In order to improve the security of the traditional clutch in some working condition and optimize its structure,this article mainly design a new security friction clutch,this type is in the characteristic of brief structure,light weight and little working electricity, and it can be connected with the input shafts of speed-reducer directly. It also can be widely used in the various input shaft such as mine and oil exploiting ,forging lathes in architecture, fishing boats and so on, which enable it good using and spreading value.
The structure of the security friction clutch design takes the brake-rod-shoe centrifugal friction clutch. This clutch is made of three components: driving parts, separating pats and output parts, in which driving shaft 4,arc rotor 8 , coupling 14 and some other pieces constitute the driving parts, holding cover 11,centrifugal shaft 1 ,torsion spring 12 consist of the separating parts, while the output parts is composed of outside drum wall 7 and 10,shaft cover 3.And the majority of the design involves the structure design and the fixing of dimension .
A new kind of security friction clutch that works reliable and secure is provided through this design.
