Referring to Fig. 1, prior art comprises rolling bearing 1, frame 2, plane bearing 3, end cap 4, central shaft 5, rolls wheel 6, slide block 7 and slide block axle 8, wherein, has annular center axial trough 51 on the nearly outboard end of central shaft 5.
In this prior art, central shaft 5 is arranged in frame 2, between the medial extremity of central shaft 5 and frame 2, is provided with rolling bearing 1; The outboard end of central shaft 5 passes outside frame 2, is stamped end cap 4 on the opening of frame 2, and central shaft 5, through end cap 4, is provided with plane bearing 3 between central shaft 5 and end cap 4, and plane bearing 3 and end cap 4 make the central shaft 5 can not relative frame 2 axially-movables; Slide block axle 8 successively through a side of slide block 7, roll the opposite side of wheel 6 and slide block 7, roll wheel 6 and be arranged on slide block 7 by slide block axle 8, roll wheel 6 slide block 7 axially-movables relatively; Rolling coupling in the center axial trough 51 of taking turns one end outer rim projection of 6 and snapping in central shaft 5 coincide.
Utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design, the channelling machine central shaft that easy for installation, cost is low and the work structuring of rolling wheel are provided.
The technical scheme in the invention for solving the above technical problem is: this channelling machine central shaft comprises frame, central shaft with the work structuring of rolling wheel, rolls wheel and slide block, described central shaft is arranged in frame, the described wheel that rolls is arranged on slide block, and the described wheel that rolls is connected with central shaft coupling; It is characterized in that: also comprise guide ring and cannelure, described guide ring is enclosed within outside central shaft, and both interference fit; Described rolling on wheel has cannelure, and the periphery of described guide ring snaps in this cannelure.Plane bearing and end cap have been removed, improve central shaft and rolled wheel, added guide ring, interference fit is enclosed within guide ring outside central shaft and is stuck in all the time in the cannelure rolling on wheel and does not depart from, utilize guide ring to carry out axial location to central shaft, guaranteed that central shaft is constant all the time with the relative position that rolls wheel; When mounted, although roll still slide block axially-movable relatively of wheel, central shaft is frame axially-movable relatively, rolls wheel and central shaft simultaneously and mates all the time connection, and whole machine installation is more convenient, and has reduced auxiliary component.
Between central shaft described in the utility model and frame, be provided with rolling bearing.Central shaft can steadily rotate glibly in frame.
The wheel that rolls described in the utility model is arranged on slide block by slide block axle.Rolling wheel can rotate relative to slide block around slide block axle.
The preferred described rolling bearing of the utility model is arranged between the medial extremity and frame of central shaft.
On central shaft described in the utility model, have annular center axial trough, described in roll one end outer rim projection of wheel and snap in this center axial trough.Roll one end outer rim projection of wheel and snap in the axial trough of central shaft Shang center, making to roll wheel and be connected with central shaft coupling.
The utility model compared with prior art, have the following advantages and effect: utilize the guide ring to carry out axial location to central shaft, guaranteed central shaft and rolled the relative position of wheel constant all the time, the required precision of easy for installation and satisfied assembling, reduce auxiliary component simultaneously, saved cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation of the utility model embodiment.
In figure: rolling bearing 1, frame 2, plane bearing 3, end cap 4, central shaft 5, roll wheel 6, slide block 7, slide block axle 8, guide ring 9, center axial trough 51, cannelure 61.
The specific embodiment
Below in conjunction with accompanying drawing and by embodiment, the utility model is described in further detail, and following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment.
Referring to Fig. 2, the present embodiment comprises rolling bearing 1, frame 2, central shaft 5, rolls wheel 6, slide block 7, slide block axle 8 and guide ring 9, wherein, rolls on wheel 6 and has cannelure 61, has annular center axial trough 51 on the nearly outboard end of central shaft 5.
In the present embodiment, central shaft 5 is arranged in frame 2, between the medial extremity of central shaft 5 and frame 2, is provided with rolling bearing 1; Slide block axle 8 successively through a side of slide block 7, roll the opposite side of wheel 6 and slide block 7, roll wheel 6 and be arranged on slide block 7 by slide block axle 8; Rolling coupling in the center axial trough 51 of taking turns one end outer rim projection of 6 and snapping in central shaft 5 coincide.
