The cutter drive is from a pulley onto a chain wheel shaft, through a universal joint shaft to a sun and planet gear box to the cutter spindle. The housing for the chain wheel shafts is made up of three castings - the central casting is connected to the 5" spindle casting by a steel frame work, or possibly on a separate stand on the floor, the outer castings can be regulated for centre distance by varying the packings. The sun and planet gears are 16's pitch and Contd. | ||
