Translation of "Unrund laufen" in English

In particular, the problem of balance frequently occurs, so that the known rotating piston machines frequently run very out of round, which on the one hand causes vibration and noise, and on the other hand also subjects the bearings to very high stresses.

The problem, however, is that, as the tool is being removed from the bore hole, the pilot or central drill comes out of the pilot or central bore hole, with the result that the tool again tends to run irregularly while it is being removed.

Since the pipe 1 in the clamping device is clamped with its outer surface, the inner tube surface relative to the exterior tube surface may be eccentric and can rotate non-circularly.

Undesirable vibrations can occur for example upon a cylinder turn-off of the engine, when one or several of the cylinders of the engine are turned off, wherein the engine can run out of round.

As a result, non-concentric operation of the ink roller can advantageously be compensated for.

Subsequently the default value is increased until non-true running is detected again.

This produces noises and causes an uneven run of the flywheel.

If at one of the plugs, the uneven run does not get worse, it's about this cylinder.

For this purpose, a vibration sensor is used, which already stops the machine in case of minor untrue running.

The untrue running of the guide rolls can lead to an irregular supporting of the strand, and thus, to strand defects or flaws.

Thereby there is formed between ring plate 17 and collar 11 a rotary capacitor whose capacitance is constant during rotation of the shaft at least substantially, i.e. apart from untrue running caused by the suspension of the shaft.

Since the plunger should be freely movable in an axial direction as a result of its function, an imprecise guidance of the tool shaft having untrue running of the tool can occur, particularly given an imprecision in the manufacture and fit.

Moreover, the large volume of chips means that the chips push the tool away from its rotating longitudinal direction and cause the tool to run in a "non-round" manner.

Exceeding certain pitch dimensions is not desirable, as this generates uneven running of the chain through the deflection radius, especially when links with very different lengths are connected in alternating fashion.

This speed SDZ lies outside the maximum true running speed RDZ so that within the framework of the algorithm explained with reference to FIG. 3, the speed DZ is increased with a maximum provided default value i.e. with a maximum slope until such time as a non-true running of the recirculation pump is detected for the first time.

In the example of FIG. 5 the default value VW now remains at its maximum value VWM until there is renewed non-true running.

Also essential for the operation is the radial mobility of each of the sealing discs which makes possible the adjustment to drill tolerances, inclined positions, out of center running, etc., without impairing the operation of the drill or the sealing means.

If during the recirculation of washing fluid by means of the true running monitoring unit 27 a non-true running of the circulating pump 22 is detected, the collection device 21 can for example be filled up with additional washing fluid S by opening the inlet valve 18, so that the fill level of washing fluid S in the collection device 21 rises and the circulating pump 22 runs true as a result.

In this way, if there is a change from true running to non-true running or from non-true running to true running a provisional approximation to that speed is bought about at which true running is still possible with the amount of washing liquor present in each case.

Even in the case of only a small eccentricity or ovality of a component in one of the two planetary gear sets, radial warping and uneven running inevitably occur, in conjunction with increased wear of the radial support and gearing, as well as increased operating noise.
