Charles & Hunting Variators
Simple, practical and robust, Charles & Hunting variators are in use throughout many areas of Australian industry, the majority of which still performing faultlessly.
Charles & Hunting Friction Cups
In mechanical variator design, the variation of speed is effected by moving a driving disc across the face of the friction cup, which gives stepless variable speed. As a result, the friction cup becomes the wear part; designed to be replaced after it has worn out (usually between 5,000 and 10,000 hours).
Friction cup drive surfaces run completely dry and have a relatively long life expectancy depending on the application. As an expendable item – similar to the tyres of a motor vehicle – the friction cup is inexpensive to replace.
There are four sizes of friction cups in the range:
– Size 1: 3″ diameter
– Size 2: 4-1/2″ diameter
– Size 3: 5-1/2″ diameter
– Size 4: 7″ diameter
