Abstract
The utility model relates to machinery industry, in particular to wheel component wheel hub device, which comprises a wheel flange (1) and a wheel hub (2), wherein the inner hole of the wheel hub (2)is a cylindrical surface and the outer circle is a conical surface, a flange is arranged on the end of big diameter of the conical surface, an opening is arranged axially, the inner hole of the wheel flange (1) matches the outer circle of the wheel hub (2) and is fixed on the outer circle of the wheel hub (2). When the utility model is used in tight fit condition, complicated press-mounting tools are not required for installation, the heating and hammering process is not required. Only normal tools are needed to tighten a screw fastener (3) for meeting the fit requirements. Positioning can be set on any spots of a fitted shaft so as to make alignment become easy; contrarily, special tools for dismantling are not needed in disassembling process, the screw fastener (3) can only be loosened and the wheel flange (1) can only be tapped. The utility model has the advantages of simple structure, easy fabrication, easy disassembly and maintenance, which is mainly used for the large and middle sized components with tight fit, assembly and disassembly, positioning process and alignment.
Description
Affiliated technical field:
The utility model relates to mechanical industry, refers more particularly to the structure of some wheel-class parts hub unit.
Background technique:
At present, wheel class formation part is widely used on the rotating equipment of all trades and professions as flywheel, belt pulley, gear etc.When these cylindrical hole parts cooperated with axle, axially locating commonly used and fixation method had following several: A: the shaft shoulder, axle collar location;
B: sleeve location;
C: axle head baffle plate, shaft end ring location;
D: circlip location;
E: Cock screw; Folk art term circle attachment screw location.
More than several localization methods when being applied to miniature parts, simplicity of design, easy to manufacture, easy accessibility; And be applied to large and medium-sized part and cooperate when tight, work such as dismounting, location, centering are then very difficult, keep in repair also very inconvenient.
The model utility content:
The utility model purpose provides a kind of multiple spot pretension, formula hub unit easy to assemble, solves the problems referred to above that exist in the background technique.
The technical solution of the utility model is: multiple spot pretension, formula hub unit easy to assemble are made up of wheel rim 1, wheel hub 2, wheel hub 2 endoporus are the cylndrical surface, cylindrical is the conical surface, conical surface larger diameter end is provided with flange, open and clear vertically mouthful, the cylindrical of the endoporus of wheel rim 1 and wheel hub 2 is complementary, and is buckled on the cylindrical of wheel hub 2 and is fastenedly connected by screw 3, and screw 3 is provided with check washer 4.
Adopt the utility model, when being applied to drive fit, installation does not need complicated press mounting tool, need not heating, need not beat, and need only tighten fastening screw trip bolt by general tool, can reach the cooperation requirement; Can be on fitted shaft location positioning arbitrarily, be convenient to centering.Otherwise during dismounting, do not need removal tool special, need only become flexible fastening screw trip bolt, the tip-tap wheel rim just can be pulled down.
The utlity model has simple in structure, easy to manufacture, dismounting, easy to maintenance, when being mainly used in large and medium-sized part and cooperating tightly, the characteristics of dismounting, location, centering.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model sectional view.
Among the figure: wheel rim 1, wheel hub 2, screw 3, check washer 4.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.In an embodiment, wheel hub 2 endoporus are the cylndrical surface, cylindrical is the conical surface, conical surface larger diameter end is provided with flange, open and clear vertically mouthful, circumferential contractile taper sheath, the cylindrical of the endoporus of wheel rim 1 and wheel hub 2 is complementary, and be buckled on the cylindrical of wheel hub 2 and be fastenedly connected by screw 3, screw 3 is provided with check washer 4, the part that utilizes this structure to make, when being applied to drive fit, installation does not need complicated press mounting tool, need not heating, need not beat, and need only tighten fastening screw trip bolt 3 by general tool, can reach the cooperation requirement; Can be on fitted shaft location positioning arbitrarily, be convenient to centering.Otherwise when dismounting do not need removal tool special, need only become flexible fastening screw trip bolt 3, and tip-tap wheel rim 1 just can be pulled down, the saving of labor, save time, laborsaving, province's expense.
