Embodiment
The utility model describe laterally, longitudinally, inner side, outside, and upper and lower, be according to the putting position of this accompanying drawing middle belt pulley structure, therefore do not limit scope of the present utility model.
Refer to Fig. 1～2, the belt sheave structure the utility model proposes, comprises radiating wheel 100 and drive wheel 200.
Particularly, radiating wheel 100 comprises integrated dish axle 110 and disk body 120.Its mid-game axle 110 is arranged on the central position of disk body 120, in disk body 120 back side projections.Disk body 120 presents regular polygon shape, and every one side is the circular arc of indent.
In the middle of drive wheel 200, have through hole 210, and be inserted on dish axle 110 by through hole 210, realize the socket with radiating wheel 100.The screw mounting hole that all has coupling on drive wheel 200 and dish axle 110, is inserted in after dish axle 110, can fix by screw.
The belt sheave structure the utility model proposes, integrated belt pulley is made into detachable radiating wheel 100 and drive wheel 200, two visual working condition requirements of workpiece are manufactured respectively, simplify the structure, convenient processing, reduced manufacturing mechanism requirement and cost, single replaceable part is convenient to maintenance simultaneously.
Referring to Fig. 3～4, in one embodiment, radiating wheel 100 and drive wheel 200 are fastened togather by double wedge 111 and groove 211.
Particularly, drive wheel 200 intermediate throughholes 210 are manhole, and inwall hoop is distributed with the groove 211 of certain depth.Matchingly, the dish axle 110 of radiating wheel 100 is cylindrical, and the outer wall of dish axle 110 is provided with double wedge 111.When drive wheel 200 is inserted in dish axle 110, double wedge 111 embeds groove 211.In belt pulley sense of rotation, radiating wheel 100 can not produce and relatively move with drive wheel 200 like this, prevents skidding.End is fixed by screw again, prevents drive wheel 200 radiating wheel 100 that longitudinally comes off.
Further, dish axle 110 is splined shaft, and groove 211 is spline joint with double wedge 111.
Particularly, double wedge 111 is evenly distributed on dish axle 110 outer side walls.Matchingly, groove 211 is evenly distributed on through hole 210 inwalls, and both form spline joint.
By spline joint, can under the good transmission effect of maintenance, reduce the quantity of required screw, avoid offering too much mounting hole at dish axle 110, with respect to relying on many screw fixation methods to increase the rigidity of dish axle.
In the present embodiment, groove 211 quantity are 3～6, are evenly distributed on through hole 210, and the double wedge 111 of equal number is set on dish axle 110 accordingly.Preferably, choose groove and double wedge quantity and be 4.
Referring to Fig. 4, in one embodiment, drive wheel 200 comprises wheel body 220, the first plate washer 230 and second baffle 240.
Particularly, wheel body 220, for belt is installed, drives radiating wheel 100 to rotate together thereby belt rotates wheel body 220.The first plate washer 230 and second baffle 240 are separately positioned on the both sides of wheel body 220.When installation, the first baffle plate 230 is positioned at the inner side of drive wheel 200, and near radiating wheel one side, second baffle 240 is positioned at outside.Wherein the first baffle plate 230 is all large than wheel body 220 with the diameter of second baffle 240.
Arrange after baffle plate, at drive wheel 200, in when work, belt under baffle limiting effect only on the wheel body 220 in the middle of drive wheel 200, can not move toward both sides to such an extent as to comes off.The stability of guarantee work.
Further, in the present embodiment, after drive wheel 200 is socketed on radiating wheel 100, the first plate washer 230 of inner side and radiating wheel 100 surface laminatings.
The above-mentioned imporosity having increased after drive wheel 200 and radiating wheel 100 assemblings that arranges, has increased join strength, and can reduce the wearing and tearing of set screw.
Drive wheel 200 adopts casting aluminium material.In working procedure, because drive wheel 200 is directly connected with belt, in working procedure, need to bear larger torsion, in drive wheel 200 rigidity of employing casting aluminium material, more can reach requirement, can bear the unnecessary heat that belt friction produces simultaneously.
In one embodiment, referring to Fig. 5～6, on radiating wheel 100, be provided with blade 130.
Particularly, blade 130 is arranged on disk body 120 another sides with respect to dish axle 110.The vertical disk body 120 of blade 130 arranges, and starts to extend to edge outside projection from disk body 120 centers.Install after blade 130, in the time that disk body 120 rotates, band moving vane 130 rotates, and forms air cooling equipment, and the motor in blade 130 fronts is carried out to wind-cooling heat dissipating.
Further, the quantity of blade 130 is 6～9.
Blade 130 quantity can be to count setting according to the limit of polygonal disk body 120.Blade 130 was arranged to dredge and overstockedly all can be exerted an influence to radiating effect; Therefore blade 130 quantity are set as 6～9, are evenly distributed on disk body 120, and angle intervals is identical each other.Blade 130 quantity are preferably 8.
