Abstract: A method for assembling an electric motor (10) having a stator (34) and a rotor (32). It is endeavored to keep the air gap (38) as narrow as possible, in order to achieve good efficiency of the motor (10). However, component tolerances and assembly errors require generous dimensioning in order to avoid possible contact between the stator (34) and the rotor (32). To improve the accuracy of assembly, is proposed, during the insertion into one another of the rotor (32) and the stator (34), a centering aid (40, 42) is introduced into the air gap (38) at at least three points, the rotor (32) and the stator (34) are subsequently fixed in relation to one another and finally the centering aid (40, 42) is pulled out through openings (48) in the motor housing (20, 30).

Abstract: A worm-gear has an electric motor, which drives a worm, which meshes with a worm-wheel. Hitherto both the motor shaft and the output shaft have been mounted in a housing which, for assembly reasons, only permits a sliding fit between the motor shaft and its bearings. In order to simplify the assembly and permit the desirable interference fit between the motor shaft and its bearings, provision is made for both bearings for the motor shaft to be arranged in a first housing part, which, when the shaft is installed, can be separated from and re-connected to a second housing part, in which two bearings for the output shaft are arranged.

It is endeavored to keep the air gap (38) as narrow as possible, in order to achieve good efficiency of the motor (10). However, component tolerances and assembly errors require generous dimensioning in order to avoid possible contact between the stator (34) and the rotor (32).

Abstract: A worm gear unit having at least one worm shaft displaceable in the axial direction, means with which the worm shaft can be secured once in the axial direction in order to set the play being provided according to the invention, the means being permanently secured after the play has been set.

Abstract: A retention device 35 couples a load adjustment device to a throttle valve 2 which determines the output power of an internal combustion engine and is arranged fixed for rotation on a throttle-valve shaft 11. A clutch disk 8 of the clutch is connected fixed for rotation with the throttle-valve shaft 11 and also with the clutch 13, and is secured by means of a clamping device 35. The advantageous development of the clamping device 35 in combination with a coupling pin 10 makes it possible to mount and to lock the clutch anchor plate or clutch disk 8 against rotation without radial play, with the throttle valve shaft 11 entirely mounted. In addition, the clutch disk 8 can be axially secured in simple manner.

Abstract: A setting element (9) has, as handle (18), a web which is connected via a place of intended breakage (19) to the rest of the setting element (9). As setting part (17) there is provided an eccentric which effects the required setting movement by the turning of the setting element (9). After a desired setting has been reached, the handle (18) is broken off, thereby preventing further manipulation of the setting element (9).
