Abstract
The utility model provides a big forearm of excavator is connected with scraper bowl and is used axle sleeve. It has oiling groove to open at the outer wall intermediate position of substrate, and it has the inlet port to open on oiling groove, the oily cave of having arranged on the inner wall, characterized by, arrange according to row along the axial in the oil cave, two adjacent oily caves are crisscross arranges. The utility model discloses an arranging according to row along the axial in the oil cave, just two adjacent oily caves are crisscross arranges, and this makes the distribution of lubricating oil more even, and lubricated effect is better to reduced friction, vibration and noise, the life of axle and axle sleeve is sold in effective extension.
Description
Technical field
The utility model relates to a kind of sliding bearing part, and specifically the large forearm of a kind of excavator is connected with scraper bowl with axle sleeve, and this axle sleeve is installed on the large forearm of excavator and scraper bowl joint, can change.
Background technique
Axle sleeve is arranged on the large forearm of excavator and scraper bowl joint, not only can avoid because bearing pin (bucket spindle) directly contacts with car body and produce wearing and tearing; And effectively can reduce friction, reduction vibration, minimizing noise; The mounting hole of large forearm and scraper bowl and the corrosion resistance of bearing pin (bucket spindle) can also be improved.In addition, when breaking down, be convenient to dismounting, convenient for maintaining.Existing axle sleeve wear-resisting property is poor, causes working life shorter, and, repair difficulty after the axle sleeve wall body wearing and tearing of metal material, cause scrappage high.The use of excavator and maintenance cost are remained high.
Model utility content
The purpose of this utility model is just to provide the large forearm of a kind of excavator and is connected with scraper bowl with axle sleeve, to solve the problem of sleeve lining lubricant oil skewness.
The utility model is achieved in that
The large forearm of excavator is connected with scraper bowl with axle sleeve, has oiling groove, oiling groove has oil inlet hole in the outer wall neutral position of base material; Inwall is placed with oily cave, described oily cave is vertically by row arrangement, and the described adjacent two oily caves of row are staggered.
Under technique scheme, the utility model can realize like this:
Described oily cave is cylindrical flat cave.
Described oily cave is arranged in the both sides of oiling groove symmetrically; Every side, the oily cave number in the two adjacent oily caves of row is respectively three and four oily caves, and in staggered.
Arrange by row vertically in oily cave of the present utility model and the adjacent two oily caves of row are staggered, and this makes the distribution of lubricant oil more even, and lubrication effect is better, thus decreases friction, vibration and noise, effective working life extending bearing pin and axle sleeve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the large forearm of excavator is connected with scraper bowl and has oiling groove 2 with the neutral position of axle sleeve base material 1 outer wall, and oiling groove 2 has oil-feed through hole 3; Inwall has multiple cylindrical oily cave 4, oily cave is vertically by row arrangement, and between each adjacent two row, oily cave is staggered.Specifically, oily cave 4 is arranged in the both sides of oiling groove 2 symmetrically.In side, adjacent two row are furnished with three and four oily caves respectively, thus realize staggered.A kind of mode of execution is preferably that oily cave 4 is cylindrical structural, and the bottom surface in oily cave 4 is flat, adopts this structure, under the prerequisite that oily acupoint depth is identical, can increase oil reserve; When oil reserve is identical, the degree of depth in oily cave can be shortened, thus improve the working strength of axle sleeve.
Claims (3)
1. the large forearm of excavator is connected with scraper bowl with an axle sleeve, has oiling groove, oiling groove has oil inlet hole in the outer wall neutral position of base material; Inwall is placed with oily cave, it is characterized in that, described oily cave is vertically by row arrangement, and the described adjacent two oily caves of row are staggered.
2. the large forearm of excavator according to claim 1 is connected with scraper bowl with axle sleeve, and it is characterized in that, described oily cave is cylindrical flat cave.
3. the large forearm of excavator according to claim 1 is connected with scraper bowl with axle sleeve, and it is characterized in that, described oily cave is arranged in the both sides of oiling groove symmetrically; Every side, the oily cave number in the two adjacent oily caves of row is respectively three and four oily caves, and in staggered.
