Definitions

the invention relates to a mounting arrangement for runners on shafts of ignition distributors for internal combustion engines according to the preamble of claim 1.
Such an arrangement with a metal bushing and a clamping screw is therefore necessary in highly loaded ignition distributors, on the one hand to deflect the rotor and on the other hand to climb it up To prevent wave.
Such an arrangement acting as a locking mechanism for the cylinder guide is known for example from DE-OS 34 05 267 A1, in which the end section of the shaft has a line contact on the inner wall of the bushing.
the clamping screw has a drilling effect due to the high load, which in turn leads to surface deformations and consequently loosens the rotor from the shaft; Here, destruction of the internal combustion engine is not excluded.
the problem set out above is solved with technically simple means and achieved that the fastening arrangement does not loosen or loosen even under difficult operating conditions and consequently no damage is caused in this regard.
the invention is based on the idea of using the principle of double cylinder guidance used in so-called lathe hearts of lathes.
Claim 2 shows a technically simple way of producing the flattening. With claim 3 you achieve a favorable width of the flat surface.
FIG. 1 An embodiment of the invention is shown in the drawing and explained in more detail in the description of the figures.
the single figure shows an enlarged view of a rotor fixed to a shaft of an ignition distributor for internal combustion engines by means of a fastening arrangement in a partially sectioned bottom view.
the sole figure of an ignition distributor for internal combustion engines shows a shaft 10 with a rotation axis 11 and a rotor 12 made of insulating material with a finger 13 with an electrode 14 arranged transversely to the rotation axis 11.
a sleeve 15 protrudes from the finger 13 in one piece and coaxially with the rotation axis 11 , in which a metal socket 16 is inserted.
an internal thread 18 is arranged with an axis 21 extending radially to the axis of rotation 11 of the shaft 12, which interacts with a clamping screw 17.
This has a conical pressure part 19 and protrudes through an opening 20 in the sleeve 15, which runs parallel to the axis 21 of the clamping screw 17.
the end section of the shaft 10 has a conical recess 23 which receives the pressure part 19 of the clamping screw 17 and diametrically opposite this as a flat surface 22; this is parallel to the axis 11 of the shaft 10 and its extent transversely to the axis 21 is approximately 70 degrees of angle according to a double arrow 24.
the surface 22 of the casing 25 of the end section of the shaft 10 then forms two line contacts 26 with the inner wall 27 of the bush 16, if - As shown - the clamping screw 17 acts on the end portion of the shaft 10 according to arrow 28.
