Detailed description of the invention
The exemplary embodiments embodying the utility model feature & benefits will describe in detail in the following description.Be understood that the utility model can have various changes in different embodiments, it neither departs from scope of the present utility model, and explanation wherein and to be shown in be the use explained in essence, and be not used to limit the utility model.
Embodiment 1
The utility model proposes a kind of pulley extractor 1, it is mainly used in dismantling impeller 2.Such as, the impeller 2 of dismounting centrifugal blower is extracted by its rotating shaft 3.Wherein the middle position of this impeller 2 offers axis hole, and impeller 2 offers multiple handling hole 22 around axis hole, and the rotating shaft 3 that impeller 2 is rotated is placed in axis hole.As depicted in figs. 1 and 2, an embodiment of the utility model pulley extractor 1.In present embodiment 1, this pulley extractor 1 comprises stressed plate 11, leading screw 12 and multiple set bolt 13.
As depicted in figs. 1 and 2, in present embodiment 1, stressed plate 11 is passed in order to stretch into the axis hole of impeller 2 and to be resisted against rotating shaft 3 in an end of leading screw 12, and leading screw 12 and stressed plate 11 threaded.
As depicted in figs. 1 and 2, in present embodiment 1, the quantity of set bolt 13 is two, and two set bolts 13 are oppositely arranged.Each set bolt 13 passes stressed plate 11 in order to be bolted in the handling hole 22 of impeller 2, and set bolt 13 is fixed on stressed plate 11 by the securing member such as but not limited to nut 131.
As depicted in figs. 1 and 2, in present embodiment 1, stressed plate 11 is rounded, so that force when dismantling impeller 2 is convenient, but not as limit.Stressed plate 11 offers a centre bore two regulating tanks 111.Centre bore is opened in the center of stressed plate 11 and hole wall offers screw thread, is bolted through with for leading screw 12.Two regulating tanks 111 are respectively by the center outwards relatively scatter distributions of stressed plate 11, and non-through between two regulating tanks 111 and centre bore, and two regulating tanks 111 are in order to pass for two set bolts 13 respectively.And two set bolts 13 pass stressed plate 11 by regulating tank 111 respectively, and the handling hole 22 of impeller 2 is fixed in an end of each set bolt 13, and stressed plate 11 is fixed on by a nut 131 in the other end.By set bolt 13, stressed plate 11 and impeller 2 are fixed, recycling leading screw 12 and the threaded relation of stressed plate 11 utilize the principle of leading screw 12, leading screw 12 is converted to stressed plate 11 relative to the axial rotation motion of stressed plate 11 move upward relative to the straight line of leading screw 12, because leading screw 12 is resisted against rotating shaft 3, therefore achieve impeller 2 to move upward relative to the straight line of rotating shaft 3, realize impeller 2 further and extracted by rotating shaft 3.
In addition, in order to ensure structural strength when leading screw 12 and impeller 2 relatively rotate, in present embodiment 1, bar footpath is selected to be greater than the leading screw 12 in set bolt 13 bar footpath.Further, when selecting the securing member of nut 131 as set bolt 13, external diameter should be selected to be greater than the nut 131 of regulating tank 111 groove width, to realize fastening bit function to set bolt 13.
But, in other embodiments, in order to strengthen the fixation of set bolt 13 pairs of stressed plates 11 and impeller 2, make set bolt 13 can not produce wobble effects fixed effect, then need regulating tank 111 to be designed to the structure that groove width equals the bar footpath of set bolt 13, not as limit.
It should be noted that, because stressed plate 11 is fixedly connected with impeller 2 through regulating tank 111 by two set bolts 13, therefore, when this pulley extractor 1 is applied to the impeller 2 of different size, only need unclamp nut 131, and two set bolts 13 are carried out position adjustments along regulating tank 111, to correspond to the position of the handling hole 22 of impeller 2, further expand the scope of application of pulley extractor 1.
Embodiment 2
Another embodiment of the utility model pulley extractor 1, it is roughly the same with embodiment 1, and difference is: as shown in Figure 3, in present embodiment 2, utilizes the hole be opened on stressed plate 11 to replace regulating tank 111.Specifically, the middle position of stressed plate 11 offers the threaded centre bore of tool, with for leading screw 12 through and with its threaded.In addition, the circumferential position of stressed plate 11 offers multiple through hole 112, in order to pass for multiple set bolt 13 respectively.
It should be noted that, as shown in Figure 3, the mode of offering of multiple through hole 112 should correspond to the concrete distributing position of the handling hole 22 of impeller 2.Further, in order to the impeller 2 making this pulley extractor 1 go for plurality of specifications, the multiple through holes 112 therefore stressed plate 11 offered can be incomplete same with the distance of centre bore.Specifically, these through holes 112 install it can be divided into many groups with the distance of centre bore respectively, each through hole 112 of mutually same group is located at one with the middle position of stressed plate 11 (i.e. the center of circle of centre bore) on the circular path in the center of circle, and through hole 112 quantity often organized is at least two.Preferably, in multiple through holes 112 of mutually same group, wherein at least two for being oppositely arranged, namely this two through holes 112 and centre bore are positioned on straight line, not as limit.
Though exemplary embodiment describe pulley extractor of the present utility model with reference to several, should be understood that term used be illustrate and illustrative, and not restrictive.Specifically can implement in a variety of forms due to the utility model and not depart from its design or essence, therefore, above-described embodiment is not limited to any aforesaid details, and explain widely in the design that should limit in claim of enclosing and scope, therefore the whole change fallen in claim or its equivalent scope and remodeling all should be claim of enclosing and contained.
