The invention relates to a method for producing an adjustment fitting (1), particularly for a vehicle seat, comprising an outer wheel (4) that can be associated with a first fitting part (2), said wheel having inner toothing (16), and comprising an inner wheel (7) that can be associated with a second fitting part (3), said wheel having outer toothing (16), wherein the inner wheel (7) having the outer toothing (16) is inserted into the outer wheel (4) having the inner toothing eccentrically to a rotational axis (A) in the manner of a wobble mechanism, wherein partial eccentric elements (30,32) are inserted rotatably with respect to each other in an eccentric receiving chamber (25) formed between the rotational axis (A) and the inner wheel (7) so as to produce variable eccentricity, wherein an transmission element (34) having an engagement means (60, 62, 64) for actuating the partial eccentric element (30,32) is inserted such that the engagement means (60, 62, 64) interacts with catch means (50, 52, 54) of the partial eccentric element (30, 32). In spite of the production tolerances of the components, overall higher quality and higher operational safety of the produced adjustment fitting are to be achieved. For this purpose, the geometry of the partial eccentric element (30, 32) is measured, and the geometry of the transmission element (34) is individually adapted according to the data of the measurement before inserting the transmission element (34).

A construction of coupling spline sections for connecting two gears (302,306) of a countershaft in an automatic transmission. A rotary hollow section (310) having an inner periphery formed with a spline section (312) which is coupled with the spline section (308) of the rotary shaft section (304) and a bearing (318) is disposed between a part of an outer periphery of the rotary hollow section and the support member (316). The spline section of the rotary shaft section and the spline section of the rotary hollow section which are disposed at least inside the bearing are coupled with each other in a loose state that the bearing (318) supported by the tubular section (310) can be free from any stress. The right end part of the spline coupling close to gear (306) has different diameters to cause press fitting state.The left end side with loose spline coupling can act as a guide to facilitate mounting.

The invention concerns a transmission mechanism between at least one accessory (1, 2) and the motoring members (3, 4) driving a rotorcraft rotor (5), selectively, individually or jointly. An intermediate shaft (13) is interposed between a main shaft (7) driving the rotor (5) and a secondary shaft (12) driving the accessory (1, 2) from a motoring member (3) assigned to its motorization. Said intermediate shaft (13) is directly engaged on the main shaft (7) and engaged on a pinion gear (23) driving the accessories via free wheels (16, 17), to enable the pinion gear (23) to be driven either from the motoring member (3) or from the main shaft (7) in combined motorization with the rotor (5), itself driven by the motoring member (4) or in autorotation in case of failure of the two motoring members.
