EPR Series Foot Mounted Helical Gearbox

EPR Series Foot Mounted Helical Gearbox

EPR series helical gearbox adopts an integral casting box, which has good structural rigidity and is easy to improve the strength of the shaft and the life of the bearings. The installation methods of the EPR series helical gear reducer include foot installation and flange installation, foot installation type is more widely used. As its structure is compact, it saves a lot of space. Its average efficiency is 96% for the double-stage type, 94% for the three-stage type, and 85% for the RDF-R/R combination type.EPR series gearboxes are widely used in the light industry, food, beer and beverage, chemical industry, escalator, automatic storage equipment, building materials machinery, iron and steel metallurgy, environmental protection, power plants, coal, mining, papermaking, wood-based panels, automobiles, ports ( Airports, terminals), tobacco machinery and other fields.
