Renold gears up for Lanchester replacement

A Renold Gears product story
Edited by the Engineeringtalk editorial team Nov 19, 2008

When the gears used in the back axle of his Lanchester failed on a recent trip to France, Peter Noble turned to Renold Gears for replacement gears.

Driving through the fringes of the Gobi Desert in his 1955 Bentley Continental, Noble resolved to buy a car more suitable for such pioneering motoring roads and in 1991 bought a 1925 Lanchester 40HP Tourer.

This three-ton touring car with full weather protection was deemed to be an ideal transport for crossing continents on unused roads or desert tracks.

Last year Peter and his wife set out for a journey to Palmyra, Syria.

They had taken various routes across France, Italy, Greece and Turkey to Syria over the last 15 years in the Lanchester but in June 2007, just short of Clermont-Ferrand in France, a thunderous explosion below the car occurred on a steady incline along the Autoroute.

The rear axle worm and wheel had broken.

This was the first time in all of their travelling that they had to abandon the car to a transporter to have it sent home.

Noble said: 'Renold was at first a ray of hope and later a beacon of reality that our beloved Lanchester would once again be travelling those ancient roads in far-off places.

'Renold improved the metal by cutting the wheel from nickel bronze where Lanchester had used phosphor bronze and instead of the "hour-glass" principle favoured by Lanchester they used the Holroyd parallel worm design.

'After producing a computer model feeding in the weight of the car, the power of the engine, the gear ratios and so on, they gave an estimated life of 100,000km.' The replacement gears have now been fitted into the axle and tested on the UK's roads prior to a visit to India later in the year.
