Carrier roller rotation resistance measuring device

Abstract

The invention discloses a carrier roller rotation resistance measuring device and belongs to the technical field of carrier roller mechanics performance testing. The carrier roller rotation resistance measuring device comprises a machine frame, a suspension type carrier roller measurement module, a carrier roller driving module, a synchronous speed measuring module and a belt self-tensioning module, wherein a carrier roller is installed in a suspended mode, the influence on a measurement result of outside vibration can be avoided, a column type tension sensor is located between an upper suspension point and a lower suspension point, hinge pins of the upper suspension point and the lower suspension point are mutually perpendicular, and the stability of the measuring process is ensured. The synchronous speed measuring module is located on a carrier roller installing rack under the carrier roller and used for accurately measuring the instantaneous speed of the carrier roller and can adapt to carrier rollers of different roller diameters by itself. Under the joint effects of a weight box, a slide block and a slide rail, the self-adapting tensioning of a main drive belt and the vertical relation between the main drive belt and the carrier roller can be always ensured. Under the joint effect of a balancing weight of the belt self-tensioning module and an L-shaped lever, a toothed belt of a primary belt wheel mechanism can be always tensioned through a tensioning wheel, and rotation resistance measurement of the carrier rollers of different roller diameters can be achieved.

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...

[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
