Abstract
The utility model discloses a large-size gear or belt pulley connecting structure which comprises a taper sleeve, wherein a large-size gear or belt pulley is provided with a taper hole with the same degree of taper as the taper sleeve; one side of the taper sleeve is provided with an axially-opened through groove; the external diameter of the top of the taper sleeve is greater than the internal diameter of the top of the taper hole; a fixing bolt is connected between a fixing hole and a threaded hole; the bottom of the large-size gear or belt pulley is fixed with a supporting plate; and the supporting plate is provided with a tightening bolt connected with the taper sleeve. The utility model is convenient for disassembly and assembly and simple for processing, has the advantage of firm connection, and can not damage the drive shaft after repeated disassembly and assembly.
Description
Technical field
The utility model relates to a kind of linkage structure, and is specifically a kind of be used to being installed in large gear on the transmission shaft or the linkage structure of belt pulley, belongs to the machinery field.
Background technique
Daily seen large gear or belt pulley normally are mounted on the transmission shaft with key, adopt interference fit between belt wheel and the transmission shaft.But the mode of this interference fit is in belt wheel installation or all comparatively difficult when dismantling, and therefore brings inconvenience to maintenance.If being dismounted for multiple times, the transmission shaft that is very easy to cooperate with it damages, and causes the damage of equipment.Name is called " a kind of belt pulley " application number and discloses a kind of belt pulley for the Chinese utility model patent of " CN201020163881.6 ", be installed on the transmission shaft, the center hole of belt pulley is cone shape hole, the identical adapter sleeve of tapering is housed in cone shape hole, have the endoporus that becomes Spielpassung with described transmission shaft in the adapter sleeve, one side of adapter sleeve has axially open, and this axially open runs through whole adapter sleeve, and belt pulley and adapter sleeve are fixed together by at least two tight fixed bolts.But this is easy accessibility as a result, and still, because just at one end fixing, therefore fixing and insecure, the adapter sleeve of the other end is using an end to occur easily distortion after the time.
The model utility content
In order to address the above problem, the utility model has designed a kind of large gear or belt wheel connection structure, and not only easy accessibility is processed simply, and is connected firmly, and being dismounted for multiple times can not damage transmission shaft.
The technical solution of the utility model is:
A kind of large gear or belt wheel connection structure, comprise tapered sleeve, described large gear or belt pulley are provided with the cone shape hole identical with described tapered sleeve tapering, described tapered sleeve is with circular hole, described tapered sleeve one side is provided with the groove of axially open, described tapered sleeve top external diameter is greater than described cone shape hole top internal diameter, described tapered sleeve top stretches out and is fixed disc, described fixed disc is provided with at least two fixed holes, described large gear or belt pulley be provided with described fixed hole with respect to tapped hole, be connected with fixing bolt between described fixed hole and the tapped hole, thereby the top of tapered sleeve is fixed on large gear or the belt pulley;
The bottom of described large gear or belt pulley is fixed with dunnage, and described dunnage is provided with the turnbuckle that is connected with described tapered sleeve; Thereby the bottom that makes tapered sleeve is fixed on large gear or the belt pulley.
Further, described dunnage and described large gear or belt pulley are structure as a whole.
Further, be equipped with the dismounting tapped hole on described dunnage and the fixed disc.
During use, first tapered sleeve is enclosed within on the transmission shaft of required connection, then large gear or belt pulley are enclosed within on the tapered sleeve, and by the turnbuckle on the dunnage and the fixing bolt on the fixed disc tapered sleeve is strained and fixed, because tapered sleeve is provided with the opening groove, therefore when tightening turnbuckle, tapered sleeve will shrink under the effect of cone shape hole, and is clamped in tightly on the axle that is connected.In the time will disassembling from axle, only need to take off from axle at the dismounting tapped hole bolt of screwing on.
The utility model has the advantage of: not only easy installation and removal, processing and fabricating is simple, and is connected firmly, and being dismounted for multiple times can not damage transmission shaft.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation;
Among the figure: 1-tapered sleeve, 2-fixed disc, 3-fixing bolt, 4-dunnage, 5-turnbuckle, 6-large gear or belt pulley.
Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of large gear or belt wheel connection structure, comprise tapered sleeve 1, described large gear or belt pulley 6 are provided with the cone shape hole identical with described tapered sleeve 1 tapering, described tapered sleeve 1 is with circular hole, the groove that described tapered sleeve 1 one sides are provided with axially open runs through whole tapered sleeve, described tapered sleeve 1 top external diameter is greater than cone shape hole top (the being big opening end) internal diameter of described large gear or belt pulley 6, described tapered sleeve 1 top (being big opening end) stretches out and is fixed disc 2, described fixed disc 2 is provided with and evenly is provided with three fixed holes, described large gear or belt pulley 6 be provided with described fixed hole with respect to tapped hole, be connected with fixing bolt 3 between described fixed hole and the tapped hole, thereby the top of tapered sleeve is fixed on large gear or the belt pulley; The bottom of described large gear or belt pulley (being the osculum end) is fixed with dunnage 4, and described dunnage 4 is provided with the turnbuckle 5 that is connected with described tapered sleeve; Thereby the bottom that makes tapered sleeve is fixed on large gear or the belt pulley.Described dunnage and described large gear or belt pulley are structure as a whole.
In addition, be equipped with the dismounting tapped hole on described dunnage and the fixed disc.
The tapering of cone shape hole is preferably 15 °-25 ° between 5 °-45 °.The width of the opening groove of tight cover is 4mm, large 2 millimeters than cone shape hole top internal diameter of tapered sleeve top external diameters.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technological scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
