Abstract
The utility model discloses the abrasion-proof mechanism in a kind of excavator turntable hinge hole, swing arm assembly (1) and turntable (2) are flexibly connected by bearing pin (3), in the upper hinge holes forming two receivings bearing pin (3) of turntable (2), it is characterized in that, the hinge hole of turntable (2) is all assembled a lining (5) can being sheathed on bearing pin (3)；In hinge hole, a dust ring (6) can being sheathed on bearing pin (3) is assembled at the two ends of each lining (5) respectively；It is provided with in bearing pin (3) and the lubricating cup (4) of one receiving lubricating oil can be set by the through lubrication channel to lining (5) inner surface in bearing pin (3) end, the lubrication channel porch of bearing pin (3) end.Abrasion-proof mechanism of the present utility model makes the contact surface of bearing pin and turntable be become lubrication friction from dry friction, effectively prevent the abrasion of hinge hole.
Description
Technical field
This utility model relates to the abrasion-proof mechanism in a kind of excavator turntable hinge hole, belongs to mechanical field.
Background technology
Owing to the hardness in turntable hinge hole is well below bearing pin case hardness, through long dry friction, turntable hinge hole easily produces abrasion, turntable hinge hole after abrasion can cause equipment to rock, cannot normally work, once wearing and tearing in turntable hinge hole, keeps in repair extremely difficult, need to remove equipment, to the hinge hole again extensive work such as built-up welding, machining.
Summary of the invention
The problem existed for above-mentioned prior art, this utility model provides the abrasion-proof mechanism in a kind of excavator turntable hinge hole.
To achieve these goals, the technical solution adopted in the utility model is:
The abrasion-proof mechanism in excavator turntable hinge hole, swing arm assembly (1) and turntable (2) are flexibly connected by bearing pin (3), in the upper hinge holes forming two receivings bearing pin (3) of turntable (2), it is characterized in that, the hinge hole of turntable (2) is all assembled a lining (5) can being sheathed on bearing pin (3)；In hinge hole, a dust ring (6) can being sheathed on bearing pin (3) is assembled at the two ends of each lining (5) respectively；It is provided with in bearing pin (3) and the lubricating cup (4) of one receiving lubricating oil can be set by the through lubrication channel to lining (5) inner surface in bearing pin (3) end, the lubrication channel porch of bearing pin (3) end.
Lining (5) with interference fit in the hinge hole of turntable (2).
Bearing pin (3) end is machined with the screwed hole of assembling lubricating cup (4).
Lubrication channel is arranged at the axle center of bearing pin (3), and vertical central extends to lining (5).
The inner surface of lining (5) is provided with oil groove.
Lubrication channel leads in the oil groove of lining (5) inner surface.
The beneficial effects of the utility model are: the contact surface of bearing pin and turntable is become lubrication friction from dry friction, effectively prevent the abrasion of hinge hole, it is to avoid carry out hinge hole removing maintenance.

In figure: 1, swing arm assembly, 2, turntable, 3, bearing pin, 4, lubricating cup, 5, lining, 6, dust ring, 7, screw bolt and nut.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: lining 5 with interference fit on turntable 2, two ends assembling dust ring 6, swing arm assembly 1 and turntable 2 are coupled by bearing pin 3, and fixed by bolt and nut 7, bearing pin 3 end is threaded hole, axle center processing and lubrication passage, in order to assemble lubricating cup 4, and delivers lubricating oil in the oil groove of lining.Dust ring 6 prevents extraneous dust from entering in the gap of lining 5 and bearing pin 3, in order to avoid pollution lubricating is oily.
In installation process, by a dust ring from press-in turntable hinge hole, upper end shown in Fig. 2 to appropriate location, by lining 5 from the press-in turntable of upper end shown in Fig. 2 to dust ring upper surface, then second dust ring is pressed into lining upper surface, completing the parts assembling in hinge hole, upper end, hinge hole, lower end is ibid.Bearing pin sequentially passes through bush hole, swing arm assembly, bush hole to aliging with the stop sleeve on turntable, screw bolt and nut 7 be fixed on turntable 2 by bearing pin 3.Finally lubricating cup 4 is assembled to bearing pin 3 end face.
