Abstract
The engine of a mobile power crane-excavator is utilized as a source of heat to soften grease so that it may be applied to the open gears on the machine, even at low ambient temperatures. Heated water from the vehicle engine is caused to flow in heat transfer relationship with cold grease through a multi-conductor hose to provide a pre-heat of the grease. The heated water is caused to heat a metallic nozzle through which the pre-heated grease flows, thus creating a final heating of the grease up to the desired temperature. Air supplied through the nozzle causes the grease to be sprayed onto the gear. The remote supply tank for the grease may also be pre-heated with hot water from the vehicle engine.
Claims8
In a mobile power crane-excavator having operative mechanism including exposed gears:
- (a) a frame,
- (b) a water cooled internal combustion engine mounted on said frame and with said engine providing a source of heated water,
- (c) means connecting said engone to said operative mechanism for driving the latter,
- (d) a source of grease for application to said gears,
- (e) a gear greasing spray assembly disposed adjacent a said gear,
- (f) and means for transporting both grease from said source and heated water from said engine into closely adjacent heat transferring relationship at said spray assembly so that the traveling grease is lowered in viscosity before being sprayed onto the said gear.
