        Lubricating Oil Demand Computing

        Use the occasion The formula Example
        ?
        Ball bearings
        Oil demand F ( cc / hr ) = 0.04 x Bearing diameter x bearing number Suppose there is a ball bearing, bearing diameter of 8, seeking hourly fuel injection.

        F = 0.04 x 8 x 1 = 0.32 ( cc / hr )

        ?
        Bearing
        Oil requirement F (cc / hr) = 0.0023 x bearing contact with the shaft diameter x length Suppose there is a slide bearing, shaft 8, the contact length of the shaft 10, seeking hourly fuel injection.

        F = 0.0023 x 8 x 10 = 1.84 ( cc / hr )

        ?
        Smooth bearing track
        Level:Oil requirement F (cc / hr) = 0.0017 x slide length x width slider

        Vertical:Oil requirement F (cc / hr) = 0.006 x slide length x width slider

        Suppose you have a smooth dynamic bearing upright, slide length 10 width of 4, seeking hourly fuel injection.

        F = 0.006 x 10 x 4 = 0.24 ( cc / hr )

        ?
        Cylindrical sliding bearing
        Oil requirement F (cc / hr) = 0.0023 x shaft diameter x shaft length Suppose there is a cylindrical rolling body diameter of 8 to 10 long, seeking hourly fuel injection.

        F = 0.0023 x 8 x 10 = 1.84 ( cc / hr )

        ?
        Linear Slides
        Oil requirement F (cc / hr) = 0.0012 x length x Slider Slider Number Suppose there is a linear slide, slide a length of 8, the slider number is 2, seeking hourly fuel injection.

        F = 0.012 x 8 x 2 = 0.19 ( cc / hr )

        ?
        Cam
        Oil requirement F (cc / hr) = 0.013 x circumference x width Suppose you have a cam mechanism, the cam circumference 20, a width of 2, seeking hourly fuel injection.

        F = 0.013 x 20 x 2 = 0.52 ( cc / hr )

        ?
        Gear
        Oil requirement F (cc / hr) = 0.046 x pitch diameter x tooth width Suppose there is a spur gear, pitch circle diameter of 8, tooth width of 2, seeking hourly fuel injection.

        F = 0.046 x 8 x 2 = 0.74 ( cc / hr )

        ?
        Chain
        Oil requirement F (cc / hr) = 0.008 x chain length x width Suppose you have a chain length of 30, chain width is 0.8, seeking hourly fuel injection.

        F = 0.008 x 30 x 0.8 = 0.19 ( cc / hr )
