Abstract
The utility model relates to a brake for a curtain rolling machine of a big-arch shelter. The brake comprises a brake disc and a brake shoe piece matched therewith, wherein the brake disc is mounted on the power input shaft of a reducer, and a rolling body is arranged on the brake disc. When the power input shaft of the reducer rotate forwardly, the brake disc is in a free state and the brake is in an off state; when a belt pulley stops rotating, a downward pulling force is generated by a big-arch shelter rolling roller due to gravity, to apply reverse rotation force to the power input shaft of the reducer, so that the power input shaft of the reducer rotates reversely and the belt pulley and the power input shaft of the reducer perform relative reverse rotation. Therefore, the belt pulley gets close to the brake disc and compresses the rolling body, the power input shaft of the reducer is fixedly connected with the brake disc, the power input shaft of the reducer drives the brake disc to rotate reversely, the brake shoe piece is positioned in a brake slot of the brake disc, and the brake shoe piece inhibits the reverse rotation of the brake disc to realize brake action. The brake has the advantages of simple structure, low manufacturing cost, and safety and reliability in use.
