Embodiment Construction
[0074] The present invention is now described in detail with the aid of the accompanying drawings:
[0075] exist figure 1 The lead screw motor of the present invention is shown in a cut oblique view, in Figure 1a The lead screw motor of the present invention is shown in cross-sectional view. exist figure 2 with image 3 are enlarged and shown in Figure 1a Partial view of the lead screw motor in .
[0076] The housing parts 4 , 7 and 15 of the spindle motor are connected sealingly to the motor housing 1 of the motor comprising the rotor 2 and the stator 3 . An O-ring is preferably inserted at each connection point of the housing parts in order to ensure tightness even at overpressures of greater than, for example, 2 bar.
[0077] Housing part 4 accommodates a bearing 18 via which spindle 5 is supported. The lead screw is connected to the rotor shaft 2 via an axially pluggable coupling. The coupling has a claw 20 and a claw 22 between which a plastic star 21 is arran...
