Embodiment Construction

[0016] exist figure 1 In this case, the rear wall 1 of the washing drum 2 supported in the lye container (here made of plastic) is fixedly connected to the drive shaft 3 . Only a part of the lye container is shown here, in which part the bearing housing 4 is integrated on the rear wall of the lye container. In this case, the bearing housing 4 is bored for the drive shaft 3 , which, together with the washing drum 2 , is movably mounted in the bearing housing 4 on two roller bearings 5 ​​and 6 . In this case, the inner rolling bearing 5 is protected from liquid from the lye container by a shaft seal 7 (shown only schematically here).

[0017] The drive shaft 3 has shoulders on the bearing points, which define the position of the rolling bearings 5 ​​and 6 during press-fitting. The other shoulder on the outer end of the drive shaft 3 , ie the end 8 facing away from the washing drum 2 , contains an external thread 9 which fits into an internal thread 10 on the flange 11 of the b...

Abstract

The domestic laundry treating machine according to the invention is preferentially a front-loading washing machine. Said machine has a washing drum (2) driven by an electric motor and a belt drive between the washing drum (2) and the electric motor, in which the washing drum (2) is firmly connected to a drive shaft (3), and the drive shaft (3) is connected to a pulley (12) of the belt drive, wherein the pulley (12) is provided with a flange (11) having an internal thread (10) in the region of the connection to the drive shaft (3). In addition, the end (8) of the drive shaft (3) facing away from the washing drum (2) is preferentially provided with a shallow pot-like depression (13) and has an external thread (9) engaging in the internal thread (10). Moreover, both threads (9, 10) are connected non-detachably, in particular bonded, to one another.

Description

technical field [0001] The invention relates to a household laundry treatment machine with a washing drum that can be driven by an electric motor and a belt drive between the washing drum and the electric motor, wherein the washing drum is fixedly connected to the drive shaft and the drive shaft is connected to the belt Pulley connection for transmission. The invention also relates to a method for assembling said machine. Background technique [0002] Modern domestic laundry machines, in particular washing machines, are increasingly being equipped with a vibration system which includes, for example, a lye container which can no longer be opened without damage for changing the washing drum. This has to do with the fact that modern constructions of vibration systems have become more durable and have suffered less damage in daily operation. However, if damage occurs thereon, it is more economical not to replace individual components or components, but to replace the entire vi...
