Power management company Eaton has announced an extension to its fluid lubrication
service maintenance interval for its Procision line of medium-duty dual clutch transmissions for school bus applications that will lower or even eliminate fluid changes.
A specially-designed rear tail piece allows the new pipe to be easily pulled into place with fluid lubrication assist.
We also developed accessories and support equipment for use in the small-diameter splitting process, including a pipe-handling reel, fluid lubrication mixing and delivery system, HDPE pipe cutting equipment, pneumatic tool handling devices and additional items to help make the entire process as easy and user friendly as possible" he said.
The specific cutting force is found lower at a cutting velocity of 200 m/min except for fluid lubrication
and reported it to be a critical speed for brass machining.
Its unique grid-sensing patented technology detects all conductive materials, including non-magnetic particles, in non-conductive fluid lubrication
The fluid wedge angle between the sliding surfaces was calculated with a finite element method analysis and then used in the average Reynolds equation from Patir and Cheng (1978, 1979) to analyze the fluid lubrication on rough sliding surfaces.
It is postulated that the thrust slide-surfaces are under a state of mixed lubrication composed of fluid lubrication and solid friction.
Finally, within the framework of the developed theoretical model, detailed examination of the effect of the ratio of fluid lubrication to solid friction on the resultant friction coefficient, bearing load capability, and bearing clearance was undertaken to further clarify the essential role mixed lubrication plays in enhancing the lubrication characteristics of thrust slide-bearings in scroll compressors.
The original slider mechanism needed fluid lubrication to operate smoothly over its 300,000-cycle product life.
The challenge was to eliminate the need for any type of fluid lubrication and still maintain satisfactory functional performance," Shareef said.
The new design was tested for 300,000 cycles of operation and it performed satisfactorily without fluid lubrication.
Results (figure 5) for dry sliding of a steel ball on a rubber pad show a gradistill near to - 1/3; viscous silicone fluid lubrication
changes the gradistill to nearly +1/3.
