Problems solved by technology

[0005] However, the rotation resistance value obtained by the above-mentioned idler rotation resistance measurement method is not accurate, and the international standard of rotation resistance and my country's national standard also show diametrically opposite conclusions. Therefore, there is an urgent need for a more effective and accurate The measurement method of the rotation resistance of the idler roller can solve the measurement problem of the rotation resistance of the idler roller

Abstract

A device for measuring the rotational resistance of a roller, belonging to the technical field of mechanical performance testing of rollers. The invention includes a frame, a suspended roller measurement component, a roller drive component, a synchronous speed measuring component and a belt self-tensioning component. The roller is installed in a suspended manner, which can avoid the influence of external vibration on the measurement results. The column pull force The sensor is located between the upper and lower suspension points, and the hinge pins of the upper and lower suspension points are perpendicular to each other, ensuring the stability of the measurement process; the synchronous speed measurement component is located on the roller mounting frame below the roller for accurate measurement. The instantaneous speed of the roller can adapt to rollers with different roller diameters; under the joint action of the counterweight box, slide block and slide rail, it can always ensure the adaptive tension of the main drive belt and the vertical relationship between the main drive belt and the roller; in the belt Under the combined action of the counterweight of the self-tensioning component and the L-shaped lever, the toothed belt of the primary belt pulley mechanism can always be tensioned through the tensioning wheel to meet the measurement of rotation resistance of idlers with different roller diameters.

Description

technical field [0001] The invention belongs to the technical field of mechanical performance testing of idler rollers, in particular to a measuring device for idler roller rotation resistance. Background technique [0002] As an important component of the belt conveyor, the idler roller plays the role of supporting the conveyor belt, reducing the running resistance of the conveyor belt, maintaining the sag of the conveyor belt within a certain range, and ensuring the smooth operation of the conveyor belt. [0003] However, during the actual use of the idler roller, the idler will inevitably produce rotational resistance, and the generation of rotational resistance will inevitably affect the performance of the idler. To study the influence of rotational resistance on the idler, it is necessary to be able to accurately measure The size of the rotation resistance provides a theoretical basis for the optimal design of the belt conveyor. [0004] At present, the method of measu...
