Description

Technical Field

[0001] The utility model relates to the technical field of centrifuge accessories, in particular to a centrifuge belt tensioning and adjusting device. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate components in a liquid and solid particles or a mixture of liquid and liquid. The commonly used transmission method in a centrifuge is belt drive, which can effectively alleviate vibration with its advantages of alleviating impact, reducing vibration, and stable transmission. Since the belt in the belt drive is elastic, although it can effectively protect other parts during transmission, it will slip during the transmission process. Since the belt is elastic, it will be continuously stretched when used for a long time. At this time, the belt of the centrifuge needs to be tensioned to ensure that it can continue to transmit.

[0003] Therefore, it is necessary to propose a technology to improve the above defects. Utility Model Content
