Abstract
The utility model belongs to the technical field of power transmission equipment, concretely relates to high -speed overtorque protection device, including adaptor flange, bearing and jackshaft, adaptor flange passes through the shear pin of circumference equipartition and is connected with the jackshaft, and adaptor flange passes through the bearing supporting with the jackshaft, is equipped with the polytetrafluoroethylene gasket in adaptor flange's the recess, 2 are no less than to the quantity of shear pin, and when super turning round is taken place when, the shear pin fracture, the thickness of polytetrafluoroethylene gasket is not less than 5 millimeters. Adaptor flange passes through circumference equipartition shear pin and is connected with the jackshaft, and at normal operation in -process, adaptor flange and jackshaft pass through shear pin transmission moment of torsion, and the two is relative the rotation not, when the moment of torsion of transmission exceeded the limit value, shear failure took place and splits for the shear pin, and at this moment, adaptor flange and jackshaft are thrown off thereupon, and the moment of torsion transmission is suspend, had realized surpassing the purpose of turning round the protection. The utility model has the advantages of simple structure, reasonable in design, convenient to use, safe and reliable, low cost, be convenient for installation and dismantlement.
Description
technical field:
The utility model belongs to power transmitting apparatus technical field, is specifically related to a kind of high speed overtorque protection device.
background technique:
In the evolution of drive technology, coupling connects the indispensable element of power equipment, and along with the development of industrial technology, production automation degree is more and more higher; In process of production owing to vibrating for a long time, a variety of causes such as impact may make the component in manufacturing mechanism loosen, occur and the phenomenon such as other action component is stuck, cause whole system to surpass to turn round, cause the destruction of unrepairable, cause equipment replacement thus, shutdown is stopped work etc. loses huge; Therefore, superly the protection problem attention causing people is gradually turned round.Occur to surpass for dynamic transmission system and turn round fault; it is main it is considered that the super of linkage member turns round disengaging gear; make moment of torsion can not continue to transmit; therefore there is the various super coupling turning round protection; be mainly used in printing machinery, package packing machine, chiller plant, automatic line, transport airplane industry, market demand is very large.The current several overload protection arrangement technology be applied are monopolized abroad in several companies hand, and domesticly mostly cannot be applied in high-speed drive system for the design and devdlop of overtorque protection device at present.
model utility content:
The utility model makes up and improves above-mentioned the deficiencies in the prior art part; provide a kind of high speed overtorque protection device that a kind of structure is simple, reasonable in design, esy to use, safe and reliable, with low cost, be convenient to installation and dismounting, can promote on a large scale and use.
The technical solution adopted in the utility model is: a kind of high speed overtorque protection device; comprise adapter flange, bearing and jack shaft; adapter flange is connected with jack shaft by the shear pin of circumference uniform distribution; adapter flange and jack shaft are supported by bearing, are provided with teflon gasket in the groove of adapter flange.
The quantity of described shear pin is no less than 2, and when there is super turning round, shear pin ruptures.
The thickness of described teflon gasket is not less than 5 millimeters.
The beneficial effects of the utility model: structure is simple, reasonable in design, easy to use, safe and reliable, with low cost, are convenient to install and dismounting, are easy to promote on a large scale and use.Its major advantage is as follows:
1), described adapter flange is connected with jack shaft by circumference uniform distribution shear pin, and in normal operation process, adapter flange and jack shaft pass through shear pin transmitting torque, and the two does not relatively rotate; When the moment of torsion transmitted exceedes limit value, shear pin generation shear fracture and rupturing, now, adapter flange and jack shaft are thrown off thereupon; moment of torsion transmission is interrupted, and achieve the super object turning round protection, structure is simple, reasonable in design; safe and reliable, with low cost, economic and practical.
2), the design of described bearing; when the moment of torsion transmitted exceedes limit value and causes shear pin to rupture; bearing has the effect of rotating support; to ensure that adapter flange and jack shaft can relatively rotate; avoid the damage of other equipment and component, serve protective action, structure is simple; reasonable in design, safe and reliable.
3), the design of described teflon gasket; when the moment of torsion transmitted exceedes limit value and causes shear pin to rupture; can prevent adapter flange and jack shaft under the state of high speed rotating; there is sintering and cause the phenomenon that again engages; play the super object turning round protection further; reasonable in design, safe and reliable, economic and practical.
4), this overtorque protection device is applicable to and the flexible coupling such as diaphragm, membranous disc combinationally uses, and realizes the double action of overload protection and shafting compensation, reasonable in design, easy to use, with low cost, safe and reliable.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
With reference to Fig. 1, a kind of high speed overtorque protection device, comprise adapter flange 1, bearing 3 and jack shaft 5, adapter flange 1 is connected with jack shaft 5 by the shear pin 4 of circumference uniform distribution, adapter flange 1 and jack shaft 5 are supported by bearing 3, are provided with teflon gasket 2 in the groove of adapter flange 1; The quantity of shear pin 4 is no less than 2, and when there is super turning round, shear pin 4 ruptures; The thickness of teflon gasket 2 is not less than 5 millimeters.Described adapter flange 1 is connected with jack shaft 5 by circumference uniform distribution shear pin 4, and in normal operation process, adapter flange 1 and jack shaft 5 are by shear pin 4 transmitting torque, and the two does not relatively rotate; When the moment of torsion transmitted exceedes limit value, there is shear fracture and rupture in shear pin 4, now, adapter flange 1 and jack shaft 5 are thrown off thereupon, and moment of torsion transmission is interrupted, and achieves the super object turning round protection; The design of described bearing 3, when the moment of torsion transmitted exceedes limit value and causes shear pin 4 to rupture, bearing 3 has the effect of rotating support, to ensure that adapter flange 1 and jack shaft 5 can relatively rotate, avoid the damage of other equipment and component, serve protective action; The design of described teflon gasket 2, when the moment of torsion transmitted exceedes limit value and causes shear pin 4 to rupture, can prevent adapter flange 1 and jack shaft 5 under the state of high speed rotating, sintering occur and causes the phenomenon that again engages, playing the super object turning round protection further; This overtorque protection device is applicable to combinationally using with the flexible coupling such as diaphragm, membranous disc, realizes the double action of overload protection and shafting compensation, reasonable in design.Structure of the present utility model is simple, reasonable in design, easy to use, safe and reliable, with low cost, is convenient to install and dismounting, is easy to promote on a large scale and use.
