Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The contact area of the braking band with the braking wheel depends on the width of the braking band, the diameter of the braking wheel and the connection position of the braking band with the unwinding frame. The contact area between the brake band and the brake wheel determines the dynamic friction force between the brake band and the brake wheel, and the brake band is generally arranged in a U shape. If the dynamic friction force is too small, the braking effect on the unwinding shaft is poor; the dynamic friction force is too large, so that the unwinding shaft is prevented from normally unwinding, and the film tension between the unwinding shaft and the winding shaft is too large. The elastic member contributes to the adjustment of the dynamic friction force.
The brake band inevitably suffers from lateral misalignment during use, and if the brake band is thin, local deformation of the edge of the brake band tends to occur, and the provision of the raised lines helps to reduce the above-mentioned problems of lateral misalignment and deformation. Further, the wheel surface of the brake wheel is wider than the brake band. Specifically, the convex strips on the surface of the brake band are arranged at equal intervals along the extension direction of the brake band.
The elastic member has an elastic force for adjusting a dynamic friction force between the brake band and the brake wheel. The elastic member is required to satisfy the basic conditions of connection with the connecting member and the end of the brake band, including but not limited to tension spring, elastic band cord, and elastic sheet, and the preferred elastic member is tension spring and elastic band cord based on the convenience of connection.
The elastic member may be separately attached to one end of the brake band or may be attached to both ends of the brake band. Furthermore, when the elastic part is connected to one end of the brake band, the elastic direction of the elastic part is consistent with the tangential direction of the motion track of the brake wheel, which is beneficial to prolonging the service life of the elastic part.
The idler wheel is attached to the brake band to increase the central angle of the brake wheel covered with the brake band.
The position of the idler wheel is adjusted through the wheel surface distance adjusting assembly, so that the deformation degree and the elasticity of the elastic piece can be adjusted conveniently. The wheel surface distance adjusting component can also be a cylinder, a hydraulic cylinder and the like connected with the wheel-leaning shaft.
