Couplings continuously lubricated

The major inspections should also include detailed inspections of any couplings in the train. Gear couplings should be disassembled and teeth inspected for indications of problems. The most common failures encountered with continuous lubrication-type gear couplings are ... 

When continuous lubrication is called for, the couplings should be supplied witli oil filtered to a minimum of 2 microns. Experience shows that filtering to K micron is possible and desirable. Usually this is done with a separate filter however, the whole system may be filtered to this level. The oil quantity furnished, per gear mesh, should be 3 gpm minimum. 

When specified or if recommended by the vendor and approved by the purchaser, a pressure lubrication system shall be furnished to supply oil at a suitable pressure to the pump bearings, the driver, and any other driven equipment, including gears and continuously lubricated couplings. 

The surface treatment chemistry of glass fiber is normally tailored to match the product function. Reinforcement size chemistries must be compatible with a multitude of processes and with the composite material end-use performance criteria. Processes such as injection molding require chopped fibers with compatibility for thermoplastic compounds. Filament winding and pultrusion require continuous fibers with utihty in thermoset and thermoplastic compovmds. Typically three basic components cue used with glass size chemistries a film former, lubricant, and coupling agent. Readers are directed to the patent literature or [1] and [2] for more specific details. 

Gear couplings are one type of mechanical-flexing coupling, and there are several ways to lubricate them grease pack, oU fill, oil collect, and continuous oil flow. Either grease or oil can be used at speeds of 3,600 rpm to... 

In some of the experiments, a lubrication system (Unist Standard Cool-Lubricator) was used to provide a continuous supply of lubricant onto the rake face. This supply, in the form of an air-mist, was controlled by an air metering screw. The cutting fluid, Cool-Lube 2210, was delivered to the tool rake face as a spray through a mix nozzle that was coupled to a co-axial air hose. Cool-Lube 2210 (Triglycerol Propylene glycol esters of C8 CIO acid) is a vegetable-based metal cutting lubricant.
