Our choice of Bearings

These are angular contact ball bearings that have precision ceramic balls fitted into a precision steel race. This arrangement offers several distinct advantages over bearing-steel balls.
Ceramic balls have 60% less mass than steel balls. This is significant because as a ball bearing is operating, particularly at high rotational speeds, centrifugal forces push the balls to the outer race, and even begin to deform the shape of the ball. The deformation leads to rapid wear and bearing deterioration. A ceramic ball, with less mass, will not be affected as much at the same speed. The result is that much higher rotational speeds are possible. Acceleration and deceleration times are reduced as well.
Ceramic balls do not react with the steel raceways. One of the modes of bearing failures is surface wear created by microscopic cold welding of ball material to the raceway. The cold welds actually break as the bearing rotated, creating surface roughness that leads to heat generation and bearing failure. Ceramic balls drastically reduces this mechanism, resulting in longer bearing life.
Due to the nearly perfect roundness of the ceramic balls they generate much less heat as they rotate, which results in longer bearing life. Also, vibration levels are lower when compared to steels balls.
Less lubrication is required. Hybrid ceramic bearings are more tolerant to lack of lubrication.

We build unusual projects BlueBird K7

Read more about this unusual project we undertook as we grew up In the North of England and watching DC when 7 yrs old it was a fascinating project to undertake and provide her with JJ3000 jet power was even better...

With several customers now building there own K7's we may have started a trend for constructing this fantastic model..*

News 4th January 1967...

Donald Campbell killed at 300mph
On 4 January 1967, weather conditions were finally suitable for an attempt. Campbell commenced the first run of his last record attempt at just after 8.45 am. Bluebird moved slowly out towards the middle of the lake, where she paused for a brief second as Donald lined her up. With a deafening blast of power, Campbell now applied full throttle and Bluebird began to surge forward. Clouds of spray issued from the jet-pipe, water poured over the rear spar and after a few hundred yards, at 70 mph, Bluebird unstuck from the surface and rocketed off towards the southern end of the lake, producing her characteristic comet’s tail of spray. She entered the measured kilometre at 8.46. Leo Villa witnessed her passing the first marker buoy at about 285 mph (459 km/h) in perfect steady planing trim, her nose slightly down, still accelerating. 7.525 seconds later, Keith Harrison saw her leave the measured kilometre at a speed of over 310 mph (500 km/h). The average speed for the first run was 297.6 mph (478.9 km/h). Campbell lifted his foot from the throttle about 3/10 of a second before passing the southern kilometre marker. As Bluebird left the measured kilometre, Keith Harrison and Eric Shaw in a course boat at the southern end of the measured kilo both noticed that she was very light around the bows, riding on her front stabilising fins. Her planing trim was no worse than she had exhibited when equipped with the Beryl engine, but it was markedly different to that observed by Leo Villa at the northern end of the kilometre, when she was under full acceleration. Campbell had made his usual commentary throughout the run.

Turbine Wheel Balance

Turbine Wheel Balance

238.00 / 290.36

The balancer works with the aid of Piezo transducers and operates on 12 voltssmooth DC input. It works on any size wheel of micro turbines.

How does the Balancer work? Taken from the Internet...for Ref only

Each rotating mass will cause a centrifugal force, pointing away from its rotational axis. In the ideal case that every “mass segment” is countered by an equal mass on the other side of the rotational axis, there will be no resulting force (except gravitation) that needs to be carried by the shaft or the bearings during steady rotation.

But due to manufacturing tolerances or uneven distribution of alloy components during casting, all rotating components will reveal a more or less severe degree of imbalance. This will cause a “vibrating” force exerted to the bearings of the rotor and hence can be measured by force- or translation-transducers attached to the bearings.

As a typical translation-transducer a magnetic transducer will require significant movement to generate a reasonable output voltage, thus demanding for a “soft” suspension with the accompanying low resonant frequency, well in the range of rotational speeds. So I didn’t choose one of these in my balancer design.

A piezoelectric transducer measures force and is a very “stiff” device, and by arranging two in a push-pull arrangement the elastic constant will still be increased. The problem is that these transducers can be considered from the electrical point of view as a variable voltage source (depending on the applied force) in series with a capacitor (depending on the material properties and the size). In conjunction with the following high-impedance buffer's input resistance this will form a high-pass filter with a characteristic time constant (T=R*C). Only if the period of the rotational frequency is well above this time constant the output signal will be in phase with the force applied to the transducers. But the time constant achievable in my balancing setup will be around 1s, thus all balancing RPMs above about 500/min will be fine.

Now arises the question: How is the position and amount of imbalance to be determined?

This purpose serves a trigger circuitry with a variable level. It is a simple voltage comparator, driving a constant current source as LED driver. The inverting input of the comparator is connected to a variable voltage source while the noninverting is fed with the output of the transducer/buffer assembly.

If this "imbalance signal" increases above the trigger level momentarily the LED will be lit.

The trigger level will then be set to a value that only the most positive part of the imbalance waveform will exceed the trigger level. If the LED is pointed to the wheel to be balanced, this seems to be standing still (stroboscopic effect). If there has been a mark placed on it before (or has already been present), you can stop the wheel and place it statically in the position that has been spotted with the LED.

In this position the "heavy side" of the wheel will point directly to the transducer that causes the LED to light when pushed on (the "+" transducer).

Now a counterweight will be attached to the other side of the wheel (usually I use textile adhesive tape) and the balance re-checked. During this process the trigger level will have to be set lower each time, as the imbalance decreases. When the vibration caused by imbalance approaches the noise level generated by the bearings, it becomes difficult to find a trigger level setting that will give a "standing" wheel display, then I usually stop and grind some material off the wheel at the side opposite from the counterweight. After that I remove all the tape and start over again to check if I took the right amount of material off.

This method requires some experience but it is possible to detect a difference with a piece of tape the size of 1mm², depending on the condition of the bearing surfaces of the shaft. And you'll get balancing finished in a reasonable time compared to other “homebrew” methods.
