DEVICE FOR AUTOMATICALLY SUPPLYING GREASE OF SPLINE PART FOR WIRE DRUM OF HOT METAL CRANE

摘要

PURPOSE: An automatic grease supply apparatus of a spline part for a wire drum of a hot metal crane is provided to prevent wear of equipments, and to improve operability by automatically supplying lubricant between a spline of the hoist wire drum and a boss. CONSTITUTION: An automatic supply device of a spline part for a wire drum(1) is composed of a supply hole(12) formed between a spline shaft(10) and a boss(2); a rotary joint(22) fixed to a drum shaft(16) of the wire drum to rotatably connect the supply hole and a supply pipe(24); a pump(26) installed in the end of the supply pipe; a container(40) arranged below the spline shaft and the boss; doors(42b) opened and closed elastically and installed in the lower part of the container; an operating piece(48) connected to the door and turned around a fixing bracket(50); a support plate(62) connected to the lower part of the operating piece for repulsion; a driving sprocket(64) rotatably fixed on the supporting plate, and contacted to the outer periphery of the wire drum by a driving roller(72); and a driven sprocket(66) connected to the driving sprocket by a chain(68) and a pump shaft(70), and fixed in the lower part of the supporting plate. Wear is minimized by supplying lubricant automatically and continuously in driving the wire drum.
