Abstract
The utility model provides an additional strengthening's axle sleeve. Its structure is opened at the outer wall intermediate position of substrate to have oiling groove, and it has the inlet port to open on oiling groove the axle sleeve inner wall has a copper sheathing with interference fit's mode casing pressure also open corresponding inlet port on the copper sheathing, it has a plurality of oily caves to bore on the copper sheathing inner wall, the oil cave degree of depth is less than the thickness of copper sheathing. The utility model discloses mode with the tight fit increases wear resistant copper sheathing layer for the wear resistance of axle sleeve inner wall is showing and is improving. Simultaneously, the oily cave of seting up on the copper sheathing layer for lubricating oil distributes evenly, and lubricated effect is better, thereby has reduced friction, vibration and noise, effective life who prolongs round pin axle and axle sleeve.
Description
Technical field
The utility model relates to a kind of sliding bearing part, and specifically a kind of have the axle sleeve strengthening structure, and this axle sleeve is arranged 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, can avoid because bearing pin (bucket spindle) directly contacts with car body and produce wearing and tearing, also effectively can reduce friction simultaneously, reduces vibration, reduce noise; The mounting hole of large forearm and scraper bowl and the corrosion resistance of bearing pin (bucket spindle) can also be improved.And, when breaking down, be convenient to dismounting, easy to maintenance.Existing axle sleeve wear-resisting property is poor, causes working life short, and, repair difficulty after the axle sleeve wall body wearing and tearing of metal material, cause scrappage high.The maintenance cost of excavator is remained high.
Model utility content
The purpose of this utility model is just to provide a kind of axle sleeve with reinforcement structure with good abrasion resistance, to improve the working life of axle sleeve.
The utility model is achieved in that
There is the axle sleeve strengthening structure, have oiling groove in the neutral position of base material outer wall, oiling groove has oil inlet hole, overlap in an interference fit at described sleeve lining and be pressed with copper sheathing, described copper sheathing also has corresponding oil inlet hole; Described copper sheathing inwall is drilled with multiple oily cave, and described oily acupoint depth is less than the thickness of described copper sheathing.
Axle sleeve of the present utility model is wear-resisting copper sheathing layer with the tactile internal face that is coupling, and this makes the wear-resisting property of sleeve lining significantly improve.Simultaneously, the oily cave that copper sheathing layer is offered, the memory space of sleeve lining to lubricant oil is increased greatly, and, be evenly distributed in sleeve lining face, make lubrication effect better, thus decrease friction, vibration and noise, it also avoid the situation that the local abrasion of sleeve lining face is uneven, and then effectively can extend the working life of 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 utility model has oiling groove 2 in the neutral position of axle sleeve base material 1 outer wall, oiling groove 2 has oil inlet hole 3, on the wall of base material 1 inner chamber, cover is pressed with copper sheathing 4 in an interference fit, this friction tight mode can make copper sheathing and base material be close together, shape and the axle sleeve base material inner wall surface shape of copper sheathing adapt, the through hole corresponding with oil inlet hole 3 on axle sleeve base material is had in the middle part of copper sheathing, this axle sleeve adds man-hour, first copper sheathing tensioner is affixed on base material internal surface, form wear-resisting inside liner, ecto-entad again, process oil inlet hole 3.Copper sheathing 4 inwall has multiple oily cave 5, and the degree of depth in oily cave 5 is less than the thickness of copper sheathing 4, and copper sheathing is that the copper material being 3-5mm by thickness is made.The processing in oil cave 5 is carried out before fitting with axle sleeve base material.
In the utility model, oily cave 5 is arranged in the both sides of oiling groove 2 symmetrically.Good mode of execution is arranged by row vertically in oily cave, and between each adjacent two row, oily cave is staggered.In side, adjacent two row are furnished with 3 and 4 oily caves respectively, thus realize staggered.This staggered mode makes the distribution of lubricant oil more even, lubrication effect is better, thus decrease friction, vibration and noise, a kind of mode of execution is preferably, oil 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, oil reserve can be increased; When oil reserve is identical, the degree of depth in oily cave can be shortened, thus improve the working strength of axle sleeve.
Originally there is the axle sleeve wear-resisting property strengthening structure good, longer service life.
Claims (1)
1. there is the axle sleeve strengthening structure, have oiling groove in the neutral position of base material outer wall, oiling groove has oil inlet hole, it is characterized in that, overlap in an interference fit at described sleeve lining and be pressed with copper sheathing, described copper sheathing also has corresponding oil inlet hole; Described copper sheathing inwall is drilled with multiple oily cave, and described oily acupoint depth is less than the thickness of described copper sheathing.
