Bases of the gramophone technology

By any pictures the parts of the gramophone are explained and some advices are given for the trouble shooting.
Most gramophones are constructed similarly and I hope to be able to help with my limited state of experience other gramophone friends.

The regulator

The regulator for the speed is from central importance:
The regulator snail is driven by the turntable wave,
The faster it turns, the more the take-up motion weights strive outwardly.
These pull the regulator disc against the brake felt about the take-up motion feathers.
The farther this is removed from the regulator snail, the higher the possible speed.

The regulator disc is a very frequent cause for disturbances: Frequently deposits on her are to be found.
These care for tackers of the drive. If the disc is cleaned, results in one substantially quieter run of the drive. With discs from injection moulding (gray metal) can also be found that this corrodes strongly or even spoiled or have torn. Here only remplacement helps. Also are to be drawn with all parts from injection moulding screws only with a lot of feeling and caution! Attention is to be given also to the brake felt: if this is hardened or is covered, results also in the disturbing sounds. Cleaning or renewing and subsequent oils put things right.
Particularly importantly is the setting of the bearings of the regulator shaft: two eccentric bearings cares for a multiplicity of set possibilities.
The axial gap, also the possibility aside shifting of the wave, should be little, it is too little raised friction and the shaft sticks or can be damaged. By turning the bearing bush one puts the intervention of the snail into the worm gear of the turntable. Also here a just still perceptible gap should be existing.
In addition one has the possibility, with worn or damaged worm gear of the turntable to place the snail by twisting the sockets about 180 degrees higher or deeper.
So the snail can intervene in a not yet used area of the worm gear and run perfectly.
(If was with the illustrated regulator the case)
Importantly it is to draw the clamping screws the bearing bushs full of feeling not to crush the bearing bush sen.
To the avoidance of eccentricities of the regulator should also be respected to an even setting of the weights. With running engine one approaches carefully and very slowly with a tallow pencil the circulating weights. Besides, the tallow pencil in the housing should lie close to be able to be led safely. The mostly deflect weight will touch first the pen and get a bit of paint. With this weight the regulator feather is to be shortened. For this purpose almost each of these feathers has a long hole at an end. The screw is solved and the feather is shifted around a small amount outwardly. Tighten and the whole repeat, since the weights circulate evenly.
A very weighty problem can represent the sticking of the regulator disc on the regulator shaft. The engine also in fully wound up condition not or only difficultly - can thereby turn the consequence: One winds farther up, in the hope him free-got shut! It should be checked always whether the regulator disc can easily be shifted along on the wave. (Experiences Itself!)
