Title:	Oil pots for Hepco ring lubrication

Problem

The expected life of the ring slideway has decreased due to the lack of oil being present in the felt wipers which are in contact with the ring.

Solution

After working out cycle times on our application with supplier it has been determined that the oil remains with in the wiper felts for a minimum of 3 months so oil pots have been introduced which can be topped up every 2 months to ensure lubrication is present on the ring at all times .

By drilling through into the rear of the top 2 wipers an oil way can be created allowing an oil pot to act as a reservoir.

A simple piece of marking out can be used to put the hole in the correct place and as long as care is taken to remove swarf from drilling there should be no or very little contamination of aluminium swarf.

Everybody will be issued with drills, taps and drill jigs very soon so that this can be done when a machine service is undertaken and the aim is to get all variants of flowlines along with Ecolines upgraded as soon as possible.

Method

The depth of hole to be drilled has to be done to a depth of 36mm; the main aly backplate is 25mm the spacer block underneath the wiper is 5mm and the distance from base of plastic wiper to felt is 6mm. en none 0
