Abstract
The utility model provides a ground roll which comprises a main shaft, wherein a first bearing and a second bearing are arranged at two ends of the main shaft; the first bearing and the second bearing are fixed through a first bearing pedestal and a second bearing pedestal; the bearing pedestals are sleeved with an outer covering body; a first hole stop and a second hole stop are also arranged at two ends of the outer covering body. The ground roll is simple in structure, high in abrasion resistance and light in mass.
Description
Technical field
The utility model relates to a kind of ground roll.
Background technique
In prior art, ground roll generally adopts cast iron ground roll, in actual job, owing to being that cast iron ground roll is that weight is large in carrying, is not easy carrying.
Model utility content
For above-mentioned defect and the problem of prior art, the utility model object has been to provide a kind of simple in structure, and wear-resisting property is good, the ground roll that quality is light.
In order to achieve the above object, the utility model provides following technological scheme:
A kind of ground roll, comprise main shaft, the two ends of main shaft are respectively equipped with clutch shaft bearing and the second bearing, clutch shaft bearing and the second bearing are fixed by clutch shaft bearing seat and the second bearing support respectively, also be provided with an outer inclusion covering on described clutch shaft bearing seat and the second bearing support, described outer inclusion is provided with the endoporus for holding described clutch shaft bearing seat and the second bearing support, and the two ends of described endoporus are established described clutch shaft bearing seat and the second bearing support are carried out to spacing the first hole gear and the second hole gear.
Further, on the outer surface of outer inclusion, be also provided with the recessed grain for holding wire rope.
Further, the degree of depth of groove is 12-15mm.
Further, outer inclusion and bearing support are nylon monomer-cast nylon body.
Further, the diameter of the first hole gear and the second hole gear is 125mm.
The beneficial effects of the utility model are, what adopt due to the outer inclusion of the utility model ground roll and bearing support is the nylon monomer-cast nylon that can improve abrasion resistance, makes overall ground roll weight saving 80%, has saved manufacture cost.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model ground roll.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the disclosed a kind of ground roll of the utility model, comprise main shaft 1, the two ends of main shaft 1 are equipped with clutch shaft bearing 21 and the second bearing 22, clutch shaft bearing 21 and the second axle 22 hold all fixing by clutch shaft bearing seat 31 and the second bearing support 32, wherein, on bearing support, cover has inclusion 4 outside, outer inclusion 4 is provided with endoporus 40, the two ends of endoporus 40 are also provided with the first hole gear 51 and the second hole gear 52, the diameter of the first hole gear 51 and the second hole gear 52 is 125mm, and the first hole gear 51 and the second hole gear 52 mainly play spacing effect.
Preferred technological scheme, is also provided with recessed grain on outer inclusion 4, and the degree of depth of groove is 12-15mm, when operation by wirerope-winding in groove of the present utility model.
Preferred technological scheme, outer inclusion 4 and bearing support are nylon monomer-cast nylon, adopt nylon monomer-cast nylon quality of the present utility model can be alleviated to 80%, and can improve abrasion resistance, reduce production costs.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
