The taper sleeve with the perforation screw and taper fit connection structure, disclosed by the utility model, has the beneficial effects of being steady in mechanical transmission performance, simple in structure, easy to manufacture, simple and convenient to operate, time-saving and labor-saving.
Description
Technical field
The utility model relates to mechanical technology, and is particularly a kind of by junction of the edges of two sheets of paper screw and taper fit connecting structure tapered sleeve.
Background technique
In the common mechanical transmission, axle is to be fixed together by key with the wheel that is enclosed within on the axle, realizes the purpose of transmitting movement moment of torsion.The key ways of connecting is simple in structure, can wheel be fixedly linked in axle well and go up and together rotate with axle, but traditional mode also must set out keyway on the wheel hub of axle and wheel; Not only weakened the mechanical strength of axle and wheel hub; And can produce stress at the position that axle and wheel hub are offered keyway and concentrate, crackle, crack even opening appear easily at the keyway place of axle or wheel hub, can directly cause mechanical failure; Have a strong impact on the proper functioning life-span of machine, maintenance cost is high.In addition, the key Placement is also become flexible than being easier to occur connecting, and influences transmission accuracy; So need often to change key, but the key Placement exists the defective of dismounting inconvenience again, the installation or removal wheel mostly is that the mode that adopts manpower to beat bump is carried out; Waste time and energy troublesome poeration.
The model utility content
The purpose of the utility model is to overcome the shortcoming of existing technology, provides a kind of simple in structure, easy to manufacture, easy and simple to handle by junction of the edges of two sheets of paper screw and taper fit connecting structure tapered sleeve.
The purpose of the utility model realizes through following technological scheme: a kind of by junction of the edges of two sheets of paper screw and taper fit connecting structure tapered sleeve; It comprises tapered sleeve, and tapered sleeve is provided with the swelling seam, and tapered sleeve links to each other with wheel hub through junction of the edges of two sheets of paper screw; Transmission shaft passes tapered sleeve; And link together through key and tapered sleeve, wheel hub is provided with semicircle assembling screw and semicircle blind hole B, in the junction of the edges of two sheets of paper position that tapered sleeve and wheel hub are equipped with; Tapered sleeve is provided with one group of semicircle blind hole A that matches with semicircle assembling screw, and tapered sleeve is provided with one group of semicircle dismounting screw that matches with semicircle blind hole B.
The utlity model has following advantage: mechanical transmission performance is stable, and is simple in structure, easy to manufacture, easy and simple to handle, time saving and energy saving.
Description of drawings
Fig. 1 is the structural representation of the utility model
Fig. 2 is A-A view of Fig. 1.
Among the figure, 1-tapered sleeve, the conical press fit face of 2-, 3-semicircle assembling screw, 4-wheel hub, 5-junction of the edges of two sheets of paper screw, 6-key, 7-semicircle blind hole A, 8-transmission shaft, 9-swelling seam, 10-semicircle dismounting screw, 11-semicircle blind hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
As shown in Figure 1, a kind of by junction of the edges of two sheets of paper screw and taper fit connecting structure tapered sleeve, it comprises tapered sleeve 1; Tapered sleeve 1 is provided with swelling seam 9; Tapered sleeve 1 links to each other with wheel hub 4 through junction of the edges of two sheets of paper screw 5, and transmission shaft 8 passes tapered sleeve 1, and links together through key 6 and tapered sleeve 1; Wheel hub 4 is provided with semicircle assembling screw 3 and semicircle blind hole B11; In the junction of the edges of two sheets of paper position that tapered sleeve 1 and wheel hub 4 are equipped with, tapered sleeve 1 is provided with one group of semicircle blind hole A7 that matches with semicircle assembling screw 3, and tapered sleeve 1 is provided with one group of semicircle dismounting screw 10 that matches with semicircle blind hole B11.
The working procedure of the utility model is following: when wheel is installed, through key 6 tapered sleeve 1 is installed on the transmission shaft 8, wheel hub 4 is enclosed within on the tapered sleeve 1; Insert in the semicircle blind hole A7 with one group of junction of the edges of two sheets of paper screw 5, and be threaded, withstand the bottom continued rotation of semicircle blind hole A7 when junction of the edges of two sheets of paper screw 5 and tighten with semicircle assembling screw 3 formations; At this moment produce displacement vertically between tapered sleeve 1 and the wheel hub 4, tapered sleeve 1 swelling is gradually wedged in the taper hole of wheel hub 4, between wheel hub 4 and tapered sleeve 1, forms friction tight conical press fit face 2; Under pressure; 9 contraction deformations are stitched in swelling, and tapered sleeve 1 is tightly waled transmission shaft 8, and wheel hub 4 just is fixedly connected on the transmission shaft 8 firmly like this; During the dismounting wheel, one group of junction of the edges of two sheets of paper screw 5 is withdrawed from, screw in the semicircle dismounting screw 10 that matches with semicircle blind hole B11; After junction of the edges of two sheets of paper screw 5 props up semicircle blind hole B11 bottom, continue to screw, reverse displacement takes place with wheel hub 4 in tapered sleeve 1 beginning; Tapered sleeve 1 is withdrawed from wheel hub 4, can pull down wheel.
