Abstract
Provided is a novel spring reversely-buckled type structure for increasing resistance of belts. The novel spring reversely-buckled type structure for increasing the resistance of the belts comprises a fixed plate, a pulley bearing, a movable plate, a torsion spring and a rotating shaft. The novel spring reversely-buckled type structure for increasing the resistance of the belts is characterized in that one end of the rotating shaft is fixed on the fixed plate, the other end of the rotating shaft is connected with the movable plate, the torsion spring is sleeved in the middle of the rotating shaft, one end of the torsion spring is connected with the movable plate, the other end of the torsion spring is connected with the fixed plate, and the fixed plate is provided with the pulley bearing. The novel spring reversely-buckled type structure for increasing the resistance of the belts is mainly used on a belt wheel transmission mechanism and serves as a wheel pressing mechanism for adjusting tightness of the belts so that the belt wheel transmission mechanism can not step out due to the fact that the belts are excessively tight or loose.
Description
Technical field
The utility model relates to the belt wheel driving mechanism, and particularly a kind of spring left-hand thread formula belt adds the resistance new structure.
Background technique
The belt pulley transmission has the following advantages: can relax load impacting, operate steadily, low noise, low vibration, and simple in structure, easy to adjust, strict and have the function of overload protection unlike engagement driving for the manufacturing of belt pulley and installation precision, diaxon centre distance regulation range is big; These advantages allow pulley transmission mechanism be widely used in the mechanical transmission.
Yet, installation for pulley transmission mechanism, but relatively more difficult aspect adjusting, traditional regulative mode is the tense-lax of regulating belt by the position of regulating motor, be difficult to grasp and regulate belt to being fit to, tight not loose state, and since the life-span of belt shorter, thereby the elasticity that has influence on belt with being elongated and deformed easily after for a long time influences the action of driving mechanism.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of spring left-hand thread formula belt to add the resistance new structure, remedies belt pressure automatically, regulates the belt elasticity conveniently.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of spring left-hand thread formula belt adds the resistance new structure, comprise fixed plate, pulley bearings, mobile plate, torsion spring and rotating shaft, wherein: described rotating shaft one end is fixed on the fixed plate, the other end is connected with mobile plate, the centre is with torsion spring, described torsion spring one end is connected with mobile plate, and the other end is connected with fixed plate, on the described fixed plate pulley bearings is housed.
As further improvement of the utility model: described fixed plate is provided with several first torsion spring pore size distributions around rotating shaft.
As further improvement of the utility model: the bearing shaft that described mobile plate comprises base plate and is located at base plate one end, wherein said base plate are provided with second torsion spring hole and the rotary shaft hole, and a bearing cap is fixed on described bearing shaft top.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, to regulate the belt elasticity convenient, the belt distortion hour can be regulated belt pressure automatically, guarantees that the driving mechanism action is normal, has solved the problem of belt wheel drawstring or step-out.
Description of drawings
Fig. 1 is the utility model structural drawing and use state;
Fig. 2 is the mobile plate structural drawing.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to figs. 1 through 2, a kind of spring left-hand thread formula belt adds the resistance new structure, comprise fixed plate 1, pulley bearings 2, mobile plate 3, torsion spring 4 and rotating shaft 6, wherein: described rotating shaft 6 one ends are fixed on the fixed plate 1 by the degree fit system, the other end is connected with mobile plate 3 by gap fiting mode, mobile plate 3 can freely be rotated, the centre is with torsion spring 4, torsion spring 4 can be changed when regulating as required, described torsion spring 4 one ends are connected with mobile plate 3, the other end is connected with fixed plate 1, on the described fixed plate 1 pulley bearings 2 is housed.
Described fixed plate 1 is provided with several first torsion spring holes 5 and is distributed in around the rotating shaft 6, and the center, hole is all dropped on the same circumference, and this circumference and rotating shaft 6 all hearts, and the needs that radius of a circle is installed according to torsion spring 4 are processed.
The bearing shaft 30 that described mobile plate 3 comprises base plate 31 and is located at base plate 31 1 ends, wherein said base plate 31 is provided with the second torsion spring hole 32 and rotary shaft hole 33, a bearing cap 8 is fixed on described bearing shaft 30 tops, and wherein the slightly larger in diameter of rotary shaft hole 33 is in rotating shaft 6 diameters.
Use principle: during installation, torsion spring 4 can produce distortion, utilize the restoring force of torsion spring 4 that mobile plate 3 is rotated in rotating shaft 6, at this moment the pulley bearings on the mobile plate 32 can be to 7 one pressure of belt, belt 7 is inwardly compressed, thereby play the effect of regulating belt 7 elasticities, when belt 7 has than small deformation, because the effect of torsion spring 4, thereby pulley bearings 2 can guarantee the pulley transmission mechanism regular event to 7 one lasting pressure of belt, if can regulate the end that torsion spring 4 is fixed on fixed plate 1 when distortion pressure big or that need is big, allow torsion spring 4 be fixed on the first different torsion spring holes 5, thereby very fast adjusting pressure reaches the adjusting requirement, avoids tension and causes drawstring or cross pine and the step-out phenomenon that causes.
In sum, after those of ordinary skill in the art reads the utility model file, according to
The technical solution of the utility model and technical conceive need not creative mental labour and make other various corresponding conversion scheme, all belong to the scope that the utility model is protected.
