By adopting technique scheme, at the combination roller shaft and sidewinder between wheels and be provided with limit stoper, can prevent sidewinder wheels can acting on combination and not spin in roller shaft because of axial force, cause and sidewinder wheels uneven wear, stuck, cause side wheel to damage, scratch gantry channel-steel body phenomenon.
The utility model further is set to: described limit stoper is: described sidewindering on wheels offers locating slot, and described combination roller shaft is provided with locating stud, in the locating slot on the inner inserting side roller group of locating stud.
By adopting technique scheme, at the combination roller shaft with sidewinder on wheels locating stud and locating slot are set respectively, can facilitate locating stud to enter locating slot, and enter locating slot fixing after, can not produce because of the impact of axial force loosening.
The utility model further is set to: the described wheels that sidewinder comprise side wheel, sidewinder wheel shaft and side roller brackets, and described side wheel is sheathed on and sidewinders on wheel shaft, and the described wheel shaft that sidewinders is arranged in side roller brackets, offers locating slot on described side roller brackets.
By adopting technique scheme, for preventing that sidewindering wheels spins and lay a good foundation in the combination roller shaft, on due to the combination roller shaft, offer locating stud, when mounted, only need be by the position of locating stud and the position alignment of locating slot, just can easily locating stud be inserted to locating slot, and the firm displacement of locating stud at locating slot.
The utility model further is set to: described vertical roller group comprises vertical roller shaft outer ring, bearing roller, vertical roller shaft inner ring and end ring, described bearing roller is between vertical roller shaft outer ring and vertical roller shaft inner ring, and described end ring gear is located at the both sides of vertical roller shaft outer ring and vertical roller shaft inner ring.
By adopting technique scheme, to indulge roller shaft outer ring and inner ring divides and is arranged, between arranges bearing roller, and be located at the both sides of indulging the roller shaft Internal and external cycle with the end ring gear, so both can prevent that bearing roller broke away from track in the process of sliding, can play better firm effect to the combination roller shaft again.
The utility model further is set to: a port of described combination roller shaft offers two draw-in grooves, and the inboard of described end ring is provided with annular protrusion, and described annular protrusion is sheathed on the draw-in groove of combination roller shaft.
By adopting technique scheme, can make the back-up ring clip on the combination roller shaft, can not rotate because of the rotation of vertical roller group, to such an extent as to the roller that runs out bearing brings unnecessary hidden danger to normal work.
For content of the present utility model is more likely to be clearly understood, below according to specific embodiment of the utility model also by reference to the accompanying drawings, the utility model is described in further detail.
The accompanying drawing explanation
Fig. 1 is a kind of fork truck composite rolling wheel structural representation of the utility model specific embodiment.
Fig. 2 is a kind of fork truck composite rolling wheel cross-sectional view of the utility model specific embodiment.
Embodiment
As shown in Figure 1-2, for the disclosed a kind of fork truck composite rolling wheel of the utility model, comprise vertical roller group, combination roller shaft 1 and sidewinder wheels, described vertical roller group is sheathed on the external cylindrical surface of combination roller shaft 1, combination roller shaft 1 is sheathed on the side roller brackets that sidewinders wheels, described combination roller shaft 1 and sidewinder between wheels and be provided with limit stoper.At combination roller shaft 1 and sidewinder between wheels and be provided with limit stoper, can prevent sidewinder wheels can acting on combination and not spin in roller shaft 1 because of axial force, cause and sidewinder wheels uneven wear, stuck, cause side wheel to damage, scratch gantry channel-steel body phenomenon.
Described limit stoper comprises locating slot 20 and locating stud 21, and described locating slot 20 is opened in and sidewinders on wheels, and described locating stud 21 is located on combination roller shaft 1.At combination roller shaft 1 with sidewinder on wheels locating stud 21 and locating slot 20 are set respectively, can facilitate locating stud 21 to enter locating slot 20, and enter locating slot 20 fixing after, can not produce because of the impact of axial force loosening.In the present embodiment, locating stud 21 can be located at and be sidewindered on wheels, locating slot 20 be opened in the combination roller shaft on 1, also can reach spacing effect.
