Custom designed gear units
12 August 2019
Renold Gears has recently worked closely with a major manufacturer of mining equipment to design heavy-duty custom gear units that will provide longer service life for its customers and significantly reduce the cost of ownership by cutting downtime and maintenance.
Log washers are used in the mining and quarrying of aggregates to remove the earth that clings to the small stones and sort them into predetermined sizes. The gear units on the log washers are critical components as failure results in the loss of production and a significant maintenance operation to remove and repair them. Renold Gears was contacted to design a gearbox with greater robustness, reliability, and with a longer service life than those on comparable log washers.
Working with designers at the log washer manufacturer, Renold Gears was able to design new units with an identical footprint to the incumbent supplier’s, but with features that made them easier to install and remove for maintenance. Better quality seals and bearings, and a higher grade material for the gears and shafts enabled Renold to predict a service life of at least 30% longer than the previous units.
