- the holes in the rotor bell 10 can be part the holes of this circle exclusively as mounting holes 29 and another Part serve as locking holes. These two types of holes can be easier Differentiation also lie on circles with different radii. Then can the holes in the rotor bell 10 also have different diameters, e.g. the machining holes 36 have a larger diameter than that for the Spacers 37 provided holes.
- the installation of the motor 30 in the manufacturing plant for washing machines is similar simple as in the example of FIGS. 1 and 2.
- the rotor bell 10 is first on screwed the threaded stub 24 until the outer surface of the ring 32 on the Attachment eyes 31 comes to rest. Then this position is in proportion secured to the shaft journal 4 (screw or similar). If the mounting holes from the Locking holes are different, only the fastening screws 26 rotated through the processing holes 36 into the mounting eyes 31. Then the locking screws 36 and the spacer sleeves 37 are removed and sent to the manufacturer of the engine returned. If the mounting holes and the locking holes are designed the same, only some, e.g. three; the holes for locking by means of the spacer sleeves 37 and the locking screws 35 can be used.
- the stator support part 38 on a circumferential collar 39 is also equipped with excitation windings 40 and laminated cores which face poles 41 that can be magnetized via an air gap. These poles are fastened in the same way as in the examples described above on the inner circumference of the edge 42 of a rotor bell 43 which is provided with machining holes 44 for fastening screws 45.
- the area created by the overlapping flange 47 of the stator support part 38 serves as the labyrinth seal 46. There is no need for a special seal on the inside because this area is already dustproof due to the construction described.
- the stand support member 38 has a central guide sleeve 48, the outer cylindrical surface 49 together with the short inner cylindrical surface 50 of an annular bead 51 the rotor bell 43 forms a sliding fit (e.g. H7 / j6), which is used to secure the position the engine parts are used during transportation. In this securing position the engine parts are fixed with transport locking screws 52 and sit with their faces together.
- the laminated core of the field windings 40 is included offset inward from the poles 41, for example by 6 to 7 mm.
- the guide sleeve 48 forms with its inner cylindrical surface opposite the outer cylindrical surface the bearing sleeve 5 also has a sliding fit (e.g. also H7 / j6).
- a sliding fit e.g. also H7 / j6
- the guide sleeve 48 is pushed onto the bearing sleeve 5 and rotor bell 43 with its central hole in the serration of the stub shaft 53 led.
- the central shaft screw 54 is slightly tightened, and the transport locking screws 52 are unscrewed. After the mounting screws 45 are tightened, the shaft screw can also be tightened become.
- For the correct dimensional matching of the engine parts to each other in the installed condition provide the spacer 55 between the stand support member 38 and Support star 1 on the one hand and the spacer 56 between the rotor bell 43 and one Paragraph 57 on the shaft journal 4.
