Abstract
The utility model discloses a taper sleeve connecting structure formed by a screw matched with taper. The taper sleeve connecting structure formed by the screw matched with the taper comprises the taper sleeve (6) and a hub (9). The taper sleeve (6) is provided with a swelling tight seam (5). The hub (9) is provided with a taper hole, and the taper sleeve (6) is plugged into the taper hole to form an extrusion fitting face (7) with the hub (9). The end face (10) of the hub (9) is provided with a group of assembly screw holes (8). One end of the taper sleeve (6), which is not plugged into the hub (9), is made into a circle of bulge loop plate (1) which is provided with an assembly through hole (11) and a dismantling screw hole (12). The taper sleeve (6) and the hub (9) are fixed together through a screw (2). A transmission shaft (4) is fixed together with the taper sleeve (6) through a key (3) after passing through the taper sleeve (6) and the hub (9). The taper sleeve connecting structure formed by the screw matched with the taper has the advantages of being stable in mechanical transmission performance, simple in structure, easy to manufacture, convenient to operate, and time saving and labor saving in installation and dismantling.
Description
Technical field
The utility model relates to mechanical engineering technical field, and is particularly a kind of by screw and taper fit tapered sleeve connecting structure.
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 constant defective of dismounting 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 use by screw and taper fit tapered sleeve connecting structure.
The purpose of the utility model realizes through following technological scheme: a kind of it comprises tapered sleeve and wheel hub by screw and taper fit tapered sleeve connecting structure, and tapered sleeve is provided with the swelling seam; Wheel hub is provided with taper hole, and the tapered sleeve plug forms the press fit face with wheel hub in taper hole; The end face of wheel hub is provided with an assembling and joins screw; Tapered sleeve is not filled in an end of wheel hub and is made a circle bulge loop plate, and the bulge loop plate is provided with assembling through hole and dismounting screw, and tapered sleeve is in the same place through screw with wheel hub; Transmission shaft passes tapered sleeve and wheel hub, and is fixed together through key and tapered sleeve.
The utlity model has following advantage: mechanical transmission performance is stable, and simple in structure, easy to manufacture, easy and simple to handle, installing/dismounting is time saving and energy saving.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further description:
As shown in Figure 1, a kind of by screw and taper fit tapered sleeve connecting structure, it comprises tapered sleeve 6 and wheel hub 9; Tapered sleeve 6 is provided with swelling seam 5, and wheel hub 9 is provided with taper hole, and tapered sleeve 6 plugs are in taper hole; Form press fit face 7 with wheel hub 9, the end face 10 of wheel hub 9 is provided with an assembling and joins screw 8, and tapered sleeve 6 is not filled in an end of wheel hub 9 and made a circle bulge loop plate 1; Bulge loop plate 1 is provided with assembling through hole 11 and dismounting screw 12; Tapered sleeve 6 is fixed together through screw 2 with wheel hub 9, and transmission shaft 4 passes tapered sleeve 6 and wheel hub 9, and is fixed together through key 3 and tapered sleeve 6.
The working procedure of the utility model is following: when wheel is installed, with key 3 tapered sleeve 6 is installed on the transmission shaft 4, wheel hub 9 is enclosed within on the tapered sleeve 6; Wheel hub 9 forms press fit face 7 with tapered sleeve 6, and screw 2 is passed assembling through hole 11 and precession assembling screw 8, the screw 2 of screwing; 5 pressurized contraction deformations are stitched in swelling, and tapered sleeve 6 shrinks banding transmission shaft 4, advances in the taper hole of tapered sleeve 6 on wheel hub 9 simultaneously; With wheel hub 7 swellings, like this transmission shaft 4 just and wheel hub 9 be fixed together.During the dismounting wheel, screw 2 is screwed out assembling screw 8 and assembling through hole 11, then screw 2 is screwed in dismounting screw 12; After screw 2 withstands end face 10, continue to screw, tapered sleeve 6 just can withdraw from the taper hole on the wheel hub 9; No longer and swelling between the wheel hub 9, meanwhile, 5 expansions of swelling seam; Tapered sleeve 6 unclamps transmission shaft 4, so just can wheel have been removed from transmission shaft 4.
