    Another critical speed at mode 4 is observed at 7810 rpm (130 Hz) in dangerous vicinity of nominal shaft speed, but it has 30% damping - enough to safely ignore it. Analytically computed values of eigenfrequencies as a function of the shaft's rotation speed. This case is also called "whirl speed map". [4] Such a chart can be used in turbine design.

  4. Rotary union - Wikipedia

    en.wikipedia.org/wiki/Rotary_union

    The shaft is the component that carries the medium through the rotary union into the drum or roll. In many cases the shaft will turn with the drum or roll. In some cases, like in larger flanged rotary unions, the shaft may be stationary while the housing rotates. The bearings and seal are typically assembled around the shaft.

  5. Affinity laws - Wikipedia

    en.wikipedia.org/wiki/Affinity_laws

    The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...

    A golf club is a club used to hit a golf ball in a game of golf.Each club is composed of a shaft with a grip and a club head. Woods are mainly used for long-distance fairway or tee shots; irons, the most versatile class, are used for a variety of shots; hybrids that combine design elements of woods and irons are becoming increasingly popular; putters are used mainly on the green to roll the ...

    In Canada, the song reached the top 80 on the Canadian Singles Chart. "Even Flow" peaked at number 27 in the UK and number 22 on the Australian Singles Chart. It was a moderate top 20 success in New Zealand. Chris True of AllMusic called "Even Flow" "the somewhat less ballady more swaggering follow up to the breakout single 'Alive'." True said ...

  8. Engine balance - Wikipedia

    en.wikipedia.org/wiki/Engine_balance

    These take the form of a pair of balance shafts that rotate in opposite directions at twice engine speed, known as Lanchester shafts, after the original manufacturer. In V8 engines , the problem is usually avoided by using a cross-plane crankshaft , and a 180° or single-plane crankshaft is used only in high-performance V8 engines, where it ...

  9. Universal joint - Wikipedia

    en.wikipedia.org/wiki/Universal_joint

    The Cardan joint suffers from one major problem: even when the input drive shaft axle rotates at a constant speed, the output drive shaft axle rotates at a variable speed, thus causing vibration and wear. The variation in the speed of the driven shaft depends on the configuration of the joint, which is specified by three variables:
