The specific embodiment
Below in conjunction with accompanying drawing to the utility model provide a kind of for the endless-track vehicle driving wheel fixedly the dismounting utensil of plug screw be further described.
As shown in Figure 1, gear ring 1 inside is provided with a circular trough and two ring gears, location-plate 2 is put into circular trough, has a circular groove in the location-plate 2 simultaneously, after location-plate 2 is put into gear ring 1, holding screw 9 screw-ins are distributed in gear ring 1 screwed hole all around, and holding screw 9 inserts in the groove of location-plates 2 subsequently, finishes the longitudinal register of location-plate 2.Connecting cylinder 6 fixedlys connected by modes such as welding with location-plate 2, positioning chuck 3 inserts and connects on the cylinder 6, it is corresponding circular aerial that copper sheathing 8 is pressed into positioning chuck 3, locating piece 4 is connected with positioning chuck 3 by the draw-in groove mode, and utilize securing members 5 such as nut fastening, gear 7 inserts positioning chuck 3 tops by copper sheathing 8, and meshes by the gear of the ring gear in the gear ring and gear ring 1.
As shown in Figure 2, gear 7 axle heads are the square slot, and this square groove matches with the cubic plush copper of standard torque spanner.As shown in Figure 3, the ring gear of gear ring 1 lower end matches with driving wheel plug screw external gear size, the shape of locating piece 4 one ends matches with driving wheel wheel hub groove, be rectangular boss, be connected with positioning chuck 3 corresponding rectangular channels, the other end is thread cylinder, and locating piece 4 matches with positioning chuck 3 by the rectangle draw-in groove on the positioning chuck 3 like this, is undertaken fastening with securing member 5 by the screw on the locating groove subsequently.
Specifically using of the utensil that the utility model provides is as follows, as shown in Figure 4, the ring gear of gear ring 1 small end is meshed with driving wheel plug screw external tooth, the boss of locating piece 4 inserts in the driving wheel wheel hub groove 10, the number of locating piece 4 can three and more than, the location of so just having finished driving wheel bolt disassembly specific purpose tool.The cubic boss that becomes torque wrench is inserted in the cubic groove of gear 7, on lift the change torque wrench, gear 7 places form anticlockwise moment of torsion, this moment of torsion passes to the driving wheel plug screw by bull gear, when moment of torsion reaches certain value, plug screw is loosening, finishes the fixedly dismounting of plug screw of driving wheel; Otherwise, pressing down the change torque wrench, plug screw place row becomes clockwise moment of torsion, and plug screw can be fastened, and the power that becomes torque wrench reaches when setting value, and the product of this value and gearratio is screw-down torque, considers coefficient of friction, can obtain the scope of screw-down torque.When the gearratio of bull gear and pinion during in certain numerical value, the driving wheel plug screw can rely on the minority manpower to finish dismounting.
Should be noted that at last: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although with reference to above-described embodiment the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of this claim scope.
