6mm. By adopting the solid lubricating copper base bearing with the groove structure disclosed by the utility model, abrasion or breakage of a sliding surface of an inner-diameter section caused by sundries can be prevented to the maximal extent; the service life of the bearing is prolonged; the wearing properties are improved; the lubricating property of the bearing is also improved.
Description
Technical field
The utility model relates to a kind of slip copper base bearing, especially a kind of solid lubrication copper base bearing with the stria structure.
Background technique
Because industrial vehicles such as excavator, wheel type excavator all use in rugged environment at present, have very high corrosion resistance and wear resistance etc. with regard to requiring the bearing in its rotation structure knot part; Existing steel bushing easily gets rusty and corrodes, and the copper sheathing tank structure is simple, and the two all is not easy the high material of the hardness such as the grains of sand that enter is discharged lubricated face, quick abrasion, and the life-span is short.
Summary of the invention
The purpose of this utility model is that design for the deficiency that solves above-mentioned technology a kind of can discharge the high hardness material lubricated face, reduces wear and improves the solid lubrication copper base bearing of the band stria structure in life-span.
The solid lubrication copper base bearing of the band stria structure that the utility model is designed comprises the matrix of being made by Cuprum alloy, also is provided with lubricating layer at the matrix internal surface, also is provided with the skewed slot that intersects to form on the matrix inside diameter surface; Described skewed slot can be sped structure; Cuprum alloy can be selected high-strength brass alloy for use, and hardness is greater than 260HB; Lubricating layer is solid lubricant, and solid lubricant can be molybdenum disulfide (MoS2) or tungsten disulfide (WS2), also can be both mixtures; During use, utilize skewed slot the foreign material that enter between internal diameter and the axle can be discharged to the inside diameter both sides; When particularly adopting the spiral skewed slot that intersects to form, more can easily foreign material be taken out of along skewed slot.
In addition, the molybdenum disulfide (MoS2) that the matrix internal surface of bearing sprays, tungsten disulfide solid lubricant coatings such as (WS2), lubriation material can be stored in the skewed slot, can easily lubriation material fully be delivered to slip surface in the course of the work again, play good lubrication, at this, its thickness of described lubricating layer usually can be more than 0.015mm.
As preferably: the skewed slot intersecting angle can be between 45 ° to 75 °, and the spacing of skewed slot is 3 to 6mm, can store lubricant oil in this scheme skewed slot, has higher antiwear characteristic.
The solid lubrication copper base bearing of the band stria structure that the utility model is designed, its beneficial effect is: the slip surface that can prevent the inside diameter that foreign material cause to greatest extent is worn or breakage, increases the working life of bearing, and by higher antiwear characteristic; Improved the lubrication property of bearing more.
Description of drawings
Fig. 1 is embodiment 1 bearing integral structural representation;
Fig. 2 is embodiment 2 partial enlarged view.
Among the figure: matrix 1, lubricating layer 2, skewed slot 3.
Embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, the solid lubrication copper base bearing of the described band stria of present embodiment structure comprises the matrix of being made by Cuprum alloy 1, also is provided with lubricating layer 2 at matrix 1 internal surface, also is provided with the skewed slot 3 that intersects to form on matrix 1 inside diameter surface; Described skewed slot 3 is sped structure, can certainly not be sped structure; The Cuprum alloy of matrix 1 can be that hardness is greater than the high-strength brass alloy of 260HB; Lubricating layer 2 is solid lubricant, and solid lubricant can be molybdenum disulfide (MoS2), tungsten disulfide (WS2), and the thickness of its lubricating layer is more than the 0.015mm.
During use, utilize the spiral skewed slot that intersects to form that the foreign material that enter between internal diameter and the axle are discharged to the inside diameter both sides.The solid lubrication copper base bearing benefit compared with prior art of the described band stria of present embodiment structure is: the utility model can prevent to greatest extent that the slip surface of the inside diameter that foreign material cause is worn or breakage, increases the working life of bearing; Improved the lubrication property of bearing more.
Embodiment 2:
As shown in Figure 2, the solid lubrication copper base bearing of the described band stria of present embodiment structure, as different from Example 1: the intersecting angle of skewed slot 3 is between 45 ° to 75 °, and the spacing of skewed slot 3 is 3 to 6mm.The solid lubrication copper base bearing of the described band stria of present embodiment structure is compared with embodiment 1 and also to be had following advantage: can store lubricant oil in this scheme skewed slot, have higher antiwear characteristic.
