C & H – Charles and Hunting
Charles and Hunting geared motors and variable speed drives were – for a long time – a staple of the Australian industrial landscape.
The Charles and Hunting range included:
- In-line helical spur reducers
- In-line helical spur gearmotors
- Right angle worm gearmotors
- In-line helical spur variators
Part of the strength of the C & H range was the dual-reducer gearmotor, which enabled very high reductions in a reasonably compact unit. Indeed, the H3R in-line helical-spur reducer was available with an overall ratio of up to 107000:1!
Nowadays, extremely high ratios are normally achieved by using a planetary gearbox and matching it with either a bevel-helical or shaft mounted reducer.
C & H Variators
Charles and Hunting may be most well known for their inline variators. With 6:1 variation up to 0.37kW and 5:1 variation to 4kW, the range was both substantial and near-ubiquitous in Australian manufacturing for decades.
Power Transmission History
Charles and Hunting’s factory was situated in Wangara Road, Cheltenham, before relocating to 79-81 Cochranes Road, Moorabbin (now occupied by Fontelle.)
Many staff who have been involved in the industrial power transmission industry have dealt with Charles and Hunting in one way or another over the years, and we salute the position that C&H occupied.
