Among power transmission options, the belt drive\u2019s simple design<\/strong> and<\/strong> manufacturability<\/strong> make it a cost-effective alternative. SPX Cooling Technologies offers belt drives in many cooling tower models.<\/p>\n

New belt drives produce about 95 percent efficiency. Beyond its low initial cost, the belt drive\u2019s exposed components require frequent maintenance, so higher operating cost can be expected.<\/p>\n

A bearing and bushing hold it all together. This technology offers smooth and effective transmission of power between shafts, even if they are at a considerable distance. Regular belt lubrication and tensioning are required to ensure proper power transmission and cooling tower operation. Over time, as the belts stretch and wear, percent efficiency can dip to the low 90s or even lower, calling for more frequent replacement \u2013 once a year, typically. Maintenance professionals should conduct a monthly inspection to check proper belt tension and alignment, adequate lubrication, and signs of wear.<\/span><\/p>\n

Belt drives are often employed in cooling towers with lower horsepower requirements. Like a gear drive, the belt drive does not require a variable frequency drive (VFD). The Marley Geareducer\u00ae gear drive offers a more efficient alternative that provides energy, installation and maintenance cost savings.<\/span>[\/et_pb_tab][et_pb_tab title=”Downloads” _builder_version=”4.16″ body_font=”||||||||” body_font_size=”16px” body_line_height=”1.8em” tab_font=”||||||||” global_colors_info=”{}”]\n\n\n\n
