Detailed Description
In order to make the purpose and technical solution of the embodiments of the present invention clearer, the following description will clearly and completely describe the technical solution of the embodiments of the present invention by combining the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments, which can be obtained by a person skilled in the art without any inventive work based on the described embodiments of the present invention, belong to the protection scope of the present invention.
As shown in fig. 1: a roller overload prevention device for a belt conveyor mainly comprises a driving wheel 1, a driven ring 2, a driving shaft 3 and a retractable ball mechanism 4;
a driving shaft 3 is arranged in the center of the driving wheel 1, the driving shaft 3 is driven by an external driving mechanism to rotate, and a retractable ball mechanism 4 on the driving wheel 1 is meshed with the driven ring 2 so as to drive the driven ring 2 to rotate; the driven ring 2 is used for driving a belt pulley on the belt conveyor to rotate.
In order to better exert the engagement degree of the telescopic ball mechanisms 4 and the driven shaft 2, under the condition of not increasing the cost, the number of the telescopic ball mechanisms 4 is at least 6, the torque transmission of the motor can be exerted to the maximum, and the maximum transmission efficiency is provided.
As shown in fig. 2: the telescopic ball mechanism 4 comprises a groove seat 41, a spring 42, a ball 43 and a support 5; the groove seat 41 is arranged on the outer circumferential surface part of the driving wheel, a ball cavity 44 is arranged in the groove seat, the bottom end of the ball cavity 44 is provided with a spring 42, two sides of the spring 42 are provided with support pieces 5, and the bottom end of the ball 43 is in contact with the spring 42. The inner circumferential surface of the driven ring 2 is provided with an arc-shaped groove 21, and the balls 43 of the telescopic ball mechanism are embedded in the arc-shaped groove 21.
