For achieving the above object, a kind of articulated mounting, comprise link, hinged ear, bearing and bearing pin, link is provided with the first mounting hole, and hinged ear is provided with the second mounting hole; First mounting hole comprises the first via hole, the first receiving hole and first that communicate successively and dodges hole; The diameter of the first receiving hole is greater than the diameter of the first via hole, the first small stair face is formed between first receiving hole and the first through hole, first diameter of dodging hole is greater than the diameter of the first receiving hole, and first dodges between hole and the first receiving hole and be formed with first step surface; Bearing is arranged in the first receiving hole, a bearing outer ring wherein end face is kept out by the first small stair face, dodge hole first and be provided with the first draw-in groove near first step surface, the first draw-in groove is equipped with the first described snap ring, and the first snap ring withstands the other end of bearing outer ring; Bearing pin dodges hole through the second mounting hole, the first via hole, bearing and first.
Above-mentioned articulated mounting, bearing installs rear the first small stair face and the first snap ring of utilizing and carries out spacing to the end face of bearing, therefore, can locate more accurately bearing, also can prevent bearing from moving in the first mounting hole.Due to be provided with diameter larger first dodge hole, first diameter of dodging hole is greater than the external diameter of bearing, therefore, in installation bearing process, what first bearing entered first dodges hole and directly can not be pressed in the first receiving hole with bearing generation sliding friction, reduce the stroke of bearing installation process middle (center) bearing and the first mounting hole contact friction, reduce the difficulty that bearing is installed, the bearing in reduction bearing installation process and the wearing and tearing of the first mounting hole hole wall.
Further, be respectively equipped with hinged ear in the both sides of link, between link and hinged ear, have gap; One end of bearing pin has head, bearing pin one end relative with head dodges the second mounting hole of hole and another hinged ear successively through the second mounting hole of a wherein hinged ear, the first via hole, bearing, first, the outside that bearing pin is positioned at another hinged ear is provided with nut.Utilize head to prevent bearing pin from passing, by nut check bearing pin, prevent bearing pin axial float.
Further, bearing pin is provided with end ring between bearing inner race and hinged ear.Reduction bearing and hinged ear rigidity rub.
Further, bearing pin is provided with stainless steel gasket between another hinged ear and nut.
Further, two opposed ends of stainless steel gasket extend to nut lateral bend, and the stainless steel gasket of this structure has elastic force to nut, and nut locking can be allowed more firm.
Further, the both sides of hinged ear are respectively equipped with boss, and boss is provided with the 3rd mounting hole communicated with the second mounting hole, and boss can improve the intensity of hinged ear.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1, articulated mounting comprises link 1, hinged ear 2, bearing 3, bearing pin 4, nut 5, end ring 6 and stainless steel gasket 7.
Link 1 has the first mounting hole 11.First mounting hole 11 comprises the first via hole, the first receiving hole and first that communicate successively and dodges hole; The diameter of the first receiving hole is greater than the diameter of the first via hole, the first small stair face is formed between first receiving hole and the first through hole, first diameter of dodging hole is greater than the diameter of the first receiving hole, and first dodges between hole and the first receiving hole and be formed with first step surface.
Be respectively equipped with hinged ear 2 in the both sides of link 1, between hinged ear 2 and link 1, have gap.Hinged ear 2 has the second mounting hole 21.The both sides of hinged ear 2 are respectively equipped with boss 8, and boss 8 is provided with the 3rd mounting hole communicated with the second mounting hole 22, and boss 8 can improve the intensity of hinged ear.
Bearing 3 is arranged in the first receiving hole, a bearing outer ring wherein end face is kept out by the first small stair face, dodge hole first and be provided with the first draw-in groove near first step surface, the first draw-in groove is equipped with the other end that the first described snap ring 9, first snap ring 9 withstands bearing outer ring.Adopt this structure, bearing 3 installs rear the first small stair face and the first snap ring of utilizing and carries out spacing to the end face of bearing 3, therefore, can locate more accurately bearing 3, also can prevent bearing 3 from moving in the first mounting hole.Due to be provided with diameter larger first dodge hole, first diameter of dodging hole is greater than the external diameter of bearing, therefore, in installation bearing 3 process, what first bearing 3 entered first dodges hole and can not with bearing 3, sliding friction occur and directly be pressed in the first receiving hole, reduce the stroke of bearing 3 installation process middle (center) bearing and the first mounting hole contact friction, reduce the difficulty that bearing 3 is installed, the bearing 3 in reduction bearing 3 installation process and the wearing and tearing of the first mounting hole hole wall.
