Embodiment
Consult Fig. 3 and Fig. 4, the utility model embodiment articulated elements comprises outer free bearing 1, a pair of axle sleeve 2, interior free bearing 3, bearing 4 and coupling shaft 5.
Outer free bearing 1 comprises that the first pedestal 10 and interval be fixed in a pair of the first support arm 11 on the first pedestal 10.All offer the first through hole 12 on the first support arm 11.The cross section that is opened in the first through hole 12 of two first support arms 11 is the centerline collineation setting of circular and two first through holes 12.
It is interior and relative fixing with the first support arm 11 with removably that a pair of axle sleeve 2 is arranged at respectively the first through hole 12.Offer the second through hole 20 on the axle sleeve 2.The center line of the second through hole 20 overlaps mutually with the center line of the first through hole 12.
Interior free bearing 3 comprises the second pedestal 30 and is fixed in the second support arm 31 on the second pedestal 30.Offer third through-hole 32 on the second support arm 31.After the assembling, the second support arm 31 between a pair of the first support arm 11, the central lines of the center line of third through-hole 32 and the second through hole 20.
By above-mentioned assembling mode, outer free bearing 1, axle sleeve 2 and coupling shaft 5 are fixedly connected with and mutual motion can occur each other, and interior free bearing 3 can rotate relative to coupling shaft 5 by bearing 4.
Wherein, the diameter of the first through hole 12 is greater than the external diameter setting of bearing 4.When articulated elements in use need to be safeguarded because of bearing 4 faults, take off coupling shaft 5 and axle sleeve 2, because of the diameter of the first through hole 12 external diameter greater than bearing 4, then can will finish dismounting and the installation of bearing 4 by the first through hole 12.
Please refer to Fig. 2 and Fig. 3, articulated elements further comprises a pair of transparent cover 6.Transparent cover 6 all offers fifth hole 60, and coupling shaft 5 further is arranged in the fifth hole 60.Thereby transparent cover 6 is fixed to the both sides of the second support arm 31 with removably respectively, and bearing 4 is relative fixing with the second support arm 31.After transparent cover 6 is fixed to the second support arm 31, the central lines of the center line of fifth hole 60 and fourth hole 40.Wherein, the diameter of the first through hole 12 is greater than the external diameter of transparent cover 6.Therefore, when taking off coupling shaft 5 and axle sleeve 2, can see through 12 dismountings of the first through hole or transparent cover 6 is installed, and then can dismantle or install bearing 4.
A pair of transparent cover 6 is fixed on the second support arm 31 by screw 61, thereby bearing 4 is gripped.The installation direction of screw 61 is parallel to the axial of coupling shaft 5, so conveniently passes 12 dismountings of the first through hole or mounting screw 61 and the purpose of realization dismounting or installation transparent cover 6.In order to prevent mutually internal free bearing 3 plaies of bearing 4, transparent cover 6 is fixing with bearing 4 and transparent cover 6 by screw (indicating).Further, in order to prevent bearing 4 relative coupling shaft 5 plaies, articulated elements can also further arrange at the internal diameter of bearing 4 and the setting sleeve (not shown) between the coupling shaft 5.
In order to prevent that dust from entering bearing 4, articulated elements further comprises a pair of seal ring 7 between bearing 4 and transparent cover 6.Seal ring 7 all offers the 6th through hole 70, after seal ring 7 is assembled between bearing 4 and the transparent cover 6, and the central lines of the center line of the 6th through hole 70 and fourth hole 40.Coupling shaft 5 further is arranged in the 6th through hole 70.Therefore the diameter of the first through hole 12, can see through 12 dismountings of the first through hole or transparent cover 6 is installed, and then can dismantle or install seal ring 7 greater than the external diameter of seal ring when taking off coupling shaft 5 and axle sleeve 2.
In the present embodiment, the 6th through hole 70 equal diameters of the second through hole 20 of axle sleeve 2, the fourth hole 40 of bearing 4 and seal ring 7 make the coupling shaft 5 that wore the second through hole 20, fourth hole 40 and the 6th through hole 70 obtain more stable support.In concrete the application, because the purpose of seal ring 7 is in order to prevent that dust from entering bearing 4, the diameter of the 6th through hole 70 of Sealing 7 can not limited, that is, the diameter of the 6th through hole 70 can be slightly larger than the diameter setting of fourth hole 40; When seal ring 7 was the rubber elastomeric material, the diameter of the 6th through hole 70 can also be less than the diameter setting of fourth hole 40; As long as can wearing, assurance coupling shaft 5 enters fourth hole 40.
In the practical application, the diameter of the diameter of the second through hole 20 and fourth hole 40 also can be unequal.For example, when coupling shaft 5 adopts 3 stops multidiameter shaft (not shown), comprise successively second portion (not shown) that first portion (not shown), the diameter of diameter maximum is placed in the middle and the third part (not shown) of diameter minimum, then the second through hole 20 diameters of two axle sleeves 2 respectively with the equal diameters of first portion and third part, the diameter of the fourth hole 40 of bearing 4 and the equal diameters of second portion.
Articulated elements further comprises a pair of end cap 8.A pair of end cap 8 lays respectively at the outside of a pair of the first support arm 11, and with the relative fixed connection shaft 5 of removably and axle sleeve 6.Further, end cap 8 is fixed on axle sleeve 2 and the coupling shaft 5 by the screw 80 along the axial installation of coupling shaft 5, and axle sleeve is clamped and fastened on the first support arm 11.
Be different from prior art, the setting of the utility model articulated elements is connected to the axle sleeve of outer free bearing, and by taking off axle sleeve and coupling shaft, bearing is dismantled or installed to first through hole that can see through outer free bearing, conveniently articulated elements safeguarded.
Except previous embodiment, the utility model articulated elements can also be done following change: the first through hole 12 of outer free bearing 1 can be non-circular through hole, the form fit of the shape of axle sleeve 2 and the first through hole 12; Axle sleeve 2 is arranged at can prevent mutually externally free bearing 1 rotation of axle sleeve 2 in non-circular the first through hole 12.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
