New leak-free kits for heavy-duty gearboxes

After a lengthy development process, extensive testing of a gearbox fitted with the new technology showed that all components received sufficient lubrication and, most importantly, without any oil leakage. The operational temperatures were also found to be significantly lower, indicating reduced power losses of up to 14 per cent.

Overall the results of the tests showed that the new product operated better than the standard configuration. After delivery to Tubelines a gearbox fitted with the new leak-free kit passed all testing protocols and was eventually installed on an escalator where it has been operating satisfactorily at a busy station without any issues.

Commenting on the project, Roger Godson, of Renold Gears, says: "We're very proud to have been invited to develop a leak-free gearbox solution for Tubelines and to have made a contribution to significantly reducing the maintenance of escalator drives on the London Underground."

Whilst initially designed for heavy load escalators at underground stations the new leak-free gearbox technology is well suited to a wide range of heavy-duty industrial applications including, conveying, mining and quarrying, cement manufacture, pumping, water and waste water treatment, metal manufacture and power generation etc.
