Abstract
Lubrication for a rotary shaft positioned within the upper region of a blast furnace is accomplished by mounting a mechanically actuated pump for rotation with a reduction gear box through which the rotatable shaft is driven. The pump is periodically operated by means of an adjustable cam plate mounted on a sector gear which is affixed to the rotatable shaft; torque being transmitted to the shaft via the sector gear which is driven by a pinion coupled to the reduction gearing.
